Assembly method for rotary engine

Claim 1

A method of assembling components of a rotary engine of the type having an outer housing body including a cavity, a rotor disposed in said cavity for relative rotation with said outer body, said rotor having a plurality of grooves with at least one groove containing a spring-biased seal member such that in the operation of said mechanism said seal member is urged into sealing engagement with a surface of said housing body, said method comprising providing a said rotor, and a said seal member and spring in substantially finished manufactured condition ready for assembly, applying a film of adherent lubricant composition to a surface of said seal which lies adjacent a wall of a said rotor groove in the operation of said engine, inserting said spring and seal in said groove and pushing said seal against said spring so that said seal is depressed in said groove below the normal operating position of said seal, said composition adhering to said groove wall and holding said seal in said depressed position while said rotor is placed in said housing, and then placing said rotor including said spring-biased seal in said housing, said seal subsequently being returned to its operating position by said spring, said composition being removable from said engine by vaporization and combustion during the operation of said engine.

Claim 2

A method of assembling components of a rotary engine of the type having an outer housing body including a cavity, a rotor disposed in said cavity for relative rotation with said outer body, said rotor having a plurality of grooves with at least one groove containing a spring-biased seal member such that in the operation of said mechanism said seal member is urged into sealing engagement with a surface of said housing body, said method comprising providing a said rotor, and a said seal member and spring in substantially finished manufactured condition ready for assembly, applying a film of adherent lubricant composition to a surface of said seal which lies adjacent a wall of a said rotor groove in the operation of said engine, inserting said spring and seal in said groove and pushing said seal against said spring so that said seal is depressed in said groove below the normal operating position of said seal, said composition adhering to said groove wall and holding said seal in said depressed position while said rotor is placed in said housing, and then placing said rotor including said spring-biased seal in said housing, said seal subsequently being returned to its operating position by said spring, said composition being removable from said engine by vaporization and combustion during the operation of said engine.

Claim 3

A method of assembling components of a rotary engine of the type having an outer housing body including a cavity for a rotor, a rotor disposed in said cavity for relative rotation with said outer body, said rotor having a plurality of grooves each adapted to receive a spring and a seal member such that in the operation of said engine a said seal member moves in a said groove and is urged by a said spring into sealing engagement with a surface of said housing body, said method comprising providing a said rotor and said seal members and springs in substantially finished manufactured condition for assembly, applying a film of adherent waxy composition to a surface of each said seals which surface will in the operation of said engine slide against a wall of a said rotor groove, placing each of said springs and its associated seal in appropriate grooves of said rotor, pushing in at least one of said seals agaiNst its spring so that said seal is depressed in its groove below the normal operating position of said seal, said waxy composition adhering to said groove wall to temporarily hold said seal in said depressed position while said rotor is placed in said housing, and then assembling said rotor in said housing, said seal being returned to its operating position after said assembly by the force of said spring overcoming the adherence of said composition, said composition being removable from said engine by vaporization and combustion during the operation of said engine.

Claim 4

A method of assembling components of a rotary engine of the type having an outer housing body including a cavity for a rotor, a rotor disposed in said cavity for relative rotation with said outer body, said rotor having a plurality of grooves each adapted to receive a spring and a seal member such that in the operation of said engine a said seal member moves in a said groove and is urged by a said spring into sealing engagement with a surface of said housing body, said method comprising providing a said rotor and said seal members and springs in substantially finished manufactured condition for assembly, applying a film of adherent waxy composition to a surface of each said seals which surface will in the operation of said engine slide against a wall of a said rotor groove, placing each of said springs and its associated seal in appropriate grooves of said rotor, pushing in at least one of said seals agaiNst its spring so that said seal is depressed in its groove below the normal operating position of said seal, said waxy composition adhering to said groove wall to temporarily hold said seal in said depressed position while said rotor is placed in said housing, and then assembling said rotor in said housing, said seal being returned to its operating position after said assembly by the force of said spring overcoming the adherence of said composition, said composition being removable from said engine by vaporization and combustion during the operation of said engine.

Claim 5

A method of assembling components of a rotary engine of the type having an outer housing body including a rotor cavity, a rotor disposed in said cavity for relative rotation with said outer body, said rotor having a plurality of grooves each adapted to receive a spring-biased apex seal member such that in the operation of said engine each of said apex seal members is urged into sealing engagement with a surface of said housing body, said method comprising providing a said rotor and said apex seal members and associated springs in substantially finished manufactured condition ready for assembly, applying a film of an adherent waxy composition to the side surfaces of said apex seals, inserting each of said apex seals and associated springs in a groove of said rotor, pushing each of said apex seals against its associated spring so that said apex seals are depressed in their grooves below their normal operating position, said composition adhering to the surfaces of said seals and said grooves so as to temporarily hold said seals in said depressed position while said rotor is placed in said housing, and then assembling said rotor and its spring-biased apex seals in said housing, each of said apex seals being returned to their normal operating position after said rotor has been assembled in said housing by the force of its spring overcoming the adherence of said composition, said compositon then being removable from said engine by vaporization and combustion during the operation of said engine.

Claim 6

A method of assembling components of a rotary engine of the type having an outer housing body including a rotor cavity, a rotor disposed in said cavity for relative rotation with said outer body, said rotor having a plurality of grooves each adapted to receive a spring-biased apex seal member such that in the operation of said engine each of said apex seal members is urged into sealing engagement with a surface of said housing body, said method comprising providing a said rotor and said apex seal members and associated springs in substantially finished manufactured condition ready for assembly, applying a film of an adherent waxy composition to the side surfaces of said apex seals, inserting each of said apex seals and associated springs in a groove of said rotor, pushing each of said apex seals against its associated spring so that said apex seals are depressed in their grooves below their normal operating position, said composition adhering to the surfaces of said seals and said grooves so as to temporarily hold said seals in said depressed position while said rotor is placed in said housing, and then assembling said rotor and its spring-biased apex seals in said housing, each of said apex seals being returned to their normal operating position after said rotor has been assembled in said housing by the force of its spring overcoming the adherence of said composition, said compositon then being removable from said engine by vaporization and combustion during the operation of said engine.
