Abstract
Abstract A multiway switch valve having a housing that includes a chamber and a plurality of channels merging into said chamber and terminating in coupling nipples at the outside of the valve; a channelled valve plug rotatably held in said chamber and adapted to assume a plurality of positions to interconnect selected ones of said channels, said plug has a sealing face in the shape of a spherical section; packing rings surrounding each channel opening in said chamber to provide a continuous fluidtight seal between said openings and said sealing face.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
214 words
A multiway switch valve, comprising, A. a valve housing, B. a valve chamber formed in said valve housing, C. a plurality of fluid-carrying housing channels formed in said valve housing, each said housing channel having a terminal opening merging into said valve chamber, D. a valve plug rotatably disposed in said valve chamber, said valve plug having a sealing face in the shape of a spherical segment, said sealing face being disposed solely at one side of an equatorial plane normal to the rotational axis of said valve plug and belonging to an imaginary sphere complementing said sealing face, E. a plurality of fluid-carrying plug channels formed in said valve plug, each said plug channel having a terminal opening on the surface of said plug, at least some of the last-named openings being disposed on said sealing face, F. means for effecting a fluid-tight engagement between at least some of said housing channel openings and said sealing face of said valve plug, G. means for pressing said sealing face in the direction of said axis against the housing channel openings opposite said sealing face and H. means for rotating said valve plug into any one of a plurality of positions to interconnect selected ones of said housing channels by means of said plug channels.
Claim 2
Dependent Claim
214 words
A multiway switch valve, comprising, A. a valve housing, B. a valve chamber formed in said valve housing, C. a plurality of fluid-carrying housing channels formed in said valve housing, each said housing channel having a terminal opening merging into said valve chamber, D. a valve plug rotatably disposed in said valve chamber, said valve plug having a sealing face in the shape of a spherical segment, said sealing face being disposed solely at one side of an equatorial plane normal to the rotational axis of said valve plug and belonging to an imaginary sphere complementing said sealing face, E. a plurality of fluid-carrying plug channels formed in said valve plug, each said plug channel having a terminal opening on the surface of said plug, at least some of the last-named openings being disposed on said sealing face, F. means for effecting a fluid-tight engagement between at least some of said housing channel openings and said sealing face of said valve plug, G. means for pressing said sealing face in the direction of said axis against the housing channel openings opposite said sealing face and H. means for rotating said valve plug into any one of a plurality of positions to interconnect selected ones of said housing channels by means of said plug channels.
Claim 3
Dependent Claim
26 words
A multiway switch valve as defined in claim 1, wherein the housing channel openings engaging said sealing face of said valve plug are annular in shape.
Claim 4
Dependent Claim
40 words
A multiway switch valve as defined in claim 1, wherein the housing channel openings that are in engagement with said sealing face of said valve plug are disposed in a circular array about the rotational axis of said valve plug.
Claim 5
Dependent Claim
49 words
A multiway switch valve as defined in claim 1, wherein said means for effecting said fluid-tight engagement includes packing rings each surrounding a housing channel opening and engaging said sealing face of said valve plug, said packing rings project from the wall face of said valve chamber inwardly thereof.
Claim 6
Dependent Claim
17 words
A multiway switch valve as defined in claim 4, wherein said packing rings are made of Teflon.
Claim 7
Dependent Claim
50 words
A multiway switch valve as defined in claim 4, wherein the wall face of said valve chamber and said sealing face of said valve plug are spaced from one another; the space defined by said faces is in continuous communication with a discharge channel constituting one of said housing channels.
Claim 8
Dependent Claim
60 words
A multiway switch valve as defined in claim 1, including a central depression provided in said valve chamber; said central depression is in continuous communication, on the one hand, with one of said housing channels and, on the other hand, with a centrally disposed plug channel; one opening of the last-named channel terminates on said sealing face of said plug.
Claim 9
Dependent Claim
32 words
A multiway switch valve as defined in claim 7, including a central cylindrical bearing stub integral with said valve plug and seated rotatably and in a fluid-tight manner in said central depression.
Claim 10
Dependent Claim
36 words
A multiway switch valve as defined in claim 1, including means generating a springing force in the direction of said axis for resiliently pressing said sealing face against the housing channel openings opposite said sealing face.
Claim 11
Dependent Claim
80 words
A multiway switch valve as defined in claim 9, including A. a closure covering said valve chamber and including a central opening, B. a setting pin integral with said valve plug and projecting through said central opening, said setting pin forming part of said means for rotating said valve plug and C. resilient ring means disposed about said setting pin and compressed between said valve plug and said closure, said resilient ring means constituting said means generating said springing force.
Claim 12
Dependent Claim
198 words
A multiway switch valve, comprising, A. a valve housing, B. a valve chamber formed in said valve housing and having A wall, C. a plurality of fluid-carrying housing channels formed in said valve housing, each said housing channel having a terminal opening merging into said valve chamber, D. a valve plug rotatably disposed in said valve chamber, said valve plug having a sealing face in the shape of an annular section of a spherical surface, E. a plurality of fluid-carrying plug channels formed in said valve plug, each said plug channel having a terminal opening on the surface of said plug, at least some of the last-named openings being disposed on said sealing face, F. an open annular collecting channel provided in a base wall of said valve chamber for gathering liquid leaking between said valve plug and the wall of said chamber, G. means for effecting a fluid tight engagement between at least some of said housing channel openings and said sealing face of said valve plug and H. means for rotating said valve plug into any one of a plurality of positions to interconnect selected ones of said housing channels by means of said plug channels.
