Abstract
Abstract Disclosed is an electromagnetically operated force motor which positions a valve member with respect to a valve seat to open and close a valve, thereby controlling the flow of fluid through a chamber which is sealed with respect to the force motor. Various portions of the force motor are maintained in position by a mechanical bond which provides a fluidtight seal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
In a valve structure, a fluidtight seal between adjacent members comprising: a first metallic member having first and third continuous grooves formed therein; a second metallic member having second and fourth continuous grooves formed therein; said first and second grooves being positioned in aligned opposed relationship; said third and fourth grooves being positioned in aligned opposed relationship; said first and second members defining a continuous unobstructed opening therebetween extending from said grooves to a surface of one of said members; and first and second metallic insert means swaged into and filling said aligned first and second grooves, and said aligned third and fourth grooves respectively, and a portion of said continuous opening.
Claim 2
Dependent Claim
112 words
In a valve structure, a fluidtight seal between adjacent members comprising: a first metallic member having first and third continuous grooves formed therein; a second metallic member having second and fourth continuous grooves formed therein; said first and second grooves being positioned in aligned opposed relationship; said third and fourth grooves being positioned in aligned opposed relationship; said first and second members defining a continuous unobstructed opening therebetween extending from said grooves to a surface of one of said members; and first and second metallic insert means swaged into and filling said aligned first and second grooves, and said aligned third and fourth grooves respectively, and a portion of said continuous opening.
Claim 3
Dependent Claim
43 words
A fluidtight seal in a valve structure as defined in claim 1 wherein said metallic insert means includes a third insert sandwiched between said first and second inserts and being constructed of relatively hard material as compared to said first and second inserts.
Claim 4
Dependent Claim
89 words
at least one of said inlet and outlet ports including: a. an orifice in said body having an inwardly directed flange defining a continuous shoulder and an outwardly directed groove displaced longitudinally from said flange; b. an insert member defining an opening therethrough positioned within said orifice and defining an inwardly directed groove, said insert member seating against said shoulder whereby said grooves are in opposed aligned relationship; and c. a malleable metal filling said opposed grooves and providing a gastight seal between said body and said insert member;
Claim 5
Dependent Claim
89 words
at least one of said inlet and outlet ports including: a. an orifice in said body having an inwardly directed flange defining a continuous shoulder and an outwardly directed groove displaced longitudinally from said flange; b. an insert member defining an opening therethrough positioned within said orifice and defining an inwardly directed groove, said insert member seating against said shoulder whereby said grooves are in opposed aligned relationship; and c. a malleable metal filling said opposed grooves and providing a gastight seal between said body and said insert member;
Claim 6
Dependent Claim
30 words
said orifice in said body and the outer surface of said insert member defining an unobstructed tubular opening extending from said malleable metal to the outer surface of said body;
Claim 7
Dependent Claim
