Abstract
Abstract Electromagnetic valve comprising a ball valve adapted to coact by magnetic attraction with the core of an electromagnet forming a passage for the fluid to be controlled and comprising a valve seat formed at the end of said passage, characterized in that said seat consists of an inner conduit of flexible material and of a rigid outer collar adapted to be secured to said core, said inner conduit being retained in said collar on the ball side by the engagement of registering shoulders, and adapted to undergo a certain elastic distortion when said ball is attracted to its seated position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
An electromagnetic valve for controlling the flow of a fluid comprising a. an electromagnet having a central core, said core having a passage therein for the flow of said fluid, b. a valve seat positioned within the core at one end of said electromagnet, said seat consisting of a rigid outer collar secured to the inner surface of said core and an inner conduit of flexible material, said outer collar and inner conduit being provided with registering shoulders for retaining said conduit within said collar, c. a ball-enclosing chamber secured to said one end of said electromagnet, and d. a magnetic ball located within said chamber and contacting the outer collar and inner conduit of said valve seat when said electromagnet is energized, the outer collar acting as an abutment to limit the movement of said ball and provide a minimum gap in the closed valve position, said inner conduit undergoing an elastic distortion when said ball is attracted to its seated position.
Claim 2
Dependent Claim
163 words
An electromagnetic valve for controlling the flow of a fluid comprising a. an electromagnet having a central core, said core having a passage therein for the flow of said fluid, b. a valve seat positioned within the core at one end of said electromagnet, said seat consisting of a rigid outer collar secured to the inner surface of said core and an inner conduit of flexible material, said outer collar and inner conduit being provided with registering shoulders for retaining said conduit within said collar, c. a ball-enclosing chamber secured to said one end of said electromagnet, and d. a magnetic ball located within said chamber and contacting the outer collar and inner conduit of said valve seat when said electromagnet is energized, the outer collar acting as an abutment to limit the movement of said ball and provide a minimum gap in the closed valve position, said inner conduit undergoing an elastic distortion when said ball is attracted to its seated position.
Claim 3
Dependent Claim
28 words
Electromagnetic valve according to claim 1 wherein the end face of said inner conduit, on the ball side, projects slightly from the adjacent end edge of said collar.
Claim 4
Dependent Claim
43 words
Electromagnetic valve according to claim 1 wherein said ball-enclosing chamber comprises two different bores, the bore having the smaller diameter being adjacent to said valve seat so as to permit the necessary cooperation between said ball and the inner conduit of flexible material.
Claim 5
Dependent Claim
33 words
Electromagnetic valve according to claim 1 wherein said inner conduit of flexible material provides a cylindrical fluid passage on the ball side and an opposite fluid passage tapering outwards on the core side.
Claim 6
Dependent Claim
29 words
Electromagnetic valve according to claim wherein the vertex angle of said tapered fluid passage is about 20* said tapered fluid passage beginning approximately in the middle of said conduit.
Claim 7
Dependent Claim
22 words
Electromagnetic valve according to claim 1 wherein said outer collar consists of nonmagnetic material and said ball consists entirely of magnetic material.
Claim 8
Dependent Claim
28 words
Electromagnetic valve according to claim 1 wherein said outer collar consists of magnetic material and said ball consists of magnetic material coated with a layer of nonmagnetic material.
