Abstract

A novel compressor valve is disclosed. Generally, the valve includes a valve guard containing a flange portion formed thereon. The valve will contain a valve seat adapted to engage the valve guard. The valve contains a first sealing plate and a second sealing plate received within the valve. The first and second sealing plate will cooperate in order to allow flow in only one direction. In the preferred embodiment, the compressor valve further comprises a biasing member adapted for biasing the first sealing plate with the second sealing plate. The first and second sealing plates are removable and may be replaced as a unit.

Claims

1. A valve comprising:

a valve guard containing a flange portion formed thereon with first means for selective passage of a medium;

a valve seat means engaging said valve guard containing second means for selective passage of a medium;

a first sealing plate having a first sealing face thereon, said first sealing plate being, received within said valve seat, containing third means for selective passage of a medium;

a second sealing plate having a second sealing face thereon, said second sealing plate being operatively associated with said first sealing plate and received within said valve guard containing fourth means for selective passage of a medium, and wherein said first sealing face and said second sealing face cooperate to form a seal to a flow;

spring means for biasing said first sealing plate with said second sealing plate so that said first sealing plate and said second sealing plate form a cartridge, and wherein said spring means contains a first end and a second end, with said first end being attached to said first sealing plate and said second end being attached to said second sealing plate;

means for attaching said valve guard with said valve seat;

and wherein said flange engages said first sealing plate so that said first sealing plate is held in a stationary position relative to said valve guard and said valve seat, and said second sealing plate is movable relative to said valve guard and said valve seat;

and wherein said first and second sealing plate contains an aligned aperture bored axially through said second sealing plate, and said second sealing plate contains an aperture bored radially relative to said axial bore, and wherein said spring means contains;

a spring having a first end and a second end, with said spring being disposed within said axial bore, with said spring having said first end being attached to said first sealing plate;

a shaft disposed within said radial bore;

and wherein the second end of said spring is attached with said shaft.

2. A compressor valve for regulating the flow of a medium comprising:

a guard member with a shoulder;

a seat member having a recess therein;

a first valve element having a first sealing surface and contained within said seat member;

a second valve element having a second sealing surface and configured to sealingly engage said first sealing surface of said first valve element;

means for attaching said guard member with said seat member;

biasing means for biasing said first valve element with said second valve element so that said first valve element and said second valve element form a cartridge, and wherein said biasing means has a first end and a second end, with said first end being attached to said first valve element and said second end being attached to said second valve element;

and wherein said shoulder of said guard member engages said first valve element so that said first valve element is held in a stationary position relative to said valve guard and said valve seat, and said second valve element is movable relative to said guard member and said seat member;

exhaust port means, disposed within said guard member, for allowing passage of the medium through said guard member;

intake port means, disposed within said seat member, for allowing passage of the medium through said seat member; and

,

first flow port means, disposed within said first valve element, for allowing passage of the medium through said seat member;

and second flow port means, disposed on said second valve element, for allowing passage of the medium, and wherein said first flow port and said second flow port are arranged so that as said first valve element is adjacent said second valve element, no passage of said medium is allowed;

and wherein said first sealing plate contains an axial bore therethrough and said second sealing plate contains a second axial bore aligned with said axial bore of said first sealing plate, and said second sealing plate further contains a radial bore formed radially relative to said second axial bore, and wherein said spring means contains;

a spring having a first end and a second end, with said spring being disposed within the axial bore of said first and second sealing plate, with said spring having said first send end being attached to said first sealing plate;

a shaft disposed within said radial bore;

and wherein the second end of said spring is attached with said shaft.
