Abstract
A compressor assembly includes a shell which defines a discharge chamber. A discharge valve assembly is attached to the shell in communication with the discharge chamber. The discharge valve assembly includes a stamped or coined valve seat, a drawn tubular element and a stamped valve member. The stamping, drawing and coining operations used to manufacture the discharge valve assembly significantly reduce the manufacturing costs for the discharge valve assembly.
Claims5
A compressor assembly comprising:
- a shell defining a discharge chamber;
- a compressor disposed within said shell, said compressor compressing a fluid from a suction pressure to a discharge pressure, fluid at said discharge pressure being directed to said discharge chamber;
- a discharge valve assembly attached to said shell in communication with said discharge chamber, said discharge valve assembly comprising:
- a tubular member secured to said shell;
- a valve seat secured to said tubular member;
- a stop secured to said shell, said stop and said valve seat defining a valve chamber;
- and
- a valve member disposed in said valve chamber, said valve member being movable between a closed position where said valve member abuts said valve seat and an open position where said valve member abuts said stop;
- wherein said tubular member is secured to an outside surface of said shell, said tubular member providing fluid flow between said discharge chamber and an environment outside said shell.

- and
- a valve member disposed in said valve chamber, said valve member being movable between a closed position where said valve member abuts said valve seat and an open position where said valve member abuts said stop;
- wherein said tubular member comprises:
- a tubular fitting secured to an outside surface of said shell, said tubular fitting providing fluid flow between said discharge chamber and an environment outside said shell;
- and
- a valve body disposed between said tubular fitting and said shell, said valve seat being secured to said valve body.
