Abstract
A discharge valve assembly is provided for preventing reverse rotation of a scroll compressor. The discharge valve assembly includes a cup-shaped valve member slidably engaged with a central post of a retainer member. The cup-shaped valve member includes notches in communication between the central post of the retainer and the sidewalls of the cup-shaped valve member.
Claims22
A discharge valve for a scroll compressor, comprising:
- a valve seat surface facing downstream of a discharge passage of the scroll compressor;
- a valve member having a body portion for engaging said seat surface for closing said discharge passage, said valve member including a guide portion extending axially from said body portion;
- and
- a retainer slidably engaging with said guide portion of said valve member, said retainer including at least one passage in communication with a space between said valve member and said retainer.

A discharge valve for a scroll compressor, comprising:
- a valve seat surface disposed in a discharge passage of the scroll compressor, said valve seat surface facing downstream from the discharge passage;
- a valve member having a generally cup-shaped body with a cylindrical sidewall and a base portion enclosing a forward end of said cylindrical sidewall, said cylindrical sidewall including at least one vent formation in said cylindrical sidewall;
- and
- a retainer having a cylindrical outer sidewall and a retainer base portion disposed in a rearward end of said cylindrical outer sidewall, a central stem axially extending from said retainer base portion, said cylindrical sidewall of said valve member being slidably received on said central stem, said central stem including a through hole extending axially therethrough.
