Abstract
A discharge valve assembly for use in a fluid displacement apparatus having a suction chamber and a compression chamber on one side of a valve plate, a discharge chamber on the other side of said valve plate, and a passage which is formed in the valve plate extending between said compression chamber and the discharge chamber and has an open end through which discharge fluid flows. The discharge valve assembly comprises an elastic valve member disposed on the valve plate. One end of the valve member is secured to the valve plate. The elastic valve member is capable of bending to open and close the passage. A stabilizing device is disposed on the elastic valve member for stabilizing movement of the elastic valve member. Thereby, a valved discharge mechanism, in a fluid displacement apparatus for use in an automobile air conditioning system, can effectively reduce the vibration caused by a discharge valve assembly, reduce the propagation of noise to a passenger compartment of a vehicle, and prolong the life of the valve member.
