Abstract

A compressor discharges compressed gas via a discharge hole opened and closed by a valve assembly. The valve assembly comprises a discharge valve and a valve stopper. One end of the discharge valve is fixed and pressed towards a position for closing the discharge hole. The discharge valve is elastic bended by the function of the compressed gas until striking on the valve stopper. The valve stopper contains a groove opening towards the discharge valve. While the valve is open, the groove is filled with gas, thus shock generated when a discharge valve hits a valve stopper is reduced, and the discharge valve is subsequently closed.

When opening outlet valve 41 so as to allow the refrigerant that compressed by the time, outlet valve 41 is dash valve baffle plate 42 just.Outlet valve produces this impact regularly, thereby has constituted the main noise source of compressor.
Equally, when outlet valve 41 dash valve baffle plates 42, outlet valve 41 is adjacent to the lower surface of valve guard 42.Therefore, when squeeze operation is finished, when outlet valve 41 was closed owing to the annular space of column 33 and the pressure reduction between the exhaust cavity 10a, the upper and lower sides of outlet valve 41 did not almost have pressure reduction.This shows that outlet valve 41 can break away from valve guard 42 at leisure.As a result, the gaseous refrigerant of some discharge flow back in the annular space of column 33, causes the serious decline of compressor efficiency.
An object of the present invention is to provide a kind of exhaust valve component, when outlet valve dash valve baffle plate, can reduce impact and the noise that is produced.
Another object of the present invention provides a kind of exhaust valve component, prevents backflowing of refrigerant by making outlet valve separate with valve guard very soon and to close floss hole, thereby makes compressor have good performance.
Can realize above-mentioned purpose according to compressor exhaust valve component of the present invention, this exhaust valve part comprises outlet valve and baffle means, and outlet valve has a fixed end and a free end and is used to open and close relief opening, and baffle plate is used to block the opening movement of outlet valve.There is one on the baffle means to the open air storing duct of outlet valve.Baffle means preferably includes a spigot baffle and a cushioning fender, and wherein spigot baffle is used to limit the distance that the outlet valve free end moves upward, and cushioning fender is placed in the place, bottom surface of spigot baffle and air storing duct is arranged.
According to the present invention, when outlet valve was opened owing to the pressure of compression refrigerant, the compression refrigerant in the air storing duct played shock absorbing and noise, prevented to take place when outlet valve damping of shocks baffle plate impact and noise etc.
And, when squeeze operation finishes, when outlet valve is closed because of the pressure reduction between exhaust cavity and the column annular space, because the pressure of refrigerant makes outlet valve quick closedown relief opening in the air storing duct of cushioning fender.
Therefore, the refrigerant annular space of column that can not backflow.
