Abstract

The present invention aims at avoiding the friction between the valve spring and the exhaust cover to cause damage, and the exhaust valve assembly includes exhaust cover, exhaust valve and valve spring. The exhaust cover is installed to the end of the cylinder with linearly reciprocating piston, the exhaust valve is set between the cylinder and the exhaust cover, and the valve spring is set between the exhaust valve and the exhaust cover to support the exhaust valve elastically. The present invention features the cover protecting part, which is made of lubricating material and is set in thecontact part between the exhaust cover and the valve spring to avoid the wear of the exhaust cover and the valve spring.

Description

technical field [0001] The invention relates to a discharge valve assembly in the field of valves, in particular to a discharge valve assembly capable of preventing wear caused by mutual friction between a valve spring and a discharge cover. Background technique [0002] In the general valve assembly, the valve assembly is discharged axially, and the piston combined with the rotor of the motor performs linear reciprocating motion in the cylinder to inhale the gas, compress and discharge the gas in the direction of the piston's movement. When the piston reciprocates, the opening and closing speed of the discharge valve is closely related to the performance of the entire discharge valve assembly. [0003] figure 1 and figure 2 It is a cross-sectional view and an exploded view of an axial discharge valve assembly (hereinafter simply referred to as a discharge valve assembly). [0004] As shown in the figure, the discharge valve assembly in the prior art includes the followi...
