ABSTRACT:
A compressor comprises a cylinder assembly forming a compression space. A compressing member is movable disposed in the compression space for compressing fluid therein. A discharge port communicates with the compression space for discharging compressed fluid. A valve is mounted on the cylinder assembly for sliding movement across the discharge port between a first position blocking the discharge port, and a second position unblocking the discharge port. A valve mover in the form of a plate spring is connected to the valve and communicates with pressure in the compression space. In response to a pressure build-up in the compression space, the plate spring is elastically deformed to slide the valve from the first position to the second position for unblocking the discharge port.
