Valve assembly of compressor

A valve assembly of a compressor comprises the following components: a valve support plate provided with three suction holes for sucking gas to a cylinder interior and discharging holes for discharging compressed gas from the cylinder interior; a suction valve combined with the valve support plate for opening and closing the suction hole; a discharging valve combined with the valve support plate for opening and closing the discharging holes, wherein the suction hole is one and the discharging holes are two, the suction valve for opening and closing one suction hole is one and the discharging valves for opening and closing the two discharging holes is one. In the valve assembly of the compressor in the invention, when the gas is sucked in the cylinder, the suction flow drag of the gas is reduced, and the gas suction efficiency is improved, when the compressed gas in the cylinder is discharged out of the cylinder, then the discharging flow drag of the compressed gas is reduced, and the compression loss is reduc
