Abstract
A compressor check valve having a valve bolt and a valve bolt cover for noise reduction and mitigation of impact from a valve bolt on the valve bolt cover. A bolt insertion hole is provided in the cover to receive the valve bolt. A pressure conduction hole penetrating from the side of the valve bolt insertion hole of the cover through the exterior of the cover is provided on the cover to connect the high pressure chamber through the valve bolt insertion hole. A buffer section is formed on a top of the valve bolt insertion hole so that the valve bolt is forced by a high pressure coolant to move above and block the pressure conduction hole, the buffer section contains high pressure coolant prevented from being discharged through the pressure conduction hole to create a buffer action when the valve bolt moves upward so as to avoid direct impact against the valve bolt cover.
