A plurality of cooling passages are drilled radially from the outer periphery of each of the two valve seats toward the center, and the cooling passages drilled in one valve seat are connected to a center bolt that presses these two valve seats together. A valve mechanism for a gas compressor, in which the cooling passage is bored into an outer circumferential space and is made to communicate with the cooling passage, which is bored in the other valve seat so as to surround a discharge plate valve.

Claims

[Scope of Claim for Utility Model Registration] A valve device for a small air-cooled piston compressor comprising an automatic valve equipped with a plate valve, a spring, and a gas passage for suction and discharge on two valve seats, comprising: A compact type, characterized in that it passes through a cooling passage through which a cooling liquid passes, and compresses a working fluid having a large specific heat ratio with the cooling liquid so as to cool at least the discharge plate valve and the spring. Cooling device for valves for air-cooled piston compressors. The automatic valve is an annular valve, and the cooling passage is a radial small hole drilled from the outer periphery of the valve seat to the outer circumferential space of the central bolt that presses the two valve seats. A cooling device for a compressor valve as described. A cooling device for a compressor valve according to claim 1, wherein gas sealing O-rings are provided on the center bolt above and below the outer peripheral space of the center bolt. A cooling device for a valve for a compressor according to claim 1, wherein the cooling fluid is lubricating oil cooled by an oil cooler.
