Seal mechanism in compressor
First Claim
1. A compressor for compressing gas, comprising:
- a housing having a high-pressure region and a low-pressure region;
a rotary shaft rotatably supported by the housing;
a compression unit provided in the housing, the compression unit being actuated by the rotation of the rotary shaft to perform the gas compression;
a seal member having an annular and plate-like shape and provided in the housing for preventing the gas from leaking from the high-pressure region to the low-pressure region via a gap between the rotary shaft and the housing, pressure of the gas in the high-pressure region being applied to the seal member thereby generating a seal function, the seal member being fixed to one of the housing and the rotary shaft and in contact with an edge that is formed in the other of the housing and the rotary shaft and connects a first surface facing the high-pressure region and a circumferential surface coaxial with the rotary shaft in the other of the housing and the rotary shaft.

Abstract
A compressor includes a housing having a high-pressure region and a low-pressure region, a rotary shaft, a compression unit, and a seal member. The seal member has an annular and plate-like shape and is provided in the housing for preventing gas from leaking from the high-pressure region to the low-pressure region via a gap between the rotary shaft and the housing. Pressure of the gas in the high-pressure region is applied to the seal member thereby generating a seal function. The seal member is fixed to one of the housing and the rotary shaft and in contact with an edge that is formed in the other of the housing and the rotary shaft and connects a first-surface facing the high-pressure region and a circumferential surface coaxial with the rotary shaft in the other of the housing and the rotary shaft.
