Claims

[Scope of utility model registration request]

a front plate that rotatably supports the rotor shaft and forms a back pressure chamber between it and a groove formed in the rotor;
A front housing having a suction hole and defining a suction chamber together with the front plate, and a mechanical seal chamber interposed between the front housing and the rotor shaft and defining a mechanical seal chamber on the front plate side together with the front housing and the rotor shaft. an annular cover plate comprising: 7 a mechanical seal provided in the mechanical seal chamber that slides in contact with the cover plate and has an O ring fitted on the radially inner side to seal the mechanical seal chamber from outside air; and a mechanical seal fixed to the rotor shaft knee. A spring is provided between the retainer and the mechanical seal and presses the mechanical seal toward the cover plate, and a spring is provided between the front plate and the rotor shaft and connects the mechanical seal chamber and the back pressure chamber. A vane type rotary compressor, comprising: a shaft seal for blocking the mechanical seal; and the shaft seal is interposed between the mechanical seal and the spring.
