Claims

[Scope of utility model registration request]

a drive shaft having a plurality of eccentric parts; a plurality of cylinders forming compression chambers concentric with the drive shaft to accommodate the eccentric parts; and an inner periphery of the cylinder driven by the eccentric parts of the drive shaft. a rolling piston that rolls along a surface, a vane that is pressed by an elastic member on the outer periphery of each rolling piston and divides the compression chamber into a high pressure chamber and a low pressure chamber, the cylinder at each eccentric portion, and the rolling piston. and an intermediate partition plate made of a single plate for arranging the compressor element made of the vane independently in the axial direction of the drive shaft, the eccentric part of the drive shaft being inserted into the drive shaft by a spline mechanism. A multi-cylinder rotary compressor characterized in that it is installed so that it can be removed.
