Abstract

A rotary compression mechanism is provided with a rotor which can rotate about the axis of a shaft mounted to a casing, a cylinder which can rotate about a rotation center eccentric from the shaft, and a drive plate which is installed so as to be capable of swinging relative to one of the cylinder and the rotor and to be capable of sliding relative to the other of the cylinder and the rotor and which rotationally connects the cylinder and the rotor. Spaces which are separated from each other by both a partition point and the drive plate and which are located between the inner surface of the cylinder and the outer periphery of the rotor are operating chambers for performing compression or suction.

Dependent claims

A rotary compressor which is provided with a rotor which can rotate about an axial center of a shaft which is attached to a casing, a cylinder which can rotate about a center of rotation which is eccentric from said shaft, and a drive plate which can swing with respect to either said cylinder or said rotor and can slide with respect to the other and which connects said cylinder and said rotor to be able to rotate, and a side plate which forms a side part of said drive cylinder, wherein,

an inner surface of said cylinder and an outer circumference of said rotor are made to contact at a partition point by making the center of rotation of said cylinder eccentric from the axial center of said shaft, and
the space between an inner surface of said cylinder and an outer circumference of said rotor, which is partitioned off by said partition point and said drive plate, forms working chambers for compression or suction.
a suction passage is provided at said shaft and said rotor for suction into the working chamber which performs suction and a discharge valve part is provided for discharge at a side plate which forms a side part of said cylinder.

Dependencies are inferred from the claim text.
