Title:
ROTARY CYLINDER TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/187816
Kind Code:
A1
Abstract:
The rotary cylinder type compressor (1) comprises: a cylinder (21) disposed inside a housing (10) in a rotatable manner; and a cylindrical rotor (22a, 22b) disposed inside the cylinder and rotating about an eccentric axis with respect to a rotation center axis of the cylinder. In addition, the rotary cylinder type compressor (1) comprises a partition member (23a, 23b) for partitioning a working chamber, which is formed between the outer peripheral surface (225a, 225b) of the rotor and the inner peripheral surface (21a) of the cylinder, into a suction space into which a fluid is sucked and a compression space for compressing the fluid. At least one rotor is disposed inside the cylinder. The rotor and the cylinder are constructed such that contact stress acting on a proximate part, of the outer peripheral surface (225a, 225b) of the rotor and the inner peripheral surface (21a) of the cylinder, increases when the pressure of the fluid in the compression space reaches a predetermined reference pressure or higher than when the pressure of the fluid is lower than the reference pressure.
