Title:
GAS COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2018/179701
Kind Code:
A1
Abstract:
Provided is a gas compressor configured so as to prevent or suppress excessive compression and to prevent a vane from becoming unfollowable. In this compressor (100), the shape of the cross-sectional contour of the inner peripheral surface (41) of a cylinder (40) is configured such that: (1) the shape has closest sections (portions (a)) closest to the outer peripheral surface (51) of a rotor (50), and also has farthest sections (portions (b1)) farthest from the outer peripheral surface (51); (2) the farthest sections are formed offset toward the upstream side in the rotational direction (R) of the rotor (50) so that a compression stroke and a discharge stroke are longer than a suction stroke; and (3) angular range portions (d, c) extending from the closest sections to the farthest sections on the downstream side in the rotational direction (R) include elliptically shaped arcs (first curved lines) with which the front end (58a) of a vane (58) is continuously in contact, and also include circular arcs (second curved lines), the distance (r) of which from a center axis (C) varies to smoothly connect ends of the elliptically shaped arcs and the farthest sections.
