Title:
VANE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2013/105147
Kind Code:
A1
Abstract:
Provided is a vane compressor in which wear of the tip portions of vanes is suppressed, bearing sliding loss is reduced since the rotation shaft can be supported at the minor diameter, and the precision of the outer diameter and center of rotation of the rotor section are improved. The distance (rv) between the outer circumferential side of vane aligners (5c, 5d) and a vane tip portion (5b) is set such that the equation rv=rc-ra-δ is satisfied, where the gap between the vane tip portion (5b) and a cylinder inner circumferential surface (1b) is δ, the radius of the cylinder inner circumferential surface (1b) is rc, and the radii of vane aligner bearing sections (2b, 3b) are ra. As a result, the vane tip portion (5b) of a first vane (5) rotates without contacting the cylinder inner circumferential surface (1b).
