Abstract

PURPOSE:To always form a good lubricating film, by arranging a back pressure feed oil hole to a rear side plate, communicating a feed oil passage to the rear part of a vane from said back pressure feed oil hole, interposing a thrust bearing in said feed oil passage and utilizing vane back pressure feed oil directly to lubrication for said thrust bearing. CONSTITUTION:Pressure oil, reaching a thrust bearing box 26 arranged between the rear side slide surface of a rotor 8 and rear side plate 6, is fed and flow divided to each slide part, containing a rear side thrust needle bearing 19, to perform lubricating action. The pressure oil partially passes through a gap, constituted between a rear end part 16 of rear side thrust race and rear side plate 5, to flow out to a rear side radial needle bearing 7, while passes through a gap, constituted between a rear side thrust race 18 and the rear side thrust needle bearing 19 and the rear side plate 6, to lubricate between the rear side thrust race 19 and rear side thrust needle bearing 19 and also lubricate the rear side slide surface of the rotor 8.
