(EN) Three-bore variable displacement compressor with a swash plate having an adjustable incline
要約
(EN)

Variable displacement compressor, with center bore 101b in a center part of cylinder block 101, includes: first bore 101b1 supporting plain bearing 131 of drive shaft 110; second bore 101b2 with a peripheral wall radially outside of first bore 101b1; and third bore 101b3 connected to a crank chamber and radially outside of a first bore 101b1. A pressure supply path 145 for flowing a part of a discharge refrigerant from a discharge chamber to the crank chamber includes: second bore 101b2; a first path 145a communicating second bore 101b2 with the discharge chamber; a second path 145b that communicates with second bore 101b2, and axially extends from one end surface of drive shaft 110 toward the inside of drive shaft 110; and a third path 145c substantially orthogonal to second path 145b and opens to an outer peripheral surface of drive shaft 110, and communicates with the crank chamber.
