可変容量圧縮機。[Claims for Utility Model Registration] With the front and rear housings connected to both front and rear ends of a pair of opposed cylinder blocks, the cylinder blocks and both housings are tightened and fixed with bolts, and a swash plate chamber and a swash plate chamber are provided in the cylinder blocks. Cylinder bores are formed opposite to the front and rear sides of the swash plate chamber, and a double-headed piston is accommodated in the cylinder bores so as to be able to reciprocate, and is supported by a cylinder block so as to pass through the swash plate chamber. A swash plate located in the swash plate chamber and engaged with the double-headed piston is supported on the rotating shaft so that it cannot rotate relative to the swash plate and can swing back and forth around its peripheral edge, and the center of the swash plate is positioned closer to the rear cylinder bore. At the same time, the reciprocating movement area of the double-headed piston is set on the rotation area of the oscillation center due to the rotation of the rotating shaft, and the displacement can be adjusted by changing the piston stroke by changing the inclination of the swash plate. In the plate type variable capacity compressor, a bulge is formed on the inner surface of the peripheral wall of the cylinder block at a position where the bolt for tightening and fixing the housings and the cylinder block is arranged, and a bolt insertion hole is formed in the bulge. Swash plate type variable capacity compressor.
