Claims

[Claims for Utility Model Registration] 1. A cylinder body 9 is fixed to the casing 1, and a drive shaft 6 is pivotally supported on the cylinder body. A cylinder 9a is bored in each divided position in the axial direction of the cylinder, a piston 10 is fitted into the cylinder so as to be able to slide in the axial direction, and the drive shaft is provided with a cylinder 9a. A swash plate 7 is fitted, and the piston is configured to reciprocate within the cylinder in the axial direction when the drive shaft rotates by interlocking with the swash plate, and each of the cylinders has an opening. The axial end surface 9b of the cylinder body has a uniform plane, and a flat half plate 5 is interposed between the end surface and the side plate 3, and the drive shaft is enclosed in the side plate. A mechanical seal 6a is provided in a portion of the side plate that presses the half plate, and a low pressure chamber 3d is provided in a portion of the side plate that faces the end surface 3b that presses the half plate and surrounds the outer periphery of the mechanical seal in the circumferential direction. A reinforcing material 3a fixed to the side plate is wrapped around the outer circumference of the mechanical seal in the low pressure chamber, and the reinforcing material has a notch 3g that communicates between the low pressure chamber and the mechanical seal. A swash plate type compressor, wherein a surface of the reinforcing member that presses the half plate is in the same plane as the end surface of the side plate. 2 The position of the notch 3g in the reinforcing material 3a is located in the low pressure chamber 3.
The swash plate type compressor according to claim 1, which is configured to face the direction in which the refrigerant flows as shown in FIG.
