Claims

[Scope of utility model registration request]

A plurality of sets of cylinder bores are bored parallel to the rotating shaft, facing each other on the front side and the rear side so as to form a front and rear pair with a swash plate chamber in between, and the swash plate chamber has an axis mounted on the rotating shaft. The swash plate is provided with a swash plate that can freely swing and rotate, and the periphery of the swash plate has a flat part and a spherical part, and the flat part of the shoe, which is formed into a substantially hemispherical shape, slides into contact with the swash plate. A piston is inserted into the piston so that it can freely reciprocate, and the mooring portion of the double-headed piston is recessed with a pair of front and rear spherical receiving portions facing each other, and the spherical portion of the shoe is moored to the spherical receiving portion. A lubrication mechanism for a double-headed piston in a swash plate compressor, characterized in that a thin wall portion is provided at the rear of the spherical receiving portion of the mooring portion to face the rotating direction of the swash plate.
