Embodiment 1

[0023] like figure 1 Shown is a cross-sectional view of a conventional two-way swash plate type compressor used in a vehicle air conditioner, which has a pair of front cylinder block 12 and rear cylinder block 13, and bolts 16 fasten the front cylinder block 12 and the rear cylinder block 13 together to form Swashplate cavity 40 . The drive shaft 11 penetrates the swash plate 5 , the front thrust bearing 6A, and the rear thrust bearing 6B. The front end of the thrust bearing 6A is supported by the cylinder block 12 , and the rear end of the inference bearing 6B is supported by the rear cylinder block 13 . When the bolts 16 pass through the front cover 14 , the front cylinder block 12 , the rear cylinder block 13 and the rear cover 15 and tighten these parts, the front static surface of the rear end of the front cylinder block 12 and the rear static surface of the front end of the rear cylinder block 13 will The thrust bearing 6A, the rear thrust bearing 6B, and the swash pla...

Abstract

The invention provides a swash plate compressor and a piston thereof. The swash plate compressor is used for providing a lubricating oil channel between a sliding shoe and the piston, so that sufficient lubrication between the sliding shoe and the piston is achieved. The piston of the swash plate compressor comprises a piston seat and a piston head, and a spherical socket used for installing the sliding shoe is formed in the piston seat. The piston is characterized in that the piston head is provided with the lubricating oil channel penetrating through the end face of the piston head to the bottom of the spherical socket.

Description

technical field [0001] The present invention relates to a swash plate type compressor and its piston, in particular to a lubricating oil supply structure in the swash plate type compressor and its piston. Background technique [0002] A part of the lubricating oil in the swash plate cavity of the existing swash plate compressor is deposited on the bottom of the swash plate cavity, and the rest is dispersed in the entire space of the swash plate cavity, and is mixed with the refrigerant gas stirred by the compressor movement mechanism to form oil mist . The oil at the bottom is not easy to reach each friction surface, and the oil mist in the swash plate cavity moves irregularly, only a small part can penetrate into the friction surface, and the lubrication effect is not good. [0003] The friction surface between the shoe and the ball crater on the piston is located in the swash plate cavity, and the two are roughly in spherical contact, which is a position with insufficient...
