Embodiment Construction

[0025] Piston compressors according to first to eighth embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] refer to figure 1, The piston compressor of the first embodiment is a fixed displacement swash plate compressor. The compressor includes a front cylinder 1 and a rear cylinder 3 . The front cylinder block 1 has a front axle hole 1A penetrating therethrough and a plurality of front cylinder bores 1B formed around the front axle hole 1A. Similarly, the rear block 3 has a rear axle hole 3A penetrating therethrough and a plurality of rear cylinder bores 3B formed around the rear axle hole 3A. The front cylinder block 1 and the rear cylinder block 3 are joined together such that the front axle bore 1A and the front cylinder bore 1B are aligned with their corresponding rear axle bore 3A and rear cylinder bore 3B, respectively. The front cylinder bore 1B and the rear cylinder bore 3B cooperate to form a plurality ...

Abstract

A piston compressor includes first and second cylinder blocks having an inlet port and a swash plate chamber, a drive shaft having first and second guide holes, and a swash plate having first and second supply ports. The swash plate chamber communicates with the inlet port and also with the first and second guide holes via the first and second supply ports, respectively. A distance from the inletport to the first supply port when the first supply port is moved closest to the inlet port is greater than a distance from the inlet port to the second supply port when the second supply port is moved closest to the inlet port, and the smallest flow passage area in the first supply port and the first guide hole is greater than the smallest flow passage area in the second supply port and the second guide hole.

Description

technical field [0001] The invention relates to a piston compressor. Background technique [0002] Japanese Utility Model Application Publication No. 63-174579 discloses a piston compressor comprising a pair of front and rear cylinders. The front block has a front axle hole at its center and a plurality of front cylinder bores formed around the front axle hole. Similarly, the rear block has a rear axle hole at its center and a plurality of rear cylinder bores formed around the rear axle hole. The front and rear blocks are joined together such that the front axle bore and front bore are aligned with the rear axle bore and rear bore, respectively. The front cylinder bore and the rear cylinder bore cooperate to form multiple pairs of front and rear cylinder bores. The front and rear blocks have a swash plate chamber between them. [0003] The piston compressor also includes a pair of front and rear casings. The front housing is coupled to the front cylinder block via a fro...
