<P>PROBLEM TO BE SOLVED: To provide a variable displacement swash plate type compressor that limits the amount of a blow-by gas flowing in a crank chamber without increasing the number of components. <P>SOLUTION: In this variable displacement swash plate type compressor C, pistons 30 are housed in a plurality of cylinder bores 11a formed in a cylinder block 11, and a swash plate 22 rotating integrally with a drive shaft 16 is housed in a crank chamber 15. The piston 30 is moored to the swash plate 22, and a compression chamber 24 is formed in the cylinder bore 11a by the piston 30. A first control valve CV1 is arranged in an air supply passage 39. An introduction groove 11b for a blow-by gas is formed on a side closer to a bottom dead point of the piston 30 than a top dead point position P1 thereof on a slide surface S of the cylinder bore 11a, and an introduction passage 17 from the introduction groove 11b to an intake chamber 31 is formed in the cylinder block 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
