Variable displacement swash plate compressor

摘要

A variable displacement swash plate compressor that includes a cylinder bore, a swash plate chamber, a swash plate, and a double head piston, which defines first and second compression chambers in the cylinder bore. First and second suction chambers are in communication with the first and second compression chambers, respectively. The displacement of the top dead center of the piston in the first compression chamber is greater than the displacement of the top dead center of the piston in the second compression chamber. A first suction passage extends from a suction port to the first suction chamber without passing through the second suction chamber and the swash plate chamber. A second suction passage extends from the first suction chamber to the second suction chamber.
