<p>An object of the invention is to provide a swash plate compressor capable of realizing an excellent sliding characteristic when a drive shaft is rotated at high speed, and a high refrigerating capacity when the drive shaft is rotated at low speed. The swash plate compressor according to the invention comprises an release passage 62 for communication between a crank chamber 24 and a suction chamber 20. The release passage 62 includes a first passage 12b, 12c, 62, 66, 68, 18a communicated to an oil rich region, in which lubricating oil is large in quantity, in the crank chamber 24, and a second passage 64, 68, 18a communicated to an oil poor region, in which lubricating oil is small in quantity, in the crank chamber 24. Also, the swash plate compressor comprises an valve mechanism 70 that increases an opening ratio of the first passage 12b, 12c, 62, 66, 68, 18a with respect to the release passage 62, as a rotational speed of a drive shaft 16 increases, and increases an opening ratio of the second passage 64, 68, 18a with respect to the release passage 62, as the rotational speed of the drive shaft 16 decreases.</p> |
