Abstract:
Provided is a variable capacity compressor having a simple construction and for which the layout of a valve device is simple. This variable capacity compressor includes: a control valve 300 provided in a pressure supply passage connecting a discharge chamber 142 and a crank chamber 140; a changeover valve 350 arranged on the lower side, in the gravity direction, of the axial line of a drive shaft 110, and having a connecting part that is provided on the crank chamber 140 side of the control valve 300 in the pressure supply passage and that communicates with an intake chamber; and a constriction passage 320 connecting the intake chamber 141 and the pressure supply passage 145a between the control valve 300 and the changeover valve 350. When the control valve 300 has closed the pressure supply passage the changeover valve 350 shuts off the connection between the pressure supply passage 145a between the control valve 300 and the changeover valve 350 and the pressure supply passage 145b between the changeover valve 350 and the crank chamber 140, and connects the intake chamber 141 and the pressure supply passage 145b between the changeover valve 350 and the crank chamber 140 by means of the aforementioned connecting part.
