<p>PURPOSE:To improve the responsiveness of capacity control by arranging an intake control valve on an intake passage between a discharge chamber and a crank chamber, and arranging bleed control valves responding to the crank chamber pressure and the discharge chamber pressure with bleed passages between an intake chamber and the crank chamber in parallel respectively. CONSTITUTION:An intake control valve 20 is arranged between a discharge chamber 4 and a crank chamber 5, and it is communicated with the discharge chamber 4 and the crank chamber 5 via intake passages 30a, 30b. The intake control valve 20 opens or closes the intake passages 30a, 30b in response to the pressure of an intake chamber 3. Bleed control valves 40, 60 are provided between an intake chamber 3 and the crank chamber 5, and they are communicated with the intake chamber 3 and the crank chamber 5 in parallel via bleed passages 41a-41c. The bleed control valves 40, 60 adjust the flow quantities of the bleed passages 41a-41c in response to the pressure of the crank chamber 5 and the pressure of the discharge chamber 4 respectively.</p> |
