<p>PURPOSE:To reduce the load on starting a compressor and permit the smooth start by preventing the hydraulic pressure in a pressure chamber from being introduced into a control pressure chamber before a piston is shifted by the hydraulic pressure supplied from an oil pump. CONSTITUTION:A piston 220 for shifting the clutch plates 320 and 330 of a connecting mechanism and a bypass valve 540 for opening and closing the variable capacity type bypass port 520 of a compressor 600 are controlled by the hydraulic pressure supplied from a same oil pump. In other words, the hydraulic pressure supplied from an oil pump 201 is introduced into a pressure chamber 225 on the back surface of the piston through an introduced oil passage 228, and introduced from the pressure chamber 225 into a control pressure chamber 550 on the back surface of a bypass through a signal passage 351. With such constitution, the load on starting can be reduced, and the smooth start of the compressor is permitted.</p> |
