<p>PURPOSE:To control the correction of a pressure loss simply and accurately by providing a closing valve for opening/closing a connecting passage between an intake chamber and a crankcase and a control means for giving a load generated by the pressure of a discharge chamber to the closing valve to displace an opening/closing operating point. CONSTITUTION:A main shaft 2 passes through a compressor casing 1 and a rotor 5 is installed on the main shaft 2. A swash plate 6 is installed on the rotor 5 via a hinge mechanism 51 while the swash plate 6 is linked to a piston 10 provided in a cylinder 9 via an oscillating board 7 and a piston rod 8. In this structure, bellows 21 are provided inside the valve chamber member 19a of a control device 19 and the hole 20a of a base sent 20 is opened/closed by means of a valve body 21a provided on the end thereof. A valve cylinder 100 which is connected to a discharge chamber 15 is provided on the side of the base seat 20 and an actuating rod 101 is inserted into the valve cylinder 100.</p> |
