<p>PURPOSE:To suppress the hunting phenomenon by controlling the internal pressure in the evaporator of an air conditioner or the air temperature within the two preset limits. CONSTITUTION:A discharge volume control means 8 has an external operation control device 9 operated by the external signal input when the heat load to an evaporator of an air conditioner is the preset value or more to communicate a crank chamber 2 and a suction chamber 15 and a pressure operation control device 10 communicating and controlling the crank chamber 2 and the suction chamber 15 to keep the pressure in the crank chamber 2 nearly constant. The pressure operation control device 10 has a bypass hole 101 and the bellows 103, the bellows 103 is expanded and a needle valve 103a closes an opening section 101a when the pressure in the crank chamber 2 becomes a fixed value or lower.</p> |
