<p>PURPOSE:To enhance the extent of responsiveness, by installing a pressure controller between an evaporator outlet and a compressor inlet as well as installing a flow passage interconnecting an upstream side flow passage of the pressure controller to a crank chamber. CONSTITUTION:A refrigeration system consists of a compressor 1, a condenser 2, a receiver 3, an expansion device and an evaporator 5. In space between an outlet of the evaporator 5 and the compressor 1, there are provided with a pressure controller 6 and a passage 7 interconnecting an upstream of this pressure controller 6 to a compressor crank chamber. Therefore, a swash plate tilting angle is directly controllable without controlling pressure in the crank chamber large in capacity, so that such volume control that is speedily followed to a revolving speed is performable.</p> |
