    摘要： An engine-waste-heat utilization device includes a Rankine cycle with a heat exchanger that is configured to recover engine-waste-heat to refrigerant, an expander that is configured to generate power using the refrigerant coming out from the heat exchanger, a condenser that is configured to condense the refrigerant coming out from the expander and a refrigerant pump that is configured to supply the refrigerant coming out from the condenser to the heat exchanger by being driven by the expander, a power transmission mechanism (crank pulley, pump pulley, belt) that is configured to transmit surplus power to the engine when the expander has spare power even if the refrigerant pump is driven, a clutch that is configured to connect and disconnecting power transmission by the power transmission mechanism, and a case provided near a high-temperature part of the engine such that a shaft of the expander and that of the refrigerant pump are coaxially arranged, the clutch, the refrigerant pump and the expander are integrally housed in this order and the expander has a higher temperature than the clutch.

    摘要： A compressor capable of surely reducing, with an inexpensive structure, the possibility of occurrence of vibration and noise generated by the self-excited vibration of a suction valve when a flow is small, wherein an opening adjusting valve (40) installed in a refrigerant sucking flow passage (13c) leading to a cylinder (11a) is formed of an elastically deformable spiral member (41), and an interval between the spiral parts (41a) of the spiral member (41) is varied according to the flow of refrigerant to adjust the opening of the flow passage (13c), whereby the possibility of occurrence of the vibration and noise by the self-excited oscillation of the suction valve (14c) when the flow is small can be surely reduced, and the structure of the opening adjusting valve (40) can be simplified.
