Title:
INTEGRATION VALVE AND DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/029421
Kind Code:
A1
Abstract:
 A fixed throttle (17), a liquid-phase-side valve body (162), a gas-phase-side valve body (161), and other elements are housed and integrated in a body (140) of an integration valve (14), and the valve bodies (161, 162) are displaced by a single driving device (18). The driving device (18) is configured so as to be capable of switching between a first mode in which a gas phase coolant channel (141f) is fully closed and a liquid phase coolant channel (142c) is fully open, a second mode in which the liquid phase coolant channel (142c) is fully closed and the gas phase coolant channel (141f) is fully open, and a third mode in which the liquid phase coolant channel (142c) is fully closed and the gas phase coolant channel (141f) is fully closed or slightly open. When a liquid entry condition in which a liquid phase coolant enters an intermediate-pressure coolant channel (15) is satisfied, a driving system switches the operation mode of the integration valve (14) to the third mode. Therefore, it is possible to simplify the cycle configuration of a heat pump cycle while inhibiting the liquid phase coolant from entering a compressor through the intermediate-pressure coolant channel (15).
