Abstract:
Valve mechanisms (14a, 14b, 63a, 63b, 90) have: valve bodies (80, 95); a first flow path (81) formed at a position facing the tips (80a, 95b) of the valve bodies (80, 95); a drive unit (85) that moves the valve bodies (80, 95) between a first position at which the tips (80a, 95b) of the valve bodies (80, 95) close the first flow path (81) and a second position at which the tips (80a, 95b) of the valve body (80) open the first flow path (81); and a second flow path (82) that connects to the first flow path (81) when the valve body (80) is at the second position. High-pressure flow paths (I1, I2, O2, O3, 48) are configured such that high-pressure refrigerant always flows, in order, through the second flow path (82) then the first flow path (81), in the valve mechanisms (14a, 14b, 63a, 63b, 90).
