Abstract:
PROBLEM TO BE SOLVED: To provide a four-way valve that reduces heat loss and also mounting space at low cost, and to provide a heat pump device with the same.SOLUTION: A high-pressure four-way valve 10 includes a cylindrical body 12 having a high-voltage entrance 14, a valve seat having exits 18 at two positions, and a slide valve which switches a state of communication between the high-voltage entrance 14 and the exits. A low-pressure three-way valve 30 includes a cylindrical body 32, a valve seat which has entrances 36, 38 at two positions and also has a low-pressure exit 34 between those entrances, and a slide valve which switches a state of communication between the low-pressure exit 34 and the entrances. One exit 18 of the high-pressure four-way valve 10 and one entrance 38 of the low-pressure four-way valve 30 are communicated with each other, the other exit of the high-pressure four-way valve 10 and the other entrance 36 of the low-pressure four-way valve 30 are communicated with each other, and the bodies 12, 32 are arranged to be close each other so that their cylinder-axis directions are substantially in parallel and both ends are substantially flush with each other.
