Abstract

PROBLEM TO BE SOLVED: To provide a four-way valve, which facilitates the assembling work when a motor in a driving part consisting of motors, etc., is assembled with a motor cover, which reduces the size of the valve as a whole, and which can be manufactured inexpensively. SOLUTION: A four-way valve consists of a valve main element A and a driving part B. The valve main body A incorporates both a valve element 4, which has a guide hole 24, which alternately communicates an outlet port 17 to either one of two through holes, against a valve seat 2 in which the inlet port 16, the outlet port 17, and two through holes are formed, and a magnet 25 installed in the valve element 4. The driving part B incorporates a motor that rotates a magnet 26, which possesses an N-pole and an S-pole both of which are opposite in the direction of the pole to those N- and S-pole of the magnet 25 within the valve element A, via a rotor 27. In the four-way valve, the motor 21 within the driving part B is integrated into one body with a motor case 29.
