<p>The four-way selector valve (100) relating to the invention basically comprises a motor (40) which has a stator (41) and a rotor (42), a case, and a main body including a main valve (75) and a valve seat (80), both of which are arranged in a valve chest (73) within the case. A rotor sleeve, which comprises the rotor (70), is equipped with an auxiliary valve (61) which opens or closes the pressure equalization orifice (77) in order to transfer pressure, and an operating pin (64) which moves the position of the main valve (70). The rotor (70) of the motor (40) rotates the auxiliary valve (61) on the main valve (70) and slides the main valve (75) on the valve seat (80) via the operating pin (64). <IMAGE></p> |
