<p>PROBLEM TO BE SOLVED: To reduce the size and cost of a motor valve in which a bleeding port is formed between a valve element and an orifice in a closed state.SOLUTION: A motor valve is configured so that a bleeding port in which refrigerant of a minute flow volume circulates is formed between a valve element 17 and an orifice 12 in a state in which a stopped portion 172 abuts on a stopper portion 182 formed in a valve main body 110. An insertion hole 181 is larger in diameter than a fitting hole and a valve shaft 116, the stopper portion 182 is provided to face a first pipe 20 in a valve chamber 111, and a pressure equalizing passage 185 communicating an interior of a can 30 with the valve chamber 111 is formed in a portion of the insertion hole 181 closer to the first pipe 20 in a state in which the stopped portion 172 abuts on the stopper portion 182.</p> |
