摘要： A control valve includes a shaft, a stopper mechanism, and a can. A stator coil is coaxially mounted around the can. Positions in a rotating direction of the rotor and the stator when the shaft is stopped by an operation of the stopper mechanism are set to be reference positions at which magnetic poles of the stator and those of the rotor are opposite to each other. The rotor is configured to be stopped at the reference position by an arrangement of the stopper mechanism. The stator coil is positioned relative to the body according to a positional relation between a fitting part formed on surfaces of the stator and the body attached to each other and an insertion part where the can is inserted into the stator, and magnetic poles of the stator and those of the rotor are made opposite to each other at the reference positions.

摘要： A control valve according to an embodiment includes: a body having an inlet port, an outlet port, and a valve hole that communicates the inlet port and the outlet port together; a valve element configured to open and close a valve section; a drive mechanism configured to drive the valve element; a stepping motor having both a rotor for operating the drive mechanism and a stator for rotationally driving the rotor; and a can that is a cylindrical member covering a space where the valve element and the drive mechanism are arranged and involving the rotor and that defines a pressure space and a non-pressure space. The can is fixed to the body with a ring screw, and the stator is arranged at an outer circumference of the can and fixed to the body with a screw member.
