Abstract
An electric valve can be further miniaturized while reducing the number of manufacturing man-hours. The electric valve contains: a motor including a stator member and a rotor member that displace a valve body, and a housing for accommodating the motor. The housing is formed by joining a heat generation portion formed of a first material to a heat receiving portion formed of a second material. The light transmittance in the first material is lower than the light transmittance in the second material.
Claims10
An electric valve comprising:
- a motor including a rotor member and a stator member for applying a rotational force to the rotor member;
- a power transmission mechanism for converting rotational movement of the rotor member into axial movement of a valve body;
- a housing for accommodating the motor and the power transmission mechanism;
- and
- a base member connected to the housing and provided with a valve seat to which the valve body is separated or seated,
- wherein:
- the housing includes:
- a heat generation portion formed of a first material, and
- a heat receiving portion formed of a second material and bonded to the heat generation portion, and
- a laser light transmittance in the first material is lower than a laser light transmittance in the second material.
