Title:
MOTOR OPERATED
Document Type and Number:
Japanese Patent JPS61278674
Kind Code:
A
Abstract:
PURPOSE:To simplify configuration by making a section piece with a hollow cylindrical shape of a nonmagnetic material. CONSTITUTION:A hollow cylindrical section piece 3 of a nonmagnetic material is arranged between a stator 1 and a rotor 2, with the section piece 3 as a valve pressure bearing member. A valve hole 5 is bored through a periphery wall of a cylindrical valve body 4 driven by the rotor 2. Further, valve opening areas of the valve hole 5 and a fluid passage 6 are changed in proportion to the rotation angle of the rotor 2. With this constitution, a motor operated valve of simple configuration without external leakage of controlled fluid can be obtained.
