Title:
SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2016089870
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a bearing structure of a valve shaft capable of preventing transmission of torque of a valve shaft based on torque of a motor to a valve element, preventing abrasion of a valve seat even when an axial core of the valve shaft is deviated, further properly setting a valve function, and suppressing increase of the number of components.SOLUTION: In a bearing structure of a valve shaft composed of a flange portion 41b formed on a lower end portion of a valve shaft 41 axially movably inserted to a cylindrical valve guide 18 integrally axially moving with a valve element 17 by being fixed to an upper outer peripheral face of the valve element 17, and the valve guide 18, a through hole 18a is formed on a ceiling portion 21 of the cylindrical valve guide 18, a plurality of balls are disposed between the ceiling portion 21 and the flange portion 41b, and further a holding portion for restricting falling of the balls is disposed between the balls and the valve guide 18.SELECTED DRAWING: Figure 1
