Title:
SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2014234912
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve seating performance of a valve element in a constantly-closed type solenoid valve.SOLUTION: A pilot valve element 50 has a shape in which a cross section of one end part becomes smaller toward its tip, and it is attached to/detached from a pilot valve seat 66 by the tip part being inserted into/extracted from a pilot valve hole 26. Then, the pilot valve element 50 displaces relatively with respect to a plunger 34 when it is seated on the pilot valve seat 66; thereby, the pilot valve element 50 can be aligned with respect to the pilot valve hole 26 autonomously. That is, clearance CL1 in a radial direction between the pilot valve element 50 and the plunger 34 is set to be larger than clearance CL2 in the radial direction between the plunger 34 and a sleeve 30.
