Title:
SOLENOID VALVE
Document Type and Number:
WIPO Patent Application WO/2023/203898
Kind Code:
A1
Abstract:
This solenoid valve (1) comprises: a coil (2); a stator core (3) having the coil on the outside thereof and a bore (12a) on the inside thereof; a valve (4) which is disposed in the bore (12a) so as to be capable of reciprocating in the axial direction of the bore; and has sliding parts (21, 22) disposed on the outer circumferential thereof; and slid parts (31, 32) which are disposed on the inner circumference of the bore (12a) and on which the sliding parts (21, 22) of the valve (4) slide when the valve (4) reciprocates. The solenoid valve (1) is configured so that the stator core (3) suctions the valve (4) in the axial direction by means of magnetic force generated in the coil (2) for the purpose of causing the valve (4) to reciprocate. One portion of the outer circumference of the valve (4) forms a magnetic circuit (16) between the portion and the stator core (3) and the other portions of the outer circumference of the valve (4), which do not form the magnetic circuit (16), serve as the sliding parts (21, 22).
