Title:
SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2014211171
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the interruption of the smooth forward and backward movement of a plunger and a valve element due to the accumulation of foreign matters by suppressing the entry of pressure oil into the rear end side of the plunger on which electromagnetic force works.SOLUTION: In a solenoid valve which is formed with the inner diameter of a cylinder part 2 larger than the outer diameter of a plunger 1 so that the plunger 1 can be inclined, an inclination mechanism is provided for inclining the plunger 1 inside the cylinder part 2 with electromagnetic force when an electromagnetic coil 8 is energized to move the plunger 1 backward so that a valve element 7 opens an inflow port 3. The inclination mechanism inclines the plunger 1 so that the deflection flow of pressure oil to the inside of the cylinder part 2, due to the valve element 7 inclined together with the plunger 1 to cause the front end of the valve element 7 to be eccentric to the inflow port 3, moves in a direction deviating from the opening end of a breathing communication part 11 when a current energizing the electromagnetic coil 8 has a predetermined current value within an ordinary use range.
