Title:
SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2018189217
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a solenoid valve achieving power-saving.SOLUTION: A solenoid valve 50 includes a valve element 300 that alternately opens and closes a first port 130 and a second port 140 to switch a communication state with an input port 120, and a drive part 400 for driving the valve element 300. The drive part 400 includes: a plunger 430 pressing the valve element 300 on the first output port 130 side; a coil spring 450 urging the plunger 430; a solenoid coil 410 that generates electromagnetic force against the load of the coil spring 450 by energization to move the plunger 430 in a direction in which the plunger separates from the valve element 300: a counter weight 500 pressing the valve element 300 on the second output port 140 side; and a connection member 600 that connects the counter weight 500 to the plunder 430 to apply the load of the counter weight 500 to the plunger 430 in an opposite direction to the gravity direction.SELECTED DRAWING: Figure 1
