Title:
SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2015218810
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a solenoid valve capable of suppressing operation sound in reciprocated movement of a valve body.SOLUTION: A plunger 20-1 moves onto the side of a valve seat 13 with energization force of a spring 21, and moves onto the side of a pin 19 with electromagnetic attraction force of a solenoid part. A resin valve body 23 provided on the end surface of the plunger 20-1 has a projection part 23a on a surface contacting with the valve seat 13, and a projection part 23b on a surface of contacting with the pin 19. At the time of contact, contact sound (operation sound) is suppressed by elastically deforming the projection parts 23a, 23b.
