Abstract

A solenoid valve includes: a solenoid body which includes a plunger mounted movably up and down and a stop member disposed on the plunger, and a valve body having an orifice which is open and closed as the plunger moves up and down. The stop member includes a first buffer member formed at a contact portion between the plunger and the stop member.

Description

technical field [0001] The invention relates to a solenoid valve. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] As generally known to those skilled in the art, solenoid valves are electromechanically operated valves. Solenoid valves can be controlled by passing electrical current through a solenoid. [0004] Solenoid valves include a plunger, and the plunger can move when current is applied to the side of the solenoid, and can return to its original position if the current is cut off. [0005] As described above, the plunger contacts other parts during its movement, thereby generating contact noise. In addition, when the contact noise is transmitted to the outside through the bracket, another noise (for example, transmission noise) may occur simultaneously with the contact noise. Specifically, when the pressure of the fluid regulated by the so...
