Title: Noise Reduction Structure of Solenoid Valve
Inventor: CHO SEUNG BEOM
IPC: F16K31/06
Filed: 2001-12-29
Abstract: PURPOSE: A noise reducing structure of a solenoid valve is provided to reduce the noise by generating a resistance in proportion to the moving speed of a plunger. CONSTITUTION: A plunger(40) of a solenoid valve is opened and closed by upward and downward movements of the plunger. A cohesive fluid(1) having a high viscosity is filled between the plunger and a head portion(50). In moving the plunger upward and downward by the magnetic force and the elastic force of a return spring(60), the adhesive fluid is moved downward through a passage slot(1) formed in the plunger or a cylinder housing(20). A resistance in proportion to the moving speed of the plunger is generated by the adhesive force of the adhesive fluid. By functioning the adhesive fluid as a damper, the noise by shock generated by clashing the plunger to the head portion is reduced.
