Patent ID: 7717399

Claim:
A side inlet-typed solenoid valve comprising: a plunger that is elastically supported by a coil spring and a stator that is magnetized by a coil electromagnetic field caused by current applied, and reciprocates by being magnetized together with the stator to open/close an inside channel; a valve body that is connected to the stator through a sleeve and inserted in a valve insert hole communicating with an inlet port and an outlet port of a pump housing case such that a flow passage is formed between the inlet port and the outlet port by the plunger that reciprocates therein; a valve seat that opens/closes the inside channel depending on contact with a check ball provided at the end of the plunger inserted in the valve body; a passage changing channel that is formed in the valve body so that oil that has flowed in the valve body through the inlet port at the side of the pump housing case flows along the side of the valve body, flows in toward the front of the plunger inserted in a body forming channel in a reverse direction to the inflow, and is then discharged out through the outlet port formed in the axial direction of the valve body; an orifice that is formed toward the valve seat and fixed in the valve body by a cover to change the direction of the oil flowing in the valve body through the passage changing channel into an axial direction that is the front of the plunger; and a filter that filters impurities contained in the oil flowing into, at the inlet port of the pump housing case.
