Patent attributes
A solenoid valve for a slip control system in a vehicle is disclosed. A flow passage is provided in which working fluid such as oil that generates a break hydraulic pressure flows from the side of a solenoid valve through a filter, flows to the front of a plunger through a side hole formed in a valve body of the solenoid valve, and then flows along the side of valve body, that is, is discharged out of an outlet through a side space between valve body and a valve seat. Therefore, linear pressure control is easy because working fluid flows into toward the front of valve plunger through a side inlet of solenoid valve and the entire size is reduced because a special channel for guiding working fluid to the front of the valve plunger is not needed in a pump housing case.
