Patent ID: 8757209

Claim:
A solenoid pressure control valve comprising: a metal insert having a fluid passage formed in said metal insert with upper and lower internal bearings; a composite valve body disposed at least partially around said metal insert; a supply port disposed through said composite valve body and said metal insert, wherein said supply port is connected to said fluid passage; a control port disposed through said composite valve body and said metal insert, said control port being connected to said fluid passage; an exhaust port disposed through said composite valve body and said metal insert, said exhaust port being connected to said fluid passage; a spool valve member at least partially disposed and aligned in said metal insert for controlling the flow of fluid medium between said supply port and said control port, wherein said valve member has a bore extending at least partially through said valve member for providing flow between said supply port and said control port; two or more metering orifices extending through said valve member between said bore and said fluid passage; metering lands positioned between upper and lower bearings, said metering lands having upper and lower flat metering edges engaged to said metering orifices, wherein said valve member controls the flow of fluid between said control port and either said supply port or said exhaust port by moving with respect to said metering lands; a solenoid portion having a coil with an armature moveable within said solenoid portion in response to the energization of said coil, wherein said armature is operably configured to contact said valve member and causes said valve member to slide within said fluid passage; and a spring operably connected to said armature for biasing said armature in one direction when said coil is not energized.
