Abstract:
1. A valve comprising: a valve body having a fluid passage extending longitudinally at least partially through said valve body; a supply port disposed through said valve body and operably connected to said fluid passage; a control port disposed through said valve body and operably connected to said fluid passage; a valve member operably disposed in said fluid passage 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 the flow between said supply port and said control port; an exhaust port disposed through said valve body and operably connected to said fluid passage, a plurality of metering orifices extending through said valve member between said bore and fluid passage, said exhaust port further including a first portion that extends parallel to said metering orifices, a second portion spaced from said first portion that extends parallel to said metering orifices and an intermediate portion that extends obliquely with respect to said first and said second portions, a metering land operably disposed in a sliding relationship with respect to said valve member and said metering orifices, wherein said valve member controls the flow of fluid between said control port and either of said supply port and said exhaust port by moving with respect to said metering land; and a solenoid portion having a coil with an armature movable within said solenoid portion in response to energization of said coil and a shaft connected to said armature, wherein said shaft extends partially into said valve body and directly contacts said valve member and said energization of said coil causes said shaft to slide within said solenoid portion and move said valve member in response to movement of said armature within said solenoid portion.
