Abstract
A solenoid valve has a body with a fluid passage extending longitudinally at least partially through the body. Each of supply, control, and exhaust ports is disposed through the body and operably connected to the passage (the supply port also introducing fluid medium from a pressure source). Among the ports, there is a valve member operably disposed in the passage. A bore extends at least partially through the member. A metering orifice connects the passage or exhaust port with the bore. A solenoid portion has a coil with an armature movable within the portion in response to energization of the coil, and a shaft is connected to the armature. The shaft extends partially into the body and directly contacts the member, and the energization of the coil causes the shaft to slide within the solenoid portion and move the member in response to movement of the armature within the portion.
