Abstract
A valve assembly includes a hydraulic subassembly with a valve member displaceable along a valve axis for controlling flow of fluid. The valve assembly also includes a solenoid subassembly for selectively displacing said valve member. The solenoid subassembly includes a metallic solenoid housing having an open end and a solenoid housing base. The solenoid subassembly also includes a solenoid coil assembly disposed within the solenoid housing, the solenoid coil assembly having a coil wound around a plastic spool defining a spool bore extending through the spool. The solenoid subassembly also includes a metallic solenoid housing cover closing off the open end of the solenoid housing and attached to the solenoid housing with a crimp connection. The solenoid subassembly also includes a metallic column disposed within and passing through the spool bore extending from the solenoid housing base to the solenoid housing cover.
