Abstract

A one-piece valve cartridge assembly for controlling fluid flow in a vehicle has a valve actuator, first and second valve members and a valve cap. The actuator has a piston which is extendable and retractable along a longitudinal axis, with the valve members being provided at opposite ends of the actuator body. The valve cap includes a central, longitudinally extending sleeve portion to receive the free end of the piston with an interlocking fit. The piston may have an annular groove which interlocks with an annular bead inside the sleeve portion of the valve cap. The interlocking fit prevents separation of the assembly components during manufacturing and shipping, with axial alignment of the assembly is maintained by a close fit between the piston and the sleeve portion.
