ABSTRACT:
A fluid pump includes a plunger that is movable to pressurize fluid drawn from an inlet into a compression chamber. The plunger is substantially axially movable in a cylinder. Fluid pressurized in the compression chamber is discharged through an outlet. The inlet and the outlet define a fluid passage therebetween. A solenoid valve communicates and blocks the fluid passage to control fluid discharged through the outlet. A solenoid valve support supports the solenoid valve. At least one of the inlet, the outlet, and the solenoid valve support is formed of a ferrous material integrally with the cylinder by monoblock casting.
