Patent ID: 8075287

Claim:
A fluid pump comprising: an inlet; a plunger that is movable to pressurize fluid drawn from the inlet into a compression chamber; a housing having a cylinder in which the plunger is substantially axially movable and an outlet defining a bore through which fluid pressurized in the compression chamber is discharged, the inlet and the outlet defining a fluid passage therebetween; a check valve that permits fluid to be discharged through the outlet and restricts fluid from flowing into the compression chamber from the outlet, wherein the check valve includes: a valve seat, which is defined in the outlet; and a valve member, which is seatable against the valve seat to restrict the fluid from flowing into the compression chamber from the outlet and is liftable away from the valve seat to permit the fluid to be discharged through the outlet; a solenoid control valve that selectively communicates or blocks the fluid passage to control fluid discharged through the outlet; and a support member that supports the control valve, wherein the cylinder, the valve seat, the support member, the inlet, and the outlet are integrally formed as a single part, wherein an outlet passage radially outwardly extends from the compression chamber, through the valve seat, to an outlet opening along an imaginary straight radial line and includes the bore of the outlet, wherein the outlet serves as a joint adapted to connect with a high pressure pipe, and wherein the outlet protrudes radially outwardly from a remainder of the housing.
