Patent ID: 8840383

Claim:
A high pressure fluid pump comprising: a piston housing; a pump head connected to and supported by the piston housing; and a pump pedestal for supporting the aforementioned pump head and the piston housing; the pump head receiving fluid at a low pressure, and, in combination with the piston housing, producing fluid through a first chamber at a high pressure; the combination of the piston housing and the pump head containing a first one-way check valve, at least one piston, and a second chamber that accommodates movement of the piston, wherein the first one-way check valve in response to a suction on one side of the first one-way check valve, allows the received fluid at the low pressure to pass through an inlet of the first one-way check valve along an axis of the first one-way check valve and into a first chamber and to pass through the first chamber along a longitudinal axis of the first chamber, and, in response to the high pressure in the second chamber enables fluid at the high pressure in the first chamber to pass through the first one-way check valve to an outlet port while blocking the inlet of the first one-way check valve, wherein, during a stroke toward the first chamber, the piston compresses the fluid in the first chamber to produce fluid at the high pressure, causes the fluid at the high pressure to pass through the first chamber and the first one-way check valve along the longitudinal axis of the first chamber and into a third chamber, and causes the fluid at the high pressure to pass through the third chamber along a longitudinal axis of the third chamber and into the outlet port along an axis of a second one-way check valve; wherein the longitudinal axis of the first chamber is perpendicular to the axis of the first one-way check valve; wherein the longitudinal axis of the third chamber is perpendicular to the axis of the first one-way check valve; and wherein the axis of the second one-way check valve is perpendicular to the axis of the first one-way check valve.
