Abstract
A fluid pump may include a fluid chamber, a plunger configured to reciprocate within the fluid chamber, and a valve system including multiple valves. The multiple valves each may be configured to control fluid flow into the fluid chamber or each may be configured to control fluid flow out from the fluid chamber.
Claims20
A hydraulic fracturing pump, comprising:
- a power end;
- and
- a fluid end, comprising:
- a fluid chamber in fluid communication with one or more fluid inlets and one or more fluid outlets;
- a plunger configured to reciprocate within the fluid chamber;
- and
- a valve system, in the fluid end, comprising:
- a valve seat defining multiple bores,
- multiple valves wherein each of the multiple valves is configured to control fluid flow through the one or more fluid inlets or through the one or more fluid outlets, and wherein the multiple valves are further configured to sealingly engage the valve seat at respective bores of the multiple bores,
- a plurality of biasing elements configured to respectively bias the multiple valves to a closed position, and
- one or more retainer elements engaged with the plurality of biasing elements,
- wherein a quantity of the one or more retainer elements is less than a quantity of the plurality of biasing elements, and
- wherein the one or more retainer elements comprise a single retainer element that is common with multiple biasing elements of the plurality of biasing elements.
10 more elements
A fluid pump, comprising:
- a fluid chamber;
- a plunger configured to reciprocate within the fluid chamber;
- and
- a valve system comprising:
- one or more valve seats defining multiple bores,
- multiple valves configured to sealingly engage the one or more valve seats at respective bores of the multiple bores, wherein each of the multiple valves is configured to control fluid flow into the fluid chamber or out from the fluid chamber,
