RECIPROCATING PISTON PUMP - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240052818 titled 'RECIPROCATING PISTON PUMP
Simplified Explanation
The patent application describes a pump system with a housing, pistons, inlet check valves, a directional control valve (DCV), and a relief valve.
- The housing has two internal volumes separated by pistons to create chambers.
- Inlet check valves permit fluid flow into the chambers.
- The DCV can be repositioned to connect different chambers to a high-pressure fluid source.
- A relief valve supplies fluid to the DCV to control its movement.
Potential Applications
- Hydraulic systems
- Industrial pumps
- Automotive fuel systems
Problems Solved
- Efficient fluid pumping
- Controlled fluid flow direction
- Pressure regulation
Benefits
- Versatile fluid handling
- Precise control over fluid flow
- Reliable operation
Original Abstract Submitted
a pump system includes a housing defining a first internal volume and a second internal volume, a first piston positioned to separate the first internal volume into a first chamber and a second chamber, a second piston positioned to separate the second internal volume into a third chamber and a fourth chamber, a first inlet check valve configured to permit fluid flow into the first chamber, a second inlet check valve configured to permit fluid flow into the third chamber, a directional control valve (dcv) repositionable between (a) a first position where the dcv is configured to fluidly couple the second chamber to a high pressure fluid source and (b) a second position where the dcv is configured to fluidly couple the fourth chamber to the high pressure fluid source, and a relief valve configured to supply a fluid to the dcv through an orifice to move the dcv.
