Abstract
A pressure reduction system for supplying fluid from a pressurized source to a hand operated pump, such as a pitcher pump or similar style manual pump, is disclosed. The system regulates the pressurized fluid from the source so that only the desired amount of fluid at substantially atmospheric pressure is supplied to the hand pump inlet when needed or called for by the pump.
Claims18
A fluid control system for supplying fluid from a pressurized fluid source to a hand operated pump, the control system comprising:
- a vessel having a fluid cavity;
- said vessel having a vessel inlet and a vessel outlet formed therein;
- a float valve, said float valve having a float valve inlet and a float valve outlet;
- said pressurized fluid source coupled to said float valve inlet;
- said float valve positioned to regulate a flow of pressurized fluid into said fluid cavity;
- said float valve outlet located within said fluid cavity;
- a check valve coupled to said vessel outlet;
- said hand pump having a pump inlet, said pump inlet being coupled to said check valve;
- and
- wherein fluid at atmospheric pressure is withdrawn from said vessel through said check valve when said hand pump is operated.
A fluid control system for supplying fluid from a pressurized fluid source to a hand operated pump, the fluid control system comprising:
- a vessel defining a fluid retaining cavity;
- said vessel having a vessel inlet opening and a vessel outlet opening;
- a float valve having a float valve inlet and a float valve outlet, said float valve inlet coupled to said pressurized fluid source and said float valve outlet positioned to allow fluid to flow into said fluid retaining cavity through said vessel inlet opening;
- said float valve having a float located within said fluid retaining cavity;
- a check valve coupled to said vessel outlet opening;
- said check valve having a check valve outlet connected to said hand operated pump;
- and
- wherein said fluid from said pressurized fluid source is controllably dispensed through said float valve into said fluid retaining cavity and fluid at atmospheric pressure flows out of said vessel through said check valve when said hand pump is operated.
A liquid control system for supplying pressurized liquid from a pressurized liquid source to a hand pump, the liquid control system comprising:
- a vessel;
- a float valve having a float valve inlet coupled to said pressurized liquid source and a float valve outlet positioned to flow into said vessel;
- a liquid outlet formed in said vessel and coupled to a check valve;
- said check valve coupled to said hand pump;
- and
- wherein said pressurized liquid from said pressurized liquid source flows through said float valve into said vessel and liquid at atmospheric pressure flows out of said vessel and through said check valve when said hand pump is operated.
