Abstract
A siphon pump system for pumping water from a water source to a supply destination. The system includes a holding canister through which the water flows, and a first timing bucket associated with the holding canister for controlling the admission of air into the system to thereby permit flow of water contained within the holding canister. A lower flow control chamber is provided adjacent the outlet from a long, second siphon conduit extending from the holding canister to control the refilling of the holding canister in an automatic manner and without the need for connections with a source of electrical power.
Claims13
A siphon pump system for dispensing a predetermined quantity of water from a water supply source, said pump system comprising:
- a. a destination container for receiving water from the water supply source;
- b. a holding canister including an air inlet valve for allowing air to enter the system and an outlet check valve for controlling the rate of flow of water from the holding canister into the destination container;
- c. a first siphon conduit extending from the water supply source to the holding canister, the first siphon conduit having an inlet within the water supply source and an outlet connected with the holding canister and positioned at an elevation above that of the water supply source;
- d. a second siphon conduit extending from the holding canister to an outlet at an elevation below the level of the water supply source, the second siphon conduit having a longer length than that of the first siphon conduit;
- e. a system flow control valve positioned in the second siphon conduit for controlling the flow of water through the first siphon conduit, the holding canister, and the second siphon conduit;
- f. an anti-backflow valve positioned within and adjacent the outlet of the second siphon conduit, for preventing reverse flow of air into the second siphon conduit from the second siphon conduit outlet;
- g. a flow control valve in the second siphon conduit upstream of the anti-backflow valve for controlling flow of water through the first siphon conduit, the holding canister, and the second siphon conduit;
- and
- h. a charging inlet at an upper end of the holding canister for initially priming the siphon pump system;
- and
- i. an air admitting valve communicating with an upper end of the holding canister for selectively admitting air into the holding canister to permit water to exit from the holding canister when the air admitting valve is open, and for preventing water from exiting from the holding canister and through the anti-backflow valve when the air admitting valve is closed.
