Filed:

Jun 10, 2010

Appl. No.:

12/797670

Inventors:

Denis E. Keyes - Staten Island NY, US
John R. Randall - Freehold NJ, US

International Classification:

B67D 7/08

US Classification:

222 64, 222 1, 222162, 222440

Abstract:

A fluid dispensing apparatus is configured to dispense a predetermined volume of fluid, and includes a fluid reservoir to hold a fluid to be dispensed, a dispense tube to dispense the fluid, and an elevator mechanism. The fluid reservoir receives a fluid from a fluid supply. A dispense tube has a dispense outlet, and is connected to an outlet port on the fluid reservoir. The elevator mechanism changes a relative vertical displacement between the dispense outlet and the outlet port. Particularly, a processor controls the elevator mechanism to raise the dispense tube to a raised filling position to prevent fluid flow from the dispense outlet, and lower the dispense tube to a lowered dispensing position to dispense the fluid.

Abstract:

A fluid dispensing apparatus having no moving parts in contact with the fluid includes a fluid chamber and a measuring cup having an open top disposed in the fluid chamber. The fluid chamber is connected to a fluid source which supplies fluid to fill the chamber to a pre-determined level above the top of the measuring cup. As the fluid chamber is being filled, the fluid overflows and fills the measuring cup. A first sensor indicates when the fluid reaches the pre-determined level above the top of the measuring cup and stops the flow of fluid into the fluid chamber. A drain, which is responsive to the first sensor, drains fluid from the fluid chamber until the fluid level drops to a predetermined level below the top of the measuring cup. As the fluid level in the fluid chamber recedes, a pre-determined volume of fluid is captured in the measuring cup. A second sensor indicates when the fluid level drops to the pre-determined level below the top of the measuring cup and stops the flow of fluid from the fluid chamber.
