Abstract
An improved condiment dispensing system for delivering a measured quantity of condiment at a constant flow rate. The device comprises a pump which is fluidly connected to a condiment source and a dispensing apparatus. The dispensing apparatus includes a valve assembly which is connected to both a pressurized fluid source and to the pump whereby actuation of a valve assembly contained on the surface of the dispensing apparatus causes a measured quantity of condiment to be dispensed from an outlet nozzle contained thereon.
Claims11
A condiment dispensing system comprising:
- at least one reservoir sized to contain a quantity of condiment therein;
- a hand-held dispensing apparatus;
- at least one fluid-driven pump fluidly coupled between said reservoir and said dispensing apparatus for pumping condiment from said reservoir to said dispensing apparatus, said pump being adapted to draw a pre-determined quantity of the condiment from the reservoir thereinto and dispense the pre-determined quantity therefrom into the dispensing apparatus;
- and
- a valve assembly disposed within said hand-held dispensing apparatus, said valve assembly comprising:
- a plurality of fluid passages in fluid communication with said pump;
- and
- at least one valve stem, said valve stem being reciprocally movable between first and second positions;
- said fluid passages and said valve stem being oriented within said dispensing apparatus in a manner wherein said valve stem is operable to selectively open certain ones of said fluid passages while simultaneously closing others such that said valve stem causes said pump to draw the pre-determined quantity of condiment from the reservoir thereinto when in the first position and dispense the pre-determined quantity therefrom into the dispensing apparatus when in the second position.
