Abstract:
A pump includes a liquid housing having a liquid chamber with a piston/diaphragm assembly arranged therein that responds to a suction stroke and draws liquid into the liquid chamber, and responds to a pressure stroke and provides liquid from the liquid chamber; and a gas housing having a slide valve assembly separating first and second gas chambers. The slide valve assembly responds to a suction-to-pressure-force at the suction stroke conclusion, changes from a suction-to-pressure stroke state, provides gas from the first to second gas chamber through the slide valve assembly, and provides the pressure stroke so liquid passes from the liquid chamber; and responds to a pressure-to-suction-force at the pressure stroke conclusion, changes from the pressure-to-suction stroke state, provides gas from the second chamber through the slide valve assembly, and provides the suction stroke so the liquid is drawn into the liquid chamber.
Abstract:
A high viscosity portion pump system has a single piston portion pump having a piston/diaphragm assembly arranged on a piston shaft forming liquid and gas chambers, which moves from a starting-position and provides high viscosity fluid from the liquid chamber when gas is received by the gas chamber; has an elastic member arranged on a retainer coupled to the shaft in a compartment in a pump housing, which moves the assembly back to the position and draws further fluid into the liquid chamber when the gas is released; and has a piston position sensor that responds to the position of the shaft and provides signaling containing information about when the assembly is in the position or completed a stroke from the position. A gas control system includes a signal processor that receives the signaling, and provides corresponding signaling containing information about when to provide or release the gas.
Abstract:
Apparatus, including a carbonation chamber, is provided that includes a mixing and metering member and a gas adjustment member. The mixing and metering member is configured to respond to a fluid, including water, and an adjustable amount of gas, including CO 2 , and may be configured to provide a mixture of the fluid and the gas. The gas adjustment member is configured to receive the gas, including from a gas inlet, and to provide the adjustable amount of gas to the mixing and metering member, based at least partly on an adjustable axial relationship between the mixing and metering member and the gas adjustment member in order to control a desired carbonation level of the mixture.
