摘要： A method of compressing a gas includes maintaining a first volume of liquid in a first high pressure chamber and maintaining a first volume of gas in a second high pressure chamber, wherein the first volume of gas is at a first pressure and the first high pressure chamber and the second high pressure chamber are fluidly connected through a high pressure pump. A pressurized gas is forced into the first high pressure chamber having the first volume of liquid and simultaneously pumping, using the high pressure pump, at least a portion of the first volume of liquid in the first high pressure chamber to the second high pressure chamber, wherein the first volume of liquid pumped into the second high pressure chamber compresses the first volume of gas in the second high pressure chamber to a second pressure greater than the first pressure.

摘要： The present invention is directed generally to a system and method which employ a compressed gas-driven device with a passive thermodynamic composition. Certain embodiments provide a compressed gas-driven (e.g., CO2-driven) device implementation that includes a passive thermodynamic composition which allows for extended use of the device without freezing and without requiring a persistently-maintained, active (e.g., electrically-powered) heating. Further, certain embodiments provide a compressed gas-driven (e.g., CO2-driven) device implementation that includes a passive thermodynamic composition which allows for extended use of the device without freezing and without requiring an ignition heat source (e.g., electrically-powered or pyrotechnic as generator) for heating the device. In one embodiment, a CO2-driven sanitizing device is provided for dispensing a sanitizing solution, wherein a passive thermodynamic composition is employed for enabling substantially-continuous use of the sanitizing device for an extended time without requiring an on-board active heater.

摘要： Corrosion resistance is provided for a power cylinder by providing a preloaded molded urethane elastomer sleeve liner within an outer cylinder of material such as a copper/nickel alloy which is subject to corrosion from long-term exposure to ambient fluids such as sea water. Preloading is preferably provided by thermal shrink fitting of the molded urethane sleeve liner to the inner bore of an outer metal cylinder. Preloading of a structure which has high structural integrity and low permeability thus effectively prevents incursion of fluids and gases at the interface between the outer cylinder and the sleeve liner as well as providing a surface which can be machined to a high degree of smoothness and against which reciprocating piston seals and wear assemblies can directly ride and which is resistant to abrasion therefrom even at high piston speeds.
