Abstract: A gas regulator includes a housing and a pressure regulator positioned within the housing along a first axis for controlling the pressure of gas received from a pressurized source. A flow meter controls the flow rate of the gas received from the pressure regulator. The flow meter is positioned relative to the housing along a second axis, transverse to the first axis. An outlet nozzle member has a nozzle stem and is positioned along the first axis. The outlet nozzle member receives the gas from the flow meter and delivers the gas through the nozzle stem.

Abstract: A gas regulator includes a slave valve assembly for receiving and controlling the flow of gas to a desired destination. A timing chamber is positioned adjacent to the slave valve assembly. The timing chamber has an inlet for also receiving the gas. An electronically operated pilot valve assembly is in communication with the timing chamber for operating the slave valve assembly. When the pilot valve assembly is closed, gas pressure within the timing chamber acting on the slave valve assembly closes the slave valve assembly. When the pilot valve assembly is open, gas exits the timing chamber and reduces the gas pressure in the timing chamber, thereby allowing the slave valve assembly to open and deliver the gas to the desired destination.

Abstract: A pump including a first piston positioned within a first chamber having a first inlet and a first outlet. A second piston is positioned within a second chamber and is secured to the first piston. The diameter of the first piston is larger than the diameter of the second piston. The second chamber has a second inlet and a second outlet. The second inlet is in communication with the first outlet of the first chamber. A drive system reciprocates the first and second pistons in unison within the first and second chambers such that fluid is pumped into the first chamber, from the first chamber to the second chamber, and then expelled from the second chamber.
