FACILITY FOR PUMPING BURNING GASES UNDER HIGH PRESSURE Russian patent published in 2010 - IPC F04B9/12 

FIELD: machine building.

SUBSTANCE: facility consists of cylinder, of inlet and outlet gas valves, and of piston actuated with fluid. Inside the cylinder has a partition with a through orifice dividing the cylinder in two parts; pistons are installed in its each part; a plunger is inserted into the orifice of the partition. Each cavity of the cylinder is connected with an inlet main consisting of a hydraulic pump, electric valves and pressure sensors and with an outlet main consisting of electric valves and a drain tank. A sensor of ultimate end position of the piston is installed in the case of the cylinder. All sensors and electric hydraulic valves are coupled with a control processor. From the side of inlet and outlet valves of gas there is installed a sensor of end left position of the piston instead of the second pressure sensor. Ratio of plunger cross section area to area of the piston is within interval ½-1/5. A membrane compressor of low pressure ensures preliminary compression of burning gases.

EFFECT: raised efficiency and safety of facility at pumping burning gases under high pressure.
