PUMP Russian patent published in 2011 - IPC F04F1/00 

FIELD: engines and pumps.

SUBSTANCE: pump is intended to lift liquid from bore holes and wells, and namely to produce water and can be used in oil industry. Pump includes cylinder with bottom equipped with suction valve and filter, head equipped with inlet branch pipe tightly connected to air pipeline and outlet branch pipe passing through the whole cavity of cylinder installed between its end surface and bottom with a gap, and tightly connected to liquid pipeline with check valve. Cycle frequency control is made in the form of reservoir unbalanced on its rotation axis. It has counterweight and carrying capacity control. Cylinder with pipelines is arranged in casing pipe. Free end of liquid pipeline is interconnected with reservoir of cycle frequency control. Reservoir of cycle frequency control is provided with the cover acting as carrying capacity control with possibility of its being moved in guides, thus forming a slot for outlet and setting of the required water efflux velocity to consumer reservoir; its rotation axis is installed on individual frame above consumer's reservoir and equipped with clutch coupling equipped with protrusions and installed on axis of the control reservoir, cycle frequency. Valve body is rigidly connected to bracket. Frame is installed on end surface of reservoir of consumer. Free end of air pipeline is tightly connected to double-acting valve outlet. Outlet end of valve is tightly connected to the first additional pipeline. Free end of the latter is tightly connected to outlet of reduction gear of high pressure reservoir. High pressure reservoir is equipped with additional inlet seat with thread, which is tightly connected to the second additional high pressure pipeline, the free end of which is tightly connected to the compressor outlet. Brake cylinder is kinematically connected to the brake band installed on brake pulley rigidly connected to shaft of air vane.

EFFECT: energy economy.
