PENDULUM PUMP DRIVE Russian patent published in 2016 - IPC F04B17/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to devices lifting the liquid from reservoir and can be used to transportation of fluids for industrial and household needs in energy- and resource-saving modes. Drive comprises immersed in feeding tank cylindrical casing with outlet pipe, which arranges back-and-forth movable piston with check valve. Piston is rigidly fixed on the rod lower end, upper end of which is hinged via a lever and is connected to the first end fitted on axle of the link, which is connected to driving pendulum through of attachment axis located on its second end. Drive pendulum is made in the form of a Pelton turbine with balance weight. Additionally equipped with drive in the form of electric motor, which is located on one shaft with turbine. Motor flange is rigidly fixed on the second end of the link. Under turbine there is collecting tank connected via drain hose with feed tank. Drive is equipped with hydraulic control system including hydraulic accumulator, tee, injection pipe, delivery and return valves, overflow valve and flexible hose with nozzle rigidly fixed on the crank and arranged tangentially to the blades of Pelton turbine. Outlet pipe of the pump is connected via t-joint with hydraulic accumulator and pressure pipe with discharge valve. On delivery tube the transverse branches with return valve and overflow valve are installed connecting the pressure pipe with a flexible hose.

EFFECT: provides water supply practically free of losses, regulation of water flow rate depending on number of consumers at observance of the power saving mode.
