MECHANICAL HYDRAULIC PUMP INSTALLATION WITH BUILT-IN RADIATOR Russian patent published in 2018 - IPC F04B23/04 F04B47/04 

FIELD: motors and pumps.

SUBSTANCE: group of inventions refers to a mechanical hydraulic pumping unit. Mechanical hydraulic pumping unit with an integrated radiator is characterized in that it includes a bi-directional valve. It is designed to summarize the flows from the primary and secondary pumps to drive the hydraulic actuator at high speed and a small force, or separate these flows from the primary and secondary pumps to drive the hydraulic actuator at low speeds and with great force. This is ensured by recycling the flow from the secondary pump to the oil tank. At the same time, the hydraulic actuator is arranged to cyclically move to the upper or lower positions according to the signals of the respective sensors with which the pump unit is equipped.

EFFECT: technical result is higher reliability of the device.
