SYSTEM AND METHOD FOR CONTROLLING A PHASE CHANGE MOTOR USING TRANSMISSION OIL Russian patent published in 2019 - IPC E02D7/18 

FIELD: machine building.

SUBSTANCE: invention relates to vibrating hammer means. In particular, disclosed is a system for controlling a phase change motor using transmission oil, used in hydraulic vibrating hammer, pipe driving plants, which provides lubrication of the transmission and control of the phase change motor by means of the same oil circulating in a closed circuit. Said system comprises, at least, one phase change motor performing energy transfer by means of oil, at least one transmission installed in vibrating hammer or pipe driving unit, at least one crankcase tray, in which oil is accumulated, which is supplied to phase change motor and in transmission, at least one oil pump, suction oil, located in oil pan, guiding it to transmission and engine of phase change and providing circulation of oil inside system, control valve, including at least one oil inlet, at least one A direction control and at least one control input, at least one control valve, which in accordance with a signal supplied through the control input, to control the phase change motor, oil is used, which is used for lubrication of transmission, to the phase change motor and directs oil used to control the phase change motor, back to the transmission lubrication system, providing oil circulation between the transmission and the phase change motor in a closed circuit.

EFFECT: longer service life of the vibrating hammer.
