DEVICE FOR MANAGING THE PRESSURE OF LIQUID Russian patent published in 2019 - IPC F16H3/72 B60K7/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a fluid pressure regulator downstream of a pump. Drive shaft is connected to the input of the differential, which is mounted concentric with the axis of the drive and has the ability to rotate around the axis. One differential output is connected to the driven shaft driving the pump, and the second – to the leading part, the anchor or the inductor of the controlled electric induction power slip clutch. Mating part of the slip clutch is connected to the drive shaft. Pressure is corrected by the control unit, which receives a signal from the pressure sensor and changes in accordance with it the electrical induction between the armature and the inductor, changing the force that blocks the differential, and hence the gear ratio from the drive to the pump. Differential blocking force can be controlled by changing the magnitude of the excitation electric current on the inductor of the electric induction coupling or by changing the mutual position of the inductor and the armature, changing the gap between them if the magnets of the inductor are constant.

EFFECT: enabling the design simplification.
