Abstract (en)
The device for the speed synchronisation of two vibrators consisting of the first and second closed hydraulic circuits (13 and 14) to which two control pumps (11 and 12), two hydromotors (15 and 16) and one proportional throttle valve (18) are connected, when the mentioned closed hydraulic circuits (13 and 14) with one by-pass piping (16) drive two vibrators (20 and 21) with the eccentric weights (22 and 23) and are equipped with two position sensors (24A and 24B) the signals of which are sent to the control unit (19).
