The driver has a hydraulic cylinder (12) with a working piston (59) shiftably disposed in the cylinder for emitting throwing energy direct to the shuttle. There is also a supply valve (11) connected to the hydraulic cylinder (12) and distributing hydraulic fluid from a pressure medium source to the hydraulic cylinder (12) by the intermediary of a pressure accumulator (9) mounted on this cylinder. The supply valve is controlled by a magnet valve (10) directly connected to one end of the supply valve.
