Abstract (en)
[origin: EP0329208A2] The hydraulically driven high pressure cleaner has a minimum of three pistons (2) acted on by hydraulic oil, which act against a second fluid to be displaced. Each piston (2) has a synchronising rod (6) which acts against a rotary device (9-12), whose rotation is caused by the axial movement of the synchronising rods (6). The rotary device (9-12) drives a control gear (22, 51) which controls the hydraulic oil to the pistons (2) acted on by hydraulic oil and away from these, thereby generating their axial movement. <IMAGE>
