Abstract (en)
The invention concerns a hydraulic remote control device for an apparatus, especially a high-pressure cleaner. <??>The device is principally constituted, on the one hand, by a hose (2) comprising a device (3) for controlling the starting and stopping of the functioning of the apparatus (1) to be controlled and, if necessary, a cleaning lance (4) and, on the other hand, by a programming device (5) also connected in series with the hose (2) upstream or downstream of the control device (3), integrated or not integrated with the said control device (3) and, finally, by a processing unit (6), continuously and sequentially measuring the pressure in the hose (2) by means of a corresponding transducer (7) and controlling, in particular, the operation of a motor-pump unit (8) feeding the said hose (2) with pressurized fluid, as well as the nature and composition of the said supply fluid, as a function of the pressure or change in pressure measured in the said hose (2). <IMAGE>
