Title: Hydraulic motor with two switching stages and automatic control by way of the pressure supply
Inventor: GUEDE DIETER
IPC: E21B44/04
Filed: 1993-07-15
Abstract: A hydraulic motor with two switching stages is controlled automatically by way of the pressure supply and, moreover, without the occurrence of a disadvantageous stop-and-go effect during the switching operation. This is achieved by assigning to the pilot valve a control valve via which the pilot valve is supplied continuously with control oil and by integrating into a control line of the hydraulic motor a pressure switch set to a lower pressure and a pressure switch set to a higher pressure, the pressure switch and the control valve being connected via locking all-or-nothing relays and time-delay relays. By means of the time-delay relay, the stop-and-go effect is bridged in a controlled manner, making it possible to switch without problems from the so-called HS/LT mode into the HT/LS mode and vice versa. <IMAGE>
