  • Fig. 2 shows the lifting column 6 with a substantially gimbal pivotable Support frame 9 - the actual patient support surface (1 in Fig. 1) is removed. Same or at least functionally corresponding parts have the same reference numerals as provided in Fig. 1.
  • the base fastening of the lifting column is not shown in both figures 6 or the usually existing cladding thereof.
  • the lifting column 6 together with the attached units is an independent unit constructed and only requires an electrical connection to the pump of the Compact unit 7 or to the control unit 8 and any control lines to one not shown remote control or the like.
  • FIG. 3 shows a compact unit 7 together with control unit 8 and three Pressure medium motors shown, as they are known in the prior art with seat valve chain the control unit 8 for controlling or adjusting a Find patient support area (for example 1 according to FIG. 1).
  • the compact unit 7 is an optionally switchable pump 10 with a changeover valve 11 the tank 12 and on the other hand connected to two connections A, B. Before the connections A, B, two mutually unlockable check valves 13, 14 are still switched on - Two adjustable pressure relief valves 15, 16 on the tank side.
  • control unit 8 there are two seat valves for each of the pressure medium motors 2, 3, 3 ' 17 provided, which is spring-loaded on one side and by means of the other side Switching magnets (Y3 to Y8) are adjustable.
  • the associated connections on the pressure medium motors 2, 3, 3 'and also on the entire control unit 8 are again with A and B. designated.
  • Appropriate pressurization of ports A, B can be assumed Pressure medium motors 2, 3, 3 '(the latter is, for example, the one from the 1 and 2 not visible pressure medium motor for height adjustment) retracted or extended be what corresponding adjustment movements of the patient support surface (1 in Fig. 1) or the support frame 9 (Fig. 1 and 2) due.
  • the separate adjustability is required here two seat valves for each of the pressure medium motors, making a total of six solenoids and appropriate control with both supply voltage and hydraulic medium conditionally. Overall, this arrangement is relatively complex and also vulnerable for operating errors.
  • FIG. 4 shows a further function that is essentially the same as that of FIG. 3 Arrangement according to the prior art is shown schematically. Same or from the Functional parts are again with the reference numerals used previously Mistake.
  • the compact unit 7 here has a pressure connection identified by P. and a connection to tank 12 marked with T, between which a pressure relief valve 18 connected in parallel and a spring-loaded check valve 19 in series is.
  • the pump 10 which has only one direction of rotation, sucks from the tank 12 via a filter 20 forth and depending on the switching position of three slide valves 21 pressure on the selected Side of the hydraulic cylinders (2, 3, 3 ').
