<p>PROBLEM TO BE SOLVED: To use only one pressure transducer to monitor the pressure in a hydraulic control system and the pressure in a pressure accumulator. SOLUTION: The pressure transducer 70 and a pressure source 75 are connected to a control valve 20. At a 1st position of the control valve 20 the pressure source 75 is insulated from hydraulic systems 14, 15, 21, and 22 and connected to the pressure transducer 70 and at a 2nd position of the control valve 20, the pressure source 75 and pressure transducer 70 are connected to the hydraulic systems 14, 15, 21, and 22.</p> |
