Hydraulic system for vehicle - has single sensor measuring stored pressure and controlling solenoid valves via triggers

摘要

The system has a pressure controller with a single pressure sensor (31) to each pressure storage system (5). The sensor converts the stored pressure into an electrical signal. Hydraulic valves (15,23) control the charging operation of the hydraulic pump (1) and the operational readiness of at least one of the loads (9). The valves are electrically operated via triggers connected to the single pressure sensor. The thresholds of the triggers correspond to different pressures. The hydraulic pump is run continuously. The valve controlling the charging operation is located in a feedback line (17).
