Hydraulic circuit e.g. high pressure hydraulic circuit, for e.g. dual-coupling gear box of motor vehicle, has partial high-pressure hydraulic circuits with pressure sensors and pressure accumulators and connected upstream of safety valves

摘要

The circuit has two partial high-pressure hydraulic circuits (4, 5) with pressure sensors (6, 7) and pressure accumulators (8, 9). The hydraulic circuits are connected upstream of safety valves (12, 13). Actuators are provided as piston units, where gear stages of a gear box are controlled by the piston units. The pressure sensors, the pressure accumulators and the safety valves are arranged in a separate and/or common valve block.
