Hydraulic circuit drain equipment - comprises exhauster with vacuum tank and flexible pipes to drainage points in circuit

摘要

The hydraulic circuit drain equipment is particularly for a motor vehicle braking circuit. It incorporates an exhauster (1), connected to a vacuum tank (2a, 2b), in turn connected via flexible pipes (3, 3a-3f) to the drainage points (4) of the circuit. The vacuum tank can comprise two sealed chambers connected externally to each other (9), one receiving the braking fluid drawn in and the other acting as a condensation vessel for the vapours given off by the fluid. There can be a baffle (8) in the condensation vessel to aid the condensation process, and drain taps (12, 13) on either side of the baffle.
