PRESSURE-LIMITING ASSEMBLY FOR USE IN HYDRAULIC OR PNEUMATIC BRAKE SYSTEMS

摘要

Pressure-limiting assembly for use in a hydraulically or pneumatically operated mechanical brake system which is supplied with pressure for releasing the brake by a pump (1) and is discharged to a tank (2), wherein the pressure-limiting assembly consists of at least one normally open switching valve (60.1, 60.2) and also at least one pressure-maintaining arrangement, which is provided between the switching valve (60.1, 60.2) and the tank (2) and can be adjusted to a defined brake pressure, for rapidly reducing the system pressure to a preset pressure level and then staying at the level for a predetermined period.
