DEVICE FOR DETECTING THE PRESENCE OF SMALL OR MINIMAL LEAKS IN THE HYDRAULIC SYSTEM OF VEHICLES

摘要

The present invention relates to a device for detecting the presence of small or minimal leaks in the hydraulic brake system of vehicles. In order to increase the yield while minimising dimensions as much as possible, the pressure rod comprises a non-rotating spindle (6) which is driven by a rotating nut (6.1) and which supports the measuring head (3). A support plate, which is spring-loaded so as to be capable of displacement with a little friction, is further provided within the measuring head (3).
