Abstract
PURPOSE: To enable the early detection of the leakage of a braking liquid by using as a leakage sensor a member of high electroconductivity coated with an electroinsulator which is characteristic of being softened and melted by the braking liquid.
CONSTITUTION: A member 1 of high electroconductivity coated with an electroinsulator 2 formed of a material which is softened and melted by a braking liquid, such as, for instance, barnish rosin ester in a shellac alcohol system, wax in a soybean oil system or varnish in a tar pitch naphtha system, is used as a leakage sensor 8, being fitted to a required place on a metal surface positioned in the middle of the course along which the leak of the braking liquid from a hydraulic cylinder device 10 reaches the frictional surface 11 of braking. And the sensor 8 is connected with an alarm device and a power source through a conductor 29, thereby an alarm and detection circuit being constituted. By this device, the sure and easy detection of the braking liquid leaking through between a piston 4 and a cylinder 6 turns to be possible.
