Abstract
Improvements in pressure imbalance indicators for braking systems, of the type that comprise a double control circuit of the type in which a plunger is mounted in a sliding position in a cavity of a housing box in order to define two chambers in the latter. pressure gauges adapted to be connected respectively to the two braking control circuits, a return device intended to oppose the displacement of the piston on either side of a normal centered position when the differential pressure between the two opposite chambers remains below of a certain value, and a commutator device controlled by a movable diving piston that acts as a sensing organ, and which is designed to cooperate with a cam-acting stop surface arranged on the piston to regulate the closing of the switching device when moving the piston beyond its normal position, expensive cterized by the fact that friction means are arranged in said imbalance indicator to retain the plunger plunger in its position corresponding to the closing of the switching device, when the plunger returns to its normal centered position under the action of the return device.
