Abstract
A brake corrector (10) subject to the load of a vehicle is equipped with a fluidic pressure sensor (42; 142), the corrector (10) comprising a body (11) having a bore (12) in which is mounted slidably a piston (20) designed to interact with a valve element (26) in order to control a fluid passage between an inlet (38) and an outlet (32) of the corrector (10). The sensor (42; 142) comprises a piston (56; 156) mounted slidably in a cylinder (50, 150) and moved in the cylinder (50, 150) by way of a suspension spring (48; 148) of the vehicle in which the assembly is mounted, the variation of force exerted on the piston (56; 156) causing a variation in pressure of the fluid contained in the cylinder (50, 150). The corrector (10) and sensor (42; 142) are connected fluidically so that the pressure variation acts on the piston (20) of the corrector. The sensor (42; 142) is shaped so as to interact with one end (60) of the suspension spring (48; 148) and has a shape substantially matching that of the one end (60).
