Abstract
A braking correction device comprises two correcting valves of which the inlets are separately connectible to two independent braking pressure sources and the outlets to two independent sets of vehicle brake actuators, each valve having a piston and being capable of controlling the pressures at its inlet and outlet in accordance with a predetermined relationship. The device is also provided with a mechanical control comprising an input member subject to the force generated by resilient return means, two projections arranged in parallel, each of which projection moving on unisson with a corresponding valve piston, a rocker member rotatable relative to the input member, the two projections cooperating with one face of the rocker member on opposite sides of its axis of rotation, a block of imcompressible elastomeric material, said block having substantially the shape of half a body of revolution and being rotatable non-deformably in a complementary cavity formed in a rigid cup fixed to the input member, the other face of the rocker member having a surface capable of making contact with the block bearing on the diametrical section of the half body of revolution.
