Abstract
The compensator (20) comprises a housing in which there are disposed a compensator piston (30) between an inlet chamber (38) and an outlet chamber (42), and a pilot piston (48) between the outlet chamber (42) and a pilot chamber (52), the two pistons controlling a compensator valve (46) disposed in a passage (44) connecting the inlet and outlet chambers. A pilot valve (90-92) controlled by an inertia weight (72) is mounted in a passage (82, 80, 70, 88, 84, 86) connecting the inlet chamber (38) and the pilot chamber (52). A spring (94) returns the weight (72) in the direction of opening of the pilot valve (90-92). According to the invention, the spring (94) is interposed between the compensator piston (30) and the inertia weight (72). A compensator of this type is used in the braking systems for motor vehicles.
