Abstract
In a housing (10), a stepped piston (40) bounds an inlet chamber (20) with its smaller face (A36) and an outlet chamber (24) with its larger face (A38). These two chambers (20, 24) are connected to each other by a valve (44, 46) which is controlled by the stepped piston (40). The inlet chamber (20) is also bounded by an auxiliary piston (30). Between the two pistons (30, 40), a spring (54) is arranged which tends to hold the stepped piston (40) at a first stop (52) against the pressure in the outlet chamber (24) and to hold the auxiliary piston (30) at a second stop (56) against the pressure in the inlet chamber (20). The difference between the faces (A38-A36) of the stepped piston (40) is greater than the operative face (A30-A36) of the auxiliary piston (30) on the inlet side. Movement of the auxiliary piston (30) in the direction of the outlet chamber (24) is limited by a third stop (58) formed on the housing (10), said stop not interfering with the freedom of movement of the stepped piston (40). The brake pressure regulator, which is preferably connected in series to one or more rear-wheel brakes, thus takes on a regulating characteristic which closely conforms to the ideal, almost parabolic curve of pressure in the rear- wheel brakes in relation to the pressure in the front-wheel brakes.
