proportionality valve sensitive to the load for the hydraulic braking systems, 2004.

摘要

P such a valve is connected via an inlet orifice 30 to a master - cylinder and an outlet orifice 42 to the brake cylinders of the rear wheels of a vehicle. The passage between the two orifices may be restricted by a movable element in the form of a piston 80 which cooperates with a cap made of elastomer 102 in order to limit the braking pressure of the rear wheels. This neck is only when the vehicle is empty or loaded, which is detected in the braking by the movement, under the effect of the deceleration, with a weight in the form of a ball 60 which may prevent or to release the movement of the piston 80. / p
