Abstract
The distributor comprises a body in which a movable brake-operating pusher is mounted for movement as a result of the actuation of the brake pedal. The position of the operating pusher relative to the distributor body is detected by means of a linear potentiometer having a casing fitted into the distributor body and a slide provided with a control pusher adapted to cause the displacement of the slide as a result of the movement of the operating pusher.
Claims6
A control duplex-type pneumatic distributor for controlling a pneumatic braking system for a motor vehicle fitted with an auxiliary slowing device, comprising a body in which a movable brake valve operating pusher is mounted for movement as a result of the actuation of a brake pedal, and electrical sensor means for detecting the position of said operating pusher relative to the body, said electrical sensor means including a linear potentiometer including a casing fitted in said body and a control pusher which is movable through an opening in said casing for controlling the operation of the potentiometer as a result of movement of the control pusher, so that the operation of the potentiometer depends on the position of the operating pusher relative to the distributor body, and mechanical regulating means provided in said body and associated with said casing for enabling the resistance of the potentiometer to be calibrated in correspondence with a reference position of the operating pusher.
