Safety device and electrohydraulic paravehiculos provided emergency brake and hydraulic clutch

摘要

Safety device and electrohydraulic emergency vehicles with hydraulic brake and clutch, characterized in that it consists of a solenoid associated cooperatively with a guided in a longitudinal bore of a body and provided with annular grooves shaft in the passive condition of the electrovalve match two pairs of holes transverse passage of said body connected to the hydraulic circuits den vehicle, allowing the circulation of fluids brake clutch pump in the latter case if the device is connected to such a pump from which condition free operation of the vehicle and to be activated the solenoid by acting on the appropriate switch, the above axis is displaced by the same against the force of a spring opposite return so that the annular grooves of the shaft are separated from the holes and circulation is interrupted pumps brake fluid and clutch quedarcerrados said bores, locking the vehicle by stepping on the brake pedal and unblocked after deactivating the solenoid and open the flow through the holes and slots mentioned having become the axis to its open position helped by the return spring again .
