Vorrichtung zum Blockieren eines Hydraulik- oder Druckluftkreises eines Fahrzeuges, insbesondere Bremskreises oder dergleichen

摘要

A device for locking a vehicle multi-way hydraulic or pneumatic circuit, such as a braking circuit or the like, to act in particular as an antitheft device, comprising a block (2) provided with at least two interconnected ducts (5, 6) opening to the outside of said block (2) at apertures (9, 10) to which a vehicle hydraulic or pneumatic circuit is connected, said ducts (5, 6) being interconnected via at least one channel (16). In this latter there is provided a shut-off means (33) in the form of a solid of revolution provided with a through hole (36) and able to assume at least two working positions, in one of which said hole (36) is coaxial with the channel (16) connecting said ducts (5, 6) together, and in the other of which said hole (36) is perpendicular to the axis (K) of said channel (16) so that the shut-off means (33) interrupts communication between said ducts (5, 6), said shut-off means (33) being moved by an actuator member (34) operated by a key (60).
