Abstract A device comprising a motor housing communicating with a pressure source and with the atmosphere through a traversable valve member operatively interlinked with the engine crankshaft, a link accommodated in the hollow space of the housing traversably in response to a pressure variation therein and operatively interconnected with the actuator of the clutch, a magnet for operating the valve member to disengage said clutch. Said operative association of said traversable member with the engine crankshaft is effected through an electric crankshaft speed transmitter and a transducer unit to convert the frequency of a signal from said electric transmitter into a current magnitude, the input of said unit being electrically connected to said electric transmitter and the output thereof, to the coil of said magnet, the armature of which is interconnected with the valve member. The construction of the device is simple, which enables the device to be located practically at any suitable place of a transport vehicle.
