<p>A device for preventing the unintentional restarting of motors or machines is proposed, it being possible to control the supply of energy to the motor or to the machine by means of a control valve with a mechanically adjustable control element and it being possible to connect the control valve non-detachably to the motor or to the machine, the energy for the motor being generated by means of compressed air, and in that a pneumatic piston, to which the primary air pressure prevailing upstream of the motor and upstream of the control valve can be applied, being arranged as a restarting inhibitor between the control valve and the motor, and in that, in order to apply the primary air pressure, a connecting line being arranged between the motor and the piston.</p> |
