DRIVE SYSTEM WITH AN APPARATUS FOR INTERRUPTING THE OPERATION IN THE CASE OF AN IMMINENT LACK OF OPERATING MEDIUM
First Claim
1. A drive system comprising:
- an engine;
a tank container for storing an expendable operating medium for the engine;
a filling level monitoring device for monitoring the filling level in at least one of the tank container in a feed line from the tank container to the engine; and
an interruption device for interrupting the operation of the engine when the filling level monitoring device determines that the filling level has sunk below a predetermined filling level, wherein the filling level monitoring device has a sensor for monitoring the filling level, the sensor being situated on or in the feed line in such a way that the feed line has a continuous incline from the position of the sensor up to the tank container.

Abstract
A drive system has an engine, a tank container for storing an expendable operating medium for the engine, a filling-level monitoring apparatus for monitoring the filling level in the tank container and/or in a feed line from the tank container to the engine, and an interruption apparatus for interrupting the engine in the case of an imminent lack of operating medium. If the filling level drops below a predefined filling-level height, this is detected by the filling-level monitoring apparatus and reported to the interruption apparatus which thereupon interrupts the drive system. Drive systems which are designed in this way are suitable for use in equipment, for example, in civil engineering, where emptying of the fuel tank frequently occurs as a result of the extreme building-site operation.
