Abstract
The present invention is directed to a combustion-operated setting device (10) with a combustion chamber (12) for a combustible propellant, an ignition device (16) for generating an ignition spark in the combustion chamber (12), a metering device (13) for metering the propellant, and control electronics (30) for the ignition device (16) and the metering device (13). In order to improve the control electronics (30), the control electronics (30) have at least two logically separated circuits. A first circuit (33) controls the metering device (13) and a second circuit controls the ignition device (16).
Claims5
A combustion-operated setting device, comprising:
- a combustion chamber (12) for a combustible propellant;
- an ignition device (16) for generating an ignition spark in the combustion chamber (12);
- a metering device (13) for metering the propellant;
- and
- control electronics (30) for the ignition device (16) and the metering device (13) having at least two logically separated circuits (33, 34) which can be electrically disconnected from one another, a first circuit (33) controlling the metering device (13) and a second circuit controlling the ignition device (16).
