Abstract: A circuit arrangement for operating a linear exhaust-gas probe has a measuring cell for measuring a gas concentration by determining a measuring-cell voltage, in addition to a pump cell for pumping gas. A comparator circuit compares the measuring-cell voltage with a target voltage and provides a corresponding analog deviation signal. A pump current source provides the pump current is controlled by the deviation signal using a control circuit for the approximation of the measuring cell voltage to the target voltage. In order to reliably limit the pump voltage with no significant detrimental effect on the operation, the circuit also comprises: a second comparator circuit for comparing the pump voltage with a predefined threshold voltage and for providing a corresponding binary switching signal; and a counter coupling path between the output of the pump current source and the control circuit, the path being enabled when the threshold voltage is exceeded.

Abstract: A device for transmitting a displacement of an actuator to a setting element comprises two pistons that delimit two transmission chambers and a compensation chamber with a housing. The compensation chamber is hydraulically connected to the two transmission chambers. The transmission chambers transmit a displacement of the first piston in order to effect a displacement of the second piston. The compensation chamber serves as a reservoir for the transmission medium with which the transmission chambers are filled. The compensation chamber is delimited by an elastomer ring. The elastomer ring depicts a simple and economical realization with which it is possible to subject the compensation chamber to the action of pressure and to change the volume of the compensation chamber at the same time. In a preferred embodiment, the elastomer ring is externally subjected to the action of a tension force via a pressure ring.

The distance (H) is measured to a reference measure (x) between a projecting end piece (E) of the touch probe (5) and a reference mark (B) outside of the punch (4). The stamping process is stopped once the reference measure (x) has been obtained.
