Abstract: A method for determining a correction value for a regulating device for a regulating valve. The regulating valve regulates a fluid flow through a chamber, and a shut-off element of the regulating valve is placed by the regulating device by an actuator of the regulating valve in mutually different positions relative to a throughflow opening for the fluid flow. An encoder is provided and each position of the shut-off element corresponds to an encoder value. A pressure value, in particular which is representative of the fluid in the chamber, is measured with a pressure sensor in mutually different positions of the shut-off element. The position of the shut-off element at which a maximum of the pressure values is measured is identified by the regulating device as the minimum throughflow position of the shut-off element. The correction is determined from the encoder value at which the minimum throughflow position is identified.

Abstract: A pet feeding device (10) for supplying and opening filled containers (12) has at least one stamp for indenting and/or bending an edge (46) of the container (12). In a method for supplying and opening filled containers an edge of the container is indented and/or bent before opening about at least one substantially horizontal axis.
