Patent ID: 7703348

Claim:
A device ( 1 ) for at least one of controlling and regulating a hydraulically activatable shifting element ( 2 ) of a gearing mechanism, the device comprising an electric motor ( 5 ) that is actuated at least by a control and regulator unit ( 4 ), which has a drive transformer device ( 6 ) that is functionally connected to the electric motor ( 5 ), a rotational drive of the electric motor ( 5 ) is transformed into a hydraulic operating pressure (p) of the shifting element ( 2 ), the shifting element ( 2 ) is installed in an installation space that is connected to an oil sump of the gearing mechanism, the shifting element ( 2 ) communicates with and is activated by a piston-cylinder unit ( 3 ) and only one fluid connection connects the drive transformer device ( 6 ) with the first piston-cylinder unit ( 3 ).
