Device for controlling and/or regulating a hydraulically activatable shifting element of a gearing mechanism and a gearing mechanism

[0020]FIG. 1 presents a schematic diagram of a device 1 for controlling and / or regulating a hydraulically operated shifting element 2 of a gearing mechanism (not shown in detail), the element being accommodated in an installation space of the gearing mechanism that is connected with the oil sump of the gearing mechanism. Here the shifting element 2 is placed in relation to the housing of the gearing mechanism in such a way that the shifting element 2 can come into contact with the hydraulic fluid in the oil sump. The shifting element 2 is configured with a piston-cylinder unit 3 that can be acted upon by a hydraulic operating pressure p, and in this example consists of a frictionally-engaged multiple disk clutch of an automatic gearing mechanism for engaging ordisengaging a gear ratio of an automatic gearing mechanism.

[0021] Furthermore, the device 1 shows a control and / or regulator unit 4 and an electric motor 5 that is actuated by it. In addition, there is provision for a drive
