ABSTRACT:
An electric control device (10) for a flushing system, of the type that includes an axial valve (18) whose shutter (22) is controlled by an axial rod (24) that is capable of being moved radially by a finger (26) actuated by an electric actuating device (32). The electric actuating device (32) includes at least one connecting rod (34) of which a first end (36) is articulated by a pivot (38) to the second end of the finger (26) and of which the second end (44) is articulated by a pivot (40) on an eccentric (42) moved by an electric motor (46), in order to generate a back-and-forth movement of the first end (28) of the finger (26) actuating the rod (24) of the shutter.
