Abstract:
Meter, comprising four disk units (1, 2, 3, 4) which are arranged in parallel to each other, the centers of which are located on an axis extending perpendicularly to the planes of the four disk units (1, 2, 3, 4), and a first disk unit (1) of which has first receiving means (1a) for taking up a force effecting a rotation of the first disk unit around the axis and first transmission means for transmitting the rotation onto a second disk unit (2) which has second receiving means for taking up a force transmitted by the first transmission means and effecting a rotation of the second disk unit (2) around the axis, and a spring cam (6) which is arranged elastically at the outer contour of the second disk unit (2) for the transmission of the rotation onto a fourth disk unit (4) which has an internal toothing (13) for taking up a force transmitted by the spring cam (6, 6a) and effecting a rotation of the fourth disk unit (4) around the axis, wherein at the outer contour of a third disk unit (3) at least one projecting part (11) is provided which in a predetermined rotational position of the second disk unit (2) relative to the third disk unit (3) deviates the spring cam (6) in radial direction, so that the spring cam (6) comes into engagement with the internal toothing (13) of the fourth disk unit (4) and wherein at least one tooth of the internal toothing (13) of the fourth disk unit (4) is filled up in order to lead to a locking effect.
