Device for producing and downward movement with at least one element

摘要

The system has at least one element (3,8) setting a determined distance between two surface regions of two parts (1,2) which face opposite each other. The element is moved along the two opposing surfaces. The up and down movements result from the curve shapes of the surfaces of the parts (1,2) opposite each other. Both parts are fixed against each other, and the element is rotated from a shaft (7) with a determined radius (6). The shaft extends in the direction of the upward and downward movement, and by a rotation of the parts against each other, the amplitude of the movement is adjustable. The curve shapes of the parts are identical, and sinusoidal.
