A simplified arrangement for the translation of movement as, for example, arcuate movement as from a lever into movement which is different as for example, in a linear direction with a slide element preferably comprising a piston in a piston pump. In accordance with a preferred aspect, the present invention provides a bridging element which is disposed intermediate a pivoting lever and a linearly sliding slide element with the bridging member being retained in engagement with camming surfaces having an arcuate portion at a constant distance from the pivot axis of the lever and tangentially merging into a linear portion which is parallel to a longitudinal axis along which the slide element is slidable. The bridging member is slidable relative to the camming surface with the bridging member deforming to assume the shape of the camming surface where the bridge member engages the camming surface. Movement of the lever about the pivot axis moves a first end of the bridge member in an arcuate path where it engages the arcuate portion of the camming surfaces and moves a second end of the bridging member connected to the slide element in a linear direction along the linear portion of the camming surfaces. |
