Abstract

A driving arrangement for a pump, especially a liquid metering pump, includes a pump tappet mounted on a support for displacement in and opposite to a predetermined direction during a pumping and a return stroke thereof, respectively. A restoring spring member urges the pump tappet opposite to the predetermined direction. There is further provided a mechanical energy storage device which includes a storage tappet mounted on the support spaced from the pump tappet for displacement in and opposite to the predetermined direction, and an elastically yieldable storage member urging the storage tappet in the predetermined direction. The tappets are alternatingly displaced against the forces exerted thereon by the respective spring and storage members by a motor-driven eccentric member interposed between the tappets and having an outer surface which acts on the pump tappet at least during a predetermined part of each of the strokes to displace the pump tappet against the force of the restoring spring member in the predetermined direction, and on the storage tappet to displace the same opposite to the predetermined direction with attendant storage of mechanical energy in the compressible storage member for transmission of such stored mechanical energy to the pump tappet during subsequent movement of the storage tappet in the predetermined direction.
