Abstract: A conveyor having a frame, a piston and cylinder unit operable by means of pressure fluid and secured in the frame, a spring assembly for actuation of the piston, a holder mounted on the frame and reciprocable by means of the piston and cylinder unit and carrying a conveyor path for receiving articles. The piston and cylinder unit has inlet and outlet valves and throttle means at the outlet of the outlet valve. A control rod connected to the piston of the piston and cylinder unit is adapted to allow control of the cross-sectional passage area of the throttle means. The control rod has a back-off section which merges into the full diameter of the rod at one end over a long distance and at the other end over a considerably shorter distance. The conveyor permits moving articles by a throwing movement also along a slightly upwardly inclining conveyor path.
