Abstract

1. A slush pump, in particular a concrete pump, with several alternating delivery cylinders, with each of which a three-way valve (12, 13) is associated for controlling the flow between supply tank, delivery cylinder (5, 6) and delivery line (11), and with a combinational shift connecting the drives of the delivery cylinders (5, 6) and of the three-way valves (12, 13), which shifts the drive of the delivery cylinder (5 or 6) between the latter's suction and delivery strokes to a compression stroke, whereupon the discharge into the delivery line (11) is obstructed, characterised in that the three-way valves (12, 13) for controlling the flow between supply tank, delivery cylinders (5, 6) and delivery line (11) feature swivelling pipes (14, 15) known per se, to each of which a sliding plate (29, 30) is secured which in the central position of the swivelling pipes covers delivery cylinder openings (22, 23), and in that the intake openings (14a and 15a) of the swivelling pipes (14, 15) are sealed on the wall (3) of the valve housing (1) in the suction position.
