Abstract
The S-shaped pipe section has one end rotatably connected with the distributor or transport pipe. It is rotatable about the centre line of this pipe. The other end connects with that cylinder which delivers concrete during the suction stroke of the other cylinder. Means are provided to swivel the S-shaped section from one to the other position and means to force this section on to its connecting seat with an axial force which differs during the delivery and the swivel phases. The swivel motion may be achieved by hydraulic cylinders or screwed spindles. The seats may be provided with a plate to absorb the wear. The axial force may be provided by an hydraulic cylinder. The swivel cylinders, seating cylinder and pump may be driven from a common hydraulic circuit.
