Abstract: The invention relates to a material feed receptacle for a thick matter pump comprising a receptacle lower part and a receptacle top that is detachably connected to the receptacle lower part, a two-part front wall, a rear wall, two two-part lateral walls, an upwardly pointing material feed opening delimited by a peripheral edge, and a pipe junction, which is situated inside the receptacle, can, on the entry side, swivel in an alternating manner in front of the delivery cylinder openings and which, on the output side, leads to a pressure pipe. The invention provides that the receptacle top has an upper lateral wall part and upper lateral wall parts, which have free ends and which extend away from the front wall part. The invention also provides that the peripheral edge has a first edge part, which forms an upper edge of the receptacle top, and ha a second edge part on the receptacle lower part, which is situated on the rear wall and is joined to the first edge part.

Abstract: A feeding reservoir for a two-cylinder pump is provided for the pressurized delivery of thick matter. The feeding reservoir includes a material supply port, a front wall having two pump-side ports therein, and a back wall opposite the front wall having two outlet-side ports therein. The pump-side ports lead to the delivery cylinders of the pump, and the outlet-side ports lead to delivery lines. The outlet-side ports are each positioned diametrically opposite to a respective pump-side port, forming two port pairs. A swing pipe is positioned in the reservoir capable of swivelling alternately between one port pair to the other port pair to place the outlet-side port of a port pair in communication with the pump-side port of the port pair. The swing pipe is a straight through-way pipe. Self-adjusting sealing and wearing rings are positioned between the ends of the swing pipe and the pump-side and outlet-side ports for being pressed against the ports under delivery pressure.

Abstract: An apparatus for conveying thick matter is provided including a delivery line, a thick matter pump connected to the delivery line for conveying thick matter from the pump through the delivery line in an output direction, and a restraining member positioned in the delivery line. The restraining member includes a first group of finger lamellae that are radially arranged and have openings therebetween. Each of the finger lamellae of the first group includes an end secured on the inner surface of the delivery line and an unattached end extending diagonally in the output direction and toward the inside of the delivery line. The finger lamella thereby define a pass-through opening therein for enabling flow of thick matter through the restraining member such that the pass-through opening increases in size when thick matter flows in the output direction and decreases in size when there is no flow of thick matter or when thick matter moves in a direction opposite to the output direction.
