Abstract
The invention concerns an arrangement for conveying thick matter, in particular liquid concrete. The arrangement comprises a pump (12) which is to be charged on the input side with thick matter to be conveyed, and a distributor (10) which can be connected via a high-pressure feed line (20) to the pressure joint (30) of the pump (12) and preferably takes the form of a tunnel shuttering distributor. The high-pressure feed line (20) is connected both on the pump side and the distributor side to a pipe-switching device (22, 24) which can in each case be switched alternatively between two connections (26, 32, 40, 44). The pump-side pipe-switching device (22) is connected at its one connection (26) to the pressure joint (30) of the pump (12) and at its other connection (32) to the pressure joint (36) of a pressure medium pump (16) which can be acted upon by low-viscosity pressure medium via a reservoir (18). The distributor-side pipe-switching device (24) is connected by one of its connections (40) to the distributor (10) an by its other connection (44) via a return line (45) to the reservoir (18) of the pressure medium pump (16). In order to prevent the distributor side form being acted…
