Abstract

Improvements in concrete pumps and the like, with two cylinders and pistons driven in opposite directions, which suck the medium to be pumped from a reserve container and transport it to a pressure line, with a distributor slide arrangement for both cylinders for communication alternative of the reserve container with one of the cylinders and the other cylinder with the pressure line and vice versa, and with an arrangement for the assembly of the means to be pumped transported by the two arrangements of cylinder and piston, characterized in that the arrangement sliding valve is structured as a tilting tube, in that one end of the tilting tube faces in the compression position in each case the end of the corresponding cylinder, while the other end of the tilting tube is always associated with the beginning of a of the pressure lines.
