Abstract: A rotary piston pump has at least two rotors (8) with associated drive shafts (26), wherein for each rotor (8) an associated bearing tube (28) is provided, which extends into the associated rotor (8) and through which the associated drive shaft (26) passes. Between the inside (24) of each rotor (8) and the outside of the bearing tube (28) a first gap (64) is provided. In operation, the first gap (64) contains cooling fluid and is part of a cooling fluid circuit.

Abstract: The invention relates to a process for producing a region of greater wall thickness in a longitudinal hollow section (1) which, to this end, is subjected to a radial and axial pressure and plastically deformed thereby. The hollow section (1) is secured in a matrix (2) corresponding to the section dimensions which has an enlarged cross section corresponding to the intended final dimensions of the hollow section (1) in the deformation region. The essential embodiment consists in that the deformation to attain an increased wall thickness (14) takes place in a region between the ends of the section. In addition, the wall thickness (19) can be increased at at least one of the ends of the section.

Abstract: The present invention is a novel device and method of shaping an end of a pipe. One end of a pipe is inserted into a shaped die in such a way that the outer surface of the pipe rests against the interior portion of the die. A piston is then inserted into the pipe in such a way that the outer surface of the piston rests against the interior surface of the pipe. The piston is then forcibly driven into the die against the pipe as to forcibly shape the pipe to a predetermined configuration. The present invention also discloses numerous embodiments to shape a pipe.
