摘要： In order to improve a screw-type compressor designed for compressing a working medium, comprising an outer housing, two screw rotors disposed in the outer housing in corresponding bores and a drive for the screw rotors in such a way that the sealing gap undergoes as little variations as possible, the invention provides that a compressor screw housing is mounted inside the outer housing in which the bores for the screw rotors are disposed and an intermediate space is disposed between a substantial part of the compressor screw housing and the outer housing.

摘要： The invention concerns improvements to a method for producing cast-iron parts with a section having an outer contour which is helically symmetrical to an axis of symmetry such that these parts can be more simply produced and hence more economically. According to the invention, a pattern (84) comprising the section (16) with a helically symmetrical outer contour is shaped so as to produce a casting mould body (50) which surrounds this section azimuthally to the axis of symmetry and in an enclosed manner, and a casting (10), which corresponds to the part to be manufactured, is produced with this casting mould body (50) in a casting mould (44) by tempering which leads to solidification of the cast-iron melt shell.

摘要： The invention relates to a refrigeration compressor that comprises an integral housing, an electric motor housed in said integral housing and comprising a stator and a rotor sitting on a drive shaft, a screw compressor, disposed in said integral housing, whose compressor screw sits on the drive shaft that is rotatably mounted in the integral housing by a first radial bearing between the rotor and the compressor screw, and a second radial bearing disposed on the side of the compressor screw opposite the first radial bearing. The aim of the invention is to improve said compressor in such a way as to eliminate the risk of the rotor touching the stator. To this end, the drive shaft is mounted in the integral housing on a third radial bearing which is disposed on the side of the rotor opposite the first radial bearing. A drive section of the drive shaft that extends between the first radial bearing and the third radial bearing is further adapted to compensate for any alignment errors between the three radial bearings.
