摘要： The aim is to improve a compressor comprising the following elements: a helical compressor with a first compressor element and a second compressor element whose helical ribs in the form of circle involutes engage with one another and can move relative to one another in an orbital movement about an axis, a medium to be compressed being taken in on the inlet side, successively compressed in chambers formed between the compressor elements and discharged on the outlet side; a drive motor; and a cam driven by the drive motor for producing the orbital motion of one of the compressor elements, a radial and an axial sealing force being generated between the compressor elements. The improvement is such as to maximise the isentropic total efficiency. To achieve this, it is proposed that a sealing force-generating unit producing the radial sealing force relative to the axis should be provided between the cam and orbiting compressor element, its pressure chamber acted on by a pressurised medium kept under a pressure which is proportional to the outlet-side pressure of the medium to be compressed.

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.
