ABSTRACT:
The internally axed single-rotation machine has inlet and outlet channels , 6), which extend arcuately round the circular cylindrical housing space (11) enclosing the rotors (1, 2) to such an extent that the tangentially connecting inlet and outlet connections (12, 13) cross and the outlet channel (6) extends over part of the inlet channel (5). In the vicinity of this approach between the outlet and inlet channels (6, 5) there is a flow connection (19), which continues the arcuate shape of the outlet channel (6) to that of the inlet channel (5). The gas pressure in the outlet channel (6) is variable by a control element (20) located in said flow connection (19). The single-rotation machine pressure control is associated with minimum noise generation and minimum flow losses and a particularly compact construction is obtained.
