  • Patent number: 11306717
    Abstract: A co-rotating scroll machine operable as compressor or expander, comprises a transmission and guidance mechanism for first and second scroll plates, having three transmission and guidance units uniformly distributed around the scroll plates towards the periphery thereof. Each transmission and guidance unit comprises a male element mounted on one of the scroll plates and a facing female element mounted on the facing scroll plate. Each transmission and guidance unit comprises an internal ring mounted for angular displacement in the opening of the female element, the internal ring having therein a slot wherein the male element of the transmission and guidance unit slides. The male of the three transmission and guidance units are supported and guided by respective support elements on a common external guide ring. A liquid injection system comprises a liquid channel which is connected with bleed holes.

  • Patent number: 9604232
    Abstract: A turbine rotor, e.g., for a drive turbine of a rotary atomizer, is disclosed having a rotatably supported turbine shaft with the potential for mounting an atomizer wheel, and having at least one drive turbine wheel having a plurality of turbine blades. The turbine blades of the drive turbine wheel may be impinged on during operation by a drive fluid in order to drive the turbine rotor. The drive turbine wheel may be designed for the drive fluid to axially impinge on the turbine blades. A complete drive turbine having such a turbine rotor is also disclosed, as well as a complete rotary atomizer and individual exemplary components of the drive turbine.
