Title: Hollow shaft of rotary compressor - has slot grooves for plate pairs driving shaft and sealing gas against back flow
Inventor: HEES ADRIAN VAN
IPC: F04C18/352
Filed: 1977-11-28
Abstract: The rotary compressor is equipped with a central shaft (1) with four or more rigid blades running contactless in a housing bore, and which have a drive shaft.
