Energy roller turbine and=or roller compressor or pump

摘要

The blade (25) is fastened to a disc (18'), which is considerably narrower than the roller (17). At least one stator disc (29) is located next to the narrow disc. The stator has a concave hollow (30) in the contact area, and the roller projects into the hollow with its outer section. The stator is located on the housing (8'). The output (28) of the compressor (2) has an associated return valve (31) and/or return element. This is formed as a nozzle.
