Rotary Lobe Expander technology

Rotary lobe engines are widely used like air motors for contineous work like winches mining pneumatic engines etc
The performance is related to pressure rather than mass flow (main difference in comparison to turbines screw / scroll solutions
N ear frictionless torque producing motor parts r esulting in long and maintenance free lifetime
C ompletely enclosed motor casing without leakage and integrated shaft seal
C ompact design and freedom of installation
Can accept mixture of liquid and gas ( the system pump creates the pressure

Straight flow through
The small rotor has just a sealing function
The big rotor axis to mechanical power
Because of the pressure difference the lobes turn in oposite direction
Depending on gas properties, (EXPANSION RATIO) adaptation of inlet outlet dimensions (asymetric design)
