ROTARY POSITIVE-DISPLACEMENT FLUID MACHINE.

摘要

A rotary machine has a rotor (450) eccentrically mounted in a casing and having a plurality of vanes (206) connected to oscillating arms (209) via cranks (208), the cranks having elements (400, 401) pivotally embracing a radial outer end of arm (209). The arms (209) can be radial. The rotor (450) has outer axial parts (457, 458) connected to intermediate part (450) by grooves (453) and rings (452) resisting radial expansion. The rotary machine can be used in a fuel-injected engine for example to derive energy from the difference in air pressure between ambient and the inlet manifold.
