Abstract:
A rotary central-axis unidirectional av converter for engines and pumps comprising:a base member (10); an operating shaft (OS) including a crankarm; a first rotor concentric with said operating shaft including a first vane carrier (V1) with first vanes and a first side gear (27); a second rotor concentric with said operating shaft including a second vane carrier (V2) with second vanes and a second side gear (28); a round main pressure chamber divided into revolving variable volume subchambers between said first and second vanes; a limited angle bevel-gear-type differential gear with its reversing gear (29) rotatably mounted to said crankarm and said reversing gear being in mesh with said first and second side gears; a crankpin (38) on said reversing gear forced to follow a peristaltic control wave which is causing said first and second rotors to alternately accelerate and decelerate for changing the volumes in said subchambers between said vanes while said vanes are in a variable speed rotary motion and a distributing stator with a communication hole pattern having a synchronized relationship with said first and second vanes to effect a fluid flow and energy conversion between a fluid pressure and a powered rotation when said vanes are in motion.
