摘要

A rotary fluid machine (10) comprising at least two toroidal chambers (11A, 11B) arranged to interpenetrate, each of said chambers containing ports (161, 162, 163, 164) and a rotary piston means (12A) that drives an output shaft (13), the piston means of each chamber being so correlated in their respective movements that they provide working sections in the chambers for the fluid to effect a power drive into said output shaft (13).
