ABSTRACT:
A multi cylinder, rotary valve, hot gas or fluid powered motor. An inner y having an output shaft, a plurality of cylindrical chambers, a corresponding plurality of sliding pistons, one within each chamber, and a pivot plate for supplying a reaction force to the pistons are mounted for rotation within a housing. A rod, attached within the housing, guides pressurized gas to the inner body through a rotary valve to supply the pressurized gas sequentially to the cylindrical chambers. Gas pressure on the piston and piston force against an angled pivot plate creates uncountered reaction forces tending to rotate the pivot plate and inner body. An output shaft attached to the inner body rotates to produce useful work.
