Abstract
An axial bevel gear generated control motion is used to control an accelerating-decelerating vane motion in a cylindrical central axis main pressure chamber using a limited angle differential gear whose reversing gear is receiving an axial crank controlled motion from an orbiting bevel gear or in a modified version from an oscillation controlling barrel cam. Same bevel gear crank generated axial motion is also used to provide an axial piston motion in cylinders with one or more pistons which can be in a stationary or rotating cylinder housing. In all the different models a valveless port communication with a radial or axial flow distribution control is used for a pressurized fluid flow which is suited to external pressure or internal combustion engines where the energy conversion is from a fluid or combustion pressure to a powered output shaft rotation or in a reverse energy conversion mode, the central shaft is functioning as a power input shaft for pumping or gas compressor applications. For different vane numbers and axial motion generation gear ratios as well as engine or pump types, different communication hole patterns on a distributing stator or rotor are used.
