A rotary apparatus producing mechanical energy from hydraulic, steam, and pneumatic pressurized fluid flow, and from Stirling cycle, Brayton cycle, Otto and Diesel internal combustion cycles and to pump, vacuum and compress, generally referred to as a Quasiturbine, and comprising:
- a stator casing having an internal contoured housing wall, including two lateral side covers;
- pivoting blades consecutively pivoted one to the other at their ends, and pivot axes being parallel;
- wherein each of said pivoting blades carrying an inwardly directed power transfer slot;
- an assembly of said pivoting blades and joints forming a X, Y, θ variable-shape rotor rolling inside said internal contoured housing wall about a central axis;
- a method of calculating a family profile of curves for said internal contoured housing wall, and selecting criteria to meet the pressure-volume engine PV diagram;
- each of said lateral side covers carrying an annular track on an inner surface;
- a set of contour seals in contact with said internal contoured housing wall, and a system of lateral seals in contact with said lateral side covers;
- variable volume chambers, each of said variable volume chambers limited by two successive contour seals, and extending along the inner surface of the internal contoured housing wall, and the outer surface of said pivoting blades;
- each of said pivoting blades carrying a combustion chamber cavity;
- a set of ports in said casing for intakes and exhausts;
- a set of ports in said lateral side covers for intakes and exhausts;
- a set of ports through said pivoting blades, connecting said variable volume chamber to the central area;
- an ignition flame transfer slot-cavity;
- a compression ratio tuner;
- a set of clutch centrifuge weights inside a rotor;
- a set of annular power sleeves located inside said rotor;
- a modulated Inner Rotor Volumes (MIRV) within said rotor;
- a set of differential washers linking said annular power sleeves to a power disk and a power shaft;
- wherein all consecutive compressions housing areas are occurring repetitively in the same housing areas, and all consecutive expansions are also occurring repetitively at different intermediate housing areas;
- wherein the two compression housing areas are opposed, and the two opposed expansion housing areas;
- wherein each successive compression stroke and expansion stroke start and end simultaneously;
- wherein the distance between two consecutive contour seals stays almost constant during a revolution of said rotor,
- wherein the contour seals stay almost perpendicular to said internal contoured housing wall at all time;
- wherein said differential washers prevents the wheel-bearings axes rotational harmonic to reach said power shaft;
- wherein said rotor and said differential washers linking centers of mass are immobile during rotation;
- wherein said variable volume chambers are asymmetric from mid-value, and the pressure pulse is short and increases and decreases linearly near the top dead center;
- wherein a Quasiturbine Internal Combustion cycle (QTIC) results from said pressure pulse characteristics;
- wherein said Modulated Inner Rotor Volume (MIRV) is 45 degrees out of phase with outward rotor chambers;
- and
- wherein said Modulated Inner Rotor Volume (MIRV) is alternately pressurized to make an Inward Rotor Engine Quasiturbine IREQ), driving said rotor from the interior;
- wherein the direction of rotation is reversed, reversing the direction of the flow.
