Abstract:
A rotary apparatus able to produce mechanical energy from pressurized fluids flow like hydraulic, steam, pneumatic, and internal combustion, or to pump, vacuum and compress, comprising:A housing having an internal contour wall, including two planar side covers;Four pivoting blades consecutively pivoted one to the other at their ends about parallel axes;Four carriages external to, and pivoted on the ends of said pivoting blades, and carrying end parts in contact with said housing contour wall;The assembly of said four pivoting blades and four carriages forming a four degrees of freedom X, Y, .theta., .PHI. variable-shape rotor rolling inside said housing contour wall about a central axis;Said rotor carrying filler tips;A system of lateral seals in contact with the said side covers and a set of contour seals in contact with the said housing contour wall;Four chambers of variable volume, each limited by two successive said contour seals, and extending in-between the said contour seals along the contour wall, and on the outward face of the said carriages, pivoting blade and filler tip;A set of ports in the said housing and side covers for intakes and exhausts;Wherein all consecutive compressions are occurring repetitively in the same housing areas, and all consecutive expansion are also occurring repetitively at a different intermediate housing areas;Wherein the two compression housing areas are opposed, and alternate with the two as well opposed expansion housing areas;Wherein successive compression strokes and expansion strokes start and end simultaneously;Wherein the distance between two consecutive said contour seals increases and decreases during a revolution of the said rotor, such as to generate a geometric volume pressure enhancement.
