Abstract
An improved method and means for increasing the efficiency and power output of combustion engines, fluid power devices and other force transmitting applications. Pressure wave inversion details are provided to increase fluid flow and applied force while reducing friction and wear. The speed of combustion is also significantly increased which improves fuel economy, emissions and engine performance.
Claims20
An internal combustion engine comprising:
- a linearly translating piston having a crown translating along an axis within a combustion chamber;
- a plurality of circular depressions incorporated into said crown of said piston of said internal combustion engine;
- wherein each of said plurality of depressions incorporated into said crown of said piston comprise a substantially curved, concave profile with an upwardly extending sharpened projection at a center of each depression providing a geometric ability to permit downward initial pressure contacting a lower surface of the depression to flow inward and converge at the upwardly extending sharpened projection to return pressure upward along the axis as higher speed inverted pressure;
- and
- wherein said substantially curved profile with said upwardly extending sharpened projection further provides said higher speed inverted pressure and an increase in surface area thereby increasing applied force to said crown of said piston.

A performance improvement to the combustion process of an internal combustion engine having a translating piston translating along an axis comprising:
- a plurality of circular depressions incorporated into a crown of said translating piston of said internal combustion engine;
- wherein each of said plurality of depressions incorporated into said crown of said piston comprise a substantially curved, concave profile with an upwardly extending sharpened projection at a center of each depression providing a geometric ability to permit downward initial pressure contacting a lower surface of the depression to flow inward and converge at the upwardly extending sharpened projection to return pressure upward along the axis as higher speed inverted pressure;
- and
- wherein said substantially curved profile with said upwardly extending sharpened projection inverts pressure flow and further provides an increase in surface area thereby providing a means to increase applied force to said crown of said piston.

A method of improved efficiency in a reciprocating or linear device translating along an axis comprising:
- providing a plurality of circular depressions incorporated into a crown of a piston of said reciprocating or linear device;
- wherein said plurality of depressions incorporated into said crown of said piston comprise a substantially curved, concave profile and an upwardly extending sharpened projection at a center of each depression providing a geometric ability to permit downward initial pressure contacting a lower concave surface of each depression to flow inward and converge at said upwardly extending sharpened projection to return condensed pressure upward along said axis as higher speed inverted pressure;
- and
- translating the piston along the axis to increase pressure flow and applied force thereby increasing the efficiency of said reciprocating or linear device.

A method of improving efficiency and wear reduction in a fluid power device comprising:
- providing a plurality of circular depressions incorporated into a surface of a moving part of said fluid power device moving along an axis;
- wherein said plurality of depressions incorporated into said crown of said piston comprise a substantially curved, concave profile and an upwardly extending sharpened projection at a center of each depression providing a geometric ability to permit downward initial pressure contacting a lower concave surface of each depression to flow inward and converge at said upwardly extending sharpened projection to return condensed pressure upward along said axis as higher speed inverted pressure;
- and wherein said substantially curved profile further traps fluid within said plurality of depressions within said surface of said moving part to provide a protective layer of friction reducing fluid thereby providing increased performance of said moving part and further providing a protective layer of trapped fluid that reduces friction to improve efficiency and reduce wear in said fluid power device.
