Abstract[English]
A mechanical system with a piston mechanism is designed for compressing working fluid in either a gaseous or liquid state. The system includes a cylinder-piston group, a piston rod, a roller or sliding element, and a rotor with a shaft. The rotor features at least two circular profiles along its circumference, inclined at specific angles. The roller or sliding element, connected to the piston rod, interacts with these profiles. As the rotor rotates, the inclined profiles move the roller or sliding element, which then converts the rotor's circular motion into linear piston movement within the cylinder. The rotor is connected to a drive motor via its shaft. The length of the piston stroke depends on the angle of inclination and the length of the circular arc of the profile intended for compressing the fluid.A special calculation of regressions determines the design of the circular profiles on the rotor, their inclinations and the length of the corresponding circular arcs, as well as the mechanical advantages (M.A.) applied in this mechanical system.[French]
Un système mécanique avec un mécanisme de piston est conçu pour comprimer un fluide de travail dans un état gazeux ou liquide. Le système comprend un groupe cylindre-piston, une tige de piston, un rouleau ou un élément coulissant, et un rotor doté d'un arbre. Le rotor présente au moins deux profils circulaires le long de sa circonférence, inclinés selon des angles spécifiques. Le rouleau ou élément coulissant, relié à la tige de piston, interagit avec ces profils. Lorsque le rotor tourne, les profils inclinés déplacent le rouleau ou l'élément coulissant, qui convertit ensuite le mouvement circulaire du rotor en un mouvement de piston linéaire à l'intérieur du cylindre. Le rotor est relié à un moteur d'entraînement par l'intermédiaire de son arbre. La longueur de la course du piston dépend de l'angle d'inclinaison et la longueur de l'arc de cercle du profil destiné à comprimer le fluide. Un calcul spécial des régressions détermine la conception des profils circulaires sur le rotor, leurs inclinaisons et la longueur des arcs de cercle correspondants, ainsi que les avantages mécaniques (M.A.) appliqués dans ce système mécanique.
