Title (EN) ADAPTIVE MOTOR MECHANISM
(FR) MECANISME DE MOTEUR ADAPTATIF
Abstract:
(EN) The present invention relates to an adaptive motor mechanism which achieves the transformation of the alternative motion of translation in rotation motion and conversely, concomitantly with the continuous adjustment of the stroke. This mechanism has two pistons (1) which drive, using two connecting rods (3), a crank shaft (4) which turns inside a main shaft (6). The crank shaft (6) includes a satelitte (c) which engages with an interior geared plate (5), considered fixed for the same adjustment. The interior geared plate (5) has to the external side a geared segment (f) engaging with a worm (8) which can change the radial position of the interior geared plate (5) and therefore the stroke of the pistons (1). This mechanism can be used for thermic and hydraulic machines or for any mechanical structure having need of variable stroke.
(FR) Cette invention concerne un mécanisme de moteur adaptatif permettant d'effectuer la conversion d'un mouvement alternatif en translation en un mouvement rotatif, et inversement, ceci tout assurant un ajustement continu du cycle. Ce mécanisme comprend deux pistons (1) entraînant par des bielles (3) un vilebrequin (4) qui tourne à l'intérieur d'un arbre principal (6). Cet arbre principal (6) comprend un satellite (c) entrant en contact avec un plateau (5) denté sur son intérieur et considéré comme fixe en vue de cet ajustement. Ce plateau (5) denté sur son intérieur possède, sur son côté externe, un segment denté (f) entrant en contact avec une vis (8), laquelle permet de modifier la position radiale dudit plateau (5), ainsi que le cycle des pistons (1). Ce mécanisme peut être utilisé dans des machines thermiques et hydrauliques, ou encore dans toute structure mécanique faisant appel à un cycle variable.
