Title

(EN) OSCILLATING PISTON ENGINE
(FR) MOTEUR A PISTONS OSCILLANTS
Abstract
(DE)
Eine Schwenkkolbenmaschine (10) weist ein Gehäuse (12) auf, in dem mehrere als zweiarmige Hebel ausgebildete Kolben um jeweils eine zu einer mittigen Gehäuseachse (36) parallele Schwenkachse verschwenkbar angeordnet und gemeinsam in einer Umlaufrichtung beweglich sind. Die Kolben weisen auf ihrer einer Gehäuseinnenwand (14) abgewandten Seite Laufflächen (52, 56) auf, die beim Umlaufen der Kolben in dem Gehäuse (12) entlang zumindest einer Steuerkurve eines mittigen gehäusefesten Kurvenstückes (48) geführt sind, um die Schwenkbewegungen der Kolben beim Umlaufen zu steuern. Die Steuerkurve ist als Innenkontur (50, 54) an dem Kurvenstück (48) ausgebildet, entlang der die Kolben über die Laufflächen (52, 56) fliehkraftseitig abgestützt geführt sind.
(EN)
The invention relates to an oscillating piston engine (10) comprising a housing (12) in which several pistons configured as two-armed levers are arranged such that they are each able to oscillate about an oscillation axis which is parallel to a central housing axis (36) and can together be moved in a direction of rotation. On their sides facing away from an inner wall (14) of the housing the pistons have contact surfaces (52, 56) which when the pistons rotate in the housing (12) are guided along at least one control track of a central cam element (48) which is fixed to the housing so as to control the oscillation of the pistons during rotation. The control track is configured as an inner contour (50, 54) provided on the cam (48) and the pistons are guided along said contour such that, on the centrifugal force side, they are supported on the contact surfaces (52, 56).
(FR)
L'invention concerne un moteur à pistons oscillants (10), comportant un carter (12) dans lequel plusieurs pistons se présentant sous la forme de leviers à deux bras sont logés de façon à osciller autour d'un axe d'oscillation (58) parallèle à l'axe central de carter (36) et peuvent se déplacer en commun dans un sens de rotation. Ces pistons présentent, sur leur côté opposé à une paroi interne de carter (14), des surfaces de contact (52, 56) qui sont guidées, lors de la rotation des pistons dans le carter, le long d'au moins une piste de commande d'une came centrale (48) solidaire du carter pour commander les oscillations des pistons lors de la rotation. Cette piste de commande se présente sous la forme d'un contour intérieur (50, 54) au niveau de la came (48), contour le long duquel les pistons sont guidés de manière à prendre appui, côté force centrifuge, sur les surfaces de contact (52, 56).
