Title
(DE) MIKRO-DRUCKLUFTMOTOR
(EN) COMPRESSED AIR MICROMOTOR
(FR) MICROMOTEUR A AIR COMPRIME
Abstract
(DE)
Ein Mikro-Druckluftmotor weist einen in einem Gehäuse (1 ) drehbar gelagerten Kollektor (6) für die Druckluftzufuhr und -abfuhr zum, bzw. vom Rotor (2) auf. Durch Verdrehen des Kollektors (6) bis in die Endstellungen ist eine Drehrichtungsumkehr sowie eine stufenlose Drehzahlregulierung möglich. In einer Neutralstellung des Kollektors (6) kann zudem der Rotor (2) stillgesetzt und arretiert werden.

(EN)
The invention relates to a compressed air micromotor comprising a collector(6) that is rotatably mounted in a housing (1) for the supply and evacuation of compressed air to or from the rotor (2). The rotation of the collector (6) into its end positions, permits a reversal of the rotational direction and an infinitely variable regulation of the speed. When the collector (6) is in a neutral position, the rotor (2) can be shut down and locked.

(FR)
La présente invention concerne un micromoteur à air comprimé présentant un collecteur (6) monté rotatif dans un boîtier (1), destiné à l'entrée et à la sortie d'air comprimé dans ou du rotor (2). La rotation du collecteur (6) jusqu'aux positions extrêmes rend possible le changement de sens de rotation, ainsi qu'une régulation de vitesse de rotation progressive. Lorsque le collecteur (6) se trouve dans une position neutre, le rotor (2) peut en outre être mis au repos ou arrêté.
