Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR A HELICE
Abstract:
(EN) A mounting location or mass of a balance weight (15) for balancing the inertial force due to the reciprocating motion of an Oldham's ring (12) is determined in such a manner that the vibrations by an unbalanced inertial force of the Oldham's ring are transmitted at angles exactly or nearly perpendicular to a direction of connecting a sealed vessel (1) to an accumulator (2), whereby the vibrations due to the imbalance of the main body of the compressor caused by the balance weight (15) for balancing the inertial force due to the reciprocating motion of the Oldham's ring become large at angles exactly or nearly perpendicular to the direction of connecting the sealed vessel (1) to the accumulator (2), but become small in the above-described direction or at angles close to this direction, with the result that the vibrations of a piping system connected to the accumulator (2) become low, thus reducing the noises from the air conditioner as a whole.
(FR) Un emplacement de fixation ou la masse d'un contre-poids (15) pour contrebalancer la force d'inertie due au mouvement alternatif d'une bague Oldham (12) est déterminé de telle manière que les vibrations consécutives à une force d'inertie non contrebalancée de la bague Oldham sont transmises selon des angles exactement ou presque perpendiculaires à une direction de liaison d'un récipient scellé (1) avec un accumulateur (2). Des vibrations dues au déséquilibre du corps principal du compresseur provoqué par le contrepoids destiné à contrebalancer la force d'inertie due au mouvement alternatif de la bague Oldham, deviennent importantes selon des angles exactement ou presque perpendiculaires à la direction de liaison du récipient scellé (1) avec l'accumulateur (2), mais deviennent faibles dans la direction précitée ou selon des angles proches de cette direction, et il s'en suit que les vibrations d'un système de canalisations relié à l'accumulateur (2) s'affaiblissent, réduisant ainsi le bruit du climatiseur dans son ensemble.
