Title (EN) VACUUM PUMP HAVING A SILENCER
(FR) POMPE À VIDE AVEC INSONORISATION
(DE) VAKUUMPUMPE MIT SCHALLDÄMPFUNG
Abstract:
(EN) The invention relates to a vacuum pump which comprises rotor elements (44) in a suction chamber (22). An outlet channel (30) is connected to an exhaust pipe (58). For the purposes of silencing, sound expansion spaces (44) are provided in the outlet channel, which are integrated into the pump housing (10, 36). Alternatively or in addition to these sound expansion spaces, sound expansion spaces may be provided in an inlet channel (32) which is used for the inlet of gas ballast, said sound expansion spaces being preferably likewise integrated into the pump housing (36).
(FR) L'invention concerne une pompe à vide comprenant des éléments de rotor (44) disposés dans une chambre d'aspiration (22). Un canal de sortie (30) est relié à un échappement (58). Pour l'insonorisation, des espaces d'extension sonore (44) sont situés dans le canal de sortie, lesquels sont intégrés dans le boîtier de pompe (10, 36). Alternativement ou en supplément desdits espaces d'expansion sonore, des espaces d'expansion sonore peuvent être situés dans un canal d'entrée (32) qui sert à l'entrée des échappements gazeux, qui sont de préférence également intégrés dans le boîtier de pompe (36).
(DE) Eine Vakuumpumpe weist in einem Schöpfraum (22) angeordnete Rotorelemente (44) auf. Ein Auslasskanal (30) ist mit einem Auspuff (58) verbunden. Zur Schalldämpfung sind im Auslasskanal Schall-Expansionsräume (44) vorgesehen, die in das Pumpengehäuse (10, 36) integriert sind. Alternativ oder zusätzlich zu diesen Schall-Expansionsräumen können in einem Einlasskanal (32) der zum Einlass von Gasbalast dient Schall-Expansionsräume vorgesehen sein, die vorzugsweise ebenfalls in das Pumpengehäuse (36) integriert sind.
