More Information
Summary:The assembly has an electric motor that drives a pump, which is provided as double diaphragm pump with two operating membranes (4). The operating membranes are respectively fixed between a pump housing (5) and a working-space cover (6). An outlet channel (13) is arranged in the working-space cover and the pump housing, such that air expelled from a working-space is directed into an inner space (28) of the pump housing. An air outlet unit is provided to enable a low-noise expelling of the air from the inner space. Die Erfindung betrifft ein Motor-Pumpenaggregat 1, umfassend eine Pumpe 2 und einen die Pumpe 2 antreibenden elektrischen Motor 3, wobei die Pumpe wenigstens einen Arbeitsraum 7 aufweist, welchem (Arbeitsraum 7) jeweils ein Einlasskanal 11 mit Einlassventil 12 und ein Auslasskanal 13 mit Auslassventil 14 zugeordnet sind, wobei die Pumpe einen Schalldämpfer 15 aufweist. Um ein verbessertes Motor-Pumpenaggregat bereitzustellen, welches bei unverminderter Pumpenleistung und langer Lebensdauer den Anforderungen in Bezug auf den akustischen Komfort Rechnung trägt, wird erfindungsgemäß vorgeschlagen, dass die Pumpe 2 ein drittes Ventil 16 aufweist, welches zur Schalldämpfung vorgesehen ist.
