Abstract
The present invention relates to a pump arrangement (10) having a housing (12) and cover (14). The housing (12) and cover (14) form part of a pump mechanism (16). A first inlet or a housing inlet (26) is formed in the housing (12) and is connected to the pump mechanism (16). A second inlet or a cover inlet (28) is formed in the cover and is connected to the pump mechanism. The cover (14) also has a cover outlet (34) formed in the cover (14) that is connected to the pump mechanism (16) and is where fluid medium such as air flows out of the housing (12) arrangement. The use of two inlets increases the flow efficiency.
