Title:
燃料を搬送するためのユニット
Document Type and Number:
Japanese Patent JP2004507666
Kind Code:
A
Abstract:
The unit includes an electric drive motor (12) and a pump section (24) that are situated next to each other in a common housing (10) designed at least nearly in the shape of a hollow cylinder. The pump section (24) comprises a delivery element (26) rotating in a pump chamber (30), and one wall (32, 34) each forms a boundary of the pump chamber (30) with the drive motor (12) and with the outside of the housing (10) in the direction of the axis of rotation (28) of the delivery element (26). The walls (34) forming the boundary of the pump chamber (30) with the outside of the housing (10) is formed as a single component with the housing (10), and the walls (32) forming the boundary of the pump chamber (30) with the drive motor (12) is inserted into the housing (10) as a separate component. Due to the fact that the wall (34) forming the boundary of the pump chamber (30) with the outside is integrated with the housing (10), no separate steps are required to manufacture and assemble said wall and housing, and the pump chamber (30) is sealed off completely from the outside of the housing (10), because no joints are present that would have to be sealed off.
