Patent ID: 8608458

Claim:
A pump assembly comprising a pump housing ( 2 ) having a pump having a fluid entry ( 6 ) and a fluid exit ( 8 ) for a fluid to be delivered, and a stator housing ( 4 ) having a motor connected to the pump housing ( 2 ), at least one cooling channel ( 12 ) being formed in a wall of the stator housing ( 4 ) and being connected to cooling channels ( 22 , 24 ) in the pump housing ( 2 ), which are in connection with the fluid entry ( 6 ) and the fluid exit ( 8 ), so that the fluid flows through the at least one cooling channel ( 12 ) on account of a pressure difference between the fluid entry ( 6 ) and the fluid exit ( 8 ), wherein one of the stator housing ( 4 ) and the pump housing ( 2 ) includes a first flange ( 14 ) and one of the stator housing ( 4 ) and the pump housing ( 2 ) includes a second flange ( 20 ), via which the pump housing ( 2 ) and the stator housing are connected to one another, wherein the cooling channels ( 22 , 24 ) of the pump housing ( 2 ) and the at least one cooling channel ( 12 ) of the stator housing ( 4 ) in each case run out in connection openings ( 16 , 18 , 36 ) in the associated flange ( 14 , 20 ), and the connection openings ( 16 , 18 , 36 ) in the two flanges ( 14 , 20 ) lie opposite one another in a manner such that the cooling channels ( 12 , 22 , 24 ) of the stator housing ( 4 ) and the pump housing ( 2 ) are connected to one another, wherein at least two of the connection openings ( 36 ) are provided in one of the first and the second flange ( 14 , 20 ), which are connected to a same end of an adjacent cooling channel ( 22 , 24 ), and are arranged in the flange ( 20 ) at different angular positions, in a manner such that the stator housing ( 4 ) is connectable to the pump housing ( 2 ) in at least two different angular positions, in which in each case at least one of the connection openings ( 16 , 18 , 36 ) of the first and of the second flange lie opposite one another.
