       4 . The motor/pump aggregate according to  claim 1 , wherein the damping bearing comprises several damping elements ( 26 ,  28 ) disposed between the motor/pump unit ( 14 ) and the outer housing ( 12 ).  
   
   
       5 . The motor/pump aggregate according to  claim 4 , wherein the damping elements ( 26 ,  28 ) are constructed as plastic ribs.  
   
   
       6 . The motor/pump aggregate according to  claim 5 , wherein the plastic ribs are vulcanized to a sheet metal ring ( 30 ), which is shrunk onto a connecting plate ( 32 ) on which the motor unit ( 16 ) and the pump unit ( 18 ) are fastened.  
   
   
       7 . The motor/pump aggregate according to  claim 3 , wherein the damping bearing comprises several damping elements ( 26 ,  28 ), disposed between the motor/pump unit ( 14 ) and the outer housing ( 12 ), constructed as plastic ribs and the plastic ribs being vulcanized to the fastening ring ( 24 ).  
   
   
       8 . The motor/pump aggregate according to  claim 7 , wherein the plastic ribs are vulcanized to a sheet metal ring ( 30 ), which is shrunk onto a connecting plate ( 32 ) on which the motor unit ( 16 ) and the pump unit ( 18 ) are fastened.  
   
   
       9 . The motor/pump aggregate according to claims  4 , wherein the damping elements ( 26 ,  28 ) are substantially of parallelpiped shape.  
   
   
       10 . The motor/pump aggregate according to  claim 9 , wherein with respect to a longitudinal axis A of the motor/pump aggregate ( 10 ), which defines a vertical direction, at least one damping element ( 26 ) is aligned vertically.  
   
   
       11 . The motor/pump aggregate according to  claim 9 , wherein with respect to a longitudinal axis A of the motor/pump aggregate ( 10 ), which defines a vertical direction, at least one damping element ( 28 ) is aligned horizontally.  
   
   
       12 . The motor/pump aggregate according to claims  9 , wherein the damping elements ( 26 ,  28 ) have different orientations.  
   
   
       13 . The motor/pump aggregate according to  claim 12 , wherein at least two damping elements ( 26 ,  28 ) are provided, which are aligned substantially perpendicularly to each other.
