Multiple-flow vane cell pump

Abstract

A multiple-flow vane cell pump which includes at least two points (openings) along the rotational direction of the rotor, at which there is essentially the same pressure during operation and which are spaced apart from inlets and outlets and are hydraulically connected to each other (connection).

1 .- 10 . (canceled) 
     
     
         11 . A multiple-flow vane cell pump comprising:
 a plurality of spaced apart inlets;   a plurality of spaced apart outlets;   a rotor including at least two openings formed along a rotational direction of the rotor,
 wherein at the openings there is essentially a same pressure during operation and the at least two openings are spaced apart from the inlets and the outlets, and wherein the at least two openings are hydraulically connected to each other by at least one connection. 
   
     
     
         12 . The multiple-flow vane cell pump according to  claim 11 , wherein the at least two openings are bores or grooves in one of the rotor, a stroke ring, or at least one side plate. 
     
     
         13 . The multiple-flow vane cell pump according to  claim 12 , wherein the at least two openings are a same distance from an axis of the rotor. 
     
     
         14 . The multiple-flow vane cell pump according to  claim 12 , wherein at least one of the bores or the grooves extends radially and/or at least one of the at least two openings is formed axially. 
     
     
         15 . The multiple-flow vane cell pump according to  claim 14 , wherein at least one of the at least one bores, the grooves and the at least two openings is formed in a linear manner. 
     
     
         16 . The multiple-flow vane cell pump according  claim 11 , wherein the at least one connection extends at least partially in a circumferential direction. 
     
     
         17 . The multiple-flow vane cell pump according to  claim 11 , wherein the at least one connection surrounds a pin. 
     
     
         18 . The multiple-flow vane cell pump according to  claim 11 , wherein at least one side plate is closed by a lid. 
     
     
         19 . The multiple-flow vane cell pump according to  claim 11 , wherein the pump further comprises a pot-shaped housing. 
     
     
         20 . The multiple-flow vane cell pump according to  claim 11 , wherein the at least one connection is produced by an additive manufacturing method.
