System for the circulatory conveyance of media

Abstract

The invention relates to a system for the circulatory conveyance of media, with a drive and with two conveying chambers, the first conveying chamber constituting a feed chamber and the second conveying chamber a return chamber.

1 . A system for the circulatory conveyance of media, with two conveying chambers and with a common drive ( 1 ), wherein the first conveying chamber constitutes a feed chamber ( 4 ) and the second conveying chamber a return chamber ( 3 ).  
     
     
         2 . The system as claimed in  claim 1 , defined by a double-diaphragm pump.  
     
     
         3 . The system as claimed in  claim 1  or  2 , defined by a pulsation damper  
     
     
         4 . The system as claimed in  claim 3 , wherein the pulsation damper ( 5 ) is integrated into the feed chamber ( 4 ).  
     
     
         5 . The system as claimed in one of  claims 1  to  4 , defined by a needle valve ( 10 ).  
     
     
         6 . The system as claimed in one of  claims 1  to  5 , wherein at least one line connection is arranged perpendicularly to the feed chamber ( 4 ) and/or return chamber ( 3 ).  
     
     
         7 . The system as claimed in one of  claims 1  to  6 , defined by polyethylene housing parts of the drive ( 1 ) and/or of the conveying chambers ( 3 , 4 ).  
     
     
         8 . The system as claimed in one of  claims 1  to  7 , defined by a reservoir ( 13 ).  
     
     
         9 . The system as claimed in one of  claims 1  to  8 , defined by a four-way valve ( 12 ).  
     
     
         10 . The system as claimed in  claim 9 , wherein the four-way valve ( 12 ) is designed as a disk valve.  
     
     
         11 . A use of a system as claimed in one of  claims 1  to  10  for the conveyance of media along a circulatory path between a first and a second container.  
     
     
         12 . A use of a system as claimed in one of  claims 1  to  10  for regulating the filling-level height in a doctor blade chamber.  
     
     
         13 . A use of a system as claimed in  claim 9  or  10  for emptying a first and a second container.  
     
     
         14 . A method for conveying a medium from a first container into a second container, with the following steps: 
 operating a pump assembly with a feed chamber and with a discharge chamber by means of a common drive;    sucking the medium out of the first container into a feed chamber;    discharging the medium from the feed chamber into the second container;    sucking the medium out of the second container into a return chamber, and    discharging the medium from the return chamber into the first container.    
     
     
         15 . The method as claimed in  claim 14 , defined by a pulsation damping of the medium.
