Device for Supplying Ink to a Printing Press

Abstract

A device for supplying ink to a printing press, includes a piston pump and a hydraulic or pneumatic cylinder driving mechanism which drives the piston rod of the piston pump and the cylinder driving mechanism includes several cylinder chambers, which are separated from one another and each of which contains a driving piston, which can be acted upon with pressure.

1 . A device for supplying ink to a printing press, comprising:
 a piston pump having a piston rod, and   a cylinder driving mechanism which drives the piston rod of the piston pump, the cylinder driving mechanism including several cylinder chambers which are separated from one another and each of which includes a driving piston which can be acted upon with pressure.   
   
   
       2 . A device for supplying ink of  claim 1 , wherein the cylinder driving mechanism comprises at least one tandem cylinder. 
   
   
       3 . A device for supplying ink of  claim 1 , wherein the cylinder driving mechanism comprises at least two parallel cylinder chambers, which are disposed next to one another, each of which includes a driving piston. 
   
   
       4 . A device for supplying ink of  claim 1 , wherein said cylinder driving mechanism is one of:
 a pneumatic cylinder driving mechanism, and   a hydraulic cylinder driving mechanism.   
   
   
       5 . A device for supplying ink of  claim 2 , wherein the cylinder driving mechanism comprises at least two parallel cylinder chambers, which are disposed next to one another, each of which includes a driving piston. 
   
   
       6 . A device for supplying ink of  claim 1 , wherein the cylinder driving mechanism comprises at least two serial arranged cylinder chambers, which are disposed one above another, each of which includes a driving piston.
