Abstract
The invention relates to a piston pump with a piston, which is guided so that the piston can move axially in a liner that has been inserted into a pump housing and is driven into a reciprocating stroke motion by means of a cam that is driven to rotate. The invention uses a liner that is manufactured as an injection-molded plastic part. The plastic liner has advantages with regard to manufacture, damping behavior when there are pressure changes, and noise generation. Furthermore, the invention proposes affixing a filter integral with the liner when the liner is injection molded.
