Abstract
This invention relates to a hydraulic element comprising a sleeve-shaped housing and a piston reciprocating longitudinally within the sleeve-shaped housing. To provide a hydraulic element for transporting small amounts of liquid in a displacement pump, wherein the risk of hydraulic element rupture or deflection is reduced, the invention proposes that the piston has a chamber extending longitudinally and having a chamber inlet, wherein a pin is provided, passing through the chamber inlet into the chamber, and connected to the sleeve-shaped housing at or by means of an intermediate element, such that relative movement between the piston and the pin is generated during the reciprocating motion of the piston. The invention also relates to a displacement pump having a hydraulic element according to the invention.
