Abstract
A displacement piston pump has a drive shaft that is driven by a rotating motor. The pump includes a piston which is axially movable within a cylinder and is connected to a piston guide shaft. The drive shaft and the piston guide shaft are rotatably coupled to each other, but some axial movement is permitted between these two members. The drive shaft and the piston guide shaft are coaxially aligned with respect to each other. The piston guide shaft has a guide element connected thereto. The guide element is guided in a guide way. The piston stroke can be maintained with high precision. The piston guide shaft is rotatably and axially supported in a support housing. The support housing contains the guide way therein and a guide element is rigidly connected to the piston guide shaft.
