Abstract (en)
[origin: US4762475A] A thrust piston pump for the delivery of media has a spring constructed in one piece with the piston rod of a piston unit and located in the pump chamber, which is guided on a sloping surface formed by an internal cone. The piston rod is constructed in such a way that an axially resiliently compressible, sleeve-like piston collar can be fitted from the outer end of the piston rod. The fastening cap can be constructed in one piece with a flange edge, a ring packing and/or a component of the cylinder casing, particularly its cylinder cover. This leads to high pump reliability, in the case of simple construction and easy assembly.
