Abstract (en)
[origin: WO9007642A1] A plunger piston of minimal weight and size operates with minimal noise. To this end, the upper region of the piston rod is separated from the piston head by a horizontal slit on the counterpressure side of a plane passing through the longitudinal axis of the piston pin and that of the piston. In addition, the rod can be longer on the pressure side than on the counterpressure side.
