Description
In der F i g. 2 ist der Dichtungsspalt 25 zwischen dem
Saugventilkörper 8 und der Hülse 13 des Plungers 2 in
vergrößertem Maßstab aufgezeigt.In FIG. 2 is the sealing gap 25 between the
Suction valve body 8 and the sleeve 13 of the plunger 2 in
shown on an enlarged scale.
Der im Druckraum Pi herrschende Druck fällt in
dem Dichtungsspalt 25 in Richtung auf die Antriebsseite
des Plungers ab und erreicht im Endbereich des
Ringraumes 14 einen Wert FI. The pressure prevailing in the pressure chamber Pi falls in
the sealing gap 25 in the direction of the drive side
of the plunger and reaches the end of the
Annular space 14 has a value FI.
Da der Ringraum 14 gegenüber dem vorderen Ende
des Plungers ein wenig in Richtung auf die AntriebsseiteSince the annular space 14 opposite the front end
the plunger a little towards the drive side
versetzt liegt, ist beim Druckhub der Druck im Dichtungsspalt, der dem Ringraum 14 zugeordnet ist, geringer als der Druck im Ringraum 14, der mit dem Druck in dem Druckraum 17 übereinstimmt Hierdurch ergibt sich eine Verformung der Hülse 13, die in der Fig. 2 gestrichelt angeordnet ist und zu einer Verringerung des Querschnittes des Dichtungsspaltes 25 führt.is offset, during the pressure stroke the pressure in the sealing gap that is assigned to the annular space 14 is lower than the pressure in the annular space 14, which corresponds to the pressure in the pressure space 17 results in a deformation of the sleeve 13, which is arranged in dashed lines in Fig. 2 and to a Reduction of the cross section of the sealing gap 25 leads.
