Durch die Ausbildung gemäß Anspruch 2 ergibt sich die Möglichkeit, die Werkstoffe der verschiedenen Einzelteile gezielt an den jeweiligen Zweck anzupassen und dadurch neben einer besonders kostengünstigen Herstellbarkeit eine besonders gute Haltbarkeit zu erzielen.By the training according to claim 2, the results Possibility of the materials of the different items to adapt specifically to the respective purpose and thereby in addition to a particularly cost manufacturability a particularly to achieve good durability.
Durch die Ausbildung gemäß Anspruch 3 gelingt wird eine von der Werkstoffpaarung unabhängige, besonders haltbare Verbindung zwischen dem Kolbenhalter und dem Gleitschuh erhalten.By the training according to claim 3 succeeds a independent of the material pairing, particularly durable Received connection between the piston holder and the shoe.
Durch die Ausbildung gemäß Anspruch 4 wird ein zusätzlicher Schutz der Verbindung zwischen dem Kolbenhalter und dem Gleitschuh erhalten. In bezug auf eine schwingende Belastung ist das von großem Vorteil.By The training according to claim 4 will be an additional Protection of the connection between the piston holder and the shoe receive. In terms of a vibrating load that is of great Advantage.
Durch die Ausbildung gemäß Anspruch 5 wird die Verbindung zwischen dem Gleitschuh und dem Hubring besonders robust und unverlierbar gestaltet, was in bezug auf eine Vereinfachung der Lagerhaltung von Ersatzteilen bedeutsam ist.By The training according to claim 5, the compound between the shoe and the cam particularly robust and captive designed, which in terms of simplification of storage of spare parts is significant.
Durch die Ausbildung gemäß Anspruch 6 wird erreicht, dass der Gleitschuh und der Hubring einander spielfrei berühren, wodurch Klappergeräusche auch nach bereits eingetretenem Verschleiß ausgeschlossen sind.By the training according to claim 6 is achieved that the sliding shoe and the lifting ring touch each other without play, which rattling even after already occurred Wear are excluded.
Durch die Ausbildung gemäß Anspruch 7 wird die notwendige Querverschiebbarkeit des Gleitschuhs in bezug auf den Hubring mit besonders geringem Verschleiß gewährleistet.By The training according to claim 7 is the necessary Transverse slidability of the shoe with respect to the cam ring with ensures particularly low wear.
Durch die Ausbildung gemäß Anspruch 8 wird erreicht, dass sich der Hubring besonders einfach und unter Vermeidung eines Ausbaus der Antriebswelle bewirken lässt.By the training according to claim 8 is achieved that the cam ring is particularly simple and avoiding a Removal of the drive shaft causes.
Durch die Ausbildung gemäß Anspruch 9 wird ein spielfreier Lauf des Hubrings auf dem Exzenter auch nach bereits eingetretenem Verschleiß erzielt.By the training according to claim 9 is a backlash Run the cam ring on the eccentric even after already occurred Wear achieved.
Durch die Ausbildung gemäß Anspruch 10 wird der Verschleiß reduziert, der sich vor allem bei Einspritzdrücken von mehr als 2000 bar ergibt.By the embodiment according to claim 10, the wear is reduced, especially at injection pressures of more than 2000 bar results.
