The mechanical Training is simplified.
In der Ausbildung von Anspruch 4 wird ein Ansaugventil gezeigt, das den Pumpenraum unmittelbar begrenzt und das dennoch den extrem hohen Pumpedrücken funktionssicher gewachsen ist.In the formation of claim 4, a suction valve is shown, the the pump room immediately limited and yet the extremely high pump pressures has grown functionally reliable.
Durch die Ausbildung gemäß Anspruch 5 wird eine besonders einfache und robuste Ausbildung und Anbringungsmöglichkeit beider Ventile gezeigt.By the training according to claim 5 becomes a special simple and robust training and attachment both valves shown.
Durch die Ausbildung gemäß Anspruch 6 wird eine Ausbildung des Hochdruckventils gezeigt, die sich einfach herstellen lässt und die dennoch den hohen Druckbelastungen funktionssicher zu widerstehen vermag.By The training according to claim 6 is an education shown the high pressure valve, which can be easily produced and yet to withstand the high pressure loads functionally reliable can.
Durch die Ausbildung gemäß Anspruch 7 wird eine Integration beider Ventile ineinander gezeigt, die besonders einfach montierbar ist. Nach eingetretenem Verschleiß lässt sich die Radialkolbenpumpe besonders einfach in ihre Einzelteile zerlegen und auch von ungeübten Kräften und ohne besondere Anleitung funktionssicher zusammenfügen.By The training according to claim 7 becomes an integration Both valves shown in each other, which is particularly easy to install is. After wear occurs can be The radial piston pump very easy to disassemble into their parts and even by untrained forces and without special Assemble instructions functionally reliable.
Durch die Ausbildung gemäß Anspruch 8 wird sichergestellt, dass trotz des Vorhandenseins von einer Querbohrung im Gehäuse die extrem hohen Pumpendrücke nicht zu einer Beschädigung oder einem Aufreißen des Gehäuses führen können.By the training according to claim 8 is ensured that despite the presence of a transverse bore in the housing the extremely high pump pressures do not damage or can cause a rupture of the housing.
Durch die Ausbildung gemäß Anspruch 9 wird eine besonders druckfeste Bauform des Gehäuses gezeigt, die höchsten Pumpendrücken standhält.By The embodiment of claim 9 will be a particular flameproof design of the housing shown the highest Withstand pump pressures.
