Das Zylindergehäuse kann ebenfalls weitere Zu- und Ableitungen aufweisen, um Fluid flexibel führen zu können. Beispielsweise weist das Zylindergehäuse eine weitere Ableitung auf, durch die das Fluid bei geöffnetem Schließkörper und einer Kolbenaufwärtsbewegung an eine weitere Stelle im Fluidkreislauf geführt wird, beispielsweise in einen Fluidtank. Die Steckerbuchse kann wie in den gezeigten Ausführungsbeispielen quer zur axialen Richtung des Zylinders angeordnet sein, die Steckerbuchse kann aber auch in einer beliebigen anderen Ausrichtung angeordnet werden. Das Aktuatorgehäuse kann in das Zylindergehäuse eingepresst werden. Dabei können der Magnetanker und der Schließkörper eine Pressverbindung ausbilden. Es ist keine weitere metallische Materialschicht zwischen dem Aktuatorgehäuse und dem Zylindergehäuse. Der Aktuator ist unter Verzicht auf ein weiteres Gehäuse direkt mit dem Aktuatorgehäuse, das elektrisch isolierend ausgebildet ist, in dem Zylindergehäuse einer Pumpe zur Förderung eines Fluids angeordnet. Bei der Pumpe handelt es sich beispielsweise um eine Kraftstoffhochdruckpumpe einer Einspritzanlage einer Brennkraftmaschine.The cylinder housing may also have other inlets and outlets to flexible fluid to lead to be able to. For example, the cylinder housing has another derivative on, through which the fluid is open Closing body and a piston upward movement is guided to another location in the fluid circuit, for example in a fluid tank. The socket can, as in the embodiments shown be arranged transversely to the axial direction of the cylinder, the socket but can also be arranged in any other orientation become. The actuator housing can in the cylinder housing be pressed. It can the armature and the closing body a press connection form. There is no further metallic material layer between the actuator housing and the cylinder housing. The actuator is directly waiving another housing with the actuator housing, is formed electrically insulating, in the cylinder housing a Pump for promotion a fluid arranged. For example, the pump is to a high-pressure fuel pump of an injection system of an internal combustion engine.
Das Zylindergehäuse ist in einer Ausführungsform einstückig ausgebildet. Der Aktuator ist beispielsweise nicht über Schraubelemente mit dem Zylindergehäuse gekoppelt oder durch Elemente des Zylindergehäuses, die mit dem Zylindergehäuse über Schraubelemente gekoppelt sind, in dem Zylindergehäuse fixiert. Das Zylindergehäuse weist keine Gewinde zur Kopplung mit dem Aktuator beziehungsweise dem Aktuatorgehäuse auf und weist auch keine Gewinde zur Fixierung des Aktuators mit Kopplungselementen auf. Die Pumpe ist in einem Ausführungsbeispiel auch ohne Aktuator und Schließkörper betreibbar, indem das Zylindergehäuse von einem Dichtkörper verschlossen wird.The cylinder housing is in one embodiment one piece educated. For example, the actuator does not have screw elements with the cylinder housing coupled or by elements of the cylinder housing, with the cylinder housing via screw elements are coupled, fixed in the cylinder housing. The cylinder housing points no threads for coupling with the actuator or the actuator housing on and also has no thread for fixing the actuator Coupling elements on. The pump is in one embodiment also operable without actuator and closing body, by the cylinder housing from a sealing body is closed.
Über die Position des Schließkörpers kann der Fluidstrom beziehungsweise der Volumenstrom des Fluids gesteuert werden und somit der Druck, der von der Pumpe bereitgestellt wird, relativ präzise gesteuert werden. In einer Schließposition verhindert der Schließköper einen Fluidfluss von Fluidzuleitung zu Fluidableitung möglichst gut. Durch ein Ansteuern des Aktuators wirkt eine Kraft auf den Schließkörper, so dass dieser seine Position ändert, so dass der Fluidfluss zwischen Fluidzuleitung und Fluidableitung freigegeben ist.About the Position of the closing body can the Fluid flow or the flow rate of the fluid controlled and thus the pressure provided by the pump, relatively precise to be controlled. In a closed position, the closing body prevents one Fluid flow from fluid supply to fluid discharge possible Good. By driving the actuator, a force acts on the Closing body, so that this changes his position, so that the fluid flow between the fluid supply line and fluid discharge is released is.
