Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung zur Impulsaufladung einer Brennkraftmaschine, nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for pulse charging an internal combustion engine, according to the preamble of claim 1.

Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung zur Impulsaufladung einer Brennkraftmaschine mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass anders als bei den bekannten Vorrichtungen zur Impulsaufladung das als Schnappscheibe ausgebildete Schließglied in seiner Schließ-Endlage mit relativ niedriger Aufprallgeschwindigkeit auf den Grundkörper auftrifft. Damit wird ein niedriger Störpegel durch Schaltgerausche und eine hohe Standzeit der Vorrichtung erreicht. Je nach Ausgestaltung der Schnappscheibe und des Grundkörpers kann die Vorrichtung bistabil oder monostabil ausgeführt werden. Im Falle der bistabilen Ausführung befindet sich die Schnappscheibe nach jedem Umspringen in einer sicheren Endlage. Im Falle der monostabilen Ausführung hat die Schnappscheibe nur eine stabile Endlage und springt nach dem Umschalten in die Ausgangs-Endlage zurück.The inventive device for pulse charging an internal combustion engine having the features of claim 1 has the advantage that, unlike in the known devices for impulse charging designed as a snap-action shutter member strikes in its closing end position with relatively low impact velocity on the body. Thus, a low noise level is achieved by Schaltgerausche and a long service life of the device. Depending on the configuration of the snap disk and the base body, the device can be made bistable or monostable. In the case of bistable design, the snap disc is in a safe end position after each jump. In the case of the monostable design, the snap disc has only a stable end position and jumps back after switching to the output end position.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Vorrichtung zur Impulsaufladung möglich.The measures listed in the further claims advantageous refinements and improvements of claim 1 device for pulse charging are possible.
