KlppheLelantrieb fur die Ventile von gleich-Btroogespülten ZweitaktmotorenClapper drive for the valves of flush-flushed two-stroke engines

Bei gleichstroiBgespülten Zweitaktmotoren alt drei im Zylinderdeckel angeordneten Auslaßventilen ist es bekannt, alle Ventile gemeinsam über einen Kipphebel von der Nockenwelle aus anzutreiben und die Verteilung der Kipphebelkraft auf die drei Ventile durch einen Verteilerbügel bzw« eine Verteilerplatte vorjsunehsen· Dieser gemeinsame Antrieb aller drei Ventile hat die folgenden SachteileιIn the case of two-stroke engines flushed with the same flow, three exhaust valves arranged in the cylinder cover, all valves are known jointly driven by the camshaft via a rocker arm and the distribution of the rocker arm force among the three Valves through a distributor bracket or a distributor plate vorjsunehsen · This common drive has all three valves the following Sachteileι

Große Massenkräfte infolge der durch die dreifache Belastung kräftig dimensionierten und deshalb schweren Kipphebel. Ungünstige Konsentration aller Yentilkräfte auf einen Hocken. Gestörte Kraftverteilung auf die einzelnen Ventile beim Brechen einer Ventilfeder oder Klemmen eines Ventileο. Große Bauhöhe durch den kräftigen Kipphebel und den Verteilerbügel· Schwierige Unterbringung des Brennstoffventiles in der Mitte des Zylinderdeckels·Large inertia forces as a result of the triple load powerfully dimensioned and therefore heavy rocker arm. Unfavorable concentration of all Yentil forces on one squat. Disturbed force distribution on the individual valves when breaking a valve spring or clamping of a valve ο. Large overall height Due to the powerful rocker arm and the distributor bracket Difficult to locate the fuel valve in the middle of the cylinder cover

Die Heuerung beseitigt die bekannten Mängel und betrifft einen Einzelantrieb für drei Auslaßventile im Zylinderdeckel von schnellaufenden, gleichstromgesptilten Zweitaktmotoren. Die Heuerung besteht darin, daß für die beiden äußeren symmetrisch sur Sylindemittellinie liegenden Ventile je ein langer Kipp-The hiring eliminates the known shortcomings and concerns a single drive for three exhaust valves in the cylinder cover of high-speed, direct current-filtered two-stroke engines. The hiring consists in that for the two outer ones symmetrically one long toggle valve each on the center line of the cylinder
