Description

Zylinder für Fahrradhilfsmotoren, bei welchem die Ventile im geschlossenen Zylinderkopf angeordnet sind. Vorliegende Erfindung betrifft einen Zylinder für Fahrradhilfsmotoren, bei welchem die im Zylinderkopf angeordneten Ventile zwecks Auswechselbarkeit durch den entsprechend vergrößerten Zündkerzenstutzen :in die Zylinder eingebracht oder aus demselben entfernt werden können.Cylinder for auxiliary bicycle motors, in which the valves are closed Cylinder head are arranged. The present invention relates to a cylinder for Bicycle auxiliary motors, in which the valves arranged in the cylinder head for the purpose of Interchangeability through the correspondingly enlarged spark plug socket: into the Cylinder can be introduced or removed from the same.

.Bei den Zylindern der Kleinmotoren üblicher Bauart sind die Ventile meistens in seitlichen Ventilkammern angeordnet und können, ohne daß ein Entfernen des Zylinders erforderlich ist, durch zweckentsprechende Öffnunge11 herausgenommen werden. Sind, die Ventile hingegen bei einem oben gesohlossenen Zylinder in dessen Zylinderkopf angeordnet, so muß bisher der ganze Zylinder abgenomrnen und der Kollyen: herausgenommen werden, wenn ein Ventil ausgewechselt werden soll.In the cylinders of small engines, the valves are of the usual design mostly arranged in side valve chambers and can without removal of the cylinder is required, taken out through appropriate openings11 will. If, however, the valves are in a cylinder closed at the top Arranged cylinder head, so far the whole cylinder has to be removed and the cylinder: removed when a valve is to be replaced.

Dieser Nachteil wird gemäß der Erfindung dadurch ;beseitigt, daß die Zündikerzenöffnung im Zylinderkopf so angebracht ist und einen solchen lichtem Ouerschnitt erhält, @daß das Ventil durch die Zündkerzenöffnung ein- und ausgebracht werden kann. Ein umständliches Auseinandernehmen des Motors beim Auswechseln des Ventils wird daher vermieden.According to the invention, this disadvantage is eliminated in that the The spark plug opening in the cylinder head is so attached and such a clear cross-section receives @ that the valve can be brought in and out through the spark plug opening can. A cumbersome dismantling of the motor when changing the valve is therefore avoided.

Der Erfindungsgegenstand ist auf beiliegener Zeichnung in einem Ausführungsbeispiel im Längsschnitt veranschaulicht.The subject of the invention is shown in the accompanying drawing in an exemplary embodiment illustrated in longitudinal section.

Der zur Aufnahme des Arbeitskolbens b dienende Zylinder a ist mit dem Zyliniderkopf aus einem .Stück hergestellt. In dem Zylinderkopf sitzt das zur Aufnahme des Ventils c dienende Gehäuse und der Zündkerzenstutzen d. Messer ist :bei der dargestellten Ausführungsform seitlich schräg im Zylinderkopf angeordnet und besitzt eine solche lichte Weite, daß,der Teller des Ventils c leicht hindurchgeführt werden kann, sobald die Zündkerze (strichpuniktiert dargestellt) entfernt ist. Zu diesem Zweck wird das Ventil c aus ,der wirksamen Lage in ,die strichpunktierte Stellung in den Zylinder, dessen Kolben b etwa in die untere Totpunktlvge gebracht worden ist, hineingelassen und darauf in der aus vollen .Linien ersichtlizben Stellung durch die Bohrung des Zündkerzenstutzens entfernt. In gleicher Weise erfolgt das Hineinbringen des Ventils in den Zylinder und das Befestigen desselben vom Zylinderinnern. aus im Ventilgehäuse.The cylinder a serving to accommodate the working piston b is with the cylinder head made from one piece. That sits in the cylinder head Receiving the valve c serving housing and the spark plug socket d. Knife is : in the embodiment shown, arranged laterally at an angle in the cylinder head and has such a clear width that the plate of valve c is easily passed through can be removed as soon as the spark plug (shown in dashed lines) is removed. to for this purpose, the valve c is off, the effective position in, the dash-dotted line Position in the cylinder, the piston b of which is brought approximately into the bottom dead center length has been let in and then in the position visible from full lines removed through the spark plug socket hole. This is done in the same way Bringing the valve into the cylinder and fixing it from the inside of the cylinder. out in the valve body.
