Am Lenker 1 ist mittels einer ihn umfassenden Rohrschelle 3 und einer Schraube 4 ein Bremszylindergehäuse befestigt, an welchem ein Betätigungshebel 6 schwenkbar gelagert ist.Fig. 1 shows the right end of the tubular Handlebar 1 of a two-wheeled vehicle, in particular a bicycle, with pushed-on grip sleeve 2, which is held in the driver's right hand. On the handlebar 1 is by means of a pipe clamp encompassing it 3 and a screw 4, a brake cylinder housing is attached, on which an actuating lever 6 is pivotable is stored.
Wie insbesondere aus Fig. 3 ersichtlich, enthält das Bremszylindergehäuse 5 einen Bremszylinder 7 mit einem in diesem verschieblichen Kolben 8, der seinerseits durch den Betätigungshebel 6 bei einem Bremsvorgang (in Fig. 3 nach links) verschiebbar ist und über die im Bremszylinder 7 enthaltene Bremsflüssigkeit die Bremse betätigt. Der Kolben 8 ist durch eine Feder belastet, die ihn in der in Fig. 3 gezeichneten Endlage hält, in welcher die Bremse geöffnet ist. über eine Stellschraube 11, die gelenkig mit dem Betätigungshebel 6 verbunden ist, kann diese Endlage desAs can be seen in particular from FIG. 3, the brake cylinder housing 5 contains a brake cylinder 7 with a in this displaceable piston 8, which in turn by the actuating lever 6 during a braking process (in Fig. 3 to the left) is displaceable and the brake fluid contained in the brake cylinder 7 Brake applied. The piston 8 is loaded by a spring which moves it into the end position shown in FIG holds in which the brake is open. Via an adjusting screw 11, which is articulated with the operating lever 6 is connected, this end position of the

Kolbens 8 in an sich bekannter Weise so eingestellt werden, daß kein totes Spiel bei Verschwenkung des Betätigungshebels 6 entsteht/ sondern die Bremse sofort greift. Die Bremsflüssigkeit wird über eine Rohrleitung 1o der (nicht dargestellten) Bremse zugeleitet. Piston 8 can be adjusted in a known manner so that no dead game when pivoting the Actuating lever 6 arises / but the brake engages immediately. The brake fluid is supplied via a Pipeline 1o supplied to the brake (not shown).
Zum Ein- oder Nachfüllen von Bremsflüssigkeit ist in einer Wand 12 des Bremszylinders 7 eine Öffnung 13 in Form einer Bohrung vorgesehen, welche durch eine Schraube 14 druckdicht verschließbar ist.For filling or refilling of brake fluid, an opening 13 is provided in a wall 12 of the brake cylinder 7 Provided in the form of a bore which can be closed in a pressure-tight manner by a screw 14.
Um bei gelöster Schraube 14 Bremsflüssigkeit in einfacher Weise und ohne besondere Hilfsmittel einfüllen zu können, ist die Öffnung 13 an der Außenseite des Zylinders 7 von einer in sich geschlossenen, einen zylindrischen Trichter 15 bildenden Wand 16 umgeben. Der Trichter 15 ist durch einen Schraubdeckel 17 verschließbar und steht wie ein Zylinder nach außen vom Bremszylinder 7 ab. Die mit der Drehachse der Schraube 1 4 zusammenfallende Mittelachse des einen kreiszylindrischen Behälter bildenden Trichters 15 liegt in der Ebene, in der sich auch die Verschwenkung des Betätigungshebels 6 vollzieht. Diese Ebene ist in Fig. 1 und 3 die Zeichnungsebene. Diese Ausbildung hat den Vorteil, daß das Bremszylindergehäuse 5 mit dem daran angelenkten Betätigungshebel 6 nicht nur auf der rechten Seite des Lenkers - wie auf der Zeichnung· dargestellt - sondern auch auf der linken Lenkerseite angeordnet werden kann.To with loosened screw 14 brake fluid in easier Way and without special tools to be able to fill, the opening 13 is on the outside of the Cylinder 7 surrounded by a self-contained wall 16 forming a cylindrical funnel 15. The funnel 15 can be closed by a screw cap 17 and is like a cylinder to the outside Brake cylinder 7 from. The central axis of the one circular cylindrical which coincides with the axis of rotation of the screw 1 4 Container-forming funnel 15 lies in the plane in which the pivoting of the Actuating lever 6 takes place. This plane is the plane of the drawing in FIGS. 1 and 3. This training has the advantage that the brake cylinder housing 5 with the actuating lever 6 hinged to it not only on the right side of the handlebar - as shown in the drawing - but also on the left side of the handlebar can be arranged.

Zum Einfüllen von Bremsflüssigkeit wird die Schraube 14 im Ansatz 18 etwas nach oben herausgedreht, so daß- sich über die Schlitze 19 eine Verbindung zwischen dem Innenraum des Trichters 15 und dem Innenraum des Bremszylinders 7 ergibt. Nunmehr kann in die verhältnismäßig weite öffnung des Trichters 15 Bremsflüssigkeit eingefüllt werden, die über die Schlitze 19 und die öffnung 13 in das Innere des Bremszylinders 7 fließt und diesen vollständig füllt. Hierauf wird die Schraube 14 wieder so weit eingedreht, bis sie die öffnung 13 flüssigkeitsdicht verschließt, überschüssige Bremsflüssigkeit im Trichter 15 kann gegebenenfalls in diesem verbleiben, wenn er durch den Deckel 17 ebenfalls flüssigkeitsdicht verschlossen wird. Zum Einfüllen der Bremsflüssigkeit wird das Bremszylindergehäuse, z. B. nach Lösen der Schrauben 4 an der Rohrschelle 3 so gedreht, daß die öffnung des Trichters 15 nach oben weist, wie dies Fig. 4 zeigt.To fill in brake fluid, the screw 14 in the shoulder 18 is unscrewed slightly upwards, see above that a connection between the interior of the funnel 15 and the interior of the Brake cylinder 7 results. Now can in the proportionate wide opening of the funnel 15 brake fluid can be filled in via the slots 19 and the opening 13 flows into the interior of the brake cylinder 7 and completely fills it. Then will the screw 14 is screwed in again until it closes the opening 13 in a liquid-tight manner, excess Brake fluid in the funnel 15 can optionally remain in this when it is through the lid 17 is also closed in a liquid-tight manner. To fill up the brake fluid, the Brake cylinder housing, e.g. B. after loosening the screws 4 on the pipe clamp 3 rotated so that the opening of the funnel 15 points upwards, as shown in FIG.
