Description
An dem Rohr α b, durch welches der Schlauch c d geht, ist der Rahmen k I mn befestigt, welcher den Ausschnitt h i enthält. In diesem Ausschnitte und in der Oeffnung/ des Rohres α b bewegt sich der Stempel g ef. Mittelst des Knopfes/ drückt man den Stempel herunter und schiebt ihn, wie Fig. 1 und 3 zeigen, mit seinem stärkeren Ansatz bei e unter den Schlitz bei i ein, wodurch der Schlauch bei q verschlossen wird. In dieser Verschlufslage hält sich der Stempel g ef zufolge der Elasticität des Schlauches selbstthätig so lange, bis man denselben wieder nach h herüber drückt, worauf derselbe durch die Elasticität des Schlauches und den Druck der Flüssigkeit in die in Fig. 2 und 4 gezeichnete Stellung gehoben wird. The frame k I mn , which contains the cutout hi , is attached to the tube α b through which the hose cd passes. The punch g ef moves in this cutout and in the opening / of the tube α b. In the middle of the button / one presses the punch down and, as shown in FIGS. 1 and 3, pushes it with its stronger attachment at e under the slit at i , which closes the tube at q . In this closed position, the plunger g ef holds itself automatically, due to the elasticity of the hose, until it is pushed back over to h , whereupon it is lifted into the position shown in FIGS. 2 and 4 by the elasticity of the hose and the pressure of the liquid will.
In Fig. 5 ist angedeutet, wie man auf zwei verschiedene Arten auf verschieden dicke Schlauchwände Rücksicht nehmen kann, damit bei ganz dickwandigem Schlauche die Pressung nicht übermäfsig stark werde und bei ganz dünnen Schläuchen der Druck zum vollen Abschlufs ausreiche. Dies geschieht entweder durch ein Gewinde bei k1 P, wodurch der Schlitz hi, hinter welchen sich e1 legt, entsprechend höher oder niedriger gestellt wird,' oder dadurch, dafs der Stempel bei g1 oder bei χ mit einem elastischen Theil versehen wird.In Fig. 5 it is indicated how one can take into account hose walls of different thicknesses in two different ways, so that the pressure does not become excessively strong with very thick-walled hoses and the pressure is sufficient for full closure with very thin hoses. This is done either by a thread at k 1 P, whereby the slot hi, behind which e 1 lies, is set correspondingly higher or lower, or by providing the punch at g 1 or at χ with an elastic part.
