Description

Die bisher bekannten Rückschlagventile bestehen gewöhnlich aus einem Vcritilteller mit Ventilspindel, die durch häufiges Festklemmen und Kanten der Ventilspindel nicht immer zuverlässig arbeiten. Diesem Übelstand ist durch vorliegende Erfindung abgeholfen, indem das .Rückschlagventil neuartigerweise nicht einen Ventilteller mit Ventilspindel, sondern zwei ineinandergreifende Kugeln aufweist, die sichThe previously known check valves usually consist of a Vcritilteller with Valve spindle that is not always reliable due to frequent jamming and edges of the valve spindle work. This disadvantage is remedied by the present invention in that .Non-return valve, in a novel way, not one valve disc with valve spindle, but two has interlocking balls that are

ίο erfahrungsgemäß in ihren Führungen infolge geringerer Reibung1 leichter bewegen als Spindeln. Diese beiden Kugeln, die den Durchtrittskanal abdecken, stehen je unter dem Einfluß einer Feder und bewegen sich unter dem Einfluß des an ihrer Durchdringungslinie sich geltend machenden Flüssigkeitsdruckes auseinander. Experience has shown that 1 move more easily in their guides than spindles due to the lower friction. These two balls, which cover the passage channel, are each under the influence of a spring and move apart under the influence of the fluid pressure which is established on their line of penetration.

Auf der Zeichnung ist der Erfindungsgegenstand in. einem Aueführungsbeispiel schematisch veranschaulicht.In the drawing, the subject matter of the invention is shown schematically in an exemplary embodiment illustrated.

Wie die Zeichnung zeigt, sind· in zur Flüssigkeitsleitung α senkrecht stehenden Bohrungen b, c je eine Kugel f, g angeordnet, von denen eine, etwag, eine kalottenförmigeAs the drawing shows, a ball f, g is arranged in each of the bores b, c perpendicular to the liquid line α , one of which is, somewhat, a dome-shaped one

Tritt nun in der Leitung α ein genügend hoher Flüssigkeitsdruck auf, so wenden die Kugeln f, g auseinanderbewegt, so daß die Flüssigkeit zwischen ihnen hindurchtreten kann.If a sufficiently high liquid pressure occurs in the line α , the balls f, g move apart so that the liquid can pass between them.

Die Mündungskanten der Leitung α können gegenüber den Kugeloberflächen entsprechend geformt sein, um einen dichten Abschluß an diesen zu erhalten.The mouth edges of the line α can correspond to the spherical surfaces be shaped in order to obtain a tight seal on these.
