PATENTAMT.PATENT OFFICE.
Der Zweck der in der Zeichnung in einem Ausführungsbeispiel dargestellten Erfindung ist, die bei den Bewegungen der Ventile an Ölmotoren auftretenden starken Geräusche vollständig aufzuheben oder wenigstens zu dämpfen. Dieses wird gemäß der Erfindung dadurch erreicht, daß vor dem Ventil eine schalldämpfende Masse angebracht ist, die verhindert, daß die im Ventil vorhandene Luft ο. dgl.The purpose of the invention shown in the drawing in an exemplary embodiment is the loud noises that occur when the valves on oil motors move to cancel or at least to dampen. This is achieved according to the invention in that in front of the valve a sound-absorbing Ground is attached, which prevents the air present in the valve ο. like
ίο in Schall gebende Schwingungen versetzt wird. Das gezeichnete Ausführungsbeispiel stellt ein Lufteinlaßventil dar.ίο is set in sound-producing vibrations. The illustrated embodiment represents an air inlet valve.
Der eigentliche Ventilkörper besteht aus einer mit Lufteinlaßlöchern b versehenen Scheibe a, auf der eine die Luftlöcher b bedeckende Lederplatte c angeordnet ist. Diese Lederplatte wird mittels Federn d gegen die Scheibe a gedrückt, wobei als Widerlager für die Federn d eine zweite. Scheibe e dient, die mittels eines Bolzens f o. dgl. mit der Scheibe α verbunden ist. Es können natürlich Leitstifte g auf einer der Scheiben angeordnet sein, die in entsprechende Vertiefungen der anderen Scheibe eingreifen und als Führungen für die Lederplatte dienen. Über der Scheibe α ist zweckmäßigerweise eine Ventilhaube h angebracht, die mit Öffnungen i für die Luftzufuhr versehen ist. In dieser Haube sind gemäß der Erfindung zwei Ringe k und / angebracht, die beide an den Haubenwandungen anliegen und als Stützen für zwei siebartige Platten m dienen. Zwischen diesen beiden siebartigen Platten ist eine schalldämpfende Masse n, wie z. B. Hanf, Leinen, Wolle oder eine andere faserige Päkkung, eingelegt.The actual valve body consists of a b is provided with air inlet holes disc a, on which a leather covering the air holes b plate is arranged c. This leather plate is pressed against the disc a by means of springs d , with a second abutment for the springs d. Disc e is used, which is connected to the disc α by means of a bolt f or the like. Guide pins g can of course be arranged on one of the disks, which engage in corresponding recesses in the other disk and serve as guides for the leather plate. A valve hood h , which is provided with openings i for the air supply, is expediently attached over the disk α. In this hood two rings k and / are attached according to the invention, both of which bear against the hood walls and serve as supports for two sieve-like plates m . Between these two sieve-like plates is a sound-absorbing mass n, such as. B. hemp, linen, wool or other fibrous packing, inserted.
Wenn die Luft eingesaugt wird, strömt sie durch die Masse η und kann dann durch die Öffnungen b unter Wegpressen der Lederplatte c in den Zylinder gelangen. Das hierbei sonst entstehende, verhältnismäßig starke Geräusch wird durch die schalldämpfende Masse η fast vollständig unterdrückt. Die Masse η dient dabei gleichzeitig als Filter.When the air is sucked in, it flows through the mass η and can then enter the cylinder through the openings b while pressing away the leather plate c. The relatively strong noise that otherwise occurs is almost completely suppressed by the sound-absorbing mass η. The mass η also serves as a filter.
