Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es sind Hohlschaft ventile bekannt, die auf auswechselbarem Bolzen, der zugleich zur Führung und zum Zentrieren der Ventilfeder dient, geführt werden.There are hollow shaft valves known that on exchangeable bolt, which serves to guide and center the valve spring at the same time, be guided.

Bekannt ist ferner die Führung der Ventilfeder zwischen zwei Hülsen und die Durchbohrung des Führungsbolzens, sowie die Teilung der Federhülse.Also known is the guidance of the valve spring between two sleeves and the through hole of the guide pin, as well as the division of the spring sleeve.

Gegenstand der vorliegenden Erfindung istThe subject of the present invention is

ίο die gleichzeitige Befestigung und Zentrierung einer zweiteiligen Federhülse in einem einteiligen Gehäuse durch einen sich hierbei selbst zentrierenden Bolzen, sowie die Regelung der Luftpufferwirkung durch einen in der Bohrung des Führungsbolzens verstellbaren Einsatzstift von je nach Bedarf anzupassender Länge.ίο the simultaneous fastening and centering a two-part spring sleeve in a one-piece housing by a here self-centering bolts, as well as the regulation of the air buffer effect by an in the bore of the guide pin adjustable insert pin to be adapted as required Length.

Auf der Zeichnung ist der Erfindungsgegenstand in zwei Ausführungen im Längsschnitt dargestellt.The subject of the invention is shown in two versions in longitudinal section in the drawing shown.

Das mit Durchtrittsöffnungen versehene Gehäuse d besitzt oben eine kreisförmige Austrittsöffnung, die als Sitz für das Ventil c ausgebildet ist. Das Ventil c wird mittels eines Schaftes auf dem Bolzen α geführt, der in der Mitte mit einem Bund und am unteren Ende mit Gewinde zum Aufschrauben von Befestigungsmuttern versehen ist. Der Bund drückt beim Anziehen der Befestigungsmuttein auf die zweiteilige Federhülse b, die oben einen Ansatz trägt, welcher der Feder e als Widerlager dient, während das andere Ende der Feder sich gegen einen Ansatz am Schaft des Ventils c abstützt. The housing d , which is provided with passage openings, has a circular outlet opening at the top, which is designed as a seat for the valve c . The valve c is guided by means of a shaft on the bolt α , which is provided in the middle with a collar and at the lower end with a thread for screwing on fastening nuts. When the fastening nut is tightened, the collar presses on the two-part spring sleeve b, which bears an attachment at the top which serves as an abutment for the spring e , while the other end of the spring is supported against an attachment on the shaft of the valve c .

Die Feder β ist so angeordnet, daß sie zwisehen der Innenwand der Federhülse und der Außenwand des Schaftes am Ventil c geführt wird.The spring β is arranged so that it is guided between the inner wall of the spring sleeve and the outer wall of the shaft on the valve c.

In Fällen, in denen eine Hubbegrenzung notwendig ist, wählt man die Ausführung nach der Fig. 1. Wenn zu befürchten ist, daß sich die Feder β auf den Vorsprung f an der Federhülse b aufsetzt, so kann man den Ansatz am Ventilschaft so ausbilden, wie er auf der linken Seite der Fig. 1 ausgeführt ist.In cases in which a stroke limitation is necessary, the embodiment according to FIG. 1 is selected. If there is a risk that the spring β will sit on the projection f on the spring sleeve b , the approach on the valve stem can be designed in such a way that as it is carried out on the left side of FIG.

Gemäß der Erfindung dient zur Regelung der Pufferwirkung der Stift g, welcher in dem längsdurchbohrten Bolzen a so verstellt werden kann, daß der Inhalt des Pufferraumes h verändert wird.According to the invention, the pin g serves to regulate the buffer effect, which pin can be adjusted in the longitudinally pierced bolt a in such a way that the content of the buffer space h is changed.
