Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Da sich bei dem Ventil des Haupt-Patentes herausgestellt hat, dafs beim Schliefsen die durch den Kataraktkolben verursachte Luftverdünnung unzureichend ist, um ein zu heftiges Aufschlagen des Ventils beim Schlufs zu verhindern, wurde die dargestellte Einrichtung getroffen, mittelst welcher auch beim Schlufs des Ventils ein Luftkatarakt gebildet und so ein ganz sanftes Schliefsen erzielt wird.Since it has been found with the valve of the main patent that the The air dilution caused by the cataract bulb is insufficient to cause excessive The device shown was to prevent the valve from opening when it closes hit, by means of which an air cataract is formed when the valve closes, and so on a very gentle closing is achieved.

Es bezeichnet C das Druckventilgehäuse, b den Ventilsitz, α den Ventilkegel, mit dessen Stange der Kolben m fest verbunden ist. Der Raum g wird durch das Führungsstück k nach der inneren Seite abgeschlossen, während früher dasselbe nur durch die Kapsel e nach aufsen abgeschlossen war. Aus dem. Ringe g führen zwei feine Bohrungen i und I1 nach dem Raum des Ventilgehäuses. Die Feder f erhöht die Sicherheit des rechtzeitigen Schliefsens.It denotes C the pressure valve housing, b the valve seat, α the valve cone, with the rod of which the piston m is firmly connected. The space g is closed off on the inside by the guide piece k , whereas previously the same was closed off on the outside only by the capsule e. From the. Rings g lead two fine bores i and I 1 to the space of the valve housing. The spring f increases the security of timely closing.

Beim Oeffnen bleibt die Wirkungsweise des Ventils genau die frühere, beim Schliefsen hingegen wird durch den Kolben m die Luft aus dem Räume g durch die Oeffnung Z1 herausgeprefst, und nach dem Ueberschreiten der Oeffnung Z1 ist auch ein wirksamer Luftbuffer für das Aufsitzen des Ventils geschaffen.When opening the valve remains exactly the same as before, when closing, however, the piston m presses the air out of the room g through the opening Z 1 , and after crossing the opening Z 1 there is also an effective air buffer for the valve to sit on created.

Claims (1)

Patent-Anspruch:Patent claim: An dem durch Patent-Anspruch 2. des Patentes No. 27413 gekennzeichneten Ventile die Hinzufügung einer zweiten Oeffnung I1 und eines zweiten geschlossenen Raumes gx, in welchem durch den Kolben m beim Schliefsen des Ventils Luft oder Gas verdichtet wird, um den harten Aufschlag des Ventils wirksamer abzuschwächen, als dies bei blofser Luftverdünnung in dem Räume g möglich ist.On the basis of patent claim 2 of patent no. 27413 marked the addition of a second opening I 1 and a second closed space g x , in which air or gas is compressed by the piston m when the valve is closed, in order to weaken the hard impact of the valve more effectively than with mere air dilution in the Spaces g is possible.
