Description
Saugpumpe. Gegenstand der vorliegenden Erfindung ist eine Saugpumpe, vornehmlich bestimmt zum mühelosen Absaugen der Luft aus Sterili- sierapparaten oder Konservierungsgefässen je der Art.
Ein Ausführungsbeispiel des Erfindungs gegenstandes veranschaulicht in schematischer Darstellung die beiliegende Zeichnung. Das Pumpengehäuse, gebildet durch den Rohr mantel 1, besitzt einerseits eine Stopfbüchse 2, 2a, während es anderseits durch den Griff 3 geschlossen ist. In dem Gehäuse beweglich, jedoch durch die Stopfbüchse 2,'2a abge dichtet, sitzt die hohle Kolbenstange 5, ver sehen mit dem Kolbenleder 6, welches durch die Scheiben 7 und 8 verstärkt ist.
Das aus dem Gehäuse ragende Ende der Kolbenstange ist in die Saughaube 10 ein geschraubt. Diese ist mit einem Dichtungs- gummiring 11 verbunden.
Die Saugwirkung der Pumpe entsteht, wenn man das Gehäuse 1 über die Kolben stange 5 nach unten schiebt.
Hierbei entsteht zwischen dem Kolben 6 und dem untern Ende des Rohrmantels 1 ein Unterdruck, welcher vermittelst der Öffnung 9 durch die hohle Kolbenstange 5 hindurch sich in das Innere der Saughaube 10 fortsetzt und von dieser durch das Ventil 12 hindurch sich dem Sterilisationsgefäss 13 mitteilt.
Beim Niederdrücken des Gehäuses 7 ent weicht die zwischen dem Kolben 6 und dem Griff 3 zusammengepresste Luft durch die Öffnung 4, durch welche auch wieder die Aussenluft auf der Unterseite des Kolbens eintritt, sobald der Kolben über sie hinaus gelangt, und alsdann das entstandene Vakuum aufhebt, was sich durch einen zischenden Laut kundgibt.
Suction pump. The subject of the present invention is a suction pump, primarily intended for the effortless suction of air from sterilizing apparatus or preservation vessels of each type.
An embodiment of the subject invention illustrates a schematic representation of the accompanying drawing. The pump housing, formed by the pipe jacket 1, has a stuffing box 2, 2a on the one hand, while it is closed by the handle 3 on the other hand. Movable in the housing, but sealed by the stuffing box 2, '2a abge, sits the hollow piston rod 5, see ver with the piston leather 6, which is reinforced by the discs 7 and 8.
The end of the piston rod protruding from the housing is screwed into the suction hood 10. This is connected to a rubber sealing ring 11.
The suction of the pump occurs when the housing 1 is pushed over the piston rod 5 downwards.
This creates a vacuum between the piston 6 and the lower end of the pipe jacket 1, which by means of the opening 9 through the hollow piston rod 5 continues into the interior of the suction hood 10 and communicates from this through the valve 12 to the sterilization vessel 13.
When the housing 7 is pressed down, the air compressed between the piston 6 and the handle 3 escapes through the opening 4, through which the outside air also re-enters the underside of the piston as soon as the piston passes over it, and then releases the resulting vacuum what is announced by a hissing sound.
