Description

Gesuch um Eintragung der in nachfolgender Beschreibung und beiliegenden Zeichnung näher bezeichneten Luftpumpe für pneumatischesTankinhaltsmeßgerät in die Rolle für Gebrauchsmuster. Beschreibung : Bei pneumatischen Tankinhaltsmeßgeräten ist es von entscheidender Bedeutung, daß das Rückschlagventil absolut dicht schließt.Request for entry of the in the following description and attached Air pump for pneumatic tank contents measuring device in the drawing Role for utility models. Description: For pneumatic tank content measuring devices it is of crucial importance that the check valve closes absolutely tightly.

Nur hierdurch ist eine Permanentanzeige des Meßgerätes zu erreichen.This is the only way to achieve a permanent display of the measuring device.

Es sind zwar eine große Zahl von federbelasteten Saug-und Druckventilen vorbekannt, doch sind diese durch die geringen Federkräfte nicht absolut dicht. Die geringen Federkräfte können nicht erhöht werden, da die Ventile nicht zwangsgesteuert sind, sondern vom Unterdruck beim Saughub und vom Überdruck beim Druckhub betätigt werden.It is true that there are a large number of spring-loaded suction and pressure valves previously known, but these are not absolutely tight due to the low spring forces. The small spring forces cannot be increased because the valves are not positively controlled but are actuated by the negative pressure on the suction stroke and the overpressure on the pressure stroke will.

Bei der den Gegenstand der Anmeldung bildenden Lösung handelt es sich um eine Kolbenluftpumpe, bei welcher der Druckhub durch die in der vorgespannten Feder gespeicherte Energie erfolgt.The solution forming the subject of the application is a piston air pump, in which the pressure stroke is preloaded by the Spring stored energy takes place.

Die noch in der oberen Totpunktlage vorhandene Federkraft dient gleichzeitig als Schließkraft für das Ventil.The spring force still present in the top dead center position serves at the same time as a closing force for the valve.

Während des Druckhubes wird der 0-Ring (7) durch die Reibung an der Zylinderwand (1) gegen das schräg ausgebildete Ende des Kolbens (6) gedrückt und dichtet ab. Beim Erreichen der oberen Totpunktlage schließt die Hutmutter (8) die Bohrung in der Gummischeibe (4). Die Gummischeibe (4) liegt vor einer Metallscheibe (3), die im Zylinderdeckel (2) dicht verlötet ist.During the pressure stroke, the friction on the O-ring (7) against the Cylinder wall (1) pressed against the inclined end of the piston (6) and seals. When the top dead center position is reached, the cap nut (8) closes the Hole in the rubber washer (4). The rubber washer (4) lies in front of a metal washer (3), which is soldered tight in the cylinder cover (2).

Durch die große Kraft der Schraubenfeder (9) wird eine exakte Permanentanzeige erreicht.The high force of the helical spring (9) provides an exact permanent display achieved.

Der Saugvorgang erfolgt durch den Kolben (6). Beim Saughub legt sich der O-Ring (7) an die Oberkante des Pumpenkolbens (6) und über die Bohrung (5) strömt die Luft in den Kompressionsraum ein.The suction process takes place through the piston (6). During the suction stroke it subsides the O-ring (7) flows to the upper edge of the pump piston (6) and over the bore (5) the air into the compression room.

Schutzansprüche : 1.) Luftpumpe für pneumatisches Tankinhaltsmeßgerät dadurch gekennzeichnet, daß eine auf dem Pumpenkolben sitzende Hutmutter in der oberen Totpunktlage an einer Gummischeibe die Ausströmbohrung dicht abschließt. Protection claims: 1.) Air pump for pneumatic tank content measuring device characterized in that a cap nut seated on the pump piston in the top dead center position on a rubber washer seals the outflow hole tightly.

Claims (1)

2.) Luftpumpe für pneumatisches Tankinhaltsmeßgerät nach Anspruch 1 dadurch gekennzeichnet, daß zur Abdichtung die Federkraft der Luftpumpe selbst benützt wird, bei welcher der Saughub durch mechanische Betätigung erfolgt, der Druckhub hingegen von der in der Schraubenfeder gespeicherten Energie.2.) Air pump for pneumatic tank content measuring device according to claim 1 characterized in that the spring force of the air pump itself for sealing is used, in which the suction stroke takes place by mechanical actuation, the The pressure stroke, on the other hand, depends on the energy stored in the helical spring.
