Description

Kapselwassermesser mit umlaufendem Ringkolben . Bei Kapselwassermessern mit umlaufendem Ringkolben wurden bisher Kolben aus Hartgummi verwendet, welche in einer Kammer aus Messing oder einem ähnlichen. Material liefen. Dem Bestreben, ein möglichst wasserbeständiges Material zu verwenden, folgend, hat man dann die Kammer, in welcher der Kolben lief, ebenfalls aus Hartgummi gemacht. Nun zeigt sich aber, und das ist eine in der Technik allgemein gemachte Beobachtung, daß gleiche Materialien schlecht aufeinander laufen, so daß die Herstellung von Kolben und Kammer aus Hartgummi keine günstigen Resultate ergab.Capsule water meter with revolving piston. With capsule water meters with a rotating annular piston, pistons made of hard rubber have been used up to now, which in a chamber made of brass or a similar one. Material ran. The endeavor To use a material that is as water-resistant as possible, then you have the following Chamber in which the piston ran, also made of hard rubber. Now it shows but, and this is an observation generally made in technology, the same Materials run poorly on one another, so that the manufacture of piston and chamber hard rubber gave no favorable results.

Diesem Übelstande wird nach der vorliegenden Erfindung dadurch abgeholfen, daB man zur Herstellung der Kammer Hartgummi verwendet, welcher einen Zusatz von Graphit erhalten hat. Dieser Baustoff hat vorzügliche Gleiteigenschaften. Dies ist bei Verwendung der an sich bekannten Hartgummikolben besonders wichtig, da die Reibung dadurch bedeutend vermindert wird, so daB die Empfindlichkeit des Messers erhöht wird.This disadvantage is remedied according to the present invention by that hard rubber is used to manufacture the chamber, which has an addition of Graphite received. This building material has excellent sliding properties. This is when using the hard rubber pistons known per se, it is particularly important because the friction is thereby significantly reduced, so that the sensitivity of the knife increases will.

Auf der Zeichnung ist ein Querschnitt einer solchen MeBkammer mit Kolben dargestellt, wobei mit a der Kolben und mit b die MeBkammer bezeichnet ist.A cross section of such a measuring chamber is shown in the drawing Piston shown, with the piston denoted by a and the measuring chamber with b.
