Description
Die Membranen von Temperaturreglern, Druckreglern und Fernzündern stellt man häufig aus dünnem Metallblech her, welchem man zum Zwecke leichterer Beweglichkeit eine Wellung gibt. Für die Wellen wählt man meistens die Form konzentrischer Ringe.The membranes of temperature regulators, pressure regulators and remote ignitors are set often made of thin sheet metal, which is used for the purpose of easier mobility there is a curl. The form of concentric rings is usually chosen for the waves.
Nach der Erfindung hat die Wellung der Membran von Temperatur- oder Druckreglern die Form einer sich vom Membranrand nach ihrem Mittelpunkt windenden Schneckenlinie.According to the invention, the corrugation of the membrane has temperature or pressure regulators the shape of a helical line winding from the edge of the membrane towards its center.
Es sind schneckenförmig gewellte Membranen zur Verwendung bei akustischen Apparaten (Mikrophon, Telephon) an sich bereits bekannt, und zwar zudem Zweck, die Eigenschwingung der Membran zu unterdrücken, damit sie möglichst gleichmäßig auf jede Schwingungsfrequenz innerhalb eines bestimmten Frequenzbereiches anspricht. Man fordert von einer Membran für Temperaturregler einen möglichst großen Hub des Mittelteiles, ohne daß die Elastizitätsgrenze überschritten wird. Es hat sich gezeigt, daß diesen Forderungen durch eine schneckenförmige Wellung, unter sonst gleichen Verhältnissen, besonders gut entsprochen wird. Auch die Neigung des ungewellten Mittelteiles beim Zurückgehen aus der gespannten Lage, sich in störender Weise schief zu legen und dann unter knackendem Geräusch auf die andere Seite überzuspringen, ist bei schnekkenförmiger Wellung in weit geringerem Maße vorhanden als bei Membranen mit konzentrisch angeordneten kreisförmigen Wellen.They are helical corrugated membranes for use in acoustic Apparatus (microphone, telephone) already known per se, and in addition the purpose To suppress natural oscillation of the diaphragm so that it is as uniform as possible each oscillation frequency responds within a certain frequency range. Man demands the largest possible stroke of the middle part from a membrane for temperature controllers, without exceeding the elastic limit. It has been shown that these demands by a helical Corrugation, all other things being equal, is met particularly well. Also the inclination of the non-corrugated middle part when going back from the tense position to lie crooked in a disturbing way and then jumping over to the other side with a cracking noise is more like a snail Corrugation is present to a far lesser extent than in the case of membranes with concentrically arranged circular ones Waves.
In Abb. ι ist der Membranquerschnitt durch einen Durchmesser, in Abb. 2 die Aufsicht auf eine solche Membran mit schneckenförmiger Wellung dargestellt.In Fig. Ι the membrane cross-section is through a diameter, in Fig. 2 the plan view of such a membrane with a helical Corrugation shown.
