Description
Rohrfederkörper Zusatz zur Patentanmeldung St 9996 IX / 42 d (Auslegeschrift 1039 243) Die Hauptpatentanmeldung betrifft einen Rohrfederkörper für elastische Meßwert- bzw. Hubgeber, bestehend aus falten- bzw. wellenförmig ausgebildeten und sich unter der Einwirkung der zu bestimmenden Meßgröße elastisch verformenden Teilen sowie aus nicht oder nur wenig verformten Teilen, bei welchem die falten- bzw. wellenförmigen Teile als in verschiedenen parallel zueinander liegenden Radialebenen angeordnete Ringsegmente ausgebildet und an der Rohrwandung zueinander derart versetzt sind, daß die nicht oder wenig verformten Wandungsteile ein symmetrisches Netzwerk bilden. Bei derart ausgebildeten Rohrfederkörpern wird eine beachtliche Achsenstabilität erreicht.Bourdon tube addendum to patent application St 9996 IX / 42 d (Auslegeschrift 1039 243) The main patent application relates to a Bourdon tube body for elastic transducers or stroke transducers, consisting of fold- or wave-shaped parts that deform elastically under the influence of the measured variable to be determined, as well as not or only slightly deformed parts, in which the fold or wave-shaped parts are designed as ring segments arranged in different parallel radial planes and offset from one another on the pipe wall in such a way that the non-deformed or slightly deformed wall parts form a symmetrical network. In the case of tubular spring bodies designed in this way, considerable axial stability is achieved.
Die Erfindung betrifft eine Verbesserung eines derartigen Federrohrkörpers, die darin besteht, daß die falten- bzw. wellenförmig verformten Wandteile geschlitzt oder durch Schlitze ersetzt sind. Dadurch wird erreicht, daß die die Schlitze voneinander trennenden Wandteile ein Netzwerk ergeben, dessen Stege Federelemente darstellen, die nach Art beiderseitig eingespannter Blattfedern vorwiegend auf Biegung beansprucht werden können, so daß ein solcher Rohrfederkörper elastischer reagiert als ein solcher nach dem Hauptpatent. Wenn es sich darum handelt, einen geschlossenen Federkörper verwenden zu müssen, beispielsweise bei gasförmigem oder hydraulischem Impuls, können die Schlitze durch Ein- oder Auflegen geeigneter, die Bewegungsmöglichkeit des Rohrkörpers zulassendeWeichstoffe druckdicht verschlossen werden.The invention relates to an improvement of such a spring tube body, which consists in that the fold or wave-shaped deformed wall parts are slotted or replaced by slots. This ensures that the slots are separated from each other separating wall parts result in a network, the webs of which represent spring elements, which, like leaf springs clamped on both sides, mainly stresses bending can be, so that such a Bourdon tube reacts more elastically than such according to the main patent. If it is a question of a closed spring body to have to use, for example with gaseous or hydraulic impulse, can the slots by inserting or laying on suitable, the possibility of movement of the tubular body Allowable soft materials are sealed pressure-tight.
Die Erfindung ist an Hand der Zeichnung an einem Ausführungsbeispiel erläutert. In der Zeichnung stellt dar Abb. 1 den Rohrfederkörper in unbelastetem und Abb. 2 in belastetem Zustand.The invention is based on the drawing of an exemplary embodiment explained. In the drawing, Fig. 1 shows the Bourdon tube body in an unloaded state and Fig. 2 in a loaded state.
An Stelle der gemäß der Hauptpatentanmeldung vorgesehenen wellenförmigen Verformungen sind nach der Erfindung Schlitze 2 vorgesehen; die nicht verformten Wandteile sind mit 2 a bezeichnet. Abb. 2 läßt erkennen, wie sich die durch das Einschneiden der Schlitze verbleibenden waagerechten Stege 2 b nach Art beiderseitig im Bereich der nicht oder wenig verformten Wandteile 2 a eingespannter Blattfedern rechteckigen Querschnitt durchbiegen, bis die sich zugekehrten Kanten der Wandteile 2a aneinanderstoßen.Instead of the undulating one provided according to the main patent application Deformations are provided according to the invention slots 2; the not deformed Wall parts are denoted by 2 a. Fig. 2 shows how the Incision of the slots remaining horizontal webs 2 b of the type on both sides in the area of the non-deformed or slightly deformed wall parts 2 a clamped leaf springs Bend rectangular cross-section until the facing edges of the wall parts 2a butt against each other.
