Abstract

At the beginning and end of a working stroke in the steam engine cylinder an induction field is generated. On attaining its end position, the steam engine piston changes the induction field and thus also the control current for the change-over control device. Analogously this control device can be regulated by a compressor piston. The system is intended for a steam engine in which its piston is coupled to the piston of a refrigerator compressor, in which case the engine can be operated not only by steam, but also by coolant vapours. The change-over control of the engine piston can be carried out by rotary or linear sliders, or by a control valve system. A coil for generation of an induction field is mounted at both end points of the engine cylinder, and the piston movement changes the induction field and thus the control current for change-over of an incorporated relay.

Induktive Umsteuereinrichtung für Kurbelwellenlose Dampfmaschinen.Inductive reversing device for steam engines without crankshafts.

Bei Dampfmaschinen, die zum direkten Antrieb von Kompressoren benutzt werden, kann auf die Zwischenschaltung einer Kurbelwelle verzichtet werden, indem der Kolben der Dampfmaschine mit dem entsprechend dimensionierten Kolben z.B. des Kältekompressors mittels einer Kolbenstange verbunden wird.
(Dampf= Wasserdampf oder Kältemitteldampf)In the case of steam engines that are used to drive compressors directly, the interposition of a crankshaft can be dispensed with by connecting the piston of the steam engine to the correspondingly dimensioned piston, e.g. of the refrigeration compressor, by means of a piston rod.
(Steam = water vapor or refrigerant vapor)

Die Umsteuerung des Kolbens der Dampfmaschine kann über Dreh- oder Flachbahnschieber bzw. über Ventilsteuerungen geschehen.The piston of the steam engine can be reversed using rotary or flat slide valves or via Valve controls happen.

(Nachfolgend wird als Sammelbegriff auch für die Dreh- oder Plachbahnschiebersteuerung die Bezeichnung Steuereinrichtung verwendet.)(In the following, the name is also used as a collective term for the rotary or flat track slide control Control device used.)

Zur Betätigung dieser Steuereinrichtung muß Jedoch eine mechanische Abtasteinrichtung am Kolben der Dampfmaschine bzw. an der Kolbenstange angebracht werden, welche z.B. über eine Sprungschaltung die Umsteuerung übernimmt.To operate this control device, however, a mechanical scanning device on the piston must be Steam engine or on the piston rod, which e.g. via a snap switch the Change of direction takes over.

Bei kleineren Agregaten ist diese Lösung wirtschaftlich.This solution is economical for smaller units.

Nachteile sind:Disadvantages are:

hoher mechanischer Anteil und damit Verschleißanfälligkeit, aufwendige Reparaturen,high mechanical content and thus susceptibility to wear, costly repairs,

Umschaltpunkt ungenau.Switching point inaccurate.

Die Neuheit ersetzt die Obertragungsteile vom Kolben bzw. von der Kolbenstange zur Steuereinrichtung durch verschleißfreie elektrische Teile, entsprechend folgendem Schema:The novelty replaces the transmission parts from the piston or from the piston rod to the control device wear-free electrical parts according to the following scheme:

An beiden Endpunkten des Dampfmaschinenzylinders wird jeweils eine Spule zur Erzeugung eines Induktionsfeldes (Magnetfeldes) angebracht. Sobald der mit einer Metallplatte versehene Kolben der Dampfmaschine in der Nähe des Induktionsfeldes kommt, ändert sich der Steuerstrom derart, daß das angeschlossene Relais umgeschaltet wird, somit auch die Steuereinrichtung, die Schubrichtung des Dampfmaschinenkolbens wird umgesteuert.At both end points of the steam engine cylinder there is a coil for generating an induction field (Magnetic field) attached. As soon as the metal-plate piston of the steam engine is nearby of the induction field comes, the control current changes in such a way that the connected relay switches is, thus also the control device, the thrust direction of the steam engine piston is reversed.

Da der Kolben der Dampfmaschine mit dem Kolben des Kompressors unveränderlich verbunden ist, könnte diese Umsteuereinrichtung aAch durch den Kompressorkolben betätigt erden. Vorteil, geringere Temperaturbelastung der Isolierung.Since the piston of the steam engine is invariably connected to the piston of the compressor, this could Reversing device aAch by the compressor piston actuated earth. Advantage, lower temperature load the insulation.
