Load changes are advantageous, but have the disadvantage that a reduction in the power output 18, the idle position, the sliding contact would give the engine to idle or at the value 18 a signal to operate a frequency-controlled zero with dead spaces more moderate Size not possible of the speed controller GOV , which is used to manufacture
lung einer elektrischen Verbindung von einem Generator G zu einem Widerstand R vorgesehen ist, wobei der Widerstand Λ durch einen Verbrennungsluftsh orn gekühlt werden kann, der durch eine Luftzuführleitung von einem Gebläse 20 zu einem Brenner 21 geführt wird. Eine temperaturempfiniiliche Einrichtung 22 gibt ein Signal ab, das in einem Verstärker AMPL verstärkt wird und die Zufuhr von Brennstoff und Luft zu dem Brenner 21 regelt.Development of an electrical connection from a generator G to a resistor R is provided, the resistor Λ can be cooled by a combustion air horn which is fed through an air supply line from a fan 20 to a burner 21. A temperature-sensitive device 22 emits a signal which is amplified in an amplifier AMPL and which regulates the supply of fuel and air to the burner 21.
Die dargestellte Vorrichtung zur Leistungsregelung arbeitet wie foigt. Durch Verschieben des Gleitkontaktstücks 18 längs des Kommutators 19 lassen sich unterschiedliche Motorausgangsleistungen erreichen. Eine Verschiebung nach oben verursacht eine Erhöhung der Motorausgangsleistung, indem eine oder mehrere der Spulen erregt werden und dadurch die entsprechenden Rückschlagventile in der geschlossenen Stellung gehalten werden. Die Betätigung eines Rückschlagventils bewirkt, daß in dem einen jeden Ventil zugeordneten Totraum ein minimaler Gasdruck herrscht und somit dieser Raum als ein Totraum unwirksam wird.The power control device shown works as follows. By moving the sliding contact piece 18 along the commutator 19, different motor output powers can be achieved. An upward shift causes an increase in motor output by energizing one or more of the coils, thereby holding the corresponding check valves in the closed position. The actuation of a check valve has the effect that a minimum gas pressure prevails in the dead space assigned to each valve and thus this space becomes ineffective as a dead space.
Wird beispielsweise das Ventil 11 betätigt, um als Rückschlagventil zu wirken, so enthalten alle Toträume 10 und 14 bis 17 Gas konstanten Drucks, der dem minimalen Druck entspricht, welcher während jedes Stirling-Takts auftritt. Alle Druckänderungen während jedes Stirling-Takts treten nur in dem Niedrigtemperatur- und dem Hochtemperatur-Arbeitsraum 6 bzw. 7 und in deren direkten Verbindungsleitungen auf, dit den Kühler 8 und den Regenerator 9 enthalten.If, for example, the valve 11 is actuated to act as a check valve, all contain dead spaces 10 and 14 to 17 constant pressure gas, which corresponds to the minimum pressure which during every Stirling stroke occurs. All pressure changes during each Stirling stroke occur only in the low temperature and the high-temperature working space 6 and 7 and in their direct connecting lines, dit the cooler 8 and the regenerator 9 included.
Während des Leerlaufs, dem die gezeigte Stellung des Gleitkontaktstücks 18 entspricht, verbindet der Drehzahlregler GOV den Generator G mit dem Widerstand R, falis die Motordrehzahl eine vorbe stimmte Leerlaufdrehzahl überschreitet, auf die der Regler GOV eingestellt ist. Dies bedeutet, daß auf dieDuring idling, which corresponds to the position shown of the sliding contact piece 18, the speed controller GOV connects the generator G to the resistor R, if the engine speed exceeds a certain idle speed to which the controller GOV is set. This means that on the
ίο Motorwelle sofort eine Last wirkt und daher die Motordrehzahl abfällt. Sobald die Motordrehzahl eine Drehzahl unterschreitet, auf die der Regler GOV eingestellt ist, werden der Generator G und der Widerstand R getrennt, und die Motorwelle wird von der Last befreit. Da jedoch die von dem Generator G erzeugte Leistung in Wärmeenergie umgewandelt wird, die der zu dem Brenner 21 geleiteten Verbrennungsluft zugeführt wird, steigt die Temperatur in den heißen Teilen des Motors. Dieser Vorgang wird von der temperaturempfindlichen Einrichtung 22 bemerkt, die daraufhin ein Signal abgibt, welches eine Verminderung der Brennstoffzufuhrmenge zu dem Brenner 21 bewirkt.ίο A load acts immediately on the motor shaft and therefore the motor speed drops. As soon as the engine speed falls below a speed to which the controller GOV is set, the generator G and the resistor R are disconnected, and the load is removed from the motor shaft. However, since the power generated by the generator G is converted into thermal energy, which is supplied to the combustion air directed to the burner 21, the temperature in the hot parts of the engine rises. This process is noticed by the temperature-sensitive device 22, which thereupon emits a signal which causes a reduction in the amount of fuel supplied to the burner 21.
Eine erfindungsgemäß ausgebildete Vorrichtung zur Leistungsregelung bewirkt also während des Leerlaufs ein schnelles Ansprechen auf von dem Drehzahlgeber abgegebene Signale, und es treten geringe oder gar keine Schwankungen oder Änderungen in der Leerlaufdrehzahl des Motors auf.A device designed according to the invention for power regulation thus effects during idling a quick response to signals emitted by the speed sensor, and low levels occur or no fluctuations or changes in the idle speed of the engine.
