Description
Druckabfall am Drehzahlregler 13 wird über die Leitungen 17, 26 und 26'auf die entgegengesetzten Seiten einer Membran 27 übertragen, die das Steuerglied 28 des servobetätigten Ventils 14 trägt.Pressure drop across the speed controller 13 is over the lines 17, 26 and 26 'are transferred to the opposite sides of a membrane 27 which controls the control member 28 of the servo-operated valve 14 carries.
In die Leitung 26 ist ein Rückschlagventil 50 und dahinter ein Druckregler 29 eingeschalter, der im Ausführungsbeispiel an den Eintritt und Austritt und außerdem noch an einen Zwischendruck des Triebwerkskompressors angeschlossen ist.A check valve 50 and, behind it, a pressure regulator 29, which in the exemplary embodiment to the inlet and outlet and also to an intermediate pressure of the engine compressor connected.
Der an Drosseln 30, 31 anliegende Differenzdruck zwischen Kompressoreintritt und -austritt wird einem Balg 32 des Druckreglers 29 zugeführt, während der Zwischendruck über eine Leitung 49 einer Kammer 51 zugeführt wird, in der ein Balg 46 angeordnet ist, der mit einem Balg 45 in Verbindung steht. Beide Bälge 45, 46 sind evakuiert.The differential pressure between the compressor inlet and outlet at throttles 30, 31 becomes a The bellows 32 of the pressure regulator 29 is supplied, while the intermediate pressure is fed to a chamber via a line 49 51 is supplied, in which a bellows 46 is arranged, which is connected to a bellows 45. Both Bellows 45, 46 are evacuated.
Am Balg 32 ist ein Zapfen 47 und an den äußeren Enden der Bälge 45 und 46 eine die Bälge durchdringende Stange 48 befestigt; zwischen Zapfen und Stange ist ein Hebel 35 schwenkbar angeordnet, der an seinem Ende eine Schneide 36 trägt, die den Zufluß aus der Leitung 26 steuert.On the bellows 32 there is a pin 47 and on the outer ends of the bellows 45 and 46 there is a pin which penetrates the bellows Rod 48 attached; a lever 35 is pivotably arranged between the pin and the rod at its end there is a cutter 36 which controls the inflow from the line 26.
Die Wirkflächen der Bälge 45, 46 unterscheidenThe active surfaces of the bellows 45, 46 differ
sich voneinander im Verhältnis der Drücke, die auf diese ausgeübt werden. Der Balg 46 hat also einen größeren Durchmesser als der Balg 45. Die inneren Enden dieser Bälge sind am Gehäuse abgestützt.from one another in relation to the pressures that are exerted on them. So the bellows 46 has one larger diameter than the bellows 45. The inner ends of these bellows are supported on the housing.
Der Innenraum des Druckreglers 29 ist über eine Leitung 38, die eine einstellbare Drossel 39 und ein Überdruckventil 40 enthält, mit dem Einlaß der Pumpe 11 verbunden. Das Überdruckventil 40 gibtThe interior of the pressure regulator 29 is via a line 38 which has an adjustable throttle 39 and a Pressure relief valve 40 is connected to the inlet of the pump 11. The pressure relief valve 40 gives
ίο nur dann einen Brennstofffluß durch die Leitung 38 frei, wenn der Förderdruck der Pumpe einen vorbestimmten Wert überschreitet.ίο only a flow of fuel through line 38 free when the delivery pressure of the pump exceeds a predetermined value.
Falls erforderlich, wird ein weiterer Drehzahlregler 41 verwendet, mit dem der Druck im Balg 32 mittels eines Abflußventils 42 vermindert werden kann. Die Stellung dieses Abflußventils wird durch die Drehzahl eines Rotors 43 bestimmt, der im Ausführungsbeispiel von einer freien Gasturbine (nicht gezeigt) über eine Welle 44 angetrieben wird. Statt dessen kann es auch die andere von zwei unabhängigen, je einen Kompressor und eine Turbine tragenden Wellen des Gasturbinentriebwerks sein.If necessary, a further speed controller 41 is used, with which the pressure in the bellows 32 by means of a drain valve 42 can be reduced. The position of this drain valve is determined by the The speed of a rotor 43 is determined, which in the exemplary embodiment is driven by a free gas turbine (not shown) is driven via a shaft 44. Instead, it can also be the other of two independent, each be a compressor and a turbine-bearing shafts of the gas turbine engine.
