Regelvorrichtungen ohne Hebelübertragung sind bereits bekannt für Ausführungen mit Regelschiebern, welche durch Geschwindigkeitsregler betätigt werden. Bei Leistungsregelvorrichtungen dagegen werden bisher Hebelübertragtmgen benutzt, weil die Regelvorrichtung ohne Hebelübertragung zu schwerfällig wird. Diesen Übelstand vermeidet die vorliegende Erfindung, indem durch Zwischenschaltung einer Vorsteuerung die Regelschieberbüchse ohne Hebelübertragung durch Kraftmittel bewegt wird.Control devices without lever transmission are already known for designs with Control slides, which are operated by speed regulators. With capacity control devices on the other hand, lever transmission mechanisms have hitherto been used because the control device becomes too cumbersome without lever transmission. The avoids this evil present invention, by interposing a pilot control, the control slide sleeve is moved by power means without lever transmission.

Die Zeichnung zeigt ein Beispiel des Gegenstandes vorliegender Erfindung.The drawing shows an example of the subject matter of the present invention.

Ein Geschwindigkeitsregler verstellt einen Regelschieber α und beeinflußt eine ölabflußöffnung b, welche Drucköl zu Regelventilen der Kraftmaschine zu- und abströmen läßt. Außer von dem Regelschieber wird die Ölab-A speed controller adjusts a control slide α and influences an oil discharge opening b, which allows pressure oil to flow in and out to the control valves of the engine. In addition to the control slide, the oil drain is

ao flußöffnung von einer Regelschieberbüchse c beeinflußt. Die Bewegung dieser Regelschieberbüchse erfolgt von einem die Leistung der Maschine beeinflussenden Regler. Bei unmittelbarer Verschiebung der Regelschieberbüchse c ist nun immerhin für den Regelungsvorgang eine verhältnismäßig große Kraft erforderlich, welche den Regelungsvorgang ungünstig beeinflußt. Die Bewegung der Regelschieberbüchse erfolgt gemäß vorliegenderao flow opening influenced by a control slide sleeve c . The movement of this regulating slide bushing is carried out by a regulator that influences the performance of the machine. When the control slide sleeve c is moved directly, a relatively large force is required for the control process, which has an unfavorable effect on the control process. The movement of the control slide bushing takes place in accordance with the present

Erfindung nun dadurch, daß die RegelschieInvention now by the fact that the Regelschie

berbüchse durch eine Vorsteuerung mittels Drucköls verschoben wird. Die Vorsteuerung besteht aus einem Vorsteuerschieber d, welcher den Druckölzufluß e in der Ruhelage der Regelschieberbüchse c absperrt. Beim 35 Verschieben des Vorsteuerschiebers d folgt die Regelschieberbüchse stets den Bewegungen des Vorsteuers'ohiebers. Die Verschiebung der Regelschieberbüchse ist somit von der Verschiebung einer kleinen, leicht gangbaren 40 Spindel abhängig gemacht, so daß eine leicht gehende und empfindliche Regelung erzielt wird.is shifted by a pilot control by means of pressure oil. The pilot control consists of a pilot valve d, which shuts off the pressure oil flow e in the rest position of the control slide sleeve c . When the pilot valve d is moved , the control valve sleeve always follows the movements of the pilot valve. The displacement of the control slide sleeve is thus made dependent on the displacement of a small, easily maneuverable spindle, so that an easy-going and sensitive control is achieved.
