Description
<Desc/Clms Page number 1>
Elektrohydraulische Verstellvorrichtung
EMI1.1
<Desc/Clms Page number 2>
dgl.derbaren Querschnitten bestehen, deren senkrecht aufeinanderstehende Mittelachsen einLängenverhältnis von maximal 1 : 10 aufweisen. Die Öffnung 63 für das Hubventil 61 ist im Körper 70, der im Ansaugrohr 53 angebracht ist, und die Öffnung 64 für das Senkventil 62 in der ringförmigen Platte 65 angeordnet. Die Wirkungsweise derartiger Ventile ist bekannt und braucht deshalb nicht näher beschrieben zu werden.
Die Ventilöffnungen der Hub-und Senkventile 61 und 62 sind mit Hilfe von das Gehäuse 42 quer durchdringenden Gewindestiften 66 und 67 in ihrem Querschnitt veränderbar, die nach dem Lösen des Deckels 68, der sich neben dem Klemmenkasten 69 befindet, jederzeit zugänglich sind.
In dem zugleich als zentrales Führungsrohr für den Stellkolben 41 dienenden Ansaugrohr 53 ist ein Körper 70 angeordnet, der dieses Ansaugrohr in mehrere in Längsrichtung verlaufende Kammern unterteilt, durch die eine Rotation des hydraulischen Mittels im Ansaugrohr vermieden wird. Die Öffnung 63 für das Hubventil 61 ist in dem Körper 70 angeordnet, so dass dieser einen Teil des Hubventils bildet.
Statt mit der in der Zeichnung dargestellten einstufigen Pumpe kann das Velstellgerät auch mit einer mehrstufigen Pumpe ausgerüstet sein, wodurch eine erhöhte Stellkraft erreicht wird.

Electro-hydraulic adjustment device
EMI1.1
<Desc / Clms Page number 2>
The like of the possible cross-sections exist whose mutually perpendicular central axes have a length ratio of a maximum of 1:10. The opening 63 for the lift valve 61 is arranged in the body 70, which is mounted in the suction pipe 53, and the opening 64 for the lowering valve 62 is arranged in the annular plate 65. The functioning of such valves is known and therefore does not need to be described in more detail.
The cross-section of the valve openings of the lifting and lowering valves 61 and 62 can be changed with the aid of threaded pins 66 and 67 which penetrate transversely through the housing 42 and which are accessible at any time after the cover 68, which is located next to the terminal box 69, has been loosened.
In the suction pipe 53, which also serves as a central guide tube for the actuating piston 41, a body 70 is arranged which divides this suction pipe into several longitudinal chambers, which prevent rotation of the hydraulic means in the suction pipe. The opening 63 for the lift valve 61 is arranged in the body 70 so that it forms part of the lift valve.
Instead of the single-stage pump shown in the drawing, the adjusting device can also be equipped with a multi-stage pump, whereby an increased actuating force is achieved.
