Definitions

  • a mechanism for turning a shaft comprising a body defining a chamber, the shaft extending across the chamber and projecting from the body, a pair of oppositely disposed pistons movable within the chamber towards and away from one another, the shaft extending between the pistons, each piston including an axially extending toothed arm forming a rack portion, said toothed arm having a hollow structure and being at least partly shaped to conform with the contour of the interior of the chamber, said rack portions meshing with a pinion on the shaft, so that movement of the pistons, under the influence of fluid pressure, results in turning of the shaft, and each piston having, on its face opposite to its toothed arm, several hollow spaces for receiving respective helical springs, characterised in that each toothed arm comprises a first portion projecting from the respective piston and having a hollow structure reinforced by equidistantly distributed walls and being adapted to the inner contour of the chamber; that said toothed arm comprises a second substantially flat and toothed portion project
  • the shape of said pistons is such as to include several helical springs for applying force in opposition to the action of fluid under pressure that acts on the pistons in the centre of the chamber.

  1. Vorrichtung zum Drehen einer Welle (5), mit einem eine Kammer (1) bildenden Körper, wobei die Welle sich durch die Kammer erstreckt und aus dem Körper hervorsteht, einem Paar gegenüberliegenden Kolben (3), welche in der Kammer (1) aufeinander zu und voneinander weg bewegbar sind, wobei die Welle (5) sich zwischen den Kolben (3) erstreckt, jeder Kolben (3) einen sich axial erstreckenden, mit Zähnen versehenen Arm (3"') hat, welcher einen Zahnstangenteil bildet, der gezahnte Arm (3"') hohl und mindestens teilweise geformt ist, um sich der Form des Inneren der Kammer (1) anzupassen, die Zahnstangenteile in ein Ritzel (4) auf der Welle eingreifen, so dass die Bewegung der Kolben (3) unter dem Einfluss des Fluidumdruckes in einem Drehen der Welle (5) resultiert und jeder Kolben (3) auf seiner dem gezahnten Arm (3"') gegenüberliegenden Seite mehrere Hohlräume (8) zur Aufnahme entsprechender Schraubenfedern hat, dadurch gekennzeichnet, dass jeder gezahnte Arm (3"') einen ersten Teil umfasst, welcher von dem entsprechenden Kolben (3) vorsteht und eine Hohlstruktur hat, welche durch in gleichem Abstand verteilte Wände (7) verstärkt ist und ausgelegt ist, um sich der inneren Form der Kammer (1) anzupassen, dass der gezahnte Arm (3"') einen zweiten im wesentlichen ebenen und gezahnten Teil hat, welcher axial von dem ersten Teil absteht, dass jeder Kolben (3) einen hohlen, vorstehenden Strukturteil (3") hat, welcher der inneren Form der Kammer (1) angepasst und angeordnet ist, um den ersten Teil des gezahnten Armes (3"') des anderen Kolbens zu berühren, wenn die Kolben (3) ihre Stellung erreichen, in welcher sie sich am nächsten liegen, und dass jeder Kolben mit einem Schlitz (9) zur aufnahme des freien Endes des zweiten Teiles des gezahnten Armes (3"') des gegenüberliegenden Kolbens, wenn die Kolben (3) sich eng aufeinander zu bewegen, versehen ist.
