Abstract
Improvements in the construction of fluid pressure servomotors, of the type comprising a movable wall mounted inside a closed casing and consisting of at least two elements axially spaced and rigidly fixed to a bushing that acts as a stay, defining the said elements with the housing and with a central wall joined to this two groups of variable volume chambers each constituted of a low pressure chamber and of a driving chamber, and said bushing being pierced with a first series of steering ducts axial that puts into communication the aforementioned driving chambers, a second series of conduits that put into communication the said low pressure chambers, and a central cavity joined by two passages transverse to the aforementioned series of conduits, receiving this cavity in sliding to a valve diver driven by an external actuating member and arranged in a manner to be ad the first series of conduits in communication with either said second series of conduits or with a source of high pressure fluid, characterized in that at least one of said steps is provided so as to receive in adjustment to a flat locking member. Which form return stop for said valve diver. (Machine-translation by Google Translate, not legally binding)
