A cartridge, including the mechanisms for a hydraulic equipment, functionally comprising an envelope (1), a bottom member (5) of the envelope, a pair of plates (7,10) made of hard material, one (7) of which is operatively fixed, while the other (10) one is operatively mobile, a slide (12) for moving the mobile plate, a support member for the operating means along with the operating means themselves, a retaining lid (16), and the packings needed for sealing among said component parts and toward the outside, wherein the bottom member and the operatively fixed plate (7) constitute a single structural element (8A), made by means of one of the processes for making plates of hard material that make it possible to confer to the plates relatively complex configurations. The envelope preferably has, near one of its ends, an internal shoulder (4) suitable for retaining the plate-bottom unit, and the component parts, in their reduced number, are so shaped as to be housed and to be mutually engaged in the cartridge by virtue of their introduction into the envelope along the axial direction and in only one sense, thus constituting an assembly process whose instrumental execution is easy. Advantageously, the mobile plate and the slide also constitute a single structural element (10A).
L'invention concerne une cartouche, incluant des mécanismes pour équipement hydraulique, qui comporte : une enveloppe (1), un élément inférieur (5) d'enveloppe, deux plaques (7,10) faites d'un matériau dur, une (7) des plaques étant fixe et l'autre (10) mobile, un élément coulissant (12) pour déplacer la plaque mobile, un élément support (14) pour moyens de commande ainsi que les moyens de commande eux-mêmes, un couvercle (16) de retenue, et les garnitures d'étanchéité nécessaires pour assurer l'étanchéité entre ces éléments et par rapport à l'extérieur. L'élément inférieur et la plaque (7) fixe constituent un élément structural (8A) unique, obtenu à l'aide d'un des procédés de fabrication des plaques en matériau dur permettant de conférer aux plaques des configurations relativement complexes. L'enveloppe comporte de préférence, près de l'une de ses extrémités, un épaulement (4) interne permettant de retenir l'unité plaques-élément inférieur ; et les éléments constitutifs, en nombre réduit, sont façonnés de façon à pouvoir être logés et mutuellement en prise dans la cartouche, grâce à leur introduction dans l'enveloppe uniquement dans le sens axial. Ce procédé d'assemblage est facile à mettre en oeuvre mécaniquement. La plaque mobile et l'élément coulissant constituent aussi avantageusement un élément structural (10A) unique.
