Abstract

L'invention concerne un appareil de commande pour dispositifs actionnés par un fluide sous pression. L'appareil comprend un distributeur comportant un tiroir rotatif 43 entouré d'un fourreau relativement asservi 45 et un dispositif doseur raccordé au fourreau 45. Le distributeur a un plan de référence RP perpendiculaire à son axe de rotation, le tiroir comportant deux rainures de dosage 101R, L disposées de part et d'autre et à égale distance du plan RP. Le fourreau comporte des orifices de pression 83 adjacents au plan RP et raccordés à l'orifice d'entrée et le tiroir comporte des passages de pression axiaux 105R, L qui communiquent chacun avec la rainure de dosage 10lR, L correspondante et qui s'étendent sur une distance suffisante pour communiquer sélectivement avec les orifices de pression 83 lorsque les obturateurs sont déplacés relativement dans l'un ou l'autre sens à partir de la position neutre. L'invention est applicable, notamment, à une commande de direction assistée.The invention relates to a control apparatus for devices actuated by a pressurized fluid. The apparatus comprises a distributor comprising a rotary slide 43 surrounded by a relatively slaved sleeve 45 and a metering device connected to the sleeve 45. The distributor has a reference plane RP perpendicular to its axis of rotation, the slide comprising two metering grooves 101R, L arranged on either side and at an equal distance from the RP plane. The sleeve has pressure ports 83 adjacent to the plane RP and connected to the inlet port and the spool has axial pressure passages 105R, L which each communicate with the corresponding metering groove 10lR, L and which extend a distance sufficient to selectively communicate with the pressure ports 83 when the shutters are moved relatively in either direction from the neutral position. The invention is applicable, in particular, to an assisted steering control.
