Abstract: front page image
(EN)A valve includes a housing (58) with an elongated bore having a longitudinal axis and a spool (80) reciprocatingly mounted within the bore for relative movement along the bore parallelto the axis. The housing (58) has a housing passageway (62) and the spool has a spool passageway (82). The passageways align in at least one axial position of the spool (80) along the bore, whereby fluids can pass between the spool (80) and the housing (58). The passageway (82) of one of the spoolor the housing includes a first groove which extends parallel to the axis, but not substantially about said one of the spool or the housing. The passageway of another of the spool or the housing includes a second groove which extends circumfernetially about said another of the spool or the housing.
(FR)Cette invention se rapporte à une soupape qui comprend un logement (58) ayant un alésage allongé avec axe longitudinal et un tiroir (80) monté en mouvement alternatif dans l'alésage pour un mouvement relatif le long de l'alésage parallèlement à l'axe. Le logement (58) possède un passage de logement (62) et le tiroir possède un passage de tiroir (82). Ces passages sont alignés au moins dans une position axiale du tiroir (80), le long de l'alésage pour que les fluides puissent passer entre le tiroir (80) et le logement (58). Le passage (82) soit du tiroir soit du logement comporte une première rainure qui s'étend parallèlement à l'axe, mais pas essentiellement autour de l'autre élément, celui sans première rainure. Le passage de l'autre élément sans première rainure comprend une seconde rainure qui s'étend dans le sens circonférentiel autour de cet autre élément.
