Title (EN) A VALVE GROUP WITH ELEMENTS IN SHAPE-MEMORY ALLOYS
(FR) GROUPE DE VANNES COMPRENANT DES ÉLÉMENTS EN ALLIAGES À MÉMOIRE DE FORME
Abstract:
(EN) A valve group (10) housable in a duct (40) of a pressurized oil circuit of a vehicle. The valve group (1) extends along an axis (X-X) comprising a valve body (11) axially fixed to the conduit (40) and an obturator (15) fitted, axially movable, on the valve body (11). The obturator (15) has an exchanger aperture (153) through which the oil flows to a heat exchanger (3) comprised in the circuit and an auxiliary aperture (152) through which the oil flows to an auxiliary component of the circuit. The valve group (10) comprises obturator positioning and movement means (18) comprising a pair of elastically yieldable elements (180), of a material selected from among the shape-memory alloys, operatively connected between the valve body (11) and obturator (15), and suitable, as a function of the oil temperature and/or the oil pressure, to permit axial movement, to axially move and to maintain the obturator (15) in a predefined axial position.
(FR) L'invention concerne un groupe de vannes (10) qui peut être logé dans un conduit (40) d'un circuit d'huile sous pression d'un véhicule. Le groupe de vannes (1) s'étend le long d'un axe (X-X) comprenant un corps de vanne (11) fixé axialement au conduit (40) et un obturateur (15) monté de façon axialement mobile sur le corps de vanne (11). L'obturateur (15) comporte une ouverture d'échangeur (153) à travers laquelle l'huile s'écoule vers un échangeur de chaleur (3) inclus dans le circuit et une ouverture auxiliaire (152) à travers laquelle l'huile s'écoule vers un composant auxiliaire du circuit. Le groupe de vannes (10) comprend des moyens de positionnement et de déplacement d'obturateur (18) comprenant une paire d'éléments élastiquement déformables (180), en un matériau sélectionné parmi les alliages à mémoire de forme, reliés de manière fonctionnelle entre le corps de vanne (11) et un obturateur (15) et aptes, en fonction de la température de l'huile et/ou de la pression d'huile, à permettre un mouvement axial, de façon à se déplacer axialement et à maintenir l'obturateur (15) dans une position axiale prédéfinie.
