Title
(EN) A HIGH PRESSURE SOLENOID VALVE
(FR) ÉLECTROVANNE HAUTE PRESSION
Abstract
(EN) A high-pressure solenoid valve comprising: a valve body comprising an inlet port, an outlet port and a valve head moveable between a first position and a second position to close or open a connection between the inlet port and the outlet port; and a solenoid assembly fixed to the valve body, the solenoid assembly comprising: a magnetic core fixed to the valve head, the core actuatable to move the valve head between the first and second positions; a core tube surrounding the core; and a solenoid coil surrounding the core tube, wherein the core tube comprises an inner sealing sleeve and an outer reinforcing sleeve, the inner sealing sleeve having a radially outer surface and the outer reinforcing sleeve having a radially inner surface, wherein the radially outer surface of the inner sealing sleeve is in contact with the radially inner surface of the outer reinforcing sleeve along substantially the entire axial length of the inner sealing sleeve.
(FR) Électrovanne haute pression comprenant : un corps de vanne comprenant un orifice d'entrée, un orifice de sortie et une tête de vanne mobile entre une première position et une seconde position pour fermer ou ouvrir une liaison entre l'orifice d'entrée et l'orifice de sortie ; et un ensemble solénoïde fixé au corps de vanne, l'ensemble solénoïde comprenant : un noyau magnétique fixé à la tête de vanne, le noyau pouvant être actionné pour déplacer la tête de vanne entre les première et seconde positions ; un tube central entourant le noyau ; et une bobine d'électro-aimant entourant le tube central, le tube central comprenant un manchon d'étanchéité interne et un manchon de renforcement externe, le manchon d'étanchéité interne ayant une surface radialement externe et le manchon de renforcement externe ayant une surface radialement interne, la surface radialement externe du manchon d'étanchéité interne étant en contact avec la surface radialement interne du manchon de renforcement externe sur sensiblement toute la longueur axiale du manchon d'étanchéité interne.
