Abstract | A static sealing spool valve (210) comprising a valve body (220,230) having a first valve body part (220) and a second valve body part (230), a spool (240) and a seal structure (250). The seal structure (250) comprises a first end seal (254), a second end seal (256) and at least two mid seals (252), wherein the first end seal (254), the second end seal (256) and the at least two mid seals (252) have axially extending projections (258,262) so as to seal the first valve body part (220) and the second valve body part (230). A method of manufacturing a static sealing spool valve (210) is also disclosed.
L'invention concerne une soupape à tiroir (210) à étanchéité statique comprenant un corps de soupape (220, 230) ayant une première partie de corps de soupape (220) et une seconde partie de corps de soupape (230), un tiroir (240) et une structure d'étanchéité (250). La structure d'étanchéité (250) comprend un premier joint d'extrémité (254), un second joint d'extrémité (256) et au moins deux joints intermédiaires (252), le premier joint d'extrémité (254), le second joint d'extrémité (256) et lesdits joints intermédiaires (252) présentent des saillies s'étendant axialement (258 262) de façon à sceller la première partie de corps de soupape (220) et la seconde partie de corps de soupape (230).
