Abstract

Titre : Piston pour pompe de fluide cryogénique L’invention concerne un piston (600) d’une pompe, comprenant :- au moins deux disques (603) superposés l’un sur l’autre, chaque disque (603) présentant une face supérieure (604) et une face inférieure (605) opposée à la face supérieure (604) ;- un joint annulaire continu (606), logé entre les deux disques (603),caractérisé en ce que chaque disque (603) présente, en son centre, un trou débouchant sur la face inférieure (605) et en ce que l’un au moins des disques (603) présente, en son centre, une saillie s’étendant depuis la face supérieure (604) et venant coopérer avec le trou de l’autre des disques (603) de sorte que le joint annulaire continu (606) soit serré entre les disques (603). Figure pour l’abrégé : Fig. 4Title: Piston for cryogenic fluid pump The invention relates to a piston (600) of a pump, comprising:- at least two discs (603) superimposed on each other, each disc (603) having an upper face (604) and a lower face (605) opposite the upper face (604);- a continuous annular seal (606), housed between the two discs (603), characterized in that each disc (603) has, in its center, a hole emerging on the lower face (605) and in that at least one of the discs (603) has, in its center, a projection extending from the upper face (604) and cooperating with the hole on the other of the discs (603) so that the continuous ring seal (606) is clamped between the discs (603).
