Abstract

Dispositif d'étanchéité, pour une pompe comportant une tige de piston, un joint annulaire d'étanchéité en matériau élastique, un élément annulaire de soutien. Cet élément de soutien 36 est réalisé en un matériau capable de supporter d'une manière appropriée le joint annulaire d'étanchéité 34; l'élément annulaire de soutien 36 et le joint d'étanchéité 34 sont montés sur la tige de piston de telle manière que l'élément de soutien 36 se trouve du côté à basse pression du joint d'étanchéité 34 et présente des dimensions suffisantes pour supporter d'une manière appropriée le joint annulaire d'étanchéité 34, et des moyens 24, 44, 22 pour faire le joint annulaire d'étanchéité 34 et l'élément annulaire de soutien 36 sur la tige de piston 14. Application : pompes, notamment à liquides abrasifs.Sealing device, for a pump comprising a piston rod, an annular sealing gasket of elastic material, an annular support element. This support member 36 is made of a material capable of adequately supporting the annular seal 34; the annular support member 36 and the seal 34 are mounted on the piston rod such that the support member 36 is on the low pressure side of the seal 34 and has sufficient dimensions to suitably supporting the annular seal 34, and means 24, 44, 22 for making the annular seal 34 and the annular support member 36 on the piston rod 14. Application: pumps, especially abrasive liquids.
