Abstract

Dispositif d'étanchéité et de lubrification des pistons plongeurs d'une pompe. Une chambre ménagée coaxialement à chaque plongeur dans le bloc de cylindres de la pompe comprend des parties avant et arrière séparées par une gorge annulaire. Un élément de retenue disposé dans ladite chambre contient dans sa partie arrière une garniture d'étanchéité arrière et porte par sa surface avant contre une garniture d'étanchéité avant Une garniture de graissage disposée derrière la. garniture d'étanchéité arrière plonge dans l'huile que contient un bac. Des conduits et des ouvertures de l'élément de retenue recyclent le liquide passant par la garniture avant dans la chambre d'aspiration de la pompe. L'huile de lubrification et le liquide pompé sont séparés par la garniture d'étanchéité arrière. Application aux pompes qui équipent des appareils de pulvérisation.A device for sealing and lubricating the plungers of a pump. A chamber formed coaxially with each plunger in the cylinder block of the pump comprises front and rear parts separated by an annular groove. A retaining element arranged in said chamber contains in its rear part a rear seal and carries by its front surface against a front seal A lubricating seal disposed behind the. rear seal is immersed in the oil contained in a pan. Ducts and openings in the retainer recycle the liquid passing through the front seal to the pump suction chamber. Lubricating oil and pumped liquid are separated by the rear seal. Application to pumps which equip spraying devices.
