Patent

CA 2652914

A positive displacement pump whose structure allows to increase the pressure of the lubricant taken from the oil sump, wherein the free level surface of the lubricant could even be located far away from the rotating members of the machine. This applies specifically to reciprocating, air compressors, which generally have an oil sump arranged very distant from the drive shaft used to transmit the motion needed for the actuation of the pump. The pump is based on a crank mechanism (7, 7', 7"; 13; 13') that sucks the lubricant and delivers it under pressure, in a target-oriented manner, to the components which require lubrication.

L'invention concerne une pompe volumétrique dont la structure permet d'augmenter la pression du lubrifiant provenant du carter d'huile, la surface de niveau libre du lubrifiant pouvant même être située à distance des éléments rotatifs de la machine. Cela s'applique spécifiquement à des compresseurs d'air alternatifs comprenant généralement un carter d'huile situé à grande distance de l'arbre d'entraînement utilisé pour transmettre le mouvement requis pour l'actionnement de la pompe. Ladite pompe est basée sur un mécanisme de manivelle (7, 7', 7"; 13; 13') qui aspire le lubrifiant et le distribue sous pression, de manière orientée vers la cible, aux composants nécessitant une lubrification.
