An injector system (10) adaptable for outputting a predetermined volume of lubricating oil from a diesel engine into an engine fuel system (38) includes a piston (20) slidably disposed in a body (12) and cooperates with the body (12) to define a first and second chamber (22, 23) in the body at opposite ends of the piston (20). A controller (40) controls the movement of a valve (24) to alternately connect the first and second chambers (22, 23) to a pressurized source of oil so that fluid filling one chamber (22) moves the piston (20) which will expel fluid from the other chamber (23). The chamber remains filled until the valve (24) is actuated to connect the unfilled chamber to the pressure source which causes the chamber to fill with oil and expel the oil from the previously filled chamber.

Système d'injecteur (10) conçu pour envoyer un volume prédéterminé d'huile de lubrification d'un moteur Diesel dans un système d'alimentation en carburant moteur (38). Ledit système comprend un piston (20) monté coulissant dans un corps (12) avec lequel (12) il coopère de sorte que des première et seconde chambres (22, 23) soient définies dans ledit corps, aux extrémités opposées du piston (20). Un organe de commande le mouvement d'une soupape (24) pour relier en alternance les première et seconde chambres (22, 23) à une source sous pression d'huile de sorte que le fluide remplissant une chambre (22) déplace le piston (20) qui expulsera le fluide de l'autre chambre (23). La chambre reste remplie jusqu'à ce que la soupape (24) soit actionnée de sorte que la chambre non remplie soit reliée à la source sous pression, la chambre se remplissant ainsi d'huile et l'huile étant expulsée de la chambre précédemment remplie.
