Abstract

Pompe pistons du type à plateau oscillant à pression constante et débit variable. Des moyens sensibles à une pression déterminée du collecteur agissent sur le plateau oscillant pour faire varier la course des pistons. Une telle pompe est utilisée notamment dans les systèmes d'injection de carburant à commande électronique pour moteurs Diesel.Swash plate type piston pump with constant pressure and variable flow. Means sensitive to a determined pressure of the manifold act on the swash plate to vary the stroke of the pistons. Such a pump is used in particular in electronically controlled fuel injection systems for diesel engines.
