Title
(EN) FUEL PRESSURE REGULATOR WITH FUEL TEMPERATURE RESPONSIVE SHAPE MEMORY CALIBRATION
(FR) REGULATEUR DE PRESSION DE CARBURANT A ETALONNAGE PAR ELEMENT A MEMOIRE DE FORME DEPENDANT DE LA TEMPERATURE DU CARBURANT
Abstract
(EN)
A returnless fuel regulator includes a diaphragm assembly dividing the regulator into a control chamber for calibration purposes and a fuel chamber in communication with fuel under pressure from a supply and a fuel rail which receives fuel under regulation pressure. The regulator includes a spring-biased valve element which is opened to a greater or lesser extent by movement of the diaphragm assembly. In the diaphragm assembly, a post is spring-biased into a predetermined position relative to the diaphragm assembly to engage the valve element. The spring is formed of a shape memory alloy which elongates in response to a predetermined temperature of the fuel within the regulator to open or further open the valve element.
(FR)
L'invention concerne un régulateur de carburant sans canalisation, qui comprend un ensemble membrane séparant le régulateur en une chambre de commande servant à l'étalonnage et en une chambre à combustible en communication avec du carburant sous pression provenant d'une alimentation, et une rampe à carburant qui reçoit le carburant soumis à une pression régulée. Le régulateur comprend également un obturateur sollicité par un ressort, qui peut être plus ou moins ouvert par le mouvement de l'ensemble membrane. Dans ce dernier, une tige est maintenue par un ressort en une position prédéterminée par rapport à l'ensemble membrane de façon à être en contact avec l'obturateur. Le ressort est constitué d'un alliage à mémoire de forme, qui s'allonge en fonction d'une température prédéterminée du carburant situé dans le régulateur, de façon à ouvrir ou à ouvrir davantage l'obturateur.
