Abstract

Capteur de levée d'aiguille d'injecteur muni d'un accès dans le prolongement axial de l'aiguille dont la position est à déterminer. Il comprend une première tige 11, susceptible de subir axialement les translations de l'aiguille 6, et montée coulissante dans une embase de capteur 12, qui se visse sur l'injecteur 1, ainsi qu'une seconde tige 16, dans le prolongement axial de la premiere, portant l'une des bornes d'un contact électrique dont l'autre borne 19 est portée par un corps de capteur 14, dans lequel la tige 16 est montée coulissante, et qui est lui-même monté coulissant dans l'embase 12. Au repos, des moyens élastiques 26 ferment le contact entre les bornes 18 et 19, de sorte que, la tige 16 étant appliquée contre la tige 11, les levées de l'aiguille sont transmises par les tiges 11 et 16 à l'encontre des moyens élastiques 26, rompent le contact et donnent un signal de levée d'aiguille. L'invention peut être utilisée pour la détermination de l'origine des temps au sein de blocs de diagnostics pour moteurs diesel.Injector needle lift sensor provided with an access in the axial extension of the needle, the position of which is to be determined. It comprises a first rod 11, capable of axially undergoing the translations of the needle 6, and mounted to slide in a sensor base 12, which screws onto the injector 1, as well as a second rod 16, in the axial extension of the first, carrying one of the terminals of an electrical contact, the other terminal 19 of which is carried by a sensor body 14, in which the rod 16 is slidably mounted, and which is itself slidably mounted in the base 12. At rest, elastic means 26 close the contact between the terminals 18 and 19, so that, the rod 16 being applied against the rod 11, the lifts of the needle are transmitted by the rods 11 and 16 to the 'against resilient means 26, break contact and give a needle lift signal. The invention can be used for determining the origin of times within diagnostic blocks for diesel engines.
