Abstract

La présente invention a pour objet un capteur de pression (1) destiné à être monté sur un élément d'interface moteur (3) pour mesurer la pression dans un moteur thermique de véhicule comprenant : - un boîtier de protection (2) dans lequel sont logés un substrat et une sonde de pression connectée au substrat, - une tête de mesure (4) faisant saillie sur le boîtier de protection (2) et destinée à être insérée dans un orifice de l'élément d'interface moteur (3) délimité par une paroi (7) circulaire, la tête de mesure (4) comprenant une portion de fixation circulaire reliée au boîtier de protection (2) et comprenant au moins deux ergots de fixation (5) destinés à s'insérer chacun dans une gorge (8) prévue dans la paroi (7) de l'élément d'interface moteur (3) pour fixer le capteur de pression (1) sur l'élément d'interface moteur (3), la rotation du capteur de pression (1) dans l'orifice de l'élément d'interface moteur (3) suivant un sens de fixation (B) entrainant le coulissement des ergots de fixation (5) dans leurs gorges (8) respectives et la translation du capteur de pression (1) vers l'élément d'interface moteur (3) jusqu'à une position de fixation. La tête de mesure (4) comprend un moyen d'étanchéité radial. Selon l'invention, le capteur de pression (1) comprend un moyen de maintien (10) du capteur de pression (1) en position de fixation permettant de bloquer le mouvement de rotation de ce dernier suivant un sens de rotation contraire au sens de fixation (B) lorsqu'il est fixé sur l'élément d'interface moteur (3).The present invention relates to a pressure sensor (1) intended to be mounted on an engine interface element (3) to measure the pressure in a vehicle thermal engine comprising: - a protective housing (2) in which are housed a substrate and a pressure probe connected to the substrate, - a measuring head (4) projecting from the protective housing (2) and intended to be inserted into an orifice of the motor interface element (3) delimited by a circular wall (7), the measuring head (4) comprising a circular fixing portion connected to the protective housing (2) and comprising at least two fixing lugs (5) intended to each insert into a groove ( 8) provided in the wall (7) of the motor interface element (3) to fix the pressure sensor (1) on the motor interface element (3), the rotation of the pressure sensor (1) in the orifice of the motor interface element (3) in a fixing direction (B) causing the sliding of the fixing lugs (5) in their respective grooves (8) and the translation of the pressure sensor (1) towards the motor interface element (3) to a fixing position. The measuring head (4) comprises a radial sealing means. According to the invention, the pressure sensor (1) comprises means (10) for holding the pressure sensor (1) in the fixing position making it possible to block the rotational movement of the latter in a direction of rotation contrary to the direction of fixing (B) when fixed on the motor interface element (3).
