The invention relates to a pressure device which maintains the raceways (48, 160 to 165) of the main moving components (3, 5, 7 and 40) of a variable compression ratio engine permanently in contact with one another and with the faces on which they rest in a cylinder case. The inventive device includes pressure means which are solidly connected to the cylinder case (100) and which exert a pressure force on a control rack (7) having a toothed segment (75) formed by teeth (74). The pressure force is applied against a support surface (78) provided on the lower part of the rack (7).
Le dispositif presseur suivant la présente invention maintenant les pistes de roulement (48, 160 à 165) des principaux composants mobiles ( 3, 5, 7 et 40) d'un moteur à rapport volumétrique variable en permanence en contact entre elles ainsi qu'avec les faces sur lesquelles elles prennent appui dans un carter cylindre comprend des moyens de pression solidaires du carter cylindre (100), qui exercent un effort de pression sur une crémaillère de commande (7) comportant un secteur denté (75) constitué de dents (74) et en ce que l'effort de pression est appliqué sur une surface d'appui (78) aménagée sur ladite crémaillère (7) en sa partie inférieure.
