Abstract

L'invention concerne un décompresseur de construction simple, de petites dimensions et de faible coût pour moteur (1) à combustion interne à quatre temps comprenant des soupapes (9, 10) d'admission et d'échappement entraînées par des cames (27, 28) d'admission et d'échappement incorporées à un arbre (13) à cames. Le décompresseur comporte une came (38) de décompression fixée rotative sur l'arbre (13) à cames ; une roue libre (29) fixée sur l'arbre (13) à cames de façon adjacente à la came (38) de décompression pour transmettre un couple de rotation inversée à la came (38) de décompression, uniquement lors de la rotation inversée de l'arbre (13) à cames ; un limiteur (40) de couple placé entre la came (38) de décompression et la roue libre (29) ; des butées (42, 43) de décompression placées dans une partie fixe et conçues pour entrer en contact avec une partie (41) de contact formée dans la came (38) de décompression afin de bloquer celle-ci (38) en deux points de sa rotation avant et arrière ; le déplacement de la partie (38a) de came de la came (38) de décompression est réglé de façon à être supérieur au cercle de base de la came (28) d'échappement, et inférieur au déplacement maximal de la partie (28a) de came de la came (28) d'échappement, et de sorte qu'une soupape (10) d'échappement ne soit pas ouverte par la came de décompression lorsque la partie de contact de butée (43) de came de décompression est en position bloquée, pendant la rotation avant de l'arbre (13) à cames.
