Abstract
L'invention porte sur des pompes/moteurs hydrauliques de petite taille munis de pistons dont le corps est sensiblement aussi long que le corps de leurs cylindres respectifs, et dont les cylindres comportent des lumières de graissage, circulaires et radiales obturées en permanence par les corps des pistons sur la totalité de leur course, et reliées entre elles pour former à l'intérieur du bloc de chaque cylindre un canal unique ne présentant ni entrée ni sortie mais uniquement alimenté par soufflage à partir des soupapes des cylindres. Plusieurs joints placés au voisinage de l'extrémité ouverte des cylindres éliminent pratiquement les pertes des susdits passages, améliorant ainsi le rendement volumétrique. La lubrification améliorée résultante, associée à des dispositifs abaisseurs à ressort exclusifs permet s'utiliser des plateaux oscillants à inclinaison variable ne requérant ni de biellettes aux extrémités extérieures des pistons, ni les plateaux usuels à nutation seule.
