Abstract

L'invention concerne les commandes hydromécaniques. La machine hydromécanique faisant l'objet de l'invention est du type comportant un carter 1, un distributeur 8 de fluide moteur pourvu d'orifices de refoulement 11 et d'aspiration 12 et dont l'une des faces, de forme sphérique, est adjacente au bloc-cylindres 7 et dont la face opposée est adjacente directement au carter 1, ainsi qu'une commande de déplacement du distributeur 8 le long d'un guide 14 monté sur le carter, et est caractérisée notamment en ce que la face latérale du distributeur 8 qui est orientée vers le guide 14 comporte une cavité 13 communiquant avec une source de pression pulsatoire de fluide moteur pour engendrer une force supérieure à la force sollicitant le distributeur 8 vers ledit guide lors de l'interaction dudit distributeur avec le bloc-cylindres. L'invention peut être appliquée notamment aux excavateurs à commande hydraulique des organes de travail.
