Abstract

L'invention concerne une pompe à engrenages, comportant : un boîtier ayant, en son sein, une chambre de stockage d'engrenages destinée à stocker une paire d'engrenages ; une plaque latérale mobile ayant une rainure d'entrée haute pression dans une région côté haute pression d'une surface coulissante, qui est la surface d'un côté qui repose entre le boîtier et les engrenages et qui fait face aux engrenages ; et un joint qui est prévu sur une surface non coulissante, qui est la surface du côté opposé au côté faisant face aux engrenages de la plaque latérale mobile et qui sépare l'espace entre la surface non coulissante et le boîtier en un côté haute pression et un côté basse pression ; une concavité formant membrane liquide étant prévue dans la région où le côté basse pression passe au côté haute pression dans la surface coulissante de la plaque latérale mobile, afin de supprimer la rupture de membrane liquide entre les engrenages et la plaque latérale mobile et l'usure anormale qui se produit lors d'une telle rupture.
