Abstract

Inventia se refera la o/un pompa motor hidraulic cu roti dintate, montate pe niste arbori, care în functie de sensul de curgere a fluidului, pot fi rotiti în ambele sensuri. Pompa motorul, conform inventiei, este caracterizat prin aceea ca pe niste suprafete laterale ale unor lagare în care sunt montati niste arbori fixati de un corp, sunt practicate cate doua dintre niste locasuri cu contur deschis spre o cavitate, sittuate fata în fata plasate între niste camere de compensare, niste portiuni de perete superioare, împreuna cu niste portiuni de perete inferioare, care delimiteaza locasurile fiind situate într-un acelasi plan cu niste portiuni de perete laterale care marginesc niste locasuri superioare cu contur închis, practicate în niste capace si respectiv cu niste portiuni de perete laterale care marginesc niste locasuri inferioare cu contur închis, prevazute de asemenea în capace, în toate locasurile amintite fiind dispuse niste garnituri elastice.
