Abstract
Patente de Invenção: <B>"ENGRENAGEM HIDROSTáTICA"<D>. A presente invenção refere-se a uma engrenagem hidrostática com um circuito hidráulico fechado. Ficou comprovado que tais engrenagens não podem ser operadas com precisão em virtude de folgas de componentes mas também em virtude do desgaste. Por essa razão, um dispositivo de ajuste e uma proteção contra sobrecarga são sugeridos para a engrenagem hidrostática.
