  1. Pompe à engrenages (10) comprenant
    - au moins deux roues dentées (16A, 16B) s'engrenant par l'extérieur, qui s'appliquent avec leurs côtés plats contre des premier et deuxième couvercles de boîtier (14A, 14B) de la pompe à engrenages,
    - des tourillons d'arbre (184, 180) qui sont connectés de manière solidaire en rotation au moins à la roue dentée d'entraînement (16A) et qui sont supportés à rotation des deux côtés de la roue dentée d'entraînement (16A) dans le premier ou dans le deuxième couvercle de boîtier (2, 3 ; 14A, 14B),
    - un pivot d'entraînement (18A) guidé vers l'extérieur à travers le premier couvercle de boîtier (2 ; 14A), et
    - un joint d'étanchéité d'arbre (26) scellant le pivot d'entraînement (18A) par rapport au couvercle de boîtier (2 ; 14A) qu'il traverse et empêchant la sortie de liquide à pomper, lequel est disposé, sur le côté intérieur du premier couvercle de boîtier (2 ; 14A) traversé par le pivot d'entraînement (18A), tourné vers les roues dentées de pompe (16A, 16B), dans un évidement du côté de la roue dentée (24) du couvercle de boîtier (2 ; 14A), caractérisé en ce que l'évidement (24) est pourvu d'une préchambre (24A) disposée sur le côté tourné vers l'espace de pompe, de sorte que le joint d'étanchéité d'arbre (26) puisse être alimenté constamment en fluide à pomper se renouvelant.
  2. Pompe à engrenages (10) selon la revendication 1, caractérisée en ce que la préchambre (24A) s'élargit vers l'espace de pompe, de préférence de manière conique.
  3. Pompe à engrenages (10) selon la revendication 1 ou 2, caractérisée en ce que le premier couvercle de boîtier (14A) est pourvu au niveau de son côté extérieur d'une douille palier (22) supportant le pivot d'entraînement (18A).
  4. Pompe à engrenages (10) selon l'une quelconque des revendications 1 à 3, caractérisée par une chambre de lubrifiant (28A) prévue sur le côté extérieur du premier couvercle de boîtier (14A), entourant le pivot d'entraînement (18A).
