Abstract

L'invention concerne une pompe à eau présentant un boîtier contenant une enveloppe interne contenant, à son tour, un siège de soupape présentant une pluralité de soupapes espacées. Un passage d'écoulement est formé entre l'enveloppe interne et le boîtier. Lorsque le liquide est aspiré dans le boîtier, il s'écoule dans l'enveloppe interne à travers le passage et est déchargé du boîtier par l'intermédiaire du siège de soupape qui tourne à vitesse élevée. Le passage fournit un espace d'amortissement pour l'écoulement du liquide dans le boîtier de sorte à assurer un écoulement régulier sans à-coup, même en cas de réduction de l'épaisseur complète de la pompe à eau. Ainsi, le niveau d'aspiration de la pompe à eau est maintenu fixe, ce qui évite l'apparition d'érosion des orifices de la pompe à eau et maintient, de ce fait, l'efficacité de la pompe à eau.
