Abstract
Liquid aspirator, characterized by being constituted by a casing of substantially cylindrical shape in which one of its bases is open to allow the coupling of a cover adjusted by means of screws, and the opposite base provided with a neck of smaller diameter, in which fits a bushing with suitable bearing for installation of an axle on which a rotor is mounted integrally fitted perfectly a. The inner surface of said casing, there being two lateral mouths spaced 90ยบ apart, and leaving the internal profile between both mouths with a step at the level of one of them and a projection limited by arcs in the middle area of said space, in order to achieve a special retention of the rotor blades when passing through this sector.
