Title: (EN) SELF-DRIVEN PUMP DEVICE
(FR) DISPOSITIF DE POMPAGE AUTOMATIQUE
Abstract: front page image
(EN) ABSTRACT OF THE DISCLOSURE An apparatus for delivering fluid with a relatively constant, controlled rate of flow comprises a vacuum power means, a fluid storage means in axial alignment with the vacuum power means and a plunger means carried by the vacuum power means and in axial communication with the fluid storage means. The plunger means is driven by a vacuum which collapses under atmospheric pressure, and as it is driven it effects delivery of the fluid from the fluid storage means.
