Abstract:
The invention provides a priming pump comprising a deformable envelope associated with an inlet endpiece and an outlet endpiece each fitted with a moving valve member, the endpieces being arranged in such a manner that when the valve members are in the closed position, the outlet endpiece presents a leakage rate that is greater than the leakage rate of the inlet endpiece.
