Abstract

A positive pump is disclosed which is designed for fluid foodstuffs containing solid matter, and has an inlet valve (2) and an outlet valve (5) provided with a respective first and second poppet (3, 6) reciprocated to open and close by way of a pulsed pressure supply that operates relative double acting pistons (8, 9) integral with the rear of the poppet stems each poppet is provided with a cutting edge (11, 13) which registers exactly in the relative valve seat.
