摘要
Improved anti-return arrangement for pneumatic pumps, essentially characterized in that the spigot protruding from the impulsion chamber towards the introduction area of the valve of the tubular, comes from the bottom of the aforementioned chamber based on a vertical nerve as a wall made in the inside the chamber, which reinforces the consistency of said spiral, and because the housing for the rubber element in complement adjacent to the chamber, presents a lateral recess as a circular pocket which is occupied by the material of the element when resting on it the tubular valve constituting an auxiliary side seal of the rubber against the side of the above-mentioned valve body.
