Valve for air pumps, characterized essentially by the fact that it consists of a tubular sleeve that projects towards the inside of the body of the pump, whose sleeve is open at its outer end and closed inside by a bottom of less thickness than the rest and which forms body with the sleeve itself, which is cut along its perimeter with the exception of a section that constitutes an articulation zone thereof, so that it acts as a sleeve operculum.
