Unidirectional valve, especially applicable to inflatable bodies, characterized by comprising a tubular envelope, inside which fits through a corresponding set of longitudinal ribs, being able to move freely in axial direction, with minimal friction, a piston that it is able to support itself, by making the closure, against a corresponding step or internal seat provided in the said tubular body, being constantly driven to adopt this position by the action of an appropriate elastic force, and being able to be separated from it by the own pressure of the injected fluid, which can then circulate along the tubular envelope, passing through the annular chamber determined by the clearance existing between this envelope and the piston.
