Abstract
A bellows-inflator of pneumatic mattresses, rafts, rubber canoes and the like, characterized by two round pieces of sheet metal or rigid plastic, one of which, the bottom, carries in its internal part another embedded piece that in its central part has a conical frustoconical concavity that with the other piece forms a chamber that facilitates the realization of a valve formed by a hole of circular shape covered by a piece of gummed tissue, so that the air that has passed to the object that is swelling, does not can return to the bellows.
