Abstract
A simplified inflation valve includes a base forming centrally a bore. The bore has a bottom to which a PU membrane is attached. The membrane includes at least one aperture in a location outboard the bore. An outer circumference of the membrane is fixed to the base through ultrasonic technique or die pressing. A squeezer is mounted on the base and has elasticity for elastically resuming shape after being pressed and has an interior space forming an air chamber. The air chamber has a top forming at least one through hole. The squeezer has a bottom including an outer circumferential portion forming a sealing rim, which is fixed, through ultrasonic technique or die pressing, to the base so as to form an inflation valve. The inflation valve can be connected to an air bladder, whereby through pressing the inflation valve, the air bladder can be inflated.
