Claim:
A control valve for an inflatable apparatus comprising a horn-like body having a front; a rear; a center; a central portion; a chamber defined in the rear and having an inner wall; a tubular part defined in the central portion of the horn-like body concentrically around the center, having an inner wall and communicating with the chamber; and two recesses defined respectively at diametrically opposite sides of the inner wall of the tubular part; a seat mounted on the rear of the body and having a central portion; an outer edge; a rear surface; a front surface; a primary outlet formed through the central portion of the seat, communicating with the chamber and having a diameter; a secondary outlet formed through the seat between the primary outlet and the edge, communicating with the chamber and having a diameter and a secondary valve seat having an outer diameter larger than the diameter of the secondary outlet and attached concentrically outside the secondary outlet, a central through hole, an outside surface and an inside surface; an inlet formed through the seat between the primary outlet and the edge and diametrically opposite to the secondary outlet and communicating with the chamber; a discharge nozzle mounted on the rear surface of the seat around the secondary outlet; at least two hollow poles formed on the front surface of the seat; at least two first resilient members mounted respectively in the hollow poles; and a cover movably mounted inside the body and having a rear; an inside; a center; an outside surface; a radial flange formed at and extending radially out from the rear of the cover, having an outer edge and mounted in the chamber in the horn-like body; an O-ring mounted between the outer edge of the radial flange of the cover and the inner wall of the chamber in the horn-like body; two rods formed on the rear of the cover, mounted respectively in the hollow poles and abutting the first resilient members; a secondary shaft formed longitudinally on the inside of the cover, aligned with the secondary outlet, movably extending into the discharge nozzle and having a distal end and a secondary valve disk mounted on the distal end of the secondary shaft in the discharge nozzle to open and close the secondary outlet, a primary shaft formed longitudinally on the inside of the cover at the center, aligned with the primary outlet and having a distal end; and a primary valve disk mounted on the distal end of the primary hollow shaft and a primary valve seat to selectively close and open the primary outlet; two notches defined on diametrically opposite sides of the outer surface of the cover; two buttons movably mounted respectively in the notches and respectively having a distal end and a barb formed on the distal end and engaging the corresponding recess, and two second resilient members radially mounted respectively in the notches and abutting and pressing the buttons out radially.
