ABSTRACT:
A control valve for an air pressure bar includes a valve cap having an annular groove in a outer surface, a valve body having an annular ridge and an aperture in an annular wall, a valve base and a pin rod. The aperture producing elasticity to let the valve body combined tightly with the valve cap and a stepped notch in an annular wall below the upper center cavity of the valve body form an air passageway for gas to flow through. The valve body and the valve base are combined together by an annular ridge on an inner surface of a lower center cavity of the valve body and an annular groove in an outer surface of the valve base. The valve base has a stop on an inner surface of a center hole to stop a bottom of the pin rod not falling out of the valve body.
