(a) Technical Field of the Invention
The present invention is generally related to gas control valves, and more particular to a touch-type gas control valve that instantly releases highly pressurized gas.
(b) Description of the Prior Art
For a conventional touch-type gas control valve, simple and robust structure is particularly required, considering its usage frequency and restoration speed, so as to meet realistic requirement. Lower production cost and convenient maintenance are also of concern to the manufacturers of the gas control valve. In addition, if the gas control valve is applied as a vital component in an intensely operated apparatus, such as a game rifle, the security, robustness, and effectiveness of the gas control valve should be even more important.
The present invention therefore provides a novel touch-type gas control valve. By touching a button which engages a stem to open an inlet, highly pressurized gas immediately floods a body of the gas control valve, and then spurts out of a number of outlets perpendicular to the inlet.
The touch-type gas control valve contains a button, a spring, a hollow body, an O-shaped ring, and a stem. The body contains, from top to bottom, a flange, a bulging middle section, a lower section; a plurality of outlets around the lower section's circumference, and an inlet on a bottom side of the body.
The button is configured to be slidable in and out of a top side of the body.
The spring is housed inside the body, having a top end against a bottom side of the button and a bottom end against the bottom side of the body.
The stem has a stem body, a semi-spherical head at a bottom end of the stem body, and threads around a top section of the stem body. The stem runs through the ring, into the body through the inlet, through the spring, and is fastened into the bottom side of the button.
The ring is positioned around the inlet and is sandwiched between the semi-spherical head and the bottom side of the body by the resilience of the spring when the button is not depressed.
The foregoing objectives and summary provide only a brief introduction to the present invention.
