Abstract: A manually-operated device for safely inflating automotive vehicle tires. A pressurized gas cylinder is connected to a manual valve for delivery of pressurized gas to a vehicle tire. The gas pressure is safely controlled (regulated) by a stepped piston that is slidably arranged in a vent chamber. A small diameter rod section of the piston is aligned with a valve seat in the main flow passage. Pressure rise on the large diameter section of the piston causes the rod section to temporarily interrupt the main gas flow. Gas is vented around the large diameter section of the piston to enable the rod section to move away from the associated valve seat, thereby permitting gas flow to resume through the main passage.

Abstract: A gas inlet including an inlet body having a gas passage, a tube body and a plug body, wherein the tube body and plug body are connected to the inlet body via a thin strip. The tube body has a close end and a cut and is suitable to be fitly fitted into the gas passage, while the plug body is suitable to be plugged into the tube body, whereby by means of plugging or removing the tube body and plug body, an inflatable product can be rapidly inflated or deflated.

Abstract: A specific arrow for fishing in shore, the arrow is shot farther from shore by a bow for a good catch of fish. It provides a closed arrow sleeve tube connected to the body of an arrow and a ring is positioned at the front end of the closed arrow sleeve tube, the ring can spin relative to the closed arrow sleeve tube to prevent the body of the arrow from becoming entwined by fishline.
