Abstract
High pressure compressed gas pressure vessels and devices utilizing such vessels are disclosed herein. More particularly, aspects of the present invention are directed to high pressure (i.e., nitrogen or N2 based) pressurized gas cylinders with pierceable membranes recessed from the opening of the pressure vessel such that prior art piercing mechanisms cannot pierce the membrane for safety purposes. Additionally, aspects of the present invention are directed to pressurized gas operated devices with elongated pins for piercing pressure vessels with recessed pierceable membranes.

Abstract
A pneumatic arrow gun has a gun body, an arrow, a positioning sleeve, and a connecting wire. The arrow is for inserting into an air tube of the gun body. The positioning sleeve is temporarily mounted around the air tube, and the arrow is disposed through the positioning sleeve. The connecting wire connects the gun body to the positioning sleeve. Because the positioning sleeve is temporarily mounted around the air tube, the arrow slides forward relative to the positioning sleeve after triggering. When triggering the arrow, the connecting wire naturally dangles. When the arrow detaches from the air tube, the positioning sleeve located at a nock of the arrow due to the sliding of the arrow. Therefore, a rebound of the arrowhead is prevented. The safety and the shooting stability are ensured. Further, the arrow is easily retrieved by the connecting wire.

Abstract
A pressure regulator has a valve tube assembly, a gas-input assembly, a first regulating assembly and a second regulating assembly. The gas storage device has a storage unit and the pressure regulator. By the first and the second regulating assemblies, the effect of adjusting down the gas pressure is achieved to maintain the safety of use. The pressure regulator is partially embedded in the gas storage unit to reduce the overall volume of the gas storage device. However, the high-pressure piston chamber of the valve tube assembly communicates with the outside of the gas storage unit through the high-pressure gas channel to maintain the normal operation of the elastic element in the high-pressure piston chamber.

Abstract
An automatic injection device for fluid has a sleeve, an actuating unit, a barrel with a piercing needle and a high-pressure air source. The high-pressure air source is mounted slidably in the barrel. The actuating unit is mounted in the sleeve and barrel and selectively blocks the high-pressure air source. When the user needs to release the high-pressure air in the high-pressure air source, the user press the actuating unit to allow the high-pressure air source to slide until the high-pressure air source hits the piercing needle. Therefore, the high-pressure air in the high-pressure air source is easily released by actuate the actuating unit without additional hand tools.

Abstract
A compressed gas supplier has a power-free decompression device and an expansion chamber. The power-free decompression device decompresses a gas in a high-pressure source into a decompressed gas. The expansion chamber connects to the power-free decompression device and receives and stores the decompressed gas. The pneumatic tool is driven by the decompressed gas in the expansion chamber. Thus, the compressed gas supplier for the pneumatic tool is small and easy to be carry. In addition, the decompressed gas stored in the expansion chamber is also benefit for supplying decompressed gas to the pneumatic tool that needs much gas to drive.

An automatic injection device for fluid has a sleeve, an actuating unit, a barrel with a piercing needle, a high-pressure air source and a driven unit. The actuating unit is mounted in the sleeve. The high-pressure air source and the driven unit are mounted slidably in the barrel. The barrel, the high-pressure air source and the driven unit are first mounted in the sleeve to be ready for use. When the user needs to release the high-pressure air in the high-pressure air source, the user press the actuating unit to drive the driven unit to slide. Then the driven unit also drives the high-pressure air source to slide until the high-pressure air source hits the piercing needle. Therefore, the high-pressure air in the high-pressure air source is easily released by actuate the actuating unit without additional hand tools.

Abstract
An adjustable pressure valve has a valve body, an inactive cap and an active cap. The inactive cap is mounted in the outlet of the valve body, abuts against the piston in the valve body and has an inclined edge. The active cap is mounted rotatably against the inactive cap and has an inclined edge abutting against the inclined edge of the inactive cap. When the active cap is rotated relative to the inactive cap, the inactive cap is pushed by the inclined edge of the active cap to slide inwardly or outwardly. Then the elastic element in the valve body is compressed more or less by the slide of the active cap to adjust the preset outlet pressure without disassembling the adjustable pressure valve.

Abstract
A pressure regulator has a main body, a piston, an elastic element and an adjusting element. The main body has an inlet and an outlet. The piston is mounted movably between the inlet and the outlet. The elastic element is mounted in the main body to prepossess that the piston to move toward the outlet of the main body. The adjusting element is mounted adjustably in the main body and selectively abuts against the piston to selectively close a flow path from the inlet to the outlet. Adjusting the position of the adjusting element results influences the compressed length of the elastic element. Therefore, the preset outlet pressure is fine-tuned.
