Abstract: An apparatus for detecting the position of the paintball of a paintball gun includes an induction plate responsive to electrostatic capacity. The induction plate is positioned at a corresponding side of the ball-falling tube within the firing area of the gun barrel, and the induction plate consists of a conductive terminal piece and equivalent electrostatic capacity. An insulated body is interposed between the terminal piece and the gun barrel. Besides, an electrostatic capacity detection circuit is electrically coupled to the induction plate for detecting the change of the electrostatic capacity of the induction plate. Moreover, the signal of the change of the electrostatic capacity is transmitted to the paintball-firing circuit for a reliable detection if the paintball accurately reaches the firing area such that the push tube may be actuated in accordance with this information. In this way, an accurate detection is ensured without being disturbed by other light sources.

Abstract: A pneumatic pusher having a main body, a flow-guiding body, a moving body, and a delivery tube. The flow-guiding body includes a front tube with a smaller diameter and a rear tube with a larger diameter. The delivery tube is mounted on the front tube in such a way that the outer wall of the delivery tube and the inner wall of the main body define a return pressure chamber. A first gas-distributing channel extending from a first air outlet at one side of the main body leads directly to the inner side of the delivery tube. The side of the first air inlet of the main body communicates with a second gas-distributing channel. The second gas-distributing channel includes an exit located at one side of the return pressure chamber of the delivery tube. The air pressure provided through the second gas-distributing channel serves as cushioning force in pushing the delivery tube outwardly.

The pneumatic delivery mechanism comprises a flow-guiding body forming a major air channel at front end and a flow-guiding chamber at rear end thereof, a flow-guiding movable body utilizing a valve body to divide the flow-guiding chamber into a front and a rear air pressure chamber with different pressure area and a delivery tube placed around a tube at front part of the flow-guiding body. Moreover, a stopper controls the opening or closing of air flow channel, thereby changing the pressure difference between the front and the rear air pressure chambers. The delivery tube is shifted forward by a small amount of air flow fed into a minor air channel for pushing a paintball a little forward. Thereafter, the paintball is discharged by thrust of air flow into the major air channel.

Abstract: An improved structure of a pressure regulator including a body and an adjusting device. The adjusting device includes a retractable bent in shape from a metal material and provided on an upper side of the body. The secondary pressure in the interior of an enclosed space defined between the retractable tube and upper and lower plates is utilized to act in a stable and uniform manner on the upper plate to thereby change the length of the retractable tube and bring a valve plug to elevate so as to control high pressure gas flowing from a primary pressure chamber to a secondary pressure chamber. By means of the elasticity of the retractable tube that coordinates with the pressure of the gas, the output of secondary pressure can be stable and precise without being affected by the pressure different caused by change in the internal pressure of the container (steel cylinder), thus having the advantages of extended service life and enhanced safety.
