Description
- 1. Field of the Invention
- The invention relates generally to devices for distributing compressed gas from high pressure gas reservoirs, and more particularly to an arrangement for relieving pressure in such devices prior to disconnection of the high pressure gas reservoir.
- 2. Description of the Related Art
- Gas powered projectile launching devices used in the game of paintball are well known. These gas powered devices (otherwise known as paintball markers) employ portable compressed gas cylinders to supply the necessary pneumatic power. The compressed gas is most commonly compressed air or compressed carbon dioxide. Increasing the amount of compressed gas that can be connected to a paintball player's marker has been the object of much development in the field of paintball markers.
- One recent trend is toward the use of very high pressure compressed gas cylinders. These cylinders increase the quantity of available compressed gas by storing the gas at pressures in the range of 4,500 to 5,500 p.s.i. These very high-pressure gas storage cylinders typically include a first regulator built into the cylinder, which releases gas from the cylinder at a pressure of approximately 800 p.s.i. Gas at this pressure is fed through a distribution device and associated plumbing to a second regulator on the marker where the pressure is further reduced to a range of between 50 and 100 p.s.i. for use by the marker. The very high pressure storage cylinder typically includes a threaded coupling which is threadably received by the device for distributing pressurized gas from the cylinder to the regulator attached to the paintball marker. These distribution devices typically include a control knob attached to a threaded shaft that allows axial manipulation of a pin for depressing a valve pin on the compressed gas cylinder. When the compressed gas cylinder is threadably coupled to the gas distribution device, the control knob is rotated such that the pin is axially moved toward the gas cylinder. The pin depresses the cylinder valve pin and releases compressed gas from the cylinder into the distribution device which communicates with passages and tubes leading to the regulator of the paintball marker. When the cylinder valve pin is depressed, the internal passages of the distribution device and the tubes leading to the paintball marker are pressurized at approximately 800 p.s.i.
- When the paintball marker is not being used, it is desirable to remove the compressed gas cylinder from the paintball marker so that it may be stored and/or refilled. Commonly, the compressed gas cylinder is not completely exhausted and therefore the gas distribution device and associated plumbing are filled with compressed gas at approximately 800 p.s.i. This is true even after the control knob has been rotated to withdraw the pin away from the compressed gas cylinder and release the valve pin of the cylinder shutting off flow from the cylinder to the gas distribution device and associated plumbing. The pressure in the distribution device and plumbing complicates removal of the compressed gas cylinder by exerting pressure on the threads of the cylinder/device coupling. This pressure increases the difficulty of the unthreading the cylinder from the coupling. Further, the compressed gas in the device and associated plumbing presents the hazard of explosive release of the cylinder from the coupling. Such explosive release can harm the user and/or damage the costly and fragile gas reservoir.
- Thus, it is necessary to relieve pressure in the gas distribution device and associated plumbing prior to removal of the compressed gas cylinder. This has been accomplished by cycling the paintball marker several times after shutting off gas flow from the cylinder. As a safety feature, the coupling of the distribution device may be provided with a vent hole positioned to vent pressure from the distribution device before the threaded connection between the reservoir in the coupling is completely released. The vent prevents the explosive release of gas during removal of the reservoir from the coupling.
- There is a need in the art for a gas distribution device that enhances the convenience and safety of removing a high-pressure gas reservoir from a paintball marker.
- Briefly stated, the invention is a gas distribution device including an exhaust hole that is uncovered by backing off the control knob to bleed pressurized gas from the distribution device and the associated plumbing. The improved gas distribution device provides a simple, safe and convenient means of controlled pressure relief without cycling the marker or removing the compressed gas cylinder. According to aspects of the present invention, the distribution device includes a coupler configured to receive and mate with a compressed gas cylinder. The device defines a high-pressure chamber having at least one pressure port for distributing pressurized gas to the paintball marker or other pneumatic equipment. The device includes a control knob attached to a threaded shaft which is threadably engaged in an end of the device opposite the coupling. The shaft extends to a pin configured and positioned for depressing and releasing the valve pin of the compressed gas cylinder. Rotation of the control knob in a first direction moves the pin toward the cylinder to depress the valve pin and pressurize the system. Rotation of the control knob in a second direction withdraws the pin away from the cylinder, releasing the valve pin and shutting off gas flow.
- A feature of the present invention relates to an unthreaded portion of the bore in which the actuator travels. The shaft of the actuator is provided with a circumferential groove and a seal compressed between the shaft and the inside surface of the unthreaded portion of the bore. The exhaust hole communicates with the actuator travel portion of the bore at an axial position selected to facilitate venting of gas from the device after the valve pin of the compressed gas cylinder has been released. The control knob is rotated in the second direction to release the valve pin and shut off flow of gas from the reservoir. To vent the system the user simply continues rotating the control knob in the second direction until the seal on the shaft axially uncovers the exhaust hole. Pressurized gas from the distribution device and associated plumbing is released in a controlled manner through the exhaust hole.

The vent position is achieved by counter rotation of thecontrol knob 32 from the “off” position shown inFIG. 3 . The vent position permits a controlled release of pressure from thegas distribution device 10 and associated plumbing without cycling thepaintball marker 30 or removing thecompressed gas cylinder 20. -
