Patent ID: 7398777

Claim:
A mechanism for a paintball gun comprising a valve operating between telescopic components of a paintball gun mechanism to control communication between a source of pressurised fluid and an outlet by means of at least one axially elongated opening in a first of the components which is axially displaceable relative to an O-ring seal associated with a second of the components between a retracted position, in which the source of pressurised fluid and the outlet are in fluid communication, and a firing position, in which the source of pressurised fluid is isolated from the outlet, wherein the at least one opening extends about a minor portion of the circumference of the first component such that when the O-ring seal is aligned with the at least one opening to open communication between the source and the outlet, the O-ring seal is supported by an outer peripheral surface of the first component on opposite circumferential sides of the at least one opening.
