Gas supply regulator for an air gun |
摘要 |
A charging valve for the pressure regulator of a pneumatic-type air gun comprises a closure element (50) in the form of a steel ball which is arranged to become accommodated within an elastomeric O-ring (48) to close the valve. The ball is of slightly greater diameter than the internal diameter of the O-ring, whereby a seal is created between the ball and an interior external surface of the O-ring at its inner circumference. A piston-operated plunger (60) in a gas outlet passage (44) pushes the ball through the O-ring in order to open the valve, the ball being received into a bore (56) of a bushing (54) which contains a retaining spring (58) to limit movement of the ball away from the O-ring. |
