Abstract
An air gun includes a pressure relief valve in the pump piston for relieving excess air pressure. The valve is movably mounted on the piston for movement between a closed position in which the valve seals the pressure release opening in the piston and an open position in which air can flow through the pressure relief opening in the piston. A biasing mechanism is also provided for resiliently biasing the valve towards the closed position.
