Abstract
A piercing mechanism for a pressure vessel having a recessed membrane includes an inner housing that receives the pressure vessel and controls longitudinal movement of the vessel. The inner housing is slidably received in an outer housing, which can constrain the inner housing to reciprocating longitudinal movement therein. A pin in the outer housing configured to selectably pierce the membrane extends longitudinally through the inner housing in alignment with the membrane when the pressure vessel is received in the inner housing. A lever is actuated to initiate piercing of the membrane of the pressure vessel.
Claims19
An airgun comprising:
- a piercing mechanism for a pressure vessel having a recessed membrane, said piercing mechanism comprising:
- an inner housing configured to receive the pressure vessel and control longitudinal movement of the pressure vessel in the inner housing;
- an outer housing in which the inner housing is slidably received;
- and
- a pin in the outer housing extending longitudinally through a portion of the inner housing in alignment with the membrane and configured to selectably pierce the membrane when the pressure vessel is received in the inner housing;
- and
- a lever configured to force inner housing further into the outer housing such that the pin pierces the membrane of the pressure vessel when the pressure vessel is in the inner housing and the lever is actuated.
