ABSTRACT:
A seismic air gun has a passage between the stem of its shuttle and a baffle, whereby ambient pressure can reach the back of the operating piston. The gun is fired by dumping a small quantity of pressure air from the operating chamber via a solenoid valve to the ambient surroundings. The firing seal is a lip seal. The shuttle is of unitary construction, while the baffle is diametrically split.
