Abstract: A seismic air gun includes a body, a main chamber, two ports, several air passageways, a shuttle, a return device, and a firing device. The main chamber is within the body. The two ports are in the main chamber. The ports lie along a common axis. The air passageways connect a high pressure air source to the return device, the main chamber, and the firing device. The shuttle slides along the common axis between an open position, in which the main chamber is open, and a closed position, in which the main chamber is closed. The return device biases the shuttle toward the closed position. The firing device causes the shuttle to move from the closed position to the open position whereby pressurized air is released simultaneously from the two ports and in opposite directions.

Abstract: A sleeve air gun (10) for releasing compressed air into water. The air gun housing (12) has a chamber enclosed (16), with an end cap (20). The end cap is engaged with the air gun housing with a retainer (22) that is light weight and expedites the engagement and disengagement of the end cap and housing. The retainer can comprise a light weight ring that engages the housing and end cap. The retaininer uniquely permits larger diameter air guns to be constructed without disproportionately increasing the weight of the air gun. The larger diameter air gun expedites the discharge of compressed air from the air gun, which maximizes the acoustic pulse generated in the water.

Abstract: A wear ring assembly for an air gun includes a support ring having a receiving recess of a first length formed in a surface of an end of the support ring. An elastic ring is adjacent an end of the receiving recess. A wear ring seats in the receiving recess and is of a second length, greater than the first length, such that a portion of the wear ring overlaps the end of the support ring, thereby covering and deforming the elastic ring. The wear ring is formed of a thin, low-friction, wear-resistant plastic material having dimensions such that the wear ring does not plastically yield during installation into the receiving recess. Installation is accomplished by attaching a core tool adjacent the seal groove. The wear ring is installed with an expanding pusher tool, over the core tool and into the receiving recess.

Abstract: A seismic air gun (10) includes a body (18), a main chamber (32), two ports (48), several air passageways, a shuttle (12), a return device (66) and a firing device (96). The main chamber (32) is within the body (18). The two ports (48) are in the main chamber (32). The ports (48) lie along a common axis (A). The air passageways connect a high pressure air source to the return device (66), the main chamber (32), and the firing device (96). The shuttle (12) slides along the common axis (A) between an open position, in which the main chamber (32) is open, and a closed position, in which the main chamber (32) is closed. The return device (66) biases the shuttle (12) toward the closed position. The firing device (96) causes the shuttle (12) to move from the closed position to the open position whereby pressurized air is released simultaneously from the two ports (48) and in opposite directions.
