Latest Patents

Ekwall holds a patent for a "Compressed air percussive mechanism for a down hole hammer." This pressure-air driven percussion device is designed for down-the-hole drilling. It features a hammer-piston that is axially reciprocally movable within a hammer-piston chamber. The hammer-piston operates by acting against the upper end of a drill bit, which is securely positioned inside a chuck. An air-cushion is formed at the hammer-end of the hammer-piston to reduce percussive power when the drill bit moves past a predetermined distance in the percussion direction. The drill bit is sealingly supported in a drill bit bushing, ensuring that the hammer-end of the hammer-piston cooperates sealingly with the drill bit bushing to form the air-cushion.
