摘要： A bit assembly is for a percussive drill that includes a casing with an interior chamber and includes a bit connectable with the casing and having a longitudinal bore and an axis through the bore. The bore has a retainer portion with one or more generally. conical inner surfaces extending circumferentially about and facing generally toward the axis. A generally cylindrical valve has a longitudinal passage with an inlet fluidly connectable with the casing chamber and an outlet fluidly connectable with the bit central bore and an axis through the passage. An engagement portion with at least one generally conical outer surface extends circumferentially about and faces generally away from the valve axis. The valve engagement portion is disposable within the bit bore retainer portion such that the valve conical outer surface is disposed within and against the bit conical inner surface to retain the valve coupled with the bit.

摘要： A piston for a fluid-actuated, percussive, down-the-hole drill is provided with self-lubricating bearings and self-lubricating seals. The piston includes an elongated body member terminating in a front end and a back end and having a longitudinal bore therethrough. A bearing and seal combination is positioned adjacent each end of the piston and an undercut portion of the piston body extends therebetween. The bore and undercut portions of the body form a portion of fluid passageways in the drill, when the piston is reciprocated in the drill. The seals float in their grooves, being movable axially, radially and circumferentially. The bearings are substantially nonmovable axially and radially.

摘要： A device for use within a backhead of a down-the-hole percussive drill, for removing debris from a drillhole, includes a separator for separating water and other matter from the percussive fluid prior to the percussive fluid actuating the piston of the drill. The water and other matter are exhausted out the drill bit, to remove the debris. The device includes a one-way flow valve to prevent backflow of debris and water into the drillhead during periods when the percussive fluid flow ceases. The device can be added to existing drill backheads, or included as part of newly manufactured units.
