摘要： A retaining assembly for a cylindrical member and support sleeve (120) in the bore of a component of a DTH. The cylindrical member and support sleeve may, for example, be a foot valve assembly for insertion into a counter bore (62) in a bit (6). The cylindrical member (120) has a cylindrical member rigidity and at least a portion of the support sleeve (125) has a rigidity greater than the cylindrical member rigidity. A gap (195) is provided between the sleeve (125) and the component bore (6) of the DTH. The cylindrical member (120) deforms in the gap, resulting in the cylindrical member being fixedly sandwiched between the support sleeve (125) and the component bore (6).

摘要： A down hole drill, includes a drill bit (40), a reciprocating piston (75) operable to deliver an impact load to the drill bit, and means for changing the frequency with which the piston delivers impact loading to the drill bit, also resulting in a change in overall power of the drill. The means for changing frequency and overall power may operate during continuous operation of the drill. The means for changing the frequency and overall power may include a valve (130) for selectively changing the effective volume of a drive or return chamber, an actuator ()140 for changing the timing of placing the drive (25) or return chamber (30) in communication with exhaust (95), or a system for changing the frequency in response to sensing an predetermined operating parameter of the drill, such as pressure or piston position.

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 disposeable 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.
