摘要： In one aspect of the invention, a system for removing a layer of a paved surface includes a vehicle adapted to traverse a paved surface in a selected direction. A milling drum attached to the vehicle may be adapted to rotate around an axle substantially normal the selected direction of the vehicle. A moldboard may be positioned rearward of the milling drum and also connected to the vehicle. The moldboard may comprise an end that is adapted to push aggregate removed from the paved surface in the selected direction. A plurality of nozzles may be disposed proximate the end of the moldboard which may also be in communication with a fluid reservoir through a fluid pathway.

摘要： In one aspect of the invention a degradation drum comprises a generally cylindrical body comprising inner and outer diameters. At least one degradation assembly is disposed on the outer diameter and it comprises a holder and a pick shank secured within a bore of the holder. At least one lubricant reservoir is disposed within the inner diameter and is in fluid communication with the bore of the holder through a fluid pathway. In some embodiments, the lubricant reservoir maintains a fluid pressure on the pick shank.

摘要： In one aspect of the invention a drill string has a rotary valve disposed within its bore. The valve has a first disc attached to a driving mechanism and a second disc axially aligned with and contacting the first disc along a flat surface. Each disc has a port adapted to align with each other periodically when the discs rotate relative to one another. The aligned ports are adapted to direct fluid to at least one nozzle disposed in a working face of a drill bit of the drill string.
