摘要： A multi-stage diffuser nozzle for use as a drill bit nozzle jet includes a flow restriction portion upstream of a fluidic distributor portion, and also preferably includes a transition region between these two. The flow restrictor communicates with the interior fluid plenum of a drill bit and is used to limit or restrict the total flow of drilling fluid by having a relatively small cross-sectional area for fluid flow. The fluidic distributor communicates with the flow restrictor and reduces the exit flow velocities of the drilling fluid as the drilling fluid is ejected from the nozzle by providing a relatively larger cross-sectional area for fluid flow. The fluidic distributor also directs the flow paths of the drilling fluid to locations such as cone surfaces that are prone to bit balling. The transition region is an area that dampens fluid pressure oscillations in the drilling fluid.

摘要： Enhanced inserts are formed having a cylindrical grip and a protrusion extending from the grip. An ultra hard material layer is bonded on top of the protrusion. The inserts are mounted on a rock bit and contact the earth formations off center. The ultra hard material layer is thickest at a critical zone which encompasses a major portion of the region of contact between the insert and the earth formation. Transition layers may also be formed between the ultra hard material layer and the protrusion so as to reduce the residual stresses formed on the interface between the ultra hard material and the protrusion.

摘要： A nozzle sleeve for the retention of replaceable fluid nozzles for rock bits is disclosed. The sleeve is secured within the body of the rock bit. A first upstream end of the sleeve communicates with a fluid plenum formed by the bit body. A second downstream end of this sleeve is adapted to receive the fluid nozzles. An elliptical fluid entrance is formed at the first upstream end of the nozzle sleeve. The elliptical fluid inlet formed by the sleeve serves to increase the flow of fluid to the nozzles, reduce turbulence of the fluid and substantially reduce the erosive effects associated with high fluid velocities and turbulent flow.
