ABSTRACT:
A nozzle retention receptacle for rotary cone rock bits consists of a nozzle retention receptacle body forming a fluid passage therethrough. The body forms a first upstream entrance end that forms part of a wall of a plenum formed within a rock bit body and a second downstream exit end. The upstream end further forms a mounting interface that circumvents a fluid entrance port to the passage in the nozzle retention receptacle. The port communicates with the fluid plenum in the bit body. The body of the rock bit further forms a nozzle retention receptacle mounting interface that is common to the mounting interface formed by the nozzle retention receptacle.
