Abstract
A wellbore assembly includes a drill string and a drill bit in fluid communication with the drill string. The drill bit has a tubular wall, an internal fluid channel, a tapered tube, and a spring. The fluid channel receives and flows the drilling fluid from the drill bit bore and out the drill bit. The fluid channel includes an inwardly projecting shoulder. The tapered tube is disposed inside the fluid channel. The tube has a rim and a wall extending from and converging away from the rim in a flow direction of the drilling fluid. The spring is disposed between the inwardly projecting shoulder and the rim. The tapered tube is movable under fluidic pressure in the flow direction to compress or extend the spring. The tube pushes an obstruction in the fluid channel out of the fluid channel upon movement of the tube.
