Abstract

A non-cylindrical nozzle socket and a downhole tool that includes a non- cylindrical nozzle socket. The non-cylindrical nozzle socket includes a base and a nozzle socket wall that extends outwardly from the base. The nozzle socket wall includes a distal end positioned away from the base. The distal end forms an opening larger than the area of the base.
