ABSTRACT:
There is provided a stop valve-carrying rotary nozzle for a machine tool designed to eject a fluid onto the portion of a work which is being worked thereby improving the work-cooling and cutting efficiency of the machine tool.
The present rotary nozzle consists of a nozzle body having a throughbore and a spherical member having a throughbore that is in turn fitted within the fluid outlet side of said throughbore of the nozzle body with a sealing O-ring being interposed between the spherical member and the throughbore of the valve body, while allowing a free rotation of the spherical member on its own axis therein. Upon the spherical member having been fitted within the throughbore of the valve body, the annular edge of the valve body is inwardly bent by calking to surroundingly engage the outer half surface of the spherical member, while a portion of the thus inwardly bend annular edge is provided a recess longitudinally extending above and beyond the center of the spherical member and having a width slightly greater than the diameter of the throughbore of the spherical member so that when the rotary nozzle is to be made inoperative, a rod like plug is inserted from outside into the opening mouth of the throughbore of the spherical member and then moved together with the thus fitted spherical member until the plug is inserted between said recess.
