ABSTRACT:
Means are provided to introduce pressurized fluid from a source into an intermittently rotated machine tool such as a chuck while the tool is stationary. The means includes a stationary annular shell surrounding a portion of the tool and radially spaced a short distance from the surface of the tool. The inside of the shell has a channel which seats an annular flexible U-shaped seal the radially outer ends of the legs of which are rigidly secured to the shell. The inner face of the seal is a web having a relatively stiff center band which, under fluid pressure is forced to shift into contact with the surface of the tool to form a seal on each side of a groove in the tool's surface. A restricted opening permits fluid from the inside of the seal to be introduced into the groove to supply the tool.
