Abstract

Watertight liquid sealing device to prevent the passage of liquid between a rotatably mounted shaft and an orifice, through which the shaft extends with working clearance, including an annular support projecting from the shaft, means adjacent to the shaft formed by a wall cylindrical in which the support is rotatable with working clearance, a spiral groove extending around the periphery of the annular support, and closing means for the cylindrical wall adjacent one end of said annular support, said closing means defining said orifice through which the shaft with working clearance extends, wherein the rotation of the shaft, in a given direction, will cause the spiral groove to resist the passage of liquid between the annular support and the core, and will make it possible for the annular support and the closing means, cooperate and thereby prevent the passage through the clearance between the shaft and the orifice of any residual liquid that overcomes the resistance of the liquid. To spiral groove. (Machine-translation by Google Translate, not legally binding)
