ABSTRACT:
An hydraulic nut including an annulus, typically of stainless steel, having an annular cavity therein. The cavity is sealed pressure-tight by an annular deformable membrane of the same material as the annulus which is welded to the annulus about the cavity by a fusion weld. An hydraulic fluid, under pressure, typically grease, is injected into the cavity. The membrane is backed up by an annular shoe and the force produced by the pressure is transmitted through the membrane and the shoe to the object to which the force is applied. Very high forces may be applied by this apparatus.
