ABSTRACT:
A frangible hydraulic fuse includes a fitting secured to a sleeve by a plurality of frangible pins. In normal operation, hydraulic fluid flows through the fuse through radial ports of a sleeve to which the fitting is engaged by the frangible pins. A compression spring urges a poppet slideably positioned in the sleeve to a position out of engagement with the radial ports. Upon rupture of the frangible pins, the fitting is released and hydraulic fluid may flow unimpeded through the radial ports creating a pressure drop which causes the slideable poppet to move to a position overlying and closing the radial ports.
