An improved hydraulic fuse to control hydraulic fluid flow through the fuse comprising an outer body; an annular metering body cylinder within the outer body and defining a bore, and a flow control port, whereby a flow path A is defined between the outer body and the metering body cylinder and to the port; a piston slidable longitudinally in the bore to control flow through the port; first and second flow control members which are relatively slidable longitudinally in the outer body, and in the paths of fluid flow to the port, and to the piston; a threshold spring urging the first member in one direction longitudinally and a metering spring urging the second member in the opposite direction longitudinally; the members and springs cooperating to effect forward flow to the flow control port along path A as forward flow increases to level at which a portion of the flow is diverted to a path B to act on the piston, causing the piston to move toward the flow control port and to close the port.
