Title: Hydraulic fuse with pressure regulator

Abstract

This paper describes an improved hydraulic fuse to monitor the quantity of hydraulic fluid passing through the fuse, and then block such flow when a selected quantity of fluid has passed through the fuse. It comprises: a body structure containing cavity structure, a primary piston in the cavity structure and movable endwise to control fluid flow through a first port, a sleeve, and a slider in the cavity structure, and in the path of fluid flow toward the primary piston, the sleeve and slider being coaxially relatively axially movable, and there being a regulator spring acting to urge the sleeve in one axial direction, and fluid flow control slots formed by the sleeve and slider to control flow both to the piston for controllably displacing same, and to the first port. The piston is displaced to close the first port after a required quantity of fluid has passed through the fuse, the slider is hollow to pass flow via the primary slot means from the slider interior to the slider exterior, and via the primary slot means toward the first port.
