Abstract
A hydraulic fuse includes cooperating inlet and outlet members within which are positioned a fixed guide having main flow ports and pressure detecting ports, an axially slideable sleeve mounted on the fixed guide and a spring yieldingly urging the slideable sleeve to a position leaving the main flow ports open. Upon the flow rate reaching an excessive level creating an excessive pressure drop, the slideable sleeve is urged forwardly against the biasing action of the spring to a position overlying and closing the main flow ports.
