CONNECTION STRUCTURE OF BRANCHED CONNECTOR IN FUEL PRESSURE ACCUMULATOR

摘要

PURPOSE: A connection structure of a branched connector in a fuel pressure accumulator is provided to improve internal pressure fatigue strength by reducing the maximum stress value generated at the internal peripheral edge at the lower end of the branch connector as a branch pipe and a joint-fixing tool. CONSTITUTION: In a connection structure of a branched connector in a fuel pressure accumulator with inserting and joining the branch connector to a through-hole(1-2) formed on an internal peripheral wall(1-1a) of a fuel pressure accumulating container(1), the branched connector is deeply inserted into the through hole until the end of the branch connector is projected from the inner peripheral wall surface of the pressure accumulating container into the inside of the container. In addition, the branched connector includes a branch pipe(2) or a branch joint-fixing tool joining to the through-hole with being inserted into the through-hole.
