Pipe connector and fuel injection system

摘要

A pipe connector comprising a connector body, a first fitting connectable to a first double wall pipe, the first fitting comprising a first portion connectable to an inner flow space and a second portion connectable to an outer flow space of the first double wall pipe, a second fitting connectable to a second pipe, a third fitting comprising a first portion and a second portion, which first portion is connectable to the third pipe, and a flow channel arranged in the connector body for interconnecting the first portion of the first fitting, the second fitting and the first portion of the third fitting. The pipe connector comprises a leak channel arranged in flow connection with the second portion of the first fitting, a leakage outlet for discharging fluid from the leak channel, a discharge channel extending from the second portion of the third fitting to the leakage outlet and providing a continuous flow connection therebetween, and a closure member having a first position, in which fluid flow from the leak channel to the leakage outlet is prevented, and a second position, in which fluid flow from the leak channel to the leakage outlet is allowed. The closure member is arranged to move from the first position to the second position when fluid pressure in the leak channel rises above a certain limit.
