Structure and functions
The nozzle is finished super-precisely to inject the fuel
which is fed from the injection pump under pressure to the
combustion room in good condition. Components as
shown in the right figure are incorporated.
The fuel is fed under pressure from the oil hole of the
nozzle holder main body to the nozzle body. When the
pressure exceeds the specified value, it pushes the spring,
injected from the nozzle, and at the same time lubricates
and cools the nozzle and nozzle body.
The oil leaking at this time is returned to the tank by the
return pipe.
