Injection pump non-return valve
In the exhaust union screw there is a non-return valve. The purpose of
this valve is to improve the injection phase by expelling the air in the
fuel and preventing it from being sucked in by the pump during the in-
take phase. This also ensures that the engine stops promptly as soon
as the stopping device is activated by means of the solenoid valve.
