Includes bushing and the plunger itself. The plunger is an elongated plunger slightly cylindrical in shape. During operation, the piston moves in the sleeve. In consequence of its reciprocating movement occurs after the injection and suction of fuel. On it there are specials. holes in the sleeve through which fuel is supplied to the discharge. The plunger acts as a valve regulating the quantity of fuel delivered.
From this it follows that it is used for the metering of a precise count of fuel to feed into cylinders of the engine and moreover with its help pump generates the necessary pressure def. moment. In order to ensure quality such tasks during the operation of diesel engines PP must fulfill such requirements as an exception likelihood of fuel leakage. That the provision of this requirement, the gaps between the plunger and the sleeve is made minimum, within 1-3mkm. Such a gap is provided by selecting each plunger is individually to the sleeve and then already fitted to each other.
Also surfaces of the sleeves and plungers harden to a very ultra-high hardness to ensure durability. As a result, the plunger sleeve are a pair of precision, capable of providing a large injection pressure along with the mobility of the plunger inside the sleeve. P>
