Product description

The plunger body is usually made of high-strength alloy steel (such as 20CrMnTi), and the surface is quenched to improve wear resistance.
Piston sleeve: It is precisely matched with the plunger body to form a fuel flow channel, and the material is mostly carburizing steel or stainless steel.
Slant/Spiral Groove: Some plungers are designed with slanted or spiral grooves to control fuel metering and injection timing.
Oil return hole: In conjunction with the inclined groove, the plunger moves up and down to achieve the processes of oil inlet, oil pressure, and oil return.
Seals: such as O-rings or sealing rings, to prevent high-pressure fuel leakage.
