Description
Product Overview
The oil outlet valve component is installed inside the oil outlet valve seat of the mechanical fuel injection pump, serving the functions of one-way sealing, pressure stabilization, and oil cut-off backflow. After long-term high-pressure reciprocating operation, the valve surface may wear and the seal may become loose, which can lead to failure of oil pressure holding, delayed fuel injection, and insufficient combustion. Replacing the brand-new oil outlet valve can restore the rated fuel supply pressure of the fuel pump, optimize the fuel injection effect, and be suitable for the maintenance of light trucks, agricultural machinery, and small construction machinery mechanical fuel injection pumps as a whole.
Unique Core Features of the Single Product
Double-layer stepped integrated structure, with high precision
The upper and lower two-level stepped parts are precisely machined coaxially, and the flatness of the sealing and seating surface of the valve head and valve seat is high. Under high-pressure conditions, the sealing and locking oil effect is stable, and the oil circuit is quickly cut off after shutdown to avoid dripping oil, backfire, and black smoke emission.
Overall quenched hardened alloy steel, wear-resistant and impact-resistant
The entire piece is made of high-hardness alloy steel, and is quenched and hardened as a whole. It can withstand high-pressure reciprocating impact, and is not prone to wear or rust even after long-term exposure to diesel medium. Compared with ordinary parts, it has a longer service life and reduces the frequency of repeated repairs.
Mirror surface grinding of the sealing contact surface, zero pressure leakage and stable pressure holding
The sealing plane is precisely ground to a mirror surface, without processing burrs or fine gaps. When the plunger is pressurized, it quickly seals and locks, ensuring uniform fuel supply pressure for each cylinder, and the engine operation is free from single-cylinder lack of power and shaking problems.
5-piece unified set for complete maintenance of multi-cylinder fuel pumps
One set contains 5 pieces of the same specification oil outlet valves, suitable for simultaneous replacement of multi-cylinder inline fuel pumps. The repair store does not need to purchase separately, and all aging valve components can be replaced at once after disassembly, shortening the equipment downtime.
Uniform processing tolerance standards, no jamming during installation
Strictly unified size tolerance, with high matching degree with the corresponding valve seat and plunger components. Installation is smooth without jamming, no need for manual grinding, and significantly reduces assembly rework rate. Applicable scenarios
Suitable for medium and small-sized four-cylinder and five-cylinder mechanical inline fuel injection pumps, covering light-duty freight trucks, agricultural tractors, small loaders, mobile diesel generator sets. It is applicable to field and construction sites with high and low temperatures, multiple dust particles, and light-load diesel equipment for major oil circuit overhauls.
