Description
Product Overview
The flow-limiting bolts are assembled in the high-pressure oil path of the VE distribution pump. They control the maximum fuel flow in the oil path through internal precision damping holes and side分流 holes， limiting the peak oil pressure of the system， buffering the impact of fuel supply pulses， and protecting the internal pistons， cam plates， and other precision parts. After long-term high-pressure erosion， the damping holes may become clogged and the threads may be worn， resulting in oil pressure loss， unstable power， and rapid wear of internal pump parts. This product is precisely machined as an integrated unit. It undergoes flow-limiting accuracy detection upon leaving the factory. It can be simply replaced to repair abnormal oil pressure issues. It is suitable for maintenance of light trucks， agricultural machinery， and small construction machinery VE distribution pumps with mechanical type.
Unique Core Features of the Single Product
Double-ended segmented standard threads， universal connection for both oil paths
The bolts are equipped with different-length standard external threads at both ends. One end connects to the internal oil passage of the pump body， and the other end connects to the high-pressure oil path component. The thread pitch is uniformly standard， suitable for the assembly of conventional distribution pump oil paths. The thread engagement is tight without oil leakage.
Integrated hexagonal clamping platform in the middle， no damage to threads during disassembly and assembly
The integrated hexagonal positioning protrusion in the middle of the bolt allows for force application with a wrench when disassembling and assembling during maintenance， completely avoiding the threads at both ends， eliminating thread slippage and tooth wear， and reducing the probability of assembly leakage and rework.
Dual分流 small holes on the side， buffering oil pressure pulse impact
Precision分流 holes on both sides of the bolt column， allowing for a small amount of fuel to be diverted and released for pressure relief. This buffers the peak oil pressure during fuel supply， reduces oil path pulsation vibrations， and reduces the impact and wear on internal pump parts.
Precision damping holes at the bottom， precisely controlling the maximum oil flow in the path
A micro-limiting damping hole is built into the end of the bolt. The hole diameter is uniformly calibrated， constantly limiting the flow of oil in the path， stabilizing the oil pressure of the pump， and preventing rapid aging and damage to the piston and seals due to excessive oil pressure.
Overall galvanized and passivated steel， resistant to diesel corrosion and not prone to rust
The entire high-strength carbon steel is precisely machined as a unit. The surface is treated with galvanization for rust prevention. It is not prone to oxidation and rusting even when immersed in diesel or exposed to high-temperature and low-temperature environments in the engine compartment. The holes will not be clogged due to rust， and the flow-limiting performance remains stable over the long term. Applicable scenarios
Suitable for medium and small-sized VE distribution diesel fuel injection pumps, covering light-duty freight trucks, agricultural tractors, small wheeled loaders, mobile diesel generators, and diesel equipment for field and construction sites with high and low temperatures, multiple dusts, and light loads. It is applicable for the overhaul of fuel supply systems of diesel equipment in these areas.
