2 417 413 056 Injector Pump Overflow Valve for Bosch systems

What does an injector pump overflow valve do?

This injector pump overflow valve serves as a vital pressure regulation component within the fuel injection system. By redirecting excess fuel back to the return line once a specific pressure threshold is reached, it maintains constant internal pump pressure. This stabilization is essential for ensuring consistent fuel delivery to the injectors and maintaining overall engine running stability.

Compatibility and system application

This component is designed to be compatible with Bosch systems used in heavy commercial vehicle engines. It functions effectively in both mechanically and electronically controlled in-line pumps as well as distributor-type pumps, ensuring the recirculated fuel volume remains constant at the required pressure threshold.

Installation and maintenance guidance

For workshop technicians, proper installation is critical to prevent air or contaminants from entering the fuel system. When replacing this part, ensure a clean working environment and verify that the system is thoroughly bled of air after installation to prevent engine faults. Consult your authorized distributor for fitment details.

Troubleshooting and performance

A failure in the overflow valve can lead to disrupted internal pressure balance, irregular fuel flow, and increased consumption. Using high-strength components helps prevent these issues and maintains the integrity of the fuel injection cycle.
