High-Pressure Fuel Pump - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240344492 titled 'High-Pressure Fuel Pump
Simplified Explanation: The patent application describes a high-pressure fuel pump with a pressure-limiting valve that connects high-pressure and low-pressure regions, allowing fluid flow towards the low-pressure side. The valve is located in a through bore in the pump body, closed on one side by a pressed-in closure. The valve bore has a stepped design with different diameter portions and an annular step. The valve includes a valve seat body pressed into the bore, a valve element pushed by a holding element in the closing direction, and a spiral spring supported on the annular step.
- The high-pressure fuel pump features a pressure-limiting valve that controls fluid flow between high and low-pressure regions.
- The valve is positioned in a through bore in the pump body and closed on one side by a pressed-in closure.
- The bore has a stepped design with varying diameter portions and an annular step for support.
- The valve includes a valve seat body pressed into the bore, a valve element pushed by a holding element, and a spiral spring for support.

Original Abstract Submitted
a high-pressure fuel pump has a pressure-limiting valve, which fluidically connects a high-pressure region to a low-pressure region and opens towards the low-pressure region. the pressure-limiting valve is disposed in a pressure-limiting valve bore, which is designed as a through bore through the pump body, extends from a damping region to a stepped chamber, and is closed on the side facing the damping region by a pressed-in closure. the pressure-limiting valve bore is a stepped bore having a larger diameter first portion, a smaller diameter second portion, and an annular step between the first and second portions the pressure-limiting valve has a valve seat body pressed into the pressure-limiting valve bore, and a valve element, which is pushed in the closing direction by a holding element, which is pushed in the closing direction by a spiral spring, which is supported on the annular step.
