High-Pressure Fuel Pump for a Fuel Injection System of an Internal Combustion Engine - A simplified explanation of the abstract
This abstract first appeared for US patent application 18044984 titled 'High-Pressure Fuel Pump for a Fuel Injection System of an Internal Combustion Engine
Simplified Explanation
This patent application describes a high-pressure fuel pump for a fuel injection system in an internal combustion engine. The pump includes a housing and a cover that together create a low-pressure chamber.
- The pump housing has a recess where a pressure-limiting valve is located.
- The recess is connected to the low-pressure chamber through a channel.
- The channel has a larger or equal cross-section at the end facing the low-pressure chamber compared to the end facing the recess.
Original Abstract Submitted
A high-pressure fuel pump for a fuel injection system of an internal combustion engine is disclosed. The fuel pump includes a pump housing and a pump cover which is mounted on the pump housing and which, together with the pump housing, delimits a low-pressure chamber. A recess is formed in the pump housing, in which recess a pressure-limiting valve is located. The recess is fluidically connected to the low-pressure chamber via a channel. The channel has the same or a larger cross-section at its end facing the low-pressure chamber than at its end facing the recess.
