Abstract:
1. A device for injecting highly pressurized fuel into a combustion chamber of an internal combustion engine, comprising: an injection valve; a discrete accumulator chamber for the fuel, the discrete accumulator chamber being arranged in a housing being connected to a high-pressure supply line and being assigned to the injection valve; a non-return valve arranged in the housing and acting between the discrete accumulator chamber and the high-pressure supply line; the non-return valve having a valve member interacting with a valve seat and having a throttle passage for the fuel; the non-return valve ensuring rapid flow of fuel into the discrete accumulator chamber and the injection valve and the non-return valve damping the dynamic pressure waves from the injection process of the injection valve to the injection process of a next injection valve to such an extent that all the injection processes take place under practically identical conditions; a filter for the fuel arranged in the housing; and the filter forming a stop for limiting the open movement of the valve member.
