Estimating the term…
The invention relates to a fuel supply system for an internal combustion engine, having a unit such as a pressure regulator, mounted in electrically insulated fashion and including an electrically conductive housing, and the housing is connected via an electrical connection to a defined electrical potential. As a result, static charging of the unit, which could become dangerous, is precluded. The fuel supply system is intended in particular for pumping fuel to an internal combustion engine of a motor vehicle.
A fuel supply system, having a fuel pump that pumps fuel from a fuel reserve via a unit (8, 8′, 80), in which the unit (8, 8′, 80) includes at least one electrically conductive component (10, 11, 12, 82) retained so as to be electrically insulated from an electrical potential of an electrical conductor, and the electrically conductive component (10, 11, 12, 82) is connected via an electrical connection (40, 40′, 42, 42′) to the electrical potential (41) of the electrical conductor (44, 44′, 76, 78).
A fuel supply system, having a fuel pump that pumps fuel from a fuel reserve via a unit (8, 8′, 80), in which the unit (8, 8′, 80) includes at least one electrically conductive component (10, 11, 12, 82) retained so as to be electrically insulated from an electrical potential of an electrical conductor, and the electrically conductive component (10, 11, 12, 82) is connected via an electrical connection (40, 40′, 42, 42′) to the electrical potential (41) of the electrical conductor (44, 44′, 76, 78), characterized in that a clamping spring (74, 74′) is provided, and the clamping spring (74, 74′) has a ring (74a) on which radially-inward pointing tabs (74b) are provided, and the tabs (74b) protrude so far inward that after being slipped onto the component (10, 11, 12, 82), the tabs (74b) are bent over, so that the clamping spring (74, 74′) is interlocked with the component (10, 11, 12, 82).
