Grounding of a filter by means of an electrically conductive conductor trace on the filter element

Abstract

The invention relates to a filter (1) for filtering a liquid (3). The filter (1) comprises a filter element (5) that is designed to clean the liquid (3) of undesired particles. The filter element (5) is arranged between a first end cap (7) and a second end cap (9). The filter element (5), the first end cap (7) and the second end cap (9) are designed to be electrically nonconductive. An electrically conductive conductor trace (11) is arranged on the filter element (5) in order to dissipate electric charge.

Description

Background technique [0001] If the liquid flows through tight gaps or components with small cross-sections, friction between the component and the liquid will result. This can lead, in particular at high flow rates of the liquid, to a charge separation and thus to an electrostatic charging of the flow-through components. [0002] Especially in environments with components that can possibly be ignited, for example in fuel tanks, it is important to avoid electrostatic discharges, also known as “elektro static discharges” (ESD). Furthermore, electrostatic discharges must be avoided in order to avoid undesired effects on surrounding electrical installations. Furthermore, electrostatic discharges should be prevented in order to avoid material abrasion, so-called “pinholes”, by repeated spark discharges at the same point. [0003] In the case of filters, in particular fuel filters, this is achieved, for example, in that the individual components of the filter, such as the filter h...
