Problems solved by technology

However, such sintered bodies can only be produced conditionally with sufficient dimensional accuracy due to the shrinkage of the material accompanying the sintering process
This makes a fluid-tight connection of the sinter body to the filter housing or filter element difficult

Embodiment Construction

[0029] figure 1 A filter system 10 is shown, which comprises a filter housing 12 and a filter element 14 arranged in the filter housing 12 . The filter housing 12 comprises a housing pot 16 which has an annular cover 18 which is crimped to the housing pot 16 and to which an annular sealing element is fastened 20 . The filter housing 12 here has an inlet with a plurality of inlet openings 22 and a centrally arranged outlet 24 for the fluid to be filtered, in particular fuel or oil.

[0030] The filter element 14 is designed here by way of example as a circular filter element and has a filter medium 26 containing glass fibers. In other words, the glass-fibre-containing filter medium 26 can comprise glass fibers or consist entirely of glass fibers. The glass fiber-containing filter medium 26 is arranged annularly relative to the longitudinal axis 28 of the filter element 14 and can be folded, for example, in a star shape. The glass fiber-containing filter medium 26 is arranged...

Abstract

The invention relates to a filter system (10) for filtering a fluid, more particularly fuel or oil, having a filter housing (12), which has an inlet (22) for the fluid to be filtered and an outlet (24) for the filtered fluid, and having a filter element (14) which is arranged in the filter housing (12) and has a fibreglass-containing filter medium (26). A fibreglass barrier arranged fluidically downstream of the fibreglass-containing filter medium (26) is used to retain fibreglass particles (38) contained in the filtered fluid, wherein the fibreglass barrier is designed in the form of a winding body (40) which has a wound-on filter material (48) having an average pore size (52) of less than 20 [mu]m and a maximum winding thickness d of 1.5 mm. The invention further relates to a filter element.

Description

technical field [0001] The invention relates to a filter system and a filter medium for filtering fluids, the filter system and the filter element being provided with a filter medium containing glass fibers. The filter system and the filter element can preferably be used in a motor vehicle, in particular for filtering fuel or oil, or the filter system and the filter element can also be used in a hydraulic system. Background technique [0002] Filter media containing glass fibers are distinguished by their good chemical stability and, in addition, provide a good filtration efficiency with respect to small and very small particulate impurities contained in the fluid to be filtered. For the reasons mentioned above, such glass fiber-containing filter media have proven themselves for the filtration of chemically aggressive fluids, such as fuels for diesel and gasoline motors, for example. In practice, glass fibers or glass fiber particles should be prevented from escaping from t...
