Embodiment Construction

[0020] The invention is explained below on the basis of an exemplary embodiment in which the fuel filter system is part of the diesel supply system of a diesel engine, not shown. It will be appreciated that the present invention may also be used in conjunction with other hydrocarbons used as fuels where water separation prior to combustion in the engine is desired or necessary.

[0021] figure 1 A first exemplary embodiment is shown with a filter housing, indicated overall by 1 , which is sealed at the top by a removable cover part 3 . Housing 1 has, in addition to bottom part 5 , an essentially cylindrical configuration with a central vertical axis 7 . A coaxial inner body 9 is inserted into the housing 1 from the upper side of the housing 1 which is open when the cover 3 is removed, and the inner body 9 is relative to the housings by means of seals 11, 13, 15 and 17. Body wall sealed. The inner body 9 with its coaxial inner tube 19 forms an evaporator housing which will b...

Abstract

The invention relates to a fuel filter system, especially for Diesel engines, comprising a filter housing (1) having a fuel inlet (27) and a fuel outlet (29) and a dehydrating filter medium (23) between the inlet and the outlet for the fuel to pass through, the filter housing (1) having a collection chamber (35) for the water trapped by the filter medium from which collection chamber the water can be supplied to a water absorbing and evaporating device (49) via a controlled dispenser (45), the components of the evaporating steam being releasable into the environment through the evaporating steam outlet (51) thereof. The fuel filter system is characterized in that the water absorbing and evaporating device (49) comprises a valve arrangement (59, 61) by means of which the evaporating water outlet (51) can be closed depending on an inadmissible amount of non-evaporated water (55) collected in the evaporating device (49).

Description

technical field [0001] The invention relates to a fuel filter system, in particular for a diesel engine, comprising a filter housing having a fuel inlet and a fuel outlet and a fuel filter between said fuel inlet and fuel outlet A filter medium for separating water flowing through, wherein the filter housing has a sump for the water separated by the filter medium, the water can be supplied from the sump via a controllable discharge device for water containment and evaporation A device, the components of the waste steam formed can be discharged into the surrounding environment through the waste steam outlet of the water containing and evaporating device. Background technique [0002] To protect the injection system, fuel filter systems are usually designed in such a way that not only contaminants such as suspended particles, dust, etc., but also water are separated and removed. Since the separated water may still be contaminated with diesel fuel, direct discharge of the wate...
