摘要:
The invention relates to a liquid filter having a drain valve for draining liquid out of a liquid collection chamber, wherein a valve body of the drain valve is adjustable between a closed and an open position and opens or closes a discharge channel for the liquid and a ventilation channel. The discharge and ventilation channels are designed as separate channels, wherein, during the opening movement of the valve body, the discharge channel is opened first and then the ventilation channel is opened.

The invention describes a fluid system (10), in particular filter system, for fluid, in particular fuel, oil, water or urea solution, in particular of an internal combustion engine, in particular of a motor vehicle, having at least one heating device (26) for fluid, and a heating device (26). At least one heating chamber (14) has at least one inlet (18) and at least one outlet for the fluid. In the at least one heating chamber (14), at least one electrically operated heating element (32) is arranged between two holding bodies (28, 30) so as to be in electrical and thermal contact with at least one contact section (40, 2) of at least one of the holding bodies (28, 30). The fluid can flow through at least one inner volume region (58) between the two holding bodies (28, 30) and at least one outer volume region (62, 64) on an outer side, facing away from the at least one inner volume region (58), of at least one of the holding bodies (28, 30). In at least one enlarged section of the at least one inner volume region (58), a spacing between the two holding bodies (28, 30) is larger than a spacing between the holding bodies (28, 30) in a region of the at least one contact section (40, 52), at least on that circumferential side thereof which faces toward the at least one enlarged section.

The invention relates to a filter element (14) having a filter medium (22). The filter element (14) can be connected to a filter housing of a filter via at least one bayonet-type protrusion (52) of the filter element (14). The bayonet-type protrusion (52) projects radially, i.e. perpendicular to the central longitudinal axis of the filter element (14), beyond the filter medium (22). In addition, the free end (94) of the bayonet-type protrusion (52) points in the direction of the central filter element longitudinal axis (60). The formation of the bayonet-type protrusion (52) according to the invention generates a large free installation space in the region of the bayonet-type protrusion (52), and prevents injuries given that the free end of the bayonet-type protrusion (52) projects radially inwards.

The invention relates to an at least single-stage water-separating filter element (14) for a fuel filter (10). In the direction of the filter element longitudinal axis, on one end, the filter element (14) has a bayonet-type protrusion for securing the filter element (14) in a filter element housing (12) of the fuel filter (10). On the other end, the filter element (14) has an internal sealing element. The internal sealing element permits a separation of the dirty side and the water collection chamber (34) of the fuel filter (10). The filter element housing (12) has a filter element body (16) and a cover (18), the connection of which two components is sealed preferably via an external sealing element. The external sealing element and the internal sealing element are preferably arranged in such a way that, when separating the cover (18) from the filter element body (16), first the seal of the internal sealing element is released, and then the seal of the external sealing element.
摘要:
Ein Flüssigkeitsfilter weist ein Ablassventil zum Ablassen von Flüssigkeit aus einem Flüssigkeitssammelraum auf, wobei ein Ventilkörper des Ablassventils zwischen einer Schließ- und einer Öffnungsposition verstellbar ist und sowohl einen Ableitungskanal für die Flüssigkeit als auch einen Belüftungskanal öffnet bzw. schließt. Ableitungs- und Belüftungskanal sind als getrennte Kanäle ausgebildet, wobei während der Öffnungsbewegung des Ventilkörpers zunächst der Ableitungskanal und anschließend der Belüftungskanal geöffnet wird.
