摘要： Disclosed is a filter apparatus comprising a filter housing having a filter head (3) and a filter bowl (7), which housing accommodates a filter element that separates a non-filtrate side (15) from a filtrate side (17), and comprising a differential pressure measurement device (59), which indicates at least a blockage of the filter element during filtration operation and which has a measurement piston (91) that is guided in a measurement housing (88) in a longitudinally displaceable manner, an end face (90) of which piston being subjected to the instantaneous pressure of the non-filtrate side (15), and the opposite end face of the piston being subjected to the instantaneous pressure of the filtrate side (17), each instantaneous pressure passing into the measurement housing (88) via at least one conduit (57, 61, 65, 89). The invention is characterised in that at least a section (57, 61) of the conduit is arranged in an element cap (43) of the filter element.

摘要： Disclosed is a system for exhaust gas aftertreatment in an internal combustion engine, having at least one filter device (9) comprising a filter element (77) which is accommodated in a filter housing (71) in order to filter a congealable substance, in particular in the form of an aqueous urea solution that can be introduced into the exhaust flow of the internal combustion engine, parts of the filter device (9) interacting with at least one fluid chamber (79) for at least temporarily accommodating the congealable substance inside the filter housing (71), a deformable compensating device (91) being provided as protection against damage to the system caused by volume expansion during freezing of the substance and being arranged inside the filter housing (71), the system being characterised in that the compensating device (91) is an independent component along with the filter housing (71), and in that the compensating device (91) is enclosed by the filter housing (71) at its outer periphery and substantially without spacing in every operating state. A comparable system can be used for pulsation damping and/or volume flow smoothing of fluids to be filtered.

摘要： The invention relates to a filter device. The invention further relates to a filter device comprising a filter element (1), which can be removably accommodated in a sheathing (13) and the filter material (9) of which, through which the fluid to be cleaned can flow, separates a space (3) forming the dirty side during the filtration process from a space forming the clean side, and comprising a bypass valve, the closing body (41) of which, when the pressure difference in the spaces exceeds a limit value range, can be moved counter to the action of a closing spring (21) into an open position that allows the pressure difference to be reduced, is characterized in that the closing body (41) as part of the filter element (1) can be removed from the sheathing (13) while attached to the filter element and can be spatially separated from the closing spring (21) in doing so.

摘要： The invention relates to a modular system for putting together different sized filter elements, especially filter elements having different lengths, more particularly filter devices for hydraulic fluids, comprising a support tube (11, 13) that defines an inner cavity in the corresponding filter element, said tube being surrounded by a filter mat that is substantially cylindrical and that matches the different dimensions and having passages to let the fluid pass through. The filter elements also comprise at least one coupling member (5) enabling connection on the end side of a corresponding support tube to an additional support tube having a location (7) on the end side for interacting with and locking on the coupling member (5). Each coupling member (5) is embodied as an attachment plug element with a crown consisting of interspaced tabs (27) extending in axial direction and hooks (29) for snapping on the location (7) of the attached support tube.

摘要： A filter device, having a filter housing (1) which has a filter head (3), a filter pot (7) and a removable housing cover part (51) and which accommodates a filter element (13) which separates a non-filtrate side (15) from a filtrate side (17), and having a bypass valve device which has a valve closure element (65) which is preloaded by means of a closing spring (69) into a closed position in which it bears against a valve seat part (74) and which, if the filter element (13) is blocked, passes into a position in which it opens up a fluid path from the non-filtrate side (15) to the filtrate side (17), by passing the filter element (13), is distinguished by the fact that the valve closure element (65) and the closing spring (69) are arranged on the cover part (51) and the valve seat part (74) is situated on an element cap (43) of the filter element (13), which element cap has a receiving part (45) which forms an enclosure for that end of the filter material (27) of the filter element (13) which faces toward the cover part (51).
