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： The invention relates to a filter device with a filter element (1) which can be received in a filter housing that consists of at least two interconnectable housing parts (17, 19). The filter element (1) can be fixed to a housing part (19) in a removable manner by means of a screw connection (32, 33), and an additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). The invention is characterized in that in order to transmit a torque between threaded elements (33) of the screw connection (32, 33) and of the additional screw connection (41), said threaded elements being rotatable relative to each other, a coupling device (43, 46, 61) is added which allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the screw connection (32, 33) reaches the fixed rotational state.

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).

摘要： Disclosed is a filter device having a filter housing (10) that comprises at least two ports (12, 14), such as an inlet for unfiltered matter and an outlet for filtrate, and accommodates a replaceable filter element (16), which is characterized in that by a shut-off device (18) a fluid-conveying connection between the inlet (12) and the outlet (14) that exists in an open position, is blocked in a blocking position, and in that by an actuation device (20) the shut-off device (18) can be brought into these individual positions.
