Definitions
- the invention relates to a filter device, in particular for gas filtration, the tergeophuse a filter and a filter element having an annular filter medium body, wherein the filter element is received in a receiving space in the filter housing, according to the preamble of claim 1.
- a filter device which is designed as an air filter and having a hollow cylindrical filter element in a filter housing.
- the filter element has two concentrically arranged, perforated cylinder, between which lies a filter medium body which is flowed through radially from outside to inside by the air to be filtered.
- the filter element In a receiving space in the filter housing in which the filter element is accommodated, the filter element is located axially upstream of a dirt discharge, can be removed via the deposited dirt particles from the receiving space in the filter housing.
- the Schmutzaustragsö réelle opens via a funnel in a dirt collecting chamber, which is closed by a valve. As soon as the weight of the accumulated dirt particles is sufficiently large, the valve opens so that the dirt particles can escape into the environment.
- DE 10 2014 01 1 444 A1 shows a filter device with a hollow cylindrical filter element, which has a housing-side calming wall adjacent to an end disk, which surrounds the filter element in an annular manner and extends over an axial partial length of the filter element.
- a bottom-side dirt outlet is introduced in the filter housing.
- the invention is based on the object with simple constructive measures a filter device in such a way that in an effective manner dirt particles are separated from the fluid stream to be filtered.
- the filter device comprises a filter housing and a filter element accommodated in a receiving space of the filter housing with an annular filter medium body on which the filtration of a fluid to be cleaned takes place.
- the filter device is used in particular for gas filtration, for example for filtration of the combustion air to be supplied to an internal combustion engine. In principle, however, an application for liquid fluids is also possible.
- the annular filter medium body of the filter element is flowed through in the radial direction by the reini ing fluid, in particular radially from outside to inside, so that the outside of the filter medium body forms the inflow or raw side and the inner side of the clean side.
- the filter medium body is in particular formed annularly closed and has an internal flow space for receiving the fluid. In a flow through the filter medium body radially from outside to inside, the purified fluid is discharged from the internal flow space in the axial direction.
- the filter housing In the filter housing is a dirt collecting space, which is fluidly connected to the receiving space for receiving the filter element.
- the dirt collecting area is integrated in particular in the filter housing.
- the dirt collecting area absorbs dirt particles which are deposited from the fluid before flowing through the filter medium body.
- the dirt particles can be advantageously derived from the filter housing.
- the dirt collecting area has in the radial direction - with respect to the longitudinal axis of the ringför shaped filter medium body and the filter element - a greater extent than a Anström Scheme within the receiving space, which extends to the upstream side of the filter medium body.
- the radially larger extent of the dirt collecting area provides for a flow tempering, whereby the deposition of dirt particles from the fluid is supported.
- the dirt collecting area is formed annularly encircling. This allows a ringför shaped flow and storage of dirt particles in the dirt collecting area. Irrespective of their circumferential position, particles guided axially in the direction of the dirt collecting area pass into the radially widened section of the dirt collecting area, where they undergo flow settling and attachment to the wall of the dirt collecting area.
- the dirt collecting area adjoins a flow-proof separating element which is located either directly on the filter medium body or at least adjacent to the filter medium body.
- the flow-proof separating element extends over a partial surface of the Filter medium body and prevents or reduces at least one flow of the Filtermedi- um emotionss in this section, whereby a flow calming of the raw fluid is achieved on the upstream side of the filter medium body.
- the separating element is designed, for example, as a calming wall or as a separating film and prevents the fluid to be cleaned at the upstream side from flowing directly through the filter medium body at the position of the separating element.
- the uncleaned raw fluid directed in the upstream side is prevented from flowing directly past the filter medium body at the position of the separating element and is therefore forced to stay in the space on the upstream side of the filter medium body for at least a slightly longer period, with a flow calming accompanied. Following this, the unpurified fluid can flow through the filter medium body.
- the flow calming has the consequence that larger dirt particles, which are carried in the crude fluid, can settle in the space upstream of the upstream side of the filter medium body.
- there is a pre-separation wherein the deposited particles can be advantageously derived via a discharge valve from the filter housing. Due to the pre-separation, the dirt load of the filter medium body is reduced.
- the separating element is located on the filter housing, in which the filter element is received with the filter medium body. If necessary, the separating element can be formed in one piece with the filter housing.
- the separating element is a calming wall, which surrounds the filter medium body in an annular manner and has a spacing from the outside of the filter medium body.

- the separating element is, for example, a separating film which is applied directly to the outside of the filter medium body. In the area of the separating film, no direct radial flow of the filter medium body is possible.
- the separating film rests on the outer edges of the filter folds, wherein along the longitudinal extent of the filter folds a spreading of raw fluid on the inflow side is possible.
- a separating element in the form of a housing-side calming wall and also a further separating element in the form of a filter element-side separating film. These two separating elements are located, in particular, on axially opposite sides of the filter medium body of the filter element.
- the separating element extends from an axial end side of the filter medium body starting in the axial direction and completely in the circumferential direction of the filter medium body.
- the axial extent of the calming element is in any case smaller than the axial total length of the filter medium body, so that a portion of the filter medium body remains free of the separating element.
- the axial extent of a separating element is at most as large as half the total axial length of the filter medium body, for example only a maximum of one third of the total axial length of the filter medium body.
- the separating film is fixedly connected to the filter medium body, for example by gluing or by welding.
- the filter medium body is formed in a fold shape, wherein the longitudinal extent of the filter folds in the axial direction - with respect to the longitudinal axis of the filter element - runs.
- a discharge valve is arranged in or on the dirt collection area, which is adjustable between a closed and an open position, preferably a beak valve, which when applying a negative pressure relative to the environment closes.
- the discharge valve is moved from the closed to the open position, for example by manual operation, by vibration or by a transition of the system into a depressurized state (at standstill).
- the active adjustment of the discharge valve can be done either in a manually controlled manner or by means of an actuator.
- a passive embodiment of the discharge valve is also possible, in particular in such a way that the discharge valve is transferred from the closed to the open position by external action, for example, by the own weight of the collected dirt particles or by the negative pressure on the discharge valve - Closed component, such as a line which is connected to the negative pressure side of a device, for. B. with a radiator fan.
- the dirt collecting area is integrated in the filter housing and forms a section of the filter housing.
- the dirt collecting area is located in the filter housing axially adjacent to the downstream side of the filter element and / or axially spaced from the inlet opening, preferably at the opposite end of the filter housing with respect to the inlet opening, which allows a separation of the dirt particles from the fluid over to carry out the entire inside of the housing wall of the filter housing before the dirt particles reach the dirt collecting area. Due to the centrifugal forces, the dirt particles are carried radially outward, this effect being intensified by an increasing number of roundings of the flow around the filter element.
- the pitch of the guide vanes is thus preferably adjusted so that the flow circulates around the filter element several times after entering through the inlet opening, so that as many particles as possible are carried to the inside of the housing wall before the particles pass over the axial length be carried in the direction of the circulating dirt collecting space.
- the dirt collecting area is preferably formed integrally with the filter housing.
- a wall of the dirt collecting area extends as part of the housing wall further radially outward than a directly axially adjacent region of the housing wall of the filter housing.
- the dirt collecting area is formed in this embodiment as a circumferential, radially outwardly extending extension of the housing wall of the filter housing.

- the dirt collecting area is completely axially outside the filter medium body and is adjacent to an end face of the filter medium body.
- an end plate disposed on the filter medium body forms a separation member that separates the dirt collection area from the filter medium body.
- the dirt collecting area radially adjoins an outlet, which adjoins an end face of the filter medium body and over which the cleaned fluid is discharged axially from the internal flow space in the filter medium body.
- the dirt collecting area arranged axially on the front side of the filter element and of the filter medium body can be combined with a radially widened housing wall. Furthermore, it is possible for the dirt collecting region to extend in the axial direction partly along the filter medium body and partly outside the filter medium body and adjacent to the end face of the filter element.
- the end disk adjacent to which the dirt collecting area is advantageously arranged, is in particular an open end disk which only covers the filter medium body in a flow-tight manner.
- a central recess in the end disk can be used to discharge clean fluid in the internal flow space axially out of the filter medium body.
- the filter medium body has an elongated cross-sectional shape, for example an oval or ovalized cross-sectional shape.
- Non-oval, elongated cross-sectional shapes may also be considered, for example, concavely curved longitudinal sides or straight-sided, flat longitudinal sides or non-oval, curved, convex longitudinal sides.
- the extent of the longitudinal sides is greater than the extension of the narrow sides, it may be appropriate, for example, that the extent of the longitudinal sides is at least twice as large as the extent of the narrow sides.
- the narrow sides are provided for example with a semicircular cross-sectional shape.
- the elongated cross-sectional shape of the filter medium body or of the filter element has the advantage that relatively low installation space can be used for the filter device. In addition, a large inflow area is given on the longitudinal sides of the filter medium body.

- the axial length of the calming wall 27 is, for example, at least one fourth of the axial overall length of the filter element 2.
- the calming wall 27 ensures a flow tempering in this axial section in the receiving space 26 and reduces the flow of the filter medium body 7 in this section.
- the dirt collecting area 14 is fluidly connected to the receiving space 26.
- the calming wall 27 is located axially adjacent to the open end disk 10 and extends in the axial direction, starting from the open end disk 10, over a partial region of the filter medium body 7.
- separating element 27a On the axially opposite side is another separating element 27a in the form of a separating film, which is applied directly to the filter medium body 7.
- the separating film 27a extends in the axial direction from the closed end disk 9 so that the calming wall 27 and the separating film 27a extend axially from the opposite end sides toward the center of the filter medium body 7.
- the axial length of the calming wall 27 and the separating film 27a is at least approximately equal.
- Both separating elements 27 and 27a ensure a flow calming of the raw fluid flowing into the inlet space on the inflow side of the filter medium body, which makes it possible for coarse dirt particles to settle in the annular space 14, which can be discharged via the discharge valve 13.
- the filter medium body 7 can be flown over its entire axial length and its entire upstream side of the raw fluid.
- the calming wall 27 is radially spaced from the inflow side of the filter medium body 7, whereby an annular space is formed between the calming wall 27 and the inflow side of the filter medium body into which the raw fluid can flow.
- the filter medium body 7 is formed in a fold shape, wherein the longitudinal extent of the folds runs parallel to the longitudinal axis 15 of the filter element.
- the raw fluid can flow axially along the folds of the filter media body 7, starting from the subsection of the filter medium body without separating elements flow the portion which is covered by the separation film 27a.
- the filter medium body 7 is also available in the region of the separating film 27a for the filtration of the raw fluid.
