Definitions

  • the invention relates to an air filter for an internal combustion engine according to the features of the preamble of claim 1.
  • This air filter for an internal combustion engine is known.
  • This air filter consists of a zigzag-folded filter medium, which is supplied with cold, unpurified air, cleans this air and the internal combustion engine feeds. If the cold air at low temperatures and heavy snowdrifts also contains snow, which is sucked in the intake tract of the engine, the snow will accumulate on the filter and can clog this filter.
  • an air filter housing for an internal combustion engine having a first air inlet opening and a second air inlet opening.
  • sliding valves are provided, which are opened at a negative pressure exceeding a certain value, and allow additional air to flow on the filter, so that an engine operation is still possible, even if snow certain parts of the air filter clogged.
  • the slide valves are provided with springs and can move along a guide.
  • the invention has for its object to provide an air filter for an internal combustion engine with a first and a second air inlet opening, wherein the known prior art is improved and a simple and economical solution can be found.
  • the essential advantage of the invention lies in the fact that the second air inlet opening is equipped with an umbrella valve which closes or opens the air inlet opening, wherein the umbrella valve is supported on a sealing edge and consists of an elastomer material.
  • umbrella valves are easy to manufacture and require no additional spring-effective elements, since the structure of a shield valve is designed such that the shape of the screen has a spring-effective function.
  • this is provided with a screen stick or a screen support, which also represents the attachment element for the umbrella valve and is clipped into the wall of a housing of the air filter.
  • a screen stick or a screen support which also represents the attachment element for the umbrella valve and is clipped into the wall of a housing of the air filter.
  • the shield valve is provided with a frame, wherein the frame surrounds an air space between the inlet, which can be opened and closed by the umbrella valve, and an outer contour of the air filter element. If the air filter itself is exposed to snow, this frame keeps the snow away from the room that can be switched on and off by the umbrella valve. Thus, this space can be used for supplying snow-free air.
  • At least one further screen valve is arranged within the frame. It is expedient to dimension the passage area for the air through the umbrella valves essentially so that this area corresponds to the suction area of the intake pipe, so that the internal combustion engine can be supplied with the sufficient amount of intake air. So that no snow-laden air enters via the umbrella valves, it is expedient to arrange the second air inlet opening in an area which is close to a warm component during operation of the internal combustion engine, for example in the region of an exhaust manifold or an exhaust part of the internal combustion engine.
  • a further embodiment of the invention provides, the frame, which is provided from the second air inlet opening to the filter element, so to make it 10 to 30% of the outer surface of the filter element includes, on the one hand, the cleaning of the air with high efficiency is possible, on the other hand, a rapid defrosting of snow in other areas of the filter element can take place.
  • an opening to the outside for discharging liquid, in particular water, is provided within the frame on the housing.
  • a second air inlet opening is located in the geodetically lower region of an air filter housing, in which water can also accumulate. This water is discharged via a small water outlet to the outside.
  • the filter element for cleaning air from a round filter element which has a zigzag folded filter material and is constructed concentrically and advantageously has on its surface a Vorvlies for coarse separation of particles.
  • FIG. 1 shown in sectional view air filter consists of a housing 10, a lid 11 disposed on the housing and a arranged on the housing 10 clean air tube 12 and a in FIG. 2 Rohluftansaugrohr 13.
  • a round filter element 14 which consists of a zigzag folded filter medium 15.
  • This filter medium 15 is arranged on a support tube 16.
  • the support tube seals the round filter element 14 via an additional seal 17 on an inwardly guided nozzle 18 of the clean air tube 12.
  • the round filter element is provided with a closed end disk 19 which has a fixing element 20 in the center, this fixing element 20 resting on the housing structure of the housing 10 and thus positioning the round filter element 14 in the housing.
  • the cover 11 can be pivoted upwards and releases the interior of the filter housing so that the round filter element 14 can be exchanged.
  • the round filter element is on its outer periphery with a Vorvlies 21 for deposition provided by coarse particles. This pre-fleece extends over the entire surface of the round filter element 14.
  • the housing has a frame 22, which - as in FIG. 1 to see - from two frame parts 23, 24 and - as in FIG. 2 to see - consists of the frame parts 25, 26.
  • the frame forms a chamber 38 between the housing bottom and the round filter element 14, that is, the frame extends to its Vorvlies.
  • two umbrella valves 27, 28 are arranged, ie these are, as described below, clipped to the housing or the housing structure.
  • FIG. 1 the surface of the round filter element 14 be free, so that open due to an increased negative pressure within the round filter element 14, the umbrella valves 27, 28 and air can flow from the area below the housing 10 to the round filter element 14, thereby the internal combustion engine is supplied with air.
  • the air leads to a heating of the round filter element 14, so that also the deposited snow will defrost, so that the entire surface of the round filter element 14 can be acted upon with intake air.
  • FIG. 3 shows an umbrella valve viewed from the bottom.
  • the umbrella valve 27 rests on a circumferential web 30 of the housing 10.
  • the housing itself has to support the umbrella valve four webs 31, 32, 33, 34, which are connected in the middle with an eyelet 35. Within this eyelet of the mounting pole 36 of the umbrella valve 27 is engaged.
  • FIG. 4 shows the umbrella valve 27 in a perspective view.
  • the attachment via the attachment floor 36 is effected by a groove 37 which receives the eyelet 35.
  • the umbrella valve may consist of a fluorosilicone. It can of course also consist of an elastomer material. Depending on the opening pressure, the umbrella valve must be designed constructively. The internal elasticity of the umbrella valve ensures a reliable operation of the same.
