Definitions

  • the innovation relates to a valve arrangement according to the preamble of claim 1.
  • Such a valve arrangement is known from DE 296 05 424 U1.
  • the flat spring used is designed as a leaf spring, which runs like a cantilever arm below the valve opening and assumes its open position both due to the restoring force and due to gravity when the engine is at a standstill and is therefore spaced from the valve opening.
  • the oblique arrangement of the valve body to the level of the valve opening can make it difficult to reliably close the valve opening, in particular if tolerances due to the mounting of the leaf spring or due to the production of the leaf spring influence the closing behavior of the valve.
  • the innovation is based on the object of improving a generic valve arrangement to the extent that it enables reliable and uniform closing properties of the valve body with simple and inexpensive means.
  • the innovation proposes to keep the valve body evenly distributed around its circumference instead of a valve body held only on one side, so that it can be moved plane-parallel and not in the form of a pivoting movement.
  • This movement is provided approximately perpendicular to the plane of the valve opening, so that the valve body can be moved between its open position and its closed position, and because of the plane-parallel mobility of the valve opening, it lies evenly when it is moved into its closed position.
  • the valve plate can be manufactured as a flat component.
  • a defined valve gap is established by a corresponding distance, preferably formed as a tool-falling dimension, between the level of the fastening points of the valve plate on the housing on the one hand and the sealing seat of the housing on the other hand. This creates a defined open status of the
  • three or more holding arms provided reliably allow an essentially plane-parallel guidance of the valve body.
  • three holding arms are particularly advantageously provided, since the arrangement of three arms is also possible in the case of limited spatial conditions is easily possible and, on the other hand, the desired tilt resistance of the valve body can be achieved.
  • the spring mobility of the holding arms can be ensured in a simple manner by running them, for example, almost tangentially, slightly spiraling, to the valve body or meandering to the valve body. All holding arms are preferably configured identically, so that uniform guidance of the valve body is ensured. In both of the above cases, a large length of the
  • Holding arms made possible in a small space. This enables a sensitive switching behavior of the valve to be achieved. Despite the small dimensions, the valve can be closed in the reverse direction even with small volume flows. Tolerances, such as those caused by different material thicknesses of the flat spring, only have a very small effect on the mobility of the valve body due to the comparatively large resilient length of the holding arms, so that uniform properties of the valve arrangement are very reliable.
  • the valve body can preferably be part of a valve plate, which also forms the holding arms. In this way, the assembly of several components is not necessary and the valve body can be punched or etched, for example, from a thin sheet metal element together with the holding arms, or it can be produced as an inexpensive plastic injection-molded part.
  • the integration can advantageously go further, so that as few components as possible have to be installed for the assembly of the valve arrangement.
  • the valve plate described above can additionally have fastening means which enable the valve plate to be fastened to the component which has the valve opening. It can advantageously be provided to provide fastening pins on this component, since this component is usually designed as a housing component, and is anyway manufactured three-dimensionally, for example as an injection molded component. Accordingly, the valve disk can be designed as a flat component and openings ⁇ the-with their edges designed as clamping edge, enable attachment to the fixing pins of the housing component.
  • valve plate is held securely on the fastening pins and, on the other hand, due to its deformability, tolerance compensation is possible with slightly different dimensions of the fastening pins or also with slightly different dimensions of the openings or projections in the valve plate. In addition, this ensures simple, inexpensive and safe mounting of the valve plate.
  • the projections or the fastening pins can be dimensioned particularly advantageously in such a way that the valve plate between the fastening points is subjected to tension and thus an undesirable curvature of the valve plate, which would lead to a change in the valve core line, is avoided.
  • the proposed valve arrangement is used in the area of the crankcase ventilation of an internal combustion engine and, for example, with its valve opening creates a connection between a first space in communication with the crankcase and a second space in connection with the intake tract of the internal combustion engine Room.
  • the suggested Use the same valve arrangement as a drain / check valve within an oil mist separator of a crankcase ventilation.
  • the proposed valve arrangement can in particular also be used as a separator bypass valve, which releases a bypass channel for bypassing the oil mist separator at high volume flows, but at the same time enables oil mist to be separated by impact separation or impaction.
  • a separator bypass valve is known from EP 1 285 152 B1 (there FIGS. 5 and 6). It consists of several individual parts, which on the one hand represent a certain cost factor and on the other hand are each subject to a certain manufacturing tolerance.
  • a valve according to the present proposal enables a cost reduction and a higher precision with regard to its opening behavior.
  • the open position in the idle state can be advantageous.
  • FIGS. 5 - 8 further embodiments.
  • 1 shows a valve plate 1, which is approximately triangular in shape, forms a valve body 2 in the middle, in the region of the three corners the valve plate 1 has openings 3, into which projections 4 protrude.
  • Three holding arms 5 extend from the base of the valve plate 1 to the valve body 2. Each holding arm runs approximately tangentially or slightly spiral and extends over an angle of approximately 270 ° along the circumference of the valve body. Because of this great length of the three holding arms 5, the valve body 2 can be moved plane-parallel with little effort, the three holding arms 5 arranged offset around the circumference ensuring the plane parallelism of the valve body 2 during its movements.
  • valve plate 1 is shown above a component 6, which has a valve opening 7 and three fastening pins 8 distributed around the valve opening 7.
  • Fig. 2 shows the mounting situation, while during later operation of the valve assembly the valve plate-1 below the Component 6 is arranged hanging.
  • the free space of the openings 3 remaining between the projections 8 is dimensioned smaller than it corresponds to the diameter of the fastening pins 8, so that the valve plate 1 can be fastened to the fastening pins 8 with essentially elastic deformation of the projections 4.
  • FIG. 3 shows the assembled situation of the valve plate 1, which is fastened to the component 6. From FIG. 3, but in particular from the cross section in FIG. 4 in the region of the valve opening 7, it can be seen that the projections 4 are deformed.
  • the holding arms 5 shows a second exemplary embodiment of a valve plate 1.
  • the length of the holding arms 5 is shorter than the first exemplary embodiment, so that a more rigid spring characteristic is achieved if the valve plate 1 is otherwise out same material and with the same material thickness.
  • the openings 3 are provided with a smooth clamping edge and have no projections which extend into the interior of the opening.
  • a tolerance compensation for this valve plate 1 according to FIG. 5 can be provided in that the corresponding fastening pins, which serve to receive this valve plate 1, have projections on their outer circumference, for example in the form of ribs, which in turn are deformable.
  • each component 6, for example designed as a valve housing can consist of plastic, so that the fastening pins accordingly also consist of plastic, while the valve plate can consist of metal, for example of an approximately 0.1 mm thick sheet steel.
  • Valve plate can also be fastened in that the fastening pins 8 are deformed by melt riveting, tumbling riveting or ultrasonic riveting, so that in these cases the edge of the valve plate running around the opening does not have a non-positive clamping action, but rather a positive fit
  • FIG. 6 shows a third exemplary embodiment similar to that of FIG. 5.
  • the valve body which lies against the valve opening is not formed by the valve plate 1 itself in this exemplary embodiment, but rather carries the valve plate 1 in its Center, which is spring-movable with the aid of the holding arms 5, a valve body 2 made of an additional material, for example made of an elastomer material.
  • the valve body 2 is with the
  • Valve plate 1 connected by, for example, the valve plate 1 is buttoned or molded. Due to the deformability of this elastomeric valve body 2, a reliable sealing seat on the valve opening 7 of the component 6 is ensured.
  • the additional weight of the elastomeric valve body 2 ensures that the central area of the valve plate 1, which carries this valve body 2, is reliably removed from the valve opening 7 when the engine is stopped due to the restoring force of the spring arms and / or due to gravity, and thus the Valve opening 7 releases so that oil present in the valve arrangement can drain off.
  • the aforementioned component 6, which represents a valve housing, can be part of an oil separator, in particular can be designed as an oil collection chamber of such an oil separator, or it can be designed as part of a separator bypass branch.
  • Opening of the valve when the engine is at a standstill is achieved in that, on the one hand, the valve body 2 itself formed by the valve plate 1 is moved downward by the restoring force of the spring arms and / or due to gravity, the hydrostatic pressure of the oil on the valve body 2 additionally pushing the valve body 2 from its closed position into its open position, spaced from the valve opening 7, urges.
  • valve opening 7 has a collar-like bordered mouth 9, which in the rest state shown is at a distance from the valve body 2, so that in the rest state the valve assumes its open position.
  • the valve plate 1 is arranged underneath the mouth 9, so that the valve body 2 supports its opening under the force of gravity fenposition at a distance from the mouth 9 of the valve opening 7 occupies.
  • the mouth 9 lies in a plane which is offset from the plane of the component 6 on which the valve plate 1 rests.
  • the mouth 9 can be provided in a plane which is also offset from the plane of the component 6 on which the valve plate 1 rests, but the collar-like border of the mouth 9 penetrates this plane, so that the valve plate 1 - in particular its holding arms 5 - is deformed and the valve body 2 is biased against the mouth 9 of the valve opening 7.
  • the valve assumes its closed position in the idle state.
  • FIG. 8 shows a stop 10, purely schematically indicated, which limits the deflection of the valve body 2 and which can also be provided in the case of differently configured exemplary embodiments.
  • a stop can reliably prevent damage to the valve arrangement by strong flow forces occurring during operation, strong vibrations or similar forces acting on the valve arrangement.
