Definitions
- the invention relates to a unit for regulating or controlling a fluid pressure, in particular for the pressure control of the internal combustion engine and / or the crankcase of the internal combustion engine of a motor vehicle.
- Pressure control valves are used for example in the vent line between the crankcase and the intake tract of an internal combustion engine. The aim is not to let the pressure or negative pressure in the containers to be vented rise above a predetermined value.
- blow-by gases occur, which arise because combustion gases in the cylinder pass the cylinder piston into the crankcase. These blow-by gases increase the pressure in the crankcase, which can lead to leakage and leakage of oil. In order to avoid an increase in pressure and dissipate the blow-by gases environmentally friendly, they are returned from the crankcase in the air intake tract of the internal combustion engine. On the other hand, the specified negative pressure value should not be significantly undershot, because otherwise would be sucked by leaks accidentally incorrect air in the crankcase.
- switching membrane made of elastomer, often fluorosilicone rubber (FVMQ) used.
- circuit foils are very flexible due to the specific properties of elastomers.
- this switching foil opens or closes an opening in the pressure regulating valve.
- the pressure ratio usually results from the pressure difference between the applied pressure in a first chamber and the prevailing pressure in a second chamber of the pressure regulating valve.
- the pressure in the first chamber may be equal to the atmospheric pressure.
- the switching foil must react to low switching pressures of the order of 1 to 250 mbar. Blow-by gases consist of unburned fuel, engine oil and other pollutants produced during combustion. These gases attack many types of elastomers, which can cause damage to the material properties. The components made of these materials become brittle, porous and cracked.
- the switching foil made of an elastomer is usually designed as a rolling foil to realize a certain stroke of the film.
- the material in the rolling area is additionally mechanically stressed by the rolling movement and simultaneous contact with blow-by gases and can thus be damaged.
- An object of the invention is to provide a unit for switching at low pressure differentials, which achieves long service life when operating on an internal combustion engine with aggressive blow-by gases.
- a further object of the invention is to provide a switching foil for such a unit for switching at low pressure differences, which achieves high lifetimes when operating on an internal combustion engine with aggressive blow-by gases.
- a unit for controlling or controlling a fluid pressure comprising a valve housing comprising a fluid inlet and outlet, and a switching film, wherein the switching film of a fluorine and carbon-containing polymer film is formed.
- the further object is achieved by a switching film for such a unit of a fluorine and carbon-containing polymer film.
- a unit for controlling or controlling a fluid pressure with a valve housing comprising an inlet and an outlet for the fluid, as well as with a switching film for switching at pressure differences of 1 to 250 mbar, preferably from 1 to 100 mbar, for releasing or shutting off a flow of the fluid between the inflow and the outflow, wherein the switching foil is formed from a fluorine and carbon-containing polymer film.
- the unit not only serves to enable or disable a flow, but also regulates the flow of fluid between the inflow and the outflow between the two switching states release or shut-off by a continuous change of the flow cross-section as a function of the pressure difference.
- the fluorine and carbon polymer film is chemically resistant and can switch many cycles of the film valve.
- the long-term stability of the unit is improved.
- the fluorine and carbon containing polymer may be PTFE (polytetrafluoroethylene).
- the switching foil may have a plate-like flat body, with a bending region surrounding a central closure region, wherein the bending region when switching the switching foil by a low-stretch, i. for practical application virtually strain-free, in particular strain-free, bending movement of the closure area relative to a valve seat in the axial direction on the valve seat or moved away from the valve seat.
- the switching film in this embodiment can bend not only in a small area, but over a large area due to the plate-like shape, some areas of the switching foil are little strain. The bending movement is thus carried out over a large area of the switching foil and consequently with little elastic deformation in the form of a change in curvature with a low elongation, for example less than 10%.
- the bending region may extend in a wave-like manner around the closure region in the radial direction.
- the bending region expediently has at least one radially arranged shaft around the closure region, wherein the one or more waves are formed as concave and convexly extending regions of curvature having alternately arranged elevations and depressions of the switching foil.
- an increase on a flat side of the switching foil corresponds to a depression on the other flat side of the switching foil.
- the term wavy not only sinusoidal waves are to be understood but may, for example, also U-shaped or other concave or convex curved contours fall. Even a curved deflection only to one side of an imaginary film plane represents a wave there.
- a conventional switching foil of elastomer of a conventional unit for the pressure control of an internal combustion engine and / or the pressure control of the crankcase of an internal combustion engine is replaced by a film of a fluorine and carbon-containing polymer.
- a fluorine and carbon-containing polymer material such as PTFE can be produced in a sintering process and then mechanically processed.
- Such a film is very stiff in its normal form and not suitable for flexible components.
- PTFE has excellent chemical resistance and can be used in a very wide temperature range, whereby the modulus of elasticity increases very sharply towards low temperatures compared to elastomer materials.
- PTFE is rather unsuitable for use as a film in the temperature range (-40 ° C to + 150 ° C) required for automotive applications on an internal combustion engine.
- This disadvantage is advantageously avoided in the inventive unit by a special geometry and optionally by extremely thin wall thicknesses of the film of fluorine and carbon-containing polymer.
- the immovable sealing area and the clamping area of the material can also be made stronger, and a specially developed geometry of the film without roll area, as he usually in the state of Technology is used, the rigid material can be brought into a form in which it has the necessary flexibility, but still meets the mechanical requirements for cracking, elongation and fatigue strength. Due to the special geometry no rolling movement takes place, but a low-stretch bending movement with a change in radius with the lifting movement of the switching film for a unit can be realized. According to an advantageous embodiment, the switching film has a substantially constant thickness over its entire extent.
- the switching foil is essentially the same thickness, ie that the switching foil in the edge area is at most twice as thick as in the bending area.
- the bending region may be slightly thinner than the edge region of the switching foil.
- the switching foil is at most 0.5 mm thick.
- a spring element may be provided, which is supported on the valve housing, which exerts a force on the closure region of the switching film.
- the spring element exerts the appropriate counterforce on the switching film in order to achieve the control behavior of the unit in the desired pressure range.
- the side facing away from the fluid to be controlled side of the switching film is usually applied to atmospheric pressure.
- the spring element can be supported on the closure area via a plate. As a result, a stable support of the spring element is achieved on the switching film, so that a defined force is ensured in the switching film.
- the switching foil which is designed according to the invention as a thin fluorine and carbon-containing polymer film, thereby protected against possible damage by the spring element.
- the closure region may have a cup-shaped protuberance. Due to the cup-shaped protuberance a stable shape of the closure area is achieved, whereby a reliable seal when placing the Closure area can be ensured on the valve seat.
- the protuberance itself is not influenced in its shape by the bending movement of the switching foil and retains it for the reliable sealing effect.
- the spring element may be arranged around the cup-shaped protuberance. Thus, a uniform force is achieved by the spring element in the switching film, wherein the formed as a protuberance closure region is not affected by the introduction of force in its shape. This is all the more ensured, as the plate of the spring element is placed annularly around the protuberance, so that the plate additionally stabilizes the shape of the protuberance.
- the protuberance as a closure region is arranged in an inner region of the spring element.
- the spring element on its front side, which faces the protuberance be encapsulated.
- a realization of the plate of the spring element in the form of an encapsulation with plastic can very conveniently and conveniently effect a compound of the spring element with the switching film.
- the thin fluorine and carbon-containing polymer film is thus additionally protected against mechanical stress in the region of the spring element.
- a first chamber of the unit can be acted upon by an atmospheric pressure.
- the switching foil should be able to move as freely as possible, which is why a first chamber, which is separated by the switching foil from a second chamber in which the fluid to be controlled is separated, expediently with the surrounding area, ie the atmospheric pressure, communicates.
- the spring element compensates for the atmospheric pressure, so that the control behavior of the switching foil can take place in a low pressure difference range.
- the switching foil can be movable switchless between their maximum positions in the open and closed state. It can be done opening and closing the switching foil, without ever a moving contact plunger acts on both sides of the switching foil and these in the one or other direction moves. Rather, the switching film can be moved back and forth alone by a pressure difference on both sides of the switching film.
- the switching foil can be moved back and forth between its maximum positions in the closed and opened state by means of movable mechanical actuating means engaging on the switching foil, for example switching tappets.
- the closure region of the switching foil can interrupt the flow of the fluid between the inflow and the outflow.
- the switching foil can rest directly on a sealing seat to interrupt the flow.
- the switching foil can be moved between its maximum positions in the opened and closed state by applying atmospheric pressure as the control pressure on one side of the switching foil.
- the switching foil is self-regulating, and the switching foil can be closed indirectly, via a pressure difference between atmospheric pressure in one chamber of the unit and a working pressure of the other chamber of the unit.
- the working pressure can be, for example, a pressure in a crankcase of an internal combustion engine.
- the switching foil can be movable between its maximum positions in the opened and closed state by applying a control pressure unequal to one atmospheric pressure on one side of the switching foil and / or providing a mechanical actuating means for switching the switching foil.
- the switching foil can have a thickness of at most 0.5 mm, preferably of at most 0.3 mm, particularly preferably of at most 0.2 mm, at least in the bending region.
- a thickness of the fluorine-and-carbon-containing polymer film for example PTFE film or PTFE-containing film, makes it possible for the film to bend sufficiently easily at low differential pressures without substantial elongation. drive.
- wavy bending area and small thickness of the film can cooperate to allow low switching pressures.
- the film can ensure the desired switching behavior by closing the valve seat with the closure region of the switching film.
- the switching foil may have a diameter between 40 mm and 100 mm, preferably between 50 mm and 80 mm. Switching films in the specified diameter reach at the film thicknesses specified above enough freedom of bending movement to achieve the desired control behavior in one unit at the desired low pressure differences.
- vent valves for conventional internal combustion engines in the automotive sector can be represented efficiently. It is conceivable that with correspondingly larger diameters, somewhat higher thicknesses of the switching foil in the range of more than 0.5 mm, e.g. at most 1 mm to 0.5 mm, are feasible.

Since the switching film in this embodiment can bend not only in a small area, but over a large area due to the plate-like shape, some areas of the switching film are little strain. The bending movement is thus carried out over a large area of the switching foil and consequently with little curvature.
- the bending region may extend in a wave-like manner around the closure region in the radial direction.
- the bending region expediently has at least one radially arranged shaft around the closure region, wherein the one or more waves are formed as concave and convexly extending regions of curvature with alternately arranged elevations and depressions of the switching foil.
- a bulge on a flat side of the switching foil corresponds to a depression on the other flat side of the switching foil.
- the central closure region can be everted in a pot shape. Due to the cup-shaped protuberance, a stable shape of the closure area is achieved, whereby a reliable seal can be ensured when placing the closure area on the valve seat.
- the protuberance itself is not influenced in its shape by the bending movement of the switching foil and retains it for the reliable sealing effect.
- At least the bending region can have a thickness of at most 0.5 mm, preferably of at most 0.3 mm, particularly preferably of at most 0.2 mm, and the flat body in particular has a diameter which is less than 150 mm between 40 mm and 100 mm, more preferably between 50 mm and 80 mm.
- a small thickness of the fluorine-and-carbon polymer film makes it possible for the film to flex sufficiently easily at low differential pressures without experiencing substantial elongation. It is conceivable that with correspondingly larger diameters, somewhat higher thicknesses of the switching foil in the range of more than 0.5 mm, for example at most 1 mm to 0.5 mm, can be realized.
- the film can ensure the desired switching behavior by closing the valve seat with the closure region of the switching film.
