Definitions
- the invention relates to a valve device according to the preamble of claim 1 and a quantity control valve according to the independent claim.
- Valve devices such as quantity control valves of a fuel system of an internal combustion engine, are known from the market. Often, such valve devices have a valve body which abut against a sealing section against a housing-side sealing seat and thus close the valve means.
- the sealing seat is formed, for example, flat, cylindrical, spherical or conical.
- pressure pulsations can occur in the hydraulic lines connected to the valve device, as a result of which liquid vapor ("vapor bubbles”) can form in the region of the sealing section or the sealing seat.
- vapor bubbles liquid vapor
- Kavitationserosion at surrounding portions of the housing and / or the valve body.
- the valve device according to the invention has the advantage that the resistance in the region of a sealing seat and / or a sealing portion of the valve device is improved against cavitation erosion.
- the flow coefficient or the pressure drop along a flow channel, as well as the valve lift, the valve switching time and the fatigue strength of the valve device remain essentially unchanged.
- the invention is based on the consideration that a high resistance to cavitation erosion in a sealing region formed by a sealing section and a sealing seat on the one hand, and a high flow coefficient of the valve device on the other hand, can be contradictory requirements.
- a high resistance to cavitation erosion in a sealing region formed by a sealing section and a sealing seat on the one hand, and a high flow coefficient of the valve device on the other hand can be contradictory requirements.
- this results in closed valve means a wedge-like cross-section gap between the sealing portion and the sealing seat.
- the bubbles of the fluid formed as a result of cavitation effects-depending on the particular pressure-are decayed last in this gap and thus comparatively quickly, as a result of which erosion of the sealing section and / or of the sealing seat can occur.
- the valve device has a decomposition space in a flow channel immediately upstream of the sealing region when the valve device is closed.
- a boundary wall of the decomposition space is formed by a baffle which adjoins the sealing area, wherein the baffle is tilted at least partially opposite to the sealing region normal with an angle of at most 15 ° in the flow direction to a maximum of 60 ° counter to the flow direction.
- a further boundary wall of the decomposition space runs, for example, approximately parallel to the sealing region, so that an upstream shoulder results upstream of the sealing region.
- An embodiment of the invention provides that the baffle is at least partially tilted against the normal to the sealing region at an angle of at most 5 ° in the flow direction to a maximum of 20 ° opposite to the flow direction, more preferably that the baffle at least partially opposite to the sealing area Normal is tilted at an angle of at most 2 ° in the flow direction to a maximum of 10 ° counter to the flow direction, even more preferred that the baffle is at least partially disposed at right angles with respect to the sealing area.
- the invention provides that the baffle is formed on a housing of the valve device. This is. the decomposition space formed on the housing.
- the decomposition space is inventively formed by means of a step-like recess in the housing and bounded by the impact wall formed on the housing.
- the flow coefficient of the valve device can be improved if a boundary wall of the flow channel upstream of and close to the baffle wall has a rounding or chamfer.
- the flow velocity in the sealing area can be further increased without the cavitation erosion increases.
- a boundary wall of the flow channel immediately upstream of the rounding has an angle with respect to a longitudinal axis of the flow channel of a maximum of +/- 15 ° degrees.
- the cavitation erosion can be further reduced if there is an undercut in a boundary wall of the flow channel upstream of and close to the baffle wall and / or in the baffle wall.
- the valve device When the valve device is closed, the hydraulic end of the upstream fluid region and thus the location of the disintegration of the cavitation bubbles can be kept away from the sealing region.
- valve body is plate-shaped, cylindrical, spherical or conical or it is a conical-cone valve.
- the invention can be used advantageously.
- valve device manufacture of the valve device can be simplified and cheapened if the housing is multi-part in the baffle wall.
- the above-described diverse geometries of the valve device upstream of the sealing region can optionally be produced by separate elements and thus simpler.
- FIG. 1 shows a fuel system 10 of an internal combustion engine in a highly simplified representation.
- fuel is supplied via a suction line 14, by means of a prefeed pump 16, via a low-pressure line 18, and via a valve device 22 which can be actuated by an electromagnet 20 - which in the present case is a quantity control valve 22 - to a high-pressure pump 24 (not further explained here).
- the high pressure pump 24 is connected via a high pressure line 26 to a high pressure accumulator 28.
- Other elements, such as exhaust valves of the high-pressure pump 24 are in the FIG. 1 not drawn.
- the valve device 22 and the quantity control valve 22 may be formed as a unit with the high-pressure pump 24.
- the quantity control valve 22 may be an inlet valve of the high-pressure pump 24.
- the quantity control valve 22 may also have a different actuator than the electromagnet 20, for example a piezoelectric actuator or a hydraulic actuator.
- the prefeed pump 16 conveys fuel from the fuel tank 12 into the low-pressure line 18.
- the quantity control valve 22 determines the quantity of fuel supplied to the delivery chamber of the high-pressure pump 24.
- FIG. 2 shows a first embodiment of the valve device 22 of FIG. 1 in a simplified sectional view.
- the elements of the valve device 22 shown in the drawing are designed substantially rotationally symmetrical about a longitudinal axis 29 and comprise a housing 30 with a sealing seat 32 against which a sealing portion 34 of a valve body 36 can rest when the valve device 22 is closed.
- the valve device 22 is open, that is, the valve body 36 is lifted axially from the sealing seat 32.
- a flow channel 38 is formed through which in the open position shown fluid fluid - in the present case fuel - flows along arrows 40.
- the sealing seat 32 and the sealing portion 34 are flat and parallel to each other and together form a sealing region 42. Upstream of the sealing region 42 is formed by means of a step-like recess in the housing 30, a decomposition space 44, of a from the sealing region 42 and its plane is limited at right angles extending baffle 46.
- Two dashed lines 48 along the flow channel 38 define a cross section of the flow channel 38 with a particularly high flow rate. The distance between the two dashed lines 48 is characterized by a measure 50 downstream of the sealing region 42.
- FIG. 3 shows the valve device 22 of FIG. 2 in closed condition.
- the valve body 36 abuts with the sealing portion 34 on the sealing seat 32, so that a flow of fluid substantially does not take place.
- a region of vapor bubbles 54 is shown, which have formed due to cavitation effects as a result of pressure pulsations.
- the vapor bubbles 54 rest against or are at least closely adjacent to the valve body 36 with a comparatively large area.
- the resulting stress is distributed over a relatively large area of the valve body 36 and the baffle 46, whereby the Kavitationserosion is significantly reduced.
- the valve device 22 in a vicinity of the vapor bubble 54 no narrowing (wedge-like) space sections, which may be particularly prone to cavitation erosion.
- FIG. 4 shows a further embodiment of the valve device 22, wherein the decay space 44 is extended by an undercut 56.
- the imploding vapor bubble (s) 54 can be kept even further away from the sealing region 42, thus further reducing the risk of cavitation erosion on the sealing seat 32 and on the sealing section 34.
- FIG. 5 shows a further embodiment of the valve device 22, wherein the baffle 46 is tilted relative to a sealing region 42 and the plane normal 58 by an angle W1 of 15 ° in the flow direction.
- the angle W1 can also be less than 15 °, whereby the valve device 22 can be even more resistant to cavitation erosion.
- FIG. 6 shows a further embodiment of the valve device 22, wherein the baffle 46 is tilted relative to the sealing region 42 normal 58 by an angle W2 of 15 ° counter to the flow direction. This can further reduce the risk of cavitation erosion.
- the angle W2 can also be up to 60 °. This is in the FIG. 6 but not shown.
- FIG. 7 shows a further embodiment of the valve device 22, wherein a boundary wall of the flow channel 38 upstream of and close to the baffle 46 in place of the edge 52 has a rounding 60 with a radius R1.
- the baffle 46 may also be tilted at a maximum of 15 ° in the flow direction or alternatively at most 60 ° counter to the direction of flow relative to the sealing region 42 normal 58. Both alternatives are in the FIG. 7 indicated by auxiliary lines.
- a boundary wall 61 immediately upstream of the rounding 60 may be tilted with respect to the longitudinal axis 29 by an angle W3 of +/- 15 °.
- FIG. 8 shows another embodiment of the valve device 22, wherein a boundary wall of the flow channel 38 has a chamfer 62 upstream of and close to the baffle 46 instead of the edge 52.
- the baffle 46 can also be tilted relative to the sealing area by an angle W1 or by an angle W2 (compare the FIGS Figures 5 . 6 and 7 ).
- FIG. 9 shows one to the FIG. 8 Comparable embodiment of the valve device 22, wherein the housing 30 is designed in several parts in the region of the baffle 46.
- the chamfer 62 is arranged on a housing element 64.
- FIG. 10 shows the valve device 22 in an embodiment as a conical-cone valve.
- this embodiment is that of FIG. 2 or 3 similar.
- the baffle 46 is oriented approximately at right angles with respect to the sealing portion 34.
- the levels of the sealing seat 32 and the sealing portion 34 and the baffle 46 in comparison to the FIG. 2 or 3, however, by a certain angle - in this case approximately at 45 ° - tilted against the longitudinal axis 29. Accordingly, the angle at the edge 52 is approximately 135 °.
- valve body 36 may be plate-shaped or cone-shaped. Alternatively, however, the valve body 36 may also be cylindrical or spherical, from which further variants of the valve device 22 may result.
