Definitions
- Valve device with a valve seated in a valve seat
- the invention relates to a valve device with a valve seated in a valve seat, the valve having a valve axis running longitudinally in two opposite axial directions, a valve housing running coaxially to the valve axis and at least one stop seated on the valve housing, and the valve seat having an internally cylindrical shape Valve seat is provided in which the valve sits with an outer cylindrical first housing portion of the valve housing.
- valves of the type used in the device of the genus are used, for example, to regulate pressure in converter transmissions.
- An example of an application is disclosed in DE 102007035 706 A1.
- This valve is designed as a check valve, sits in a transmission input shaft and is housed in a hydraulic circuit of an automatic transmission. It has a valve housing made of sheet metal and a seal.
- the seal is an O-ring which sits in a circumferential groove at the inlet opening of the valve housing.
- the sheet metal of the valve housing is shaped in the form of a channel for receiving the O-ring.
- valve housing of the valve is a formed part made of sheet metal.
- the piston of this valve is a ball which is axially pretensioned by means of a compression spring against a piston sealing seat at the inlet opening of the valve housing.
- the valve housing has a 2-stage design, i. That is, it has a first housing section and a second housing section. The diameter of the housing sections differ. The outside diameter of the first housing section is larger than the outside diameter of the second housing section.
- a support element, on which the compression spring is axially supported, is introduced into the valve at the rear.
- a valve device of the type with an electromagnetic valve is described in DE 10 2007040691 A1.
- the valve device has an upper housing part with a magnetic core and a valve with a valve housing, which are arranged axially next to one another and coaxially to one another.
- a piston rod of the piston of the valve dips into the upper part of the housing and interacts with a magnet armature.
- the housing of the The valve sits in a valve receptacle of a receptacle body is fixed to the receptacle body with a caulking of a flange.
- the flange is designed as a stop against the receiving body in one piece on the valve housing and protrudes in the radial direction beyond the valve housing.
- An O-ring is clamped between the flange and the receiving body.
- valve is described in DE 102006007583.
- An outer part of the valve housing with an inlet opening formed at the end is supported in an axial direction in a valve seat formed as a blind hole.
- An inner part of the valve housing serves as a guide for a closing ball of the valve and as a support for the piston spring of the closing ball in an opposite axial direction.
- the valve is supported axially in the opposite axial direction via a sleeve of the inner part on a locking ring which is seated in the bore of the valve receptacle.
- the sleeve engages over the outer part of the valve housing on a side facing away from the inlet opening.
- a seal designed as an O-ring is clamped between the outer part and the valve receptacle and held in position by means of the sleeve.
- valves of the known prior art When installing the valve in the housing, the valves of the known prior art initially have the option of inserting the valve into the valve seat of the housing either with one side or the other side first, regardless of the installation direction required for the function of the valve. It can therefore lead to errors when assembling the valve in the housing in such a way that it is installed the wrong way round. If this error remains undetected during further assembly of the gear unit, it will not work when it is commissioned. Elaborate troubleshooting or repairs are necessary or the gearbox is scrap.
- valve is described, for example, in DE 102007 029466 A1.
- the valve has an outer diameter throughout, subject to two beads. In one of the bead there is a seal in the form of an O-ring. Since both ends of the valve have the same diameter, it could also be inserted the wrong way round into a valve seat.
- the device according to the invention is formed from a housing and a valve seated in a valve seat of the housing and from at least one axial stop.
- the radially and axially rigid stop sits on the valve housing of the valve.
- the stop is designed so that the radially extending largest stop dimension is larger than the inner diameter of the valve seat in a housing.
- the stop dimension is defined by a radial distance between the valve axis and a region or a body edge of the stop that is most distant radially from the valve axis.
- the housing is, for example, a housing section of a housing of a vehicle transmission, a transmission shaft, a hub or any other component in which the valve seat can be formed.
- the valve seat is defined as a receptacle, preferably as a bore, into which the valve is inserted, held and / or pressed.
- the invention provides that the stop sits at an inlet opening of the valve on the valve housing, with a first flow channel of the valve device leading to the inlet opening and with the inlet opening being formed at a first end of the valve, which is axially of a second end having the first housing section At the end of the valve is removed, at least one flow opening which is oriented radially, ie transversely to the valve axis, is formed on a second housing section of the valve housing axially adjoining the first housing section.
- the advantage of the invention is that the valve housing, together with the stop, prevents the incorrect assembly described above.
- the stop is preferably designed as a seal, a sealing lip of a seal or as a reinforcement of a seal.
- the stop acts as an axial stop that prevents the valve from going upside down, i.e. H. can be introduced into the valve seat with its inlet opening and / or with the seal first.
- the outside diameter of the stop, or the outside diameter of the seal, and / or the outside diameter of the reinforcement of the seal is / are larger than the inside diameter of the valve seat in the housing.
- the valve usually has to be completely accommodated in the valve seat. If the valve is inserted upside down into the receptacle of the housing with the inlet opening first, it can only be moved axially until the stop axially strikes the contour delimiting the opening of the valve seat. In this case, the back of the valve then obviously projects axially beyond the receptacle in such a way that this is recognized as a fault. The error is recognized in good time before the further assembly of the transmission and can be corrected.
- the inner diameter of the inner cylindrical contour of the insertion opening corresponds to the outer diameter of the first annular gap.
- the outer diameter of the first annular gap is thus just as large as and / or smaller than the outer diameter of a second annular gap.
- the second annular gap adjoins the first annular gap axially. If the second annular gap is not externally cylindrical, the second annular gap must, however, offer so much free space radially that it is described radially on the outside by a minimum radius of an imaginary hollow cylinder.
- the minimum radius must be the same size, but preferably greater than the inside diameter of the valve seat, so that the first housing section of the valve housing can be inserted axially unhindered through the first feed-through cross section into the valve seat.
- a flow opening designed as a transverse opening is directly opposite the open cross section of a flow channel running in the housing.
- a housing section Only in this way can the fluid flow unhindered from the valve into the flow channel or, conversely, from the flow channel through the flow opening into the interior of the valve.
- the housing is preferably a housing of a vehicle transmission or a vehicle clutch.
- Housing is to be understood as meaning all components of a housing, but also other components, such as the housing of pumps, gear wheels and shafts.
- the housing is provided with an internally cylindrical valve seat, which is, for example, a receiving bore and forms a seat for the valve housing. The valve sits with the valve housing with tight radial play or by means of a press fit in the valve seat and is thus guided or held radially in the housing.
- the valve is preferably designed to be essentially rotationally symmetrical. This applies to both the valve housing and the piston.
- the axis of symmetry is the valve axis, which is defined as being axially aligned in the longitudinal direction for a better understanding of the directions “axial” and “radial”.
- axial is consequently defined as being aligned with the valve axis and radial is consequently defined as being oriented transversely to the longitudinal direction or valve axis.
- the valve housing can be made in one piece or composed of several parts.
- the valve housing is preferably made of sheet metal and is produced by cold forming.
- the valve housing is divided into at least two housing sections. With the first housing section, the valve sits in the valve seat.
- the second housing section has the at least one flow opening and is surrounded by the second annular gap.
- the second annular gap is to be understood as a radial free space between the valve housing and an inner contour of the valve receptacle of the housing, its inner contour is predetermined by the outer contour of the second housing section of the valve housing.
- the outer contour of the second annular gap can be designed spatially as desired, for example with axial and radial undercuts and radial depressions and projections. However, the radial depressions and projections do not protrude into the second annular gap.
- the valve housing has at least one flow opening.
- This flow opening can also be referred to as a transverse opening because it is predominantly oriented transversely to the valve axis - which also does not rule out an oblique orientation with respect to the valve axis that deviates from a right angle.
- the valve housing has at least one flow opening but also alternatively several flow openings which are adjacent to one another on the circumference or also axially to one another. If several flow openings are formed, these can also be axially offset from one another.
- the second annular gap is delimited radially in one direction by the second housing section and radially in the other direction by wall sections of the housing on the valve seat, the wall sections of the housing also being interrupted by openings in flow channels for the fluid.
- the fluid can be exchanged either via the second annular gap and the inside of the valve and through the flow opening (s) in both directions. Alternatively, the fluid leaves the valve via the flow opening (s) and flows from there into the second annular gap and possibly further via flow channels into other components.
- the outer contour of the second annular gap must at least fit an imaginary hollow cylinder aligned concentrically to the valve axis in such a way that its radius is greater than the radius of the valve seat. This is the only way the valve can be guided with the back first, i.e. with the first housing section first, first through the insertion opening and then through the valve receptacle to the valve seat and finally inserted or pressed into the valve seat with an accurate fit.
- the free cross section of the second annular gap on the valve seat can have radial dimensions in the area of the second annular gap which are larger than the radius of the imaginary hollow cylinder.
- the free cross-section at this point must, however, be at least large enough that it thereby depicts a narrowest free cross-section between opposing wall sections of the housing, which is defined by the radius of the Hollow cylinder is defined.
- the hollow cylinder thus defines a free cross-section that extends radially between the valve housing and the housing, which is necessary both for the assembly of the valve and for the formation of the annular gap and which, however, also due to the most varied designs of the housing, for example
- the position and geometry of flow channels in the housing can be larger than the outer radius of the hollow cylinder. It is therefore not excluded that there is a radial distance between the outer contour of the second housing section and the inner contour of the housing that is greater than the radius of the hollow cylinder in some places.
- the seal can be designed in any way and, in its simplest form, can be designed as an O-ring.
- the seal can also have one or more sealing lips.
- the advantage is that the seals can be designed to be adapted to different pressure media or fluids or different pressures or temperatures without much effort and without changing the surrounding construction or without changing the valve with regard to their geometric design and material.
- Another embodiment of the invention provides that the seal has a reinforcement. Reinforcement can advantageously serve as the basis for applying several sealing lips of the same or different design and / or reinforce the sealing lip (s).
- a secure fit of the seal in the housing or preferably on the valve housing can be ensured by means of a reinforcement.
- the invention provides a two-fold or three-fold stepped valve housing as refinements.
- the valve housing is stepped in two ways if the first housing section and the second housing section have different outer diameters.
- the valve housing is stepped three times if it has a third housing section and this third housing section has a different outer diameter than the housing section of the valve housing adjacent to the third housing section.
- a gradation can be used to adapt to changed installation conditions simply by changing the valve housing.
- the working cross-sections of the valve such as the cross-section of the inlet opening, the cross-section or cross-sections of piston sealing seats for one or more pistons can be adapted to the desired operating conditions.
- Variable operating conditions are, for example, pressure and flow rate. In the same way, it can be adapted as required to the functional or manufacturing-related installation conditions of the transmission.
- one embodiment of the invention provides at least one piston guided axially movably along the valve axis in the valve housing, by means of which both the at least first opening and the second opening (s) can be closed optionally or at the same time.
- Valve receptacles for valves are usually relatively complex to manufacture by machining. It is therefore advantageous if these have cross-sections that are as uniform as possible. Housings are usually designed with a large volume and are cast, for example.
- the reinforcement has an outside diameter which is smaller than or equal to the inside diameter of the valve seat.
- the reinforcement and thus the entrance opening can have a diameter can be kept relatively small because the diameter of the seal can be kept radially small.
- the axial stop against incorrect assembly is preferably ensured on the one hand by the reinforcement and on the other hand by the portion of the sealing lip (s) protruding radially beyond the reinforcement, which despite its elasticity is sufficiently rigid due to the reinforcement at the zone defined by the stop dimension are held to withstand incorrect assembly of the valve. Consequently, one embodiment of the invention provides that the sealing lip has an outer diameter which is greater than the inner diameter of the valve receptacle.
- the reinforcement is preferably designed in the shape of an annular disk, but can also consist of one or more radial segments.

- the second housing section 12 is surrounded by a second annular gap 10, which is formed radially between the valve housing 4 and an inner contour of the valve receptacle 30.
- the third housing section 13 of the valve housing 4 is surrounded by the first annular gap 14, which is formed radially between an inner cylindrical surface of the insertion opening 38 and the valve housing 4.
- the seal 11 is seated on the third housing section 13 and closes the first annular gap 14 in such a way that a passage for fluid between a first flow channel 26 and the second annular gap 10 is sealed.
- the seal 11 consists of a reinforcement 18 and at least one sealing lip 19.
- the reinforcement 18 is an angle ring which sits with an axially aligned leg 29 on the third housing section 13 and which holds the sealing lip 19 on a radially aligned

- a ventilation opening 28 is formed on the rear of the piston 16 in the support element 21.
- the valve 2 In the operating state of the valve 2 shown in FIG. 1, the valve 2 is closed. In the illustration, the piston 16 rests in a sealing manner on a piston sealing seat 22 (FIG. 1) which is formed at the transition between the second housing section 12 and the third housing section 13 of the valve housing.
- valve seat 30 is a cavity in the housing of a vehicle transmission or other component of a vehicle transmission into which the valve 2 is inserted.
- FIG. 1 a - The housing 3 is provided with the valve receptacle 30 and has a valve seat 6, a flow channel 26 as well as at least one flow channel 27 and an insertion opening 38.
- the valve seat 30 is designed to be stepped at least three times in terms of the diameter of its openings.
- the first opening stage 32 is formed by valve seat 6.
- the second opening step 33 is formed by an inner cylindrical section of the valve receptacle 30 which surrounds at least the second housing section 12 of the valve housing 4.
- the third opening stage 34 describes the insertion opening 38.
- the inner cylindrical valve seat 6 is described by a valve seat inner radius VR1.
- the inner diameter of the valve seat 6 is accordingly that of the first opening step 32 of the valve receptacle 30 and corresponds to the nominal dimension of the outer radius GH1 of the first housing section 7 of the valve housing 4.
- the second opening step 33 has at least one radial free cross section, the inner diameter of which is described by the hollow cylinder radius HR1 of an imaginary hollow cylinder 17.
- the imaginary hollow cylinder is, as can be seen from the transition to a flow channel 27, on one side with a dashed line and on the right-hand side of the picture with an intensely drawn / emphasized body edge and describes the outer contour of the second annular gap 10, which is at least given. This means that the second annular gap 10 is described on the outside at least by the hollow cylinder radius HR1.
- the inside of the second annular gap 10 has an inside diameter which is twice the outside radius GH2 of the second housing section 12 of the valve housing 4.
- the inner radius IK1 of the inner cylindrical inner contour of the insertion opening 38 in this case also corresponds to a hollow cylinder radius HR1 of an imaginary hollow cylinder 17 and can, however, also differ from this in other installation situations, not shown.
- the inside diameter of the first Annular gap 14 corresponds to twice the outer radius GH3 of the third housing section 13.
- the elastic sealing lip 19 has an outer radius AD, which is continuously elastically reducible to the outer radius ADUE and in the case of the example shown in Figure 2 is oversized compared to the inner radius IK1 of the insertion opening 38 - that is, when not installed State of the valve is greater than the inner radius IK1. This is indicated in the drawing in the illustration according to FIG. 2 by the dashed lines of the sealing lip 19 extending beyond the drawn body edges of the inner contour in the picture on the right. In the installed state of the valve 2, the radius AD or ADUE is reduced to the inner radius IK1 of the body edge of the inner cylindrical inner contour of the insertion opening 38.
- the sealing lip 19 is elastically constricted or folded over to an outer diameter predetermined by the inner radius IK1.
- the outer radius AD corresponds to the nominal dimension of the inner radius IK1 even when the valve 2 is not installed.
- the inner radius ORI of the insertion opening 38 can, but does not have to be, the same as the inner radius IK1 of the inner contour of the insertion opening 38.
- the inner radius IK1 of the inner contour determines the sealing contact between the sealing lip 19 and the housing 3.
- the inner radius ORI describes the narrowest or widest opening cross section of the insertion opening 38, which can be greater than or equal to the dimensions of the sealing surface on the housing 3.
- Figure 2 - ORi must, however, be larger than the stop dimension AR.
- the stop dimension AR must be larger than the radius VR1 of the valve seat 6.
- the radial dimension AR of the stop 37 is a radius in this case, since both the seal 11 and the reinforcement 18 are rotationally symmetrical components.
- the radius AR is larger than the radius AM of the reinforcement but also smaller than the outer radius AD / ADUE of the sealing lip 19 both in the non-installed and in the installed state and equal to or larger than the inner radius of the valve seat 6, which corresponds to the outer radius GH1 of the first housing section 7 of the valve housing 4 corresponds.
- the outer radius AD of the sealing lip 19 when the valve 2 is not installed can be greater than or equal to the outside diameter ADUE of the sealing lip when the valve 2 is installed.
- the radial stop dimension AR of the stop 37 can be greater than or equal to the radial dimension AM of the reinforcement 18 and must be greater than the inner radius of the inner cylindrical wall of the valve seat 6, the nominal dimension of the inner radius VR1 of the valve seat 6 being the nominal dimension of the outer radius GH1 of the first housing section 7 of the valve housing 4 is equivalent to.
- AR> GH1 VR1 and AD>ADUE>AR>AM;
- FIG. 2 - A valve 2 is inadvertently inserted with the inlet opening 9 and thus also with the seal 11 first into the valve receptacle 30 until the seal 11 is axially in contact with the first opening stage, i.e. the edge of the valve seat 6.
- the first opening stage i.e. the edge of the valve seat 6.
- at least the radial stop dimension AR of the stop 37 or even the outer radius AD of the sealing lip 19 are smaller than the opening inner radius ORI of the insertion opening 38 or the inner radius IK1 of the inner cylindrical inner contour of the insertion opening 38 and also smaller than that of the hollow cylinder Radius HR1 of the imaginary hollow cylinder 17.
- the stop 37 is formed in this case by a radial area of the seal 11 reinforced and supported by the reinforcement 18 with a radius which is designated as the radial stop dimension AR of the stop 37.
- the sealing lip 19 or seal 11 is at least as rigid as the stop 37 that, when the valve 2 is further inserted into the valve seat, it opposes an axially directed resistance force that allows the seal 11 to be easily inserted into the valve seat 6 prevented. In this position, the rear end of the valve 2 or of the first housing section 7 protrudes beyond the edge of the insertion opening 38, so that the incorrect installation position of the valve 2 can also be clearly perceived visually.
- the radial stop dimension AR of the stop 37 can also be just as large or smaller than the outer radius AM of the reinforcement 18. In this case, the outer radius of the reinforcement 17 would be larger than the valve seat inner radius of the valve seat 6. In other cases, not shown, the stop radius AR can also be equal to the outer radius AD of the sealing lip. If the valve 2 or the valve housing 4 has a stepped design, as shown, the radial stop dimension AR must be less than or equal to the inner radius IK1 of the inner cylindrical inner contour of the insertion opening 38.
- the inner radius IK1 of the inner cylindrical inner contour of the insertion opening 38 must be larger than the outer radius GH1 of the first housing section 7 of the valve housing 4 for such a stepped valve 2.
- the opening inner radius ORI of the insertion opening 38 must therefore be sufficiently large (the Opening inner radius ORI is greater than that of the outer radius GH1 of the first housing section 7) in order to be able to introduce the valve 2 with the first housing section 7 first into the valve receptacle 30 and so that the first housing section 7, as shown, can be inserted as intended in the Valve seat 6 comes to sit.
