Description

[0001] The invention relates to a sanitary insertion unit which with a functional unit that provides a flow opening, which has an adjustment element, said adjustment element is disposed axially in a displaceable or adjustable manner into the opening. flow and out of the flow opening, wherein the adjusting element is in drive connection with a drive element that is disposed on the flow side downstream of the flow opening, and operable from the outside.

[0002] From document EP 2 536 886 B1, a sanitary insertion unit of the mentioned type is already known, which can be used in the water outlet of a sanitary flush valve. In order to be able to change the flow cross-section of the insertion unit and/or the volumetric flow of the circulating water, the known insertion unit has a functional unit that provides a flow passage opening, in which an adjusting element is arranged axially adjustable. in the flow passage opening and outside the flow passage opening. By axial adjustment of the operable adjusting element on a flow side downstream of the flow passage opening the useful flow passage cross-section of the flow passage opening can be changed. In an embodiment of document EP 2 536 886 B1 shown in Figures 28 to 34, the adjusting element is axially displaceable, but torque-resistant guided within the housing. The adjusting element has in its front area on the downstream flow side a threaded opening, in which it engages with a drive element operable from the outside with an internal thread, said drive element is mounted on its front side away from the element. adjustment, on the discharge front side formed by a honeycomb structure of the previously known insertion unit. By unscrewing the drive element out of the threaded opening in the adjusting element, the adjusting element inside the housing of the previously known insertion unit is moved against the flow direction and the free-flow cross-section can be changed so corresponding. By unscrewing the adjusting element and the driving element, however, there is a danger that the housing parts removably engaged with each other are separated from each other by compression and that the previously known functional unit collapses.

[0003] Document DE 94 14 686 describes a device for allowing and stopping a flow of water from a water outlet opening, having a casing that can be connected to said opening and in which are arranged a valve seat, a ring sealing ring and a valve body, which, as a result of water pressure, bears firmly against the sealing ring in a form-fitting manner, and having an actuator by means of which the valve body can be moved from its closed position to its open position and vice versa, and which has at least one member retaining the operating position or cooperating with such a retaining member so that the actuating member can be fixed in its operating position. The operating position retaining member is formed from projections, recesses, control cams, lifting cams and working surfaces that are integrally formed in the actuating member and/or housing and that are in operative connection with each other in operating position. functioning of the actuating member.

[0004] A disadvantage of this solution is that the actuating member of the above-mentioned device passes through the outlet structure of the above-mentioned member on the downstream side approximately in the center and that the actuating member in the open position is located in the center of the emerging water jet. , where the actuating member is not easily detectable and can only be reached with the fingertips while accepting an uncontrolled wave of water flowing over the user's hands.

[0005] Document US 7,017,837 B2 describes a water discharge switching device that is easily miniaturized, easily assembled and manufactured at low cost and seeks to prevent water leaks. The water discharge switching device includes a water foam producing and discharging device having a water inlet, an air/water mixing chamber facing the water inlet and capable of communicating with the water inlet, a port air suction capable of communicating with the air/water mixing chamber, and a water foam outlet. The switching device also includes a shower water discharge device having a shower water discharge port and capable of communicating with the water inlet. The shower water discharge device is arranged around the air/water mixing chamber of the water foam production and discharge device. Furthermore, the water discharge switching device for selectively switching between the water foam discharge of the shower water foam producing device and the water discharge of the shower water discharge device. The water discharge port of the shower water discharge device forms an air suction port of the water foam production and discharge device.

[0006] Document WO 2016/153409 A1 describes a flow limiter for fixing a maximum water flow at an outlet of a mixing tap, wherein the flow limiter in the axial direction comprises a seat which along its periphery is provided with an annular wall and has flow channels disposed within and along said wall, an actuator which is rotatable disposed on the seat, a regulating device in the form of a body with a circumferential envelope surface facing the interior of said annular wall, wherein the actuator comprises means for moving the regulating device in the axial direction, and wherein an annular cavity is formed between walls formed by the envelope surface of the regulating device and the seat wall, wherein the annular cavity is arranged with an O-ring , wherein one of the walls of the annular cavity has axially extending open grooves with a cross-sectional area increasing in the direction of flow, wherein the O-ring in its plane is adapted to slidingly connect with said grooves and adopt one of the predetermined positions in the axial direction along said grooves throughout the rotation of the actuator, and wherein such position corresponds to a maximum flow determined by a cross-sectional area for channels that is limited by the O-ring and the walls of the grooves in the plane of the O-ring.

[0007] Since arbitrary adjustment of a known maximum flow rate of the flow regulator must be avoided, document WO 2016/153409 A1 provides that the flow regulator must first be removed from the respective water conductor so that a groove for the screwdriver required for adjustment to become accessible. Manipulating the flow regulator of WO 2016/153409 A1 was therefore deliberately designed to be more difficult.

[0008] Document WO 2011/147495 A1 refers to a sanitary installation element that can be inserted into a water outlet of a sanitary installation and is kept there freely. A feature of the mounted element according to this invention is that this mounted element has an adjusting device for changing the flow area of the clean section of the assembled element and/or the discharge rate, which adjusting device is operable through at least a control element that is operably arranged on the input side of the mounted element and/or on the output side thereof. The element assembled according to this proposal can be used in a versatile way, in order to reduce production and storage costs.

[0009] The adjusting device includes an elastic accelerator ring. In order to be able to change a relative position between the element carrying the elastic accelerator ring and the circumferential wall having the control profile, an actuating element is provided which, in individual embodiment examples of WO 2011/147495 A1, is arranged on the entrance side face of its insertion unit and, in other examples, it is arranged approximately centrally on the exit side face of this sanitary installation component. These embodiments of the installation element of WO 2011/147495 A1 also present the same disadvantages described above.

[0010] It is therefore an objective to provide a sanitary insertion unit of the type mentioned above, which is characterized by a high level of reliability.

[0011] The achievement of this objective lies in the case of the insertion unit of the type mentioned initially, in the fact that in the drive connection between the drive element and the adjusting element a sliding guide is arranged with at least one conductive inclined surface, which converts a rotational movement of the drive element into an axial adjustment movement of the adjusting element.

[0012] The insertion unit according to the invention includes a functional unit that provides a flow opening for water circulating through the insertion unit. In this case, an adjustment element is provided, which, in order to increase the resistance to the flow formed by the flow opening, is arranged axially adjustable or displaceable towards the inside of the flow opening and also to reduce said resistance, towards the outside of the flow. The adjusting element of the functional unit providing the flow passage opening is in drive connection with a drive element, which is disposed on the flow side downstream of the flow passage opening and can be driven from the outside. In the drive connection between the drive element and the adjusting element, a sliding guide is arranged with at least one conductive inclined surface, which converts a rotational movement of the drive element into an axial adjusting movement of the adjusting element. The insertion unit according to the invention is characterized by high reliability. In this case, with the aid of the insertion unit according to the invention, the amount of water circulating through the insertion unit according to the invention can be limited by adjusting the drive element that can be driven from the outside, or regulated to a maximum adjustable value independently of pressure.

[0013] A preferred embodiment according to the invention provides that the sliding guide formed between the drive element and the adjusting element defines a closed guide track, so that the adjusting element returns to its initial position at the latest after a complete rotation of the drive element, in particular after a half-turn. In this embodiment, handling errors are always avoided because the adjusting element always returns to its original position after a complete rotation. In this case, the drive element can be moved both in the direction of rotation and in the other direction of rotation, without causing damage to the insertion unit according to the invention. Since in this embodiment operational errors are ruled out, the functional reliability of the insertion unit according to the invention is further favored.

[0014] Operational errors can also be ruled out due to the fact that the sliding guide is designed free of bumps. In the case of a bump-free sliding guide, it is possible to rotate the drive element outwards by 360°, whereby the adjusting element returns at most after a complete turn of the drive element to its initial position.

[0015] A finely dosed adjustment of the insertion unit according to the invention is favored if the sliding guide is designed without steps or jumps.

[0016] So that the set water volume cannot be adjusted inadvertently during operation of the insertion unit according to the invention, it is advantageous if a slope of the conductive inclined surface is dimensioned so that the sliding guide is self-locking.

[0017] A structurally simple and therefore preferred embodiment according to the invention provides that the inclined conductive surface forms a segment of a preferably surrounding guide track.

[0018] In order to avoid accidental adjustment of the relative position occupied between the drive element and the adjustment element, an exemplary embodiment according to the invention provides for a coupling mechanism, in particular with at least one ball tongue, with which the drive element and/or the adjustment element can be fixed in different angular positions. In this case, a preferred embodiment according to the invention provides that a part of the engagement mechanism is formed on the sliding guide.

[0019] It may be advantageous if the adjusting element is rotatable and, in particular, rotatably axially mounted on the insert part or a housing part.

[0020] In another embodiment according to the invention, on the other hand, the adjustment element is guided in a torque-resistant, but axially displaceable way along or in the housing part or insertion part.

[0021] It is also possible for the adjusting element with the drive element to be in torque-resistant but axially adjustable drive connection.

[0022] The adjustment element can be brought to the desired adjustment position with little effort when the slide guide has at least one guide shoulder, preferably at least two guide shoulders, which terminate at the conductive inclined surface.

[0023] In this case, a preferred embodiment according to the invention envisages that the one or a guiding shoulder terminating on the conductive inclined surface, in particular, is rigidly connected to the adjusting element. This guide shoulder can, for example, be integrally molded into the adjusting element in one piece.

[0024] In order to be able to implement a rotary movement in the drive element in an axial adjustment movement of the adjustment element, it is advantageous if the adjustment element is movably and/or torque-resistant axially coupled to the drive element, in particular be guided axially in the drive element.

[0025] Design and manufacturing efforts can be significantly reduced if the sliding guide forms a one-sided guide.

[0026] Since with the aid of the sliding guide a rotational movement in the drive element can be converted into an axial adjustment movement of the adjusting element, it may be advantageous if the adjusting element is pressed against the unilateral guide by a pressure of water ingress.

[0027] A particularly simple example of embodiment according to the invention provides that the sliding guide is formed by a thread. In this case, the conductive inclined surface can be formed by a thread pitch.

[0028] A preferred development according to the invention provides that the sliding guide is formed by a threaded connection between the drive element and the adjusting element.

[0029] In order to further simplify design and manufacturing efforts, it may be advantageous if the drive element is rigid, in particular integrally connected to the adjusting element in one piece.

[0030] To regulate the amount of water circulating per unit of time up to an adjustable maximum value, a development according to the invention provides that the functional unit is a flow volume regulator, and that a regulation profile of the flow regulator flow volume, which cooperates with an elastic regulating body for flow volume regulation, is formed in the adjusting element.

[0031] It is advantageous if an opening cross-section of the flow opening is variable with the adjusting element.

[0032] According to another example of embodiment according to the invention, the functional unit is provided to be a throttling valve, in which the adjusting element adjusts a cross-section of the throttling valve opening.

[0033] The partial region of the downstream flow side, which projects over the outlet flow nozzle, of the insertion unit according to the invention, can serve as a drive element, if the drive element forms in a circumference outside of the insert, a gripping surface.

[0034] To form a homogeneous and non-spatter discharge flow jet in the insertion unit according to the invention, it is advantageous if the drive element forms a sieve-shaped or lattice-shaped discharge flow structure, in particular radially in or on a gripping surface.

[0035] A particularly compact and functional embodiment according to the invention envisages that the drive element has a lattice-, network- or honeycomb-shaped discharge flow structure with a plurality of flow openings, the structure of which output flow participates in a rotational movement of the drive element. In this embodiment the drive element has a discharge flow structure, which is designed in the form of a lattice, network or honeycomb and has a plurality of flow passage openings. In these flow passage openings of the discharge flow structure, the circulating water is formed into a homogeneous, non-splashing water jet. In this case, the discharge flow structure is connected to the drive element in such a way and, preferably, integrally formed therein in one piece, so that this discharge flow structure participates in a rotational movement of the drive element.

[0036] An accidental adjustment of the insertion unit according to the invention is prevented when the or a guide track has plateau segments, in which a rotation of the drive element does not cause any axial adjustment of the adjusting element.

[0037] For the same reason, it may be advantageous if the or one guide track has at least one engagement recess for at least one or at least one guide shoulder, which with at least one guide track develops a locking resistance that acts against one turn of the adjustment element.

[0038] Improvements in accordance with the invention will become apparent from the claims in connection with the description and drawings. The invention will be described in more detail below with reference to preferred embodiments.

[0071] Figure 32 shows an alternative embodiment in relation to Figure 31, of drive element and adjustment element.

[0072] In Figures 1 to 31, a sanitary insertion unit is illustrated in embodiments 101, 103, 111, 116, 124 and 127. The sanitary insertion unit 101, 103, 111, 116, 124 and 127 can be inserted at the water outlet 1 of a sanitary flush valve. The embodiments shown here 101, 103, 111, 116, 124 and 127 feature a one-piece or multi-piece housing 2, which can be inserted into a sleeve-shaped discharge flow nozzle 3, said discharge flow nozzle 3 can be removably mounted to the water outlet 1 of the drain valve and in particular removably threaded. In this case, an annular projection or an annular flange 4 is provided on the outer circumference of the housing 2, which rests in the position of use of the insertion units 101, 103, 111, 116, 124 and 127 on the inner circumference of the discharge flow nozzle. in the form of a glove 3 (see Figure 19).

[0073] In Figures 18 and 19 it is shown based on example embodiment 116, by way of example, that in the sleeve-shaped discharge flow nozzle 3, a thread 5 can be provided which is threaded with a counter thread 6 in the end on the outlet flow side of a sanitary flush valve valve body. In this case, at least one tool engagement surface 7 is provided on the outer circumference of the discharge flow nozzle 3, on which a rotating tool and, in particular, a spanner used as a rotating tool can be placed.

[0074] Inside housing 2 of the insertion units 101, 103, 111, 116, 124 and 127, a functional unit is provided, which can be designed as a flow limiting throttling valve (see insertion units 101, 103, 111, 124, 127) or also as a flow regulator that regulates the volume of water circulating per unit of time independently of the pressure, to a maximum value (see insertion unit 116). The functional units provided in the insertion units 101, 103, 111, 116, 124 and 127 provide a flow passage opening 8 configured as an annular slot or regulating slot inside the housing 2. In this case, an adjustment element 9 can be operated on the flow side downstream of the flow passage opening 8 in such a way that this adjusting element 9 for increasing a flow resistance formed by the flow passage opening 8, is axially adjustable into the flow passage opening 8 and to reduce this flow passage resistance, it is adjustable axially away from the flow passage opening 8.

[0075] The adjusting element 9 is in drive connection with a drive element 10, said drive element 10 is arranged on the flow side downstream of the flow passage opening 8 and can be driven from the outside. In the drive connection between the drive element 10 and the adjusting element 9, a sliding guide 11 with at least one conductive inclined surface 12 is arranged, which converts a rotational movement of the drive element 10 into an axial adjustment movement of the adjustment element 9.

[0076] With the help of the insertion units 101, 103, 111, 116, 124 and 127 shown here, not only the amount of circulating water must be limited (insertion units 101, 103, 111, 124 and 127) or regulated independently of the pressure up to a maximum value of the flow capacity (see insertion unit 116 ), - but in the insertion units 101, 103, 111, 116, 124 and 127, the outgoing water must also be formed in a jet of homogeneous, non-splashable and, if necessary, also pearly-smooth discharge flow.

[0077] The insertion units 101, 103, 111, 116, 124 and 127 have, for this purpose, a jet divider disposed on the flow side downstream of the flow passage opening 8, which divides the circulating water into a plurality of individual jets.

[0078] For this purpose, this jet divider has a corresponding number of flow passage holes 13, in which respectively a single jet is formed. The jet divider may be designed as a perforated plate arranged approximately transversely to the direction of flow passage. In the case of insertion units 101, 103, 111, 116, 124 and 127, the jet divider is designed as a diffuser 14, which has a deflecting surface 15 that deflects water flowing through the casing 2 approximately radially outward, which is bounded by an annular wall 16 raised upwards against the direction of flow passage. In the annular wall 16, flow passage holes 13 of this jet divider, spaced from each other in circumferential direction, preferably evenly from each other, are provided.

[0079] The through-holes 13 open into an annular slit 17 that narrows in the flow passage direction that is formed between the diffuser 14 that serves as a jet divider and in particular its annular wall 16 on one side and one diffuser ring 18 which surrounds the diffuser 14 on the other. This diffuser ring 18 can be designed as a separate insert piece insertable into the housing 2 and, in contrast to this, and is molded in this case integrally on the inner circumference of the housing 2.

[0080] As the annular gap 17 formed between the diffuser 14 and the diffuser ring 18 narrows at least in some segments in the direction of flow passage and as the water circulating there undergoes an increase in speed in some segments, it forms accordingly with the Bernoulli equation on the downstream flow side of this slit annulate a negative pressure, through which ambient air inside shell 2 can be drawn in. So that this ambient air can circulate into the housing 2, the housing 2 presents in the direction of water flow passage, preferably immediately below the annular gap 17 and, in particular, below the diffuser ring 18, one and preferably several ventilation openings. 19, said ventilation openings 19 being designed as casing interruptions spaced from each other in a circumferential direction, in particular evenly spaced on the circumferential wall of the casing 2. The aspirated ambient air is mixed inside the casing with the water circulating therein, before The water thus swirled and mixed in the ambient air is formed in a flow rectifier 20 provided on the downstream flow side forming an overall sparkling-smooth jet.

[0081] The flow rectifier 20 may be a network or lattice structure composed of bars that intersect each other at intersection nodes, the bars of which delimit the flow passage openings 21 between them. The flux rectifier 20 may be formed by several lattice or network structures arranged at a short distance from each other. In the case of the insertion units 101, 103, 111, 116, 124 and 127 illustrated here, the flow rectifier 20 is formed by just one such lattice structure, which has honeycomb-shaped flow passage openings 21 here . This lattice structure is formed in one piece in housing 2 and forms its front discharge flow side here. Preferably, immediately below the flow rectifier 20, a casing narrowing is provided that tapers in circumferential cross-section 22, which contributes to the homogenization of the existing water and neutralizes splashes from the existing water jet.

[0082] The insertion units 101, 103, 111, 124 and 127 shown in Figures 1 and 2, 3 to 10 and 11 to 15, 24 to 26 and 27 to 31 have a functional unit incorporated as a throttling valve, in which the opening cross-section of the flow passage opening 8 can be changed with the adjusting element 9. While the adjusting element 9 of the insertion units 101, 103, 124 and 127 at its front end on the supply flow side is extends in the direction of flow passage and is designed in an approximately conical or arrowhead shape, the front end region on the supply flow side of the adjusting element 9 provided in the insertion unit 111 has a substantially cylindrical outer contour , in which depressions are molded that taper to open the flow passage, and are open in relation to the cylindrical circumference and the supply flow side, which are distributed at preferably uniform distances over the circumference of the adjusting element 9.

[0083] The adjustment elements 9 of the insertion units 101, 103, 111, 116, 124 and 127 interact with a plate 23 connected upstream of the adjustment elements 9, in which a central adjustment element opening is provided, preferably 24 In insertion units 101, 103, 124 and 127, the annular flow passage opening 8 is formed between the peripheral edge of the plate 23, which delimits the adjustment element 24 and the adjustment element 9, be increased or reduced through the axial displacement of the adjusting element 9 in its free opening cross-section. In the case of the insertion unit 111, the circumferential edge of the plate 23, which delimits the adjusting element opening 24 respectively in accordance with the axial relative position of the displaceable adjusting element 9 with different sized cross-sections of the flow passage grooves 25 provided for in the adjusting element 9, so that here too the opening cross-section of the flow passage opening 8 delimited by the flow passage slots 25 depending on the axial relative position of the adjustment element 9 can be more or less reduced or increased.

[0084] In the insertion unit 101, the sliding guide provided between the drive element 10 and the adjustment element 9 is formed by an external thread 26 disposed on the outer circumference of the drive element 10 and a complementary counter-thread 27, which is formed in a centrally arranged threaded opening in the diffuser 14. In this case, the thread pitches form a conductive inclined surface, convert a rotational movement of the drive element into an axial displacement of the adjusting element 9, connected here to the drive element 10 preferably in a single piece. In its end region away from the adjusting member 9, the drive member 10 projects into a central drive member opening 28 in the lattice structure on the discharge flow side. In the front area of the drive element 10, a tool engagement surface 29 designed here as a hexagonal socket is provided, into which a rotating tool not shown further can be connected.

[0085] The housings 2 of the insertion units 101, 103, 111, 116, 124 and 127 have at least two housing parts 30, 31, which are detachably connectable to each other and, preferably, engageable to each other. others. As shown by way of example in Figures 18 and 19, the housing part 30 arranged on the downstream flow side projects at least with partial area on the downstream flow side over the discharge flow nozzle 3, so that here the drive element 10 formed by the outer circumference of the housing serves as a gripping surface.

[0086] In the lattice structure on the discharge side that serves as a flow rectifier 20 of the insertion units 103, 111 and 116, a star-shaped coupling pin 32, not round and here in cross-section, is formed. projects into a shaped coupling opening 33 on the adjacent front side of the adjusting element 9. The drive element 10 and the adjusting element 9 are torque-resistant arranged over the coupling pin 32 and in the coupling opening 33, but arranged axially adjustable to each other. A rotational movement in the drive element 10 is thus transmitted via the coupling pin 32 and the coupling opening 33 to the adjusting element 9.

[0087] In the case of insertion units 103, 111, 116, 124 and 127, a rotational force exerted on the outer casing circumference of the casing part 30 that serves as a gripping surface is transmitted to the adjusting element 9. So that the housing part 30 on the downstream flow side that serves as the drive element 10 can be rotated relative to the housing part 31 on the feed flow side - as can be seen in Figures 18 and 19, the annular flange 4 is clamped between the annular boss on the inner circumference of the sleeve-shaped discharge flow nozzle 3 and the opposite front water outlet flow area 1. Thus, while the casing part 31 on the feed flow side clamped from The torque-resistant form cannot be rotated any further, whereas the housing part 30 on the downstream flow side is rotatably retained in the housing part 31.

[0088] It can be seen in Figures 3, 6, 11, 16, 18 to 20, 22, 24 to 26, 27 and 30 that the adjustment element 9 of the functional units 103, 111, 116, 124 and 127 crosses a preferably central access opening 34 in the diffuser 14. In this case, the adjusting element 9 is located with a partially enlarged cross-sectional area or with at least one guide boss 35 and, preferably, two spare guide bosses 35 on opposite sides of the element. of adjustment 9 on a sliding guide formed as a closed guide track 36, which is formed on the supply flow side of the diffuser marginal area 14 delimiting the access opening 34. This closed guide track 36 has at least one increase 37 and at least one depression 38, whose rises 37 and depressions 38 are connected to each other via inclined conductive surfaces 12. The sliding guide 11 defines a closed guide track 36, so that the adjusting element 9, at most, after one rotation complete, but in particular after half a turn, it returns to its starting position. A rotational movement of the adjusting element 9 is converted by the guide shoulders 35 sliding over the guide track 36 into an axial adjusting movement of the adjusting element 9.

[0089] The sliding guide is here designed as a one-sided guide, in which the adjusting element 9 is pressed in particular with its guide shoulders 35 on the guide track 36. The pressure of the upstream flow water in the case of the insertion units 101 , 103 and 111 presses the adjusting element 9 against the unilateral orientation of the guide track 36. In contrast, the adjusting element 9 of the insertion unit 116 is pressed by means of a compression spring 37 against the guide of the guide track 36, the compression spring 37 of which is arranged in an insertion opening 57 in the adjusting element 9 and on the one hand rests on the adjusting element 9 and on the other hand rests on an end screen on the feed flow side 39.

[0090] The insertion units 101, 103, 111, 116, 124 and 127 have a final sieve 39 on the feed flow side which has to remove by filtration the other dirt and lime particles entrained in the water before these dirt particles Dirt inside the housing may impair the function of the insertion units 101, 103, 111, 116, 124 and 127. The guide track 36 has plateau segments 40, in which a rotation of the drive element 10 does not cause any axial displacement of the adjusting element 9. The depressions 38 in the guide track 36 are formed as an engagement cavity for the guide shoulders 35, which engagement cavity with the guide shoulders 35 develops an engagement resistance that acts against a rotation of the adjusting element 9.

[0091] The functional unit provided for in the insertion unit 116 is designed as a flow volume regulator that must regulate the volume of circulating water per unit of time to a maximum adjustable value independently of the pressure. For this purpose, the adjusting element 9 of the insertion unit 116 has an adjusting profile, which has depressions open towards the feed flow side and towards the circumference of the adjusting element, which have a depression cross-section each time. more reduced in the direction of flow passage. The adjustment profile provided for in the adjustment element 9 of the insertion unit 116 interacts with an annular regulating body 40 made of elastic material, which, depending on the pressure of the inflow water, shapes more or less sharply in the depressions of the regulating profile arranged in the adjusting element 9 and thus the flow passage opening 8 between the adjacent marginal region of the plate and the regulating body 40 on the one hand and the adjusting element 9 on the other side.

[0092] It can be seen in Figure 10 that the insertion unit 103 has at least one anti-rotation projection 43 on the outer circumference of its diffuser 14, which engages with an anti-rotation recess 44 on the inner circumference of the diffuser ring 18. Since the part of housing 31 on the supply flow side molded into the diffuser ring 18 in a torque-resistant manner is retained in the water discharge flow 1 of the sanitary discharge valve, the diffuser 14 is protected in a torque-resistant manner when the housing part 30 on the downstream flow side is rotated relative thereto.

[0093] In Figure 10 it can be identified that at least one engagement fin 45 can be formed in a single piece on the housing piece 31 on the feed flow side and in particular on the diffuser ring 18 molded thereon, which cooperates with at least an engagement mold concavity 46 in the inner circumference of the casing part on the downstream flow side towards a locking mechanism. In this case, at least one engagement vane 45 that interacts with the molded engagement concavity 46 provides the user with a sensation of engagement when he rotates the housing part on the downstream flow side. In order to increase and/or refine the engagement sensation, a ball lock may be provided in the free fin end region of the engagement fin 45, which cooperates with a spherical recess in the molded engagement concavity 46. For the same purpose However, it is also possible to provide small recesses in the guide track 36 and, in particular, in the region of its elevations 37 and/or depressions 38, to also convey a feeling of locking when rotating the housing part.

[0094] Since the flow passage opening forms a cross-sectional narrowing and leads to an increase in the velocity of the water circulating through it, it is anticipated to reduce the flow velocity in the area of the diffuser 14 that the flow obstacles 47 connected upstream of the flow passage holes 13 are arranged in the region of their deflection surface 15.

[0095] Furthermore, in the insertion units 124, 127 shown in Figures 24 to 26 and 27 to 31, the housing part 31 on the feed flow side is torque-resistantly secured with its annular flange 4 at the feed outlet. water from a sanitary flush valve, while the downstream casing piece 30 serves as a manually engageable drive element 10 on the externally situated casing circumference. As in the case of the insertion units 103, 111 and 116, the housing part 30 on the downstream flow side that serves as the drive element 10 has a discharge flow structure that forms the front discharge flow side of these units. insertion, with a plurality of honeycomb-shaped flow passage openings 21, the discharge flow structure of which participates in a rotational movement in this drive element 10.

[0096] The insertion unit 124 has a drive element 10, in whose discharge flow structure formed as a flow rectifier on the supply flow side a threaded pin 48 projects against the direction of flow passage. This threaded pin 48 has an external thread, which serves as a sliding guide for the adjusting element 9. The adjusting element 9 therefore has a threaded opening 49 with an internal thread, in whose internal thread the external thread of the threaded pin 48 is screwed down. On the adjusting element 9 at least one guide projection 50 projects laterally, which is guided in an axially displaced manner into an associated axial guide groove 51, said guide groove 51 being provided in the diffuser 14 and being open in relation to the access opening 34 in diffuser 14.

[0097] A rotational movement in the drive element 10 is thus transmitted to the threaded pin 48. Since the adjusting element 9 of the insertion unit 124 is driven in a torque-resistant but axially displaceable manner towards the opening flow passage 34 of the diffuser 14, the rotational movement transmitted to the threaded pin 48 and its external thread that serves as a sliding guide is converted into an axial adjustment movement of the adjusting element 9.

[0098] In a modified embodiment of the insertion unit 124, not shown here, the threaded pin 48 may instead also have an internal thread, onto which the adjusting element 9 is screwed with an external thread.

[0099] In the case of insertion units 124 and 127, the adjusting element 9 is guided in a torque-resistant but axially displaceable manner in the flow passage opening 34 of the diffuser 14. In this case, in the discharge flow structure of the unit insertion 127 a guide pin 52 projects, on the pin circumference of which a sliding guide 11 configured as a slide track is molded. The guide pin 52 projects with its pin-free end into a guide opening 53 which is provided on the front side of the adjusting element 9 facing the discharge flow structure. The adjusting element 9 of the insertion unit 127 has at least one slide bar 54 and, as here, preferably two slide bars 54 disposed on opposite sides of the adjusting element 9, said slide bars 54 sliding over the guide track of the circumferential slide guide. 11 and which leaves the conductive inclined surfaces 12 provided in segments on the guide track, spaced from each other and arranged at different heights from the guide pin 53, during a rotational movement in the drive element 10 so that the adjusting element 9 performs a corresponding adjusting movement in the axial direction. In this case, small depressions 55 are formed in the course of this guide track, into which the sliding bar 54 can engage in such a way that the adjusting position of the adjusting element 9 is protected. In Figures 29 and 30, it can be seen that the guide projections 50 that protrude laterally on the adjusting element 9, which are respectively guided in a guide groove 51, guide the adjusting element 9 into the access opening 34 of the diffuser 14, resistant to torque, but axially displaceable.

[0100] In Figure 31, the sliding guide 11 guided on the circumference of the guide pin 52, circumferentially, can be clearly identified with one of the depressions 55. In Figure 32 a modified embodiment is illustrated in which the guide track that serves as a slide guide is formed by the front edge of the adjusting element 9 facing the discharge flow structure, while a slide bar 56 is molded on the circumference of the guide pin 52. In this case, they can also be provided in the guide track of the slide guide provided. on the front edge of the adjusting element 9, depressions 55, which cooperate as engagement notches with the sliding bar 56.

[0101] The insertion units 101, 103, 111, 116, 124 and 127 presented here form a jet aerator that forms the water that exits into a homogeneous, splash-free and pearly-soft water jet. In these jet aerators, a throttling valve (insertion units 101, 103, 111, 124, 127) or a flow volume regulator (insertion unit 116) is integrated, which limits the volume of water circulating there or the regulates independently of pressure to an adjustable maximum value. In this case, the insertion units 101, 103, 111, 116, 124 and 127 described above stand out due to their high level of functional reliability, economic manufacturability and high ease of operation.
