Description

Sanitary insert unit

The invention relates to a sanitary inserting unit having a functional unit providing a throughflow opening, which has an actuating element, which actuating element is arranged axially displaceably or adjustably in the throughflow opening and out of the throughflow opening, wherein the actuating element is drivingly connected to an actuating element which is drivingly connected to the Downstream of the flow opening arranged and operable from the outside. From EP 2 536 886 Bl is already known a sanitary inserting unit of the type mentioned, which can be used in the water outlet of a sanitary outlet fitting. In order to be able to change the flow cross-section of the insertion unit and / or the volumetric flow of the water flowing through, the known insertion unit has a functional unit which provides a flow-through opening, an adjusting element being arranged axially adjustable in the flow-through opening and out of the flow-through opening. By axial adjustment of the operable on an outflow side of the flow control actuator, the clear flow area of the flow-through can be changed. In an embodiment of the EP 2 536 886 Bl shown in Figures 28 to 34, the actuator is axially displaceable, but rotatably guided inside the housing. The adjusting element has a threaded opening on its downstream end face, in which an externally handleable actuating element engages with an internal thread, which actuating element is supported at its end remote from the adjusting element on the outlet end formed of a honeycomb structure of the known insertion unit. By unscrewing the

Actuating element from the threaded opening in the control element, the adjusting element is displaced in the housing interior of the known insertion unit counter to the flow direction and the clear flow cross-section can be changed accordingly. By unscrewing the adjusting element and the actuating element, however, there is the danger that the housing parts of the housing that are releasably latched to one another are also pressed apart and that the previously known functional unit will fall apart.

It is therefore an object to provide a sanitary inserting unit of the type mentioned above, which is characterized by a high level of reliability. The achievement of this object is in the insertion unit of the type mentioned in particular that in the drive connection between the actuating element and the actuator a sliding guide is arranged with at least one run-on slope, which converts a rotational movement of the actuating element in an axial actuating movement of the actuating element.

The insertion unit according to the invention includes a functional unit which provides a flow-through opening for the water flowing through the insertion unit. In this case, an adjusting element is provided which leads to an increase in a flow resistance formed by the flow-through opening into the flow-through opening and to a reduction the same is arranged axially displaceable or adjustable out of the flow-through. The actuating element of the functional unit providing the flow-through opening is drive-connected to an actuating element which is arranged on the outflow side of the flow-through opening and can be actuated from the outside. In the drive connection between the actuating element and the actuating element, a sliding guide is arranged with at least one starting bevel, which converts a rotational movement of the actuating element into an axial adjusting movement of the actuating element. The insertion unit according to the invention is characterized by a high

Functional safety. By means of the inserting unit according to the invention, the amount of water flowing through the inserting unit according to the invention can be limited by adjusting the actuating element which can be actuated from the outside or adjusted to an adjustable maximum value independently of pressure.

A preferred embodiment according to the invention provides that the sliding guide formed between the actuating element and the actuating element defines a closed guideway, so that the actuating element returns to its starting position at the latest after one complete revolution on the actuating element, in particular after half a revolution. In this embodiment, handling errors are avoided with certainty because the actuator always returns to its original position after one full turn. In this case, the actuating element can be moved both in the one direction of rotation and in the other direction of rotation, without causing malfunction of the insertion unit according to the invention. Since operating errors are ruled out in this embodiment, the functional reliability of the insertion unit according to the invention is additionally favored. Operating errors can also be ruled out by the fact that the sliding guide is designed stop-free. In such an impact-free sliding, it is possible to rotate the actuator over 360 ° out, the actuator returns after a full rotation of the actuator to its original position at the latest.

A finely metered adjustment of the insertion unit according to the invention is favored when the sliding guide is formed without steps or jumps.

So that the set volume of water can not be adjusted unintentionally during operation of the insertion unit according to the invention, it is advantageous if a slope of the run-up slope is dimensioned so that the sliding guide is self-locking.

A structurally simple and therefore preferred embodiment according to the invention provides that the run-on slope forms a portion of a preferably circumferential guideway.

In order to prevent an unintentional adjustment of the relative position assumed between the actuating element and the adjusting element, an embodiment according to the invention provides that a latching mechanism, in particular with at least one ball catch, is formed, with which the actuating element and / or the adjusting element can be fixed in different angular positions is. In this case, a preferred embodiment according to the invention provides that a part of the latching mechanism is formed on the sliding guide.

It may be advantageous if the actuating element rotatable and in particular axially rotatably mounted on the or a housing part or insert part.

In contrast, another embodiment according to the invention provides that the actuating element is rotatably but axially displaceably guided on the or a housing part or insert part.

It is also possible that the actuator with the actuator rotatably, but is axially adjustable in drive connection.

The actuator can be brought into the desired setting position with little effort when the slide has at least one guide projection, preferably at least two guide projections, which run on the run-on slope.

In this case, a preferred embodiment according to the invention provides that the or a running on the run-in slope guide projection rotatably, in particular rigidly connected to the actuating element. This guide projection can for example be integrally formed on the actuating element.

In order to implement a rotational movement on the actuating element in an axial adjusting movement of the actuating element, it is advantageous if the actuating element axially movable and / or rotationally fixed coupled to the actuating element, in particular axially guided on the actuating element. The design and manufacturing effort can be significantly reduced if the slide forms a one-sided leadership. Since a rotational movement on the actuating element can be converted into an axial adjusting movement of the adjusting element with the aid of the sliding guide, it can be advantageous if the actuating element is pressed against the one-sided guidance by an inflow water pressure.

A particularly simple embodiment according to the invention provides that the sliding guide is formed by a thread. In this case, the run-up be formed by a thread of the thread.

A preferred development according to the invention provides that the sliding guide is formed by a screw connection between the actuating element and actuator.

In order to simplify the construction and manufacturing effort even further, it may be advantageous if the actuating element is rigid, in particular integrally connected to the actuating element.

In order to regulate the amount of water flowing through per unit time to an adjustable maximum value, a development according to the invention provides that the functional unit is a flow rate regulator, and that a control profile of the flow rate regulator, which cooperates with an elastic control body for flow rate control, is formed on the control element.

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

According to another embodiment according to the invention it is provided that the functional unit is a throttle, wherein the actuator adjusts an opening cross section of the throttle.

As an actuating element can also serve, for example, via an outlet mouthpiece projecting downstream portion of the inserting unit according to the invention, if the

Actuating element forms a gripping surface on an outer periphery of the insert. In order to form a homogeneous and non-spraying outflow jet in the insertion unit according to the invention, it is advantageous if the actuating element forms a sieve-like or grid-shaped outlet structure, in particular radially inside the or a gripping surface.

A particularly compact and functional embodiment according to the invention provides that the actuating element has a lattice, mesh or honeycomb-shaped outlet structure with a plurality of flow openings, which outlet structure participates in a rotational movement of the actuating element. In this embodiment, the actuating element has an outlet structure, which is formed like a grid, net or honeycomb cell and has a plurality of flow openings. In these flow openings of the outlet structure, the water flowing through is formed into a homogeneous and non-splashing jet of water. In this case, the outlet structure is connected to the actuating element in such a way and preferably integrally formed thereon, that this outlet structure participates a rotational movement of the actuating element.

An unintentional adjustment of the insertion unit according to the invention is avoided if the or a guideway has plateau sections, in which a rotation of the Actuator causes no axial adjustment of the actuating element.

For the same reason, it may be advantageous if the or a guideway has at least one latching recess for at least one or the at least one guide projection, which with the at least one guide projection develops a latching resistance acting against a rotation of the actuating element.

Further developments according to the invention will become apparent from the claims in conjunction with the description and the drawings. The invention will be described in more detail below with reference to preferred embodiments.

Actuator and actuator. FIGS. 1 to 31 show a sanitary inserting unit in the embodiments 101, 103, 111, 116, 124 and 127. The sanitary inserting unit 101, 103, 111, 116, 124 and 127 can be inserted into the water outlet 1 of a sanitary outlet fitting. The embodiments shown here 101, 103, 111, 116, 124 and 127 have a one- or multi-part housing 2, which is insertable into a sleeve-shaped outlet nozzle 3, which outlet nozzle 3 can be detachably mounted on the water outlet 1 of the outlet fitting and in particular releasably screwed , In this case, an annular shoulder or an annular flange 4 is provided on the housing 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 sleeve-shaped outlet mouthpiece 3 (see Figure 19).

In the figures 18 and 19 is shown by way of example with reference to the embodiment 116 that the sleeve-shaped outlet mouthpiece 3, a thread 5 may be provided which can be screwed with a mating thread 6 at the outlet end of a fitting body of the sanitary outlet fitting. In this case, at least one tool engagement surface 7 is provided on the outer circumference of the outlet nozzle 3, on which a rotary tool and in particular a wrench used as a turning tool can be attached.

In the housing interior of the housing 2 of the insertion units 101, 103, 111, 116, 124 and 127, a functional unit is provided which serves as a flow-restricting restrictor (cf., insertion units 101, 103, 111, 124, 127) or as a water volume flowing through per unit time independent of pressure to a maximum value adjusting flow rate controller (cf.

Insertion unit 116) may be formed. The in the Inserting units 101, 103, 111, 116, 124 and 127 provided functional units provide in the housing interior of the housing 2 to a designed as an annular gap or control gap through-flow 8 ready. In this case, an actuating element 9 can be actuated on the outflow side of the flow-through opening 8 in such a way that this control element 9 is axially adjustable for increasing a flow resistance formed by the flow-through opening 8 into the flow-through opening 8 and for reducing this flow resistance from the flow-through opening 8.

The actuating element 9 is in drive connection with an actuating element 10, which actuating element 10 is arranged on the outflow side of the throughflow opening 8 and can be actuated from the outside. In the drive connection between the actuating element 10 and the adjusting element 9, a sliding guide 11 is arranged with at least one run-on slope 12, which converts a rotational movement on the actuating element 10 into an axial adjusting movement of the actuating element 9.

With the help of the insertion units 101, 103, 111, 116, 124 and 127 shown here, not only the amount of water flowing through is limited (insertion units 101, 103, 111, 124 and 127) or adjusted independently of pressure to a maximum value of the flow capacity (see insertion unit 116 ), - Rather, in the inserting units 101, 103, 111, 116, 124 and 127, the outflowing water should also be formed into a homogeneous, non-spraying and, if necessary, also bead-like, outflow stream.

The insertion units 101, 103, 111, 116, 124 and 127 have for this purpose a arranged on the outflow side of the flow-through 8 jet separator, which is the water flowing through divided into a variety of individual beams.

For this purpose, this jet separator has a corresponding number of flow holes 13, in each of which a single jet is formed. The jet splitter could be designed as a perforated plate arranged approximately transversely to the direction of flow. In contrast, in the case of the insertion units 101, 103, 111, 116, 124 and 127, the jet splitter is designed as a diffuser 14, which has a deflecting surface 15 which deflects the water flowing through the housing 2 approximately radially outwards and which moves upwards from an annular wall raised counter to the throughflow direction 16 is bounded. In the annular wall 16, the flow holes 13 of this jet separator which are preferably spaced apart from one another in the circumferential direction are provided so as to be uniformly spaced from one another.

The flow holes 13 open into a narrowing in the flow direction annular gap 17 which is formed between the serving as a beam splitter diffuser 14 and in particular its annular wall 16 on the one hand and a diffuser 14 surrounding the diffuser ring 18 on the other. This diffuser ring 18 can be designed as a separate insertion part which can be inserted into the housing 2 and, in contrast thereto, is integrally formed integrally with the housing inner circumference of the housing 2.

Since the annular gap 17 formed between the diffuser 14 and the diffuser ring 18 at least partially narrows in the flow direction and since the water flowing through it experiences a speed increase in certain regions, a negative pressure, according to the Bernoulli equation on the downstream side of this annular gap, by means of the ambient air into the housing interior of the housing. 2 can be sucked. So that these Ambient air can flow into the housing 2, the housing 2 in the direction of flow of water preferably immediately below the annular gap 17 and in particular below the diffuser ring 18 and preferably a plurality of ventilation openings 19, which ventilation openings 19 as from each other in the circumferential direction in particular uniformly spaced housing openings in the peripheral wall of the housing 2 are formed. The sucked ambient air is mixed inside the housing with the water flowing through, before the so swirled and mixed in the ambient air water provided in a downstream side

Flow rectifier 20 is formed into a bead-soft overall jet. The flow straightener 20 may be a grid or net structure of webs crossing each other at intersection nodes, which webs delimit flow openings 21 between them. The flow rectifier 20 may be formed of a plurality of such, arranged at a small distance from each grid or network structures. In the case of the insertion units 101, 103, 111, 116, 124 and 127 illustrated here, the flow rectifier 20 is formed by only one such lattice structure, which has honeycomb-shaped throughflow openings 21 here. This grid structure is integrally formed on the housing 2 and forms here its outlet front side. Preferably immediately below the flow straightener 20 is a circumferential Querschnittsverengende

Housing constriction 22 is provided, which contributes to the homogenization of the exiting water and counteracts a squirting of the exiting water jet.

The insertion units 101, 103, 111, 124 and 11 shown in FIGS. 1 and 2, 3 to 10 and 11 to 15, 24 to 26 and 27 to 31 127 have a trained as a throttle functional unit, in which the opening cross-section of the flow opening 8 is changed with the adjusting element 9. While the adjusting element 9 of the insertion units 101, 103, 124 and 127 at its inflow-side end face widens in the direction of flow and is approximately conical or arrowhead-shaped, the inflow-side front end region of the positioning element 111 provided in the insertion unit 9 has a substantially cylindrical outer contour, are formed in which the cylinder circumference and the inflow side open and tapered in flow-through depressions are formed, which are distributed in preferably uniform intervals over the circumference of the actuating element 9. The adjusting elements 9 of the insertion units 101, 103, 111, 116, 124 and 127 cooperate with a the upstream of the adjusting elements 9 upstream plate 23 in which a preferably central actuator opening 24 is provided. In the insertion units 101, 103, 124 and 127 forms between the actuator opening 24 bounding peripheral edge of the plate 23 and the actuator 9, the annular flow opening 8, which can be increased or reduced by axially adjusting the actuator 9 in its clear opening cross-section , In the case of the insertion unit 111, the peripheral edge of the plate 23 delimiting the actuating element opening 24 cooperates with differently sized cross sections of the flow grooves 25 provided in the adjusting element 9, depending on the axial relative position of the adjustable adjusting element 9, so that here too the opening cross section of the throughflow opening bounded by the flow-through grooves 25 8 depending on the axial relative position of the actuating element 9 can be more or less reduced or increased. In the insertion unit 101, the sliding guide provided between the actuating element 10 and the adjusting element 9 is formed by an external thread 26 arranged on the outer circumference of the actuating element 10 and a complementary mating thread 27 which is formed in a threaded opening arranged centrally in the diffuser 14. In this case, the threads form a run-on slope, which converts a rotational movement of the actuating element into an axial adjustment of the actuating element 10, which is preferably integrally connected here with the actuating element 9. At its end region facing away from the adjusting element 9, the actuating element 10 protrudes into a central actuating element opening 28 in the outlet-filling grid structure. At the end face of the actuating element 10, a tool engagement surface 29 designed here as a hexagon socket is provided, on which a turning tool (not shown further) can be attached.

The housings 2 of the insertion units 101, 103, 111, 116, 124 and 127 have at least two housing parts 30, 31, which are releasably connectable to each other and preferably latched together. As is shown by way of example in FIGS. 18 and 19, the downstream housing part 30 protrudes at least with its outflow-side partial area via the outlet mouthpiece 3, so that here the actuating element 10 is formed by the housing outer circumference serving as gripping surface.

On the inflow side serving as a flow rectifier 20 Auslaufseifigen grid structure of the inserting units 103, 111 and 116 a non-round and here in cross-section approximately star-shaped coupling pin 32 is formed, which projects into a shape-matched coupling opening 33 on the adjacent end face of the actuating element 9. The actuating element 10 and the actuating element 9 are via the coupling pin 32 and the coupling opening 33 rotatably but axially adjustable to each other. A rotational movement on the actuating element 10 is thus transmitted via the coupling pin 32 and the coupling opening 33 on the adjusting element 9.

In the case of the insertion units 103, 111, 116, 124 and 127, a rotational force exerted on the housing outer circumference of the housing part 30 serving as a gripping surface is transmitted to the adjusting element 9. Thus, serving as the actuator 10 downstream housing part 30 can be rotated relative to the inflow-side housing part 31 is - as can be seen in Figures 18 and 19, the annular flange 4 between the annular shoulder on the inner circumference of the sleeve-shaped outlet nozzle 3 and the opposite end face of the water outlet 1 clamped , Thus, while the rotatably clamped inflow-side housing part 31 can not be rotated further, the outflow-side housing part 30 is rotatably held on the housing part 31 on the other hand. It is clear from FIGS. 3, 6, 11, 16, 18 to 20, 22, 24 to 26, 27 and 30 that the actuating element 9 of the functional units 103, 111, 116, 124 and 127 has a preferably central through-opening 34 in the diffuser 14 interspersed. In this case, the adjusting element 9 is located with a cross-sectional widened portion or at least one guide projection 35 and preferably two, on opposite sides of the actuating element 9 projecting guide projections 35 on a trained as a closed guide track 36 sliding on the inflow side of the passage opening 34 bounding edge region of the diffuser 14 is formed. This closed guide track 36 has at least one elevation 37 and at least one recess 38, which elevations 37 and depressions 38 via run-on slopes 12 connected to each other. The sliding guide 11 defines a closed guide track 36, so that the actuating element 9 at the latest after one full turn, but in particular after half a turn, returns to its original position. A rotational movement of the actuating element 9 is converted by the sliding on the guide track 36 guide projections 35 in an axial adjusting movement of the actuating element 9.

The sliding guide is here designed as a one-sided guide, in which the adjusting element 9 is pressed in particular with its guide projections 35 onto the guide track 36. In this case, the Anströmwasserdruck presses in the insertion units 101, 103 and 111, the adjusting element 9 against the one-sided guidance of the guide track 36. In contrast, the actuator 9 of the inserting unit 116 is pressed by a compression spring 37 against the guide of the guide track 36, which compression spring 37 in an insertion 57th is arranged in the adjusting element 9 and on the one hand on the adjusting element 9 and on the other hand on an inflow-side facing screen 39 is supported.

The insertion units 101, 103, 111, 116, 124 and 127 have such an inflow-side attachment screen 39 which has to filter out the lime and other dirt particles entrained in the water before these dirt particles inside the housing function as inserting units 101, 103, 111, 116 , 124 and 127 can affect. The guideway 36 has plateau sections 40, in which a rotation of the actuating element 10 causes no axial adjustment of the actuating element 9. The depressions 38 in the guide track 36 are formed as a latching depression for the guide projections 35, which latching recess with the guide projections 35 develops a latching resistance acting against a rotation of the actuating element 9. The functional unit provided in the insertion unit 116 is designed as a flow rate regulator which is intended to adjust the water volume flowing through per unit of time to an adjustable maximum value independently of pressure. For this purpose, the adjusting element 9 of the inserting unit 116 has a control profile which has open depressions towards the inflow side and the actuating element circumference, which depressions have an increasingly reduced depression cross section in the direction of flow. The control profile provided on the adjusting element 9 of the inserting unit 116 interacts with an annular regulating body 40 made of elastic material, which, depending on the pressure of the inflowing water, molds more or less strongly into the depressions of the control profile arranged on the adjusting element 9 and thus the flow-through opening 8 between the adjacent edge region of the plate and the control body 40 on the one hand and the adjusting element 9 on the other changed.

In FIG. 10, it can be seen that the insertion unit 103 has at least one at the outer circumference of its diffuser 14

Anti-rotation projection 43 has, in a

Anti-rotation recess 44 engages the inner circumference of the diffuser ring 18. Since the molded onto the inflow-side housing part 31 diffuser ring 18 is rotatably held on the water outlet 1 of the sanitary outlet fitting, and the diffuser 14 is secured against rotation when the outflow-side housing part 30 is rotated relative thereto.

In FIG. 10, it can be seen that at least one snap tab 45 can be formed on the inflow-side housing part 31 and in particular the diffuser ring integrally formed thereon, with at least one snap recess 46 on the inner circumference of the downstream housing part in the sense of FIG a Rastmachanik cooperates. The cooperating with the Schnappeinformungen 46, at least one snap tab 45 gives the user a locking feel when it rotates the downstream housing part. In order to increase and / or refine the latching feel, a ball catch can be provided on the free flap end region of the snap tab 45 which cooperates with a spherical recess in the snap shaping 46. For the same purpose, however, it is also possible to provide small depressions in the guide track 36 and in particular in the region of their elevations 37 and / or depressions 38, in order to likewise impart a locking feeling when the lower housing part is rotated.

Since the flow-through opening forms a cross-sectional constriction and leads to an increase in the velocity of the water flowing through it, it is provided to reduce the flow velocity in the area of the diffuser 14 that flow obstacles 47 upstream of the flow-through holes 13 are arranged in the region of its deflection surface 15.

Also, in the insertion units 124, 127 shown in Figures 24 to 26 and 27 to 31, the inflow-side housing part 31 is rotatably held with its annular flange 4 at the water outlet of a sanitary outlet fitting, while the downstream housing part 30 as a on the outer housing circumference manually tangible actuator 10th serves. As in the case of the insertion units 103, 111 and 116, the outlet-side housing part 30 serving as the actuating element 10 has a discharge structure forming the outlet end side of these insertion units, with a plurality of honeycomb-shaped throughflow openings 21, which outlet structure participates in a rotational movement on this actuating element 10. The insertion unit 124 has an actuating element 10, on whose run-off structure formed as a flow rectifier on the inflow side a threaded pin 48 protrudes counter to the flow direction. This threaded pin 48 has an external thread, which serves as a sliding guide for the adjusting element 9. The actuator 9 has to a threaded opening 49 with an internal thread, in which internal thread, the external thread of the threaded pin 48 is screwed. On the adjusting element 9 is at least one guide projection 50 laterally, which is axially displaceably guided in an associated axial guide groove 51, which guide groove 51 provided in the diffuser 14 and the passage opening 34 in the diffuser 14 is open.

A rotational movement on the actuating element 10 is thus transmitted to the threaded pin 48. Since the adjusting element 9 of the insertion unit 124 rotatably, but axially displaceably guided in the passage opening 34 of the diffuser 14, which is transmitted to the threaded pin 48 and serving as a sliding outer thread rotational movement is converted into an axial actuating movement of the actuating element 9.

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

In the insertion units 124 and 127, the actuator 9 is rotatably, but axially displaceable in the passage opening 34 of the diffuser 14 out. It stands on the outlet structure of the insertion 127 a guide pin 52 before, on the pin circumference configured as a slide track slide 11 is formed. The guide pin 52 projects with its free end of a pin in a guide opening 53, which at the Outflow structure facing end face of the actuating element 9 is provided. The adjusting element 9 of the inserting unit 127 has at least one sliding web 54 and, as here, preferably two sliding webs 54 arranged on opposite sides of the adjusting element 9, which slide webs 54 slide on the guideway of the circumferential sliding guide 11 and which are spaced from each other on the guideway and arranged at different heights of the guide pin 53 chamfers 12 during a rotational movement on the actuating element 10 such abfährt that the actuator 9 performs a corresponding adjusting movement in the axial direction. In this case, small depressions 55 are formed in the course of this guideway, in which the slide bar 54 can engage such that the setting position of the actuating element 9 is secured. In FIGS. 29 and 30, it can be seen that the guide projections 50 projecting laterally on the adjusting element 9, each guided in a guide groove 51, rotationally secure the adjusting element 9 in the passage opening 34 of the diffuser 14, but guide it in an axially displaceable manner.

In Figure 31, the circumference of the guide pin 52 circumferentially mentioned sliding guide 11 with one of the wells 55 can be clearly seen. FIG. 32 illustrates a modified embodiment in which the guide track serving as a sliding guide is formed by the end edge of the adjusting element 9 facing the outlet structure, while a sliding web 56 is formed on the circumference of the guide pin 52. It can also be 55 provided in the guideway of the provided at the front edge of the actuating element slide 55, which cooperate as notches with the sliding web 56.

The insertion units 101, 103, 111, 116, 124 shown here and 127 form a jet aerator, which forms the exiting water to a homogeneous, non-splashing and pearly-soft water jet. In these jet aerators, a throttle (insertion units 101, 103, 111, 124, 127) or a flow rate regulator (insertion unit 116) is integrated, which limits the volume of water flowing through or regulated pressure-independent to an adjustable maximum value. In this case, the insertion units 101, 103, 111, 116, 124 and 127 described here are characterized by high reliability, cost-effective manufacturability and high ease of use.
