Et i fig. 1 vist spærreorgan har et hus 10, som har en nedre gevindsektion 12 til fastgørelse af huset til en tilførselsledning eller lignende. Endvidere har huset 10 ved den nedre ende en aksial indløbspassage 14 og ved 20 den øvre ende et gevind 16 til en overløbermøtrik 18, der fastholder spærreorganets indre dele i huset.One in FIG. 1 has a housing 10 having a lower thread section 12 for securing the housing to a supply line or the like. Further, the housing 10 has at its lower end an axial inlet passage 14 and at its upper end a thread 16 for an overflow nut 18 which retains the inner parts of the locking member in the housing.
Spærreorganet har endvidere en spindel 20 med et nedadtil åbent kammer 22 i den nedre del. Spindlen 20 er mon-25 teret i en bøsning 24, som igen er monteret inde i huset 10. Bøsningen kan have en udadragende rand 26, som er fastholdt mellem husets 10 øvre ende og overløbsmøtrikken 18. Randen 26 er udformet med et nedadrettet fremspring 28, som indgriber med et indhak i huset, således 30 at bøsningen 24 fastholdes ikke drejeligt, hvorved det sikres, at vand kan passere gennem spærreorganet og udad gennem en udløbsport 30 i huset.The locking means further has a spindle 20 with a downwardly open chamber 22 in the lower part. The spindle 20 is mounted in a sleeve 24 which is again mounted inside the housing 10. The sleeve may have an outwardly extending rim 26 which is held between the upper end of the housing 10 and the overflow nut 18. The rim 26 is formed with a downwardly projecting 28 which engages with a notch in the housing such that the sleeve 24 is not pivotally secured, thereby ensuring that water can pass through the locking means and outwardly through an outlet port 30 in the housing.
Bøsningen 24 har en åben bund. Spindlen 20 har ligeledes 35The sleeve 24 has an open bottom. The spindle 20 also has 35
DK 155626 BDK 155626 B
4 i den nedre ende en åbning 34, der fører ind til kammeret 22. Spindlen 20 har endvidere en radial udløbsport 36, som kan bevæges, således at den kommer ud for i en bøsningen udformet udløbsport 38. Denne består af en i 5 omkredsen forløbende slids 40 og en i det væsentlige cirkelformet gennemløbsport 42. Kombinationen af slidsen 40 og gennemløbsporten 42 muliggør styret gennemstrømning.4, at the lower end, an opening 34 leading to the chamber 22. The spindle 20 further has a radial outlet port 36 which can be moved to open an outlet port 38 formed in a sleeve. slot 40 and a substantially circular passage port 42. The combination of slot 40 and passage port 42 enables controlled flow.
10 En tætningsring 44 er anbragt i en åbning 46 i bøsningen 24 og kan ikke bevæges hverken i forhold til spindlen eller bøsningen. En cylindrisk tætningsstøtte 48, der strækker sig omkring bøsningen, har et par store, overfor hinanden beliggende åbninger 50 og 52, se fig. 2 og 15 3, der holdes adskilt af et trin 54. Gennem åbningerne 50 og 52 strømmer vand fra bøsningens og spindlens udløbsport til husets udløbsport 20. I bunden af tætningsstøtten 48 er der udformet åbninger 49, hvorved der tilvejebringes strømningsforbindelse mellem husets indløbs-20 passage 14 og bøsningen. Åbningerne 49 tjener også til at forhindre store genstande i at komme ind i spærreorganets indre.A sealing ring 44 is arranged in an opening 46 in the bush 24 and cannot be moved either relative to the spindle or bush. A cylindrical seal support 48 extending around the sleeve has a pair of large, opposite openings 50 and 52, see FIG. 2 and 15 3, which are separated by a step 54. Through the openings 50 and 52, water flows from the outlet port of the sleeve and the spindle to the outlet port of the housing 20. At the bottom of the sealing support 48, openings 49 are provided, thereby providing flow connection between the inlet 20 of the housing. passage 14 and the bushing. The openings 49 also serve to prevent large objects from entering the interior of the locking means.
Spindlen 20 er i tætnende indgreb med bøsningen 24 gen-25 nem en øvre ringtætning 56, der er monteret i en rundt-gående rille 58 på spindlen, og en nedre ringtætning 60, der ligger mellem en skulder 62 på tætningsstøtten 48 og bøsningens 24 nedre ende. Bøsningens 24 ydre holdes i tætnende anlæg mod huset 10 gennem en øvre tætning 64 i 30 en ringrille 66 og en nedre tætning 68 i en ringrille 70 i støtten 48. Som det især fremgår af fig. 1, danner den nedre del af tætningsstøtten 48, der sammen med bøsningen 24 danner en indsats, et indløb for spærreorganet og er beliggende umiddelbart nær ved en skulder 72, der er 35The spindle 20 is sealingly engaging the bush 24 through an upper ring seal 56 mounted in a circumferential groove 58 on the spindle and a lower ring seal 60 located between a shoulder 62 on the seal support 48 and the bottom of the bush 24 end. The outer surface of the sleeve 24 is held in sealing abutment against the housing 10 through an upper seal 64 in 30 an annular groove 66 and a lower seal 68 in an annular groove 70 in the support 48. As can be seen in particular in FIG. 1, the lower portion of the sealing support 48, which together with the sleeve 24 forms an insert, forms an inlet for the locking member and is located immediately adjacent to a shoulder 72 which is 35

5 udformet i husets 10 nedre del.5 formed in the lower part of the housing 10.
Den af spindlen, bøsningen og tætningsstøtten dannede indsats holdes sammen ved hjælp af en kile 74. I støtten 5 48 er der udformet en slids 76 til optagelse af kilen.The insert formed by the spindle, bushing and sealing support is held together by a wedge 74. In the support 5 48, a slot 76 is formed for receiving the wedge.
Kilen 74 har et par fingre 80 og 82, som kan føres gennem en slids 84 i bøsningen og ind i en ringrille 86 i spindlen, og som griber omkring et mellemstykke 84 på spindlen. Som vist mere detaljeret i fig. 4 har kilens 10 74 fingre 80 og 82 let divergerende indre kanter hen holdsvis 80a og 82a, så at kilen let kan føres gennem de nævnte slidser ind i den i fig. 4 viste låsestilling.The wedge 74 has a pair of fingers 80 and 82 which can be passed through a slot 84 in the sleeve and into a ring groove 86 in the spindle and which grip about an intermediate piece 84 on the spindle. As shown in more detail in FIG. 4, the fingers 80 and 82 of the wedge 10 74 have slightly divergent inner edges, respectively 80a and 82a, so that the wedge can be easily passed through said slots into the one shown in FIG. 4.
Der findes små recesser 77 og 79 nær den pågældende slids i tætningsstøtten og bøsningen, således at der er 15 adgang til et lille hul 83 i toppen af kilen til aftagning af denne. Efter udtagning af kilen kan indsatsen skilles ad til udskifning af tætningerne.Small recesses 77 and 79 are located near the slot in question in the sealing support and bushing, so that there is access to a small hole 83 at the top of the wedge for removing it. After removing the wedge, the insert can be disassembled to replace the seals.
Den øvre ende af spindlen 20 har tre plane sideflader 20 87. Bøsningen 24 er forsynet med et opad ragende frem spring 88 til begrænsning af spindlens rotationsområde.The upper end of the spindle 20 has three flat side faces 20 87. The sleeve 24 is provided with an upwardly projecting spring 88 to limit the spindle's rotational range.
Et håndtag kan kun orienteres i én stilling på stammen p.g.a. de tre plane sideflader. Når håndtaget er anbragt i denne stilling, kan det kun bevæges en lille smule og 25 i bestemte retninger mellem åben og lukket stilling.A handle can only be oriented in one position on the stem due to the three planar side faces. When the handle is placed in this position, it can only be moved slightly and 25 in certain directions between open and closed positions.
Dette sikrer, at spærreorganet kun kan åbnes i én retning og kun lukkes ved bevægelse i den modsatte retning.This ensures that the locking means can only be opened in one direction and closed only by movement in the opposite direction.
Boringen i tætningsstøtten har ved den øvre ende en let 30 udvidelse 51, således at tætningsstøtten lettere kan skydes på bøsningen 24 og tætningsringen 44. Tætningsstøtten er i det mindste skubbet et stykke op på bøsningen, før førstnævnte begynder at sammentrykke tætningen. Tætningen er således sikkert fastholdt, før der 35The bore in the sealing support has at its upper end a slight extension 51, so that the sealing support can be more easily pushed on the bushing 24 and the sealing ring 44. The sealing support is at least pushed up the bushing before the former begins to compress the seal. Thus, the seal is securely retained before 35

6 udøves noget tryk på den. På spindlen 20 og bøsningen 24 er der, som vist detaljeret i fig. 1, udformet komplementære skuldre henholdsvis 20a og 24a. Disse skuldre ligger lige over for området for kilen 74. Denne anbrin-5 gelse er særlig fordelagtig ved indsætning af spindlen i bøsningen. For det første kan tætningsringen 56 let bevæges med spindlen, når denne føres ind i den nedre åbning i bøsningen. For det andet hindrer de komplementære skuldre, at spindlen blæses ud af bøsningen i tilfælde 10 af, at kilen 74 ikke er blevet ført ordentligt ind.6 some pressure is exerted on it. On the spindle 20 and the bush 24, as shown in detail in FIG. 1, complementary shoulders 20a and 24a respectively. These shoulders lie just opposite the region of the wedge 74. This arrangement is particularly advantageous when inserting the spindle into the bushing. First, the sealing ring 56 can be easily moved with the spindle as it is inserted into the lower opening of the sleeve. Second, the complementary shoulders prevent the spindle from being blown out of the bushing in case 10 of the wedge 74 not being properly inserted.
Ydermere tjener skuldrene til at positionere spindlen i forhold til bøsningen, før kilen 74 indsættes.Furthermore, the shoulders serve to position the spindle relative to the bushing before the wedge 74 is inserted.
Spærreorganets lukkede stilling er vist i fig. 1. Spind-15 lens udløbsport 36 ligger her inden for tætningsringen 44, som således danner lukketætning. Når spindlen roteres mod uret bort fra den viste stilling, kommer udløbsporten 36 først i forbindelse med slidsen 40 for bøsningens udløbsport 38, hvilket tillader en lille mængde 20 vand at slippe ud. Ved fortsat rotation af spindlen i samme retning vil dens udløbsport 36 til sidst flugte med den udvidede gennemløbsport 42, så at den størst mulige mængde kan strømme ud. Vandet strømmer ud gennem gennemløbsporten 42, derpå gennem åbningerne 50 og 52 i 25 tætningens støtte og derpå ud gennem husets udløbsport 30.The closed position of the locking means is shown in FIG. 1. The outlet port 36 of the spindle 15 lies here within the sealing ring 44, thus forming a seal. When the spindle is rotated counterclockwise away from the position shown, the outlet port 36 first comes into contact with the slot 40 of the outlet port 38 of the sleeve, allowing a small amount of 20 water to escape. By continuing rotation of the spindle in the same direction, its outlet port 36 will eventually align with the extended through port 42 so that the greatest amount of flow can flow out. The water flows out through the passage port 42, then through the openings 50 and 52 in the sealing support and then out through the outlet port 30 of the housing.
Den beskrevne konstruktion har den særlige fordel, at tætningsringen 44 ikke bevæges sammen med spindlen, men 30 derimod holdes stationær. Tætningsringen vil derfor ikke blive slidt eller på anden måde lide skade ved aktivering af spærreorganet. Tætningen ligger ikke i vandets strømningsbane og kan derfor ikke blive flyttet af vandtrykket, og den kommer heller ikke i berøring med frem-35The construction described has the special advantage that the sealing ring 44 is not moved together with the spindle, but 30 is held stationary. The sealing ring will therefore not be worn or otherwise suffer damage by activating the locking means. The seal does not lie in the flow path of the water and therefore cannot be moved by the water pressure, nor does it come into contact with the flow.

Tætningen giver således en sikker lukning af spærreorganet, men på en sådan måde, at tætningen ikke udsættes for slitage og følgelig har en lang levetid.7 bodies in the water stream. The seal thus provides a secure closure of the locking member, but in such a way that the seal is not subject to wear and consequently has a long life.

Kilen holder ikke blot tætningsstøtten og bøsningen sammen, men fastholder også spindlen inde i bøsningen, så at spindlen ikke kan bevæges frem og tilbage i længderetningen og ikke kan presses ud af bøsningen ved vand-10 trykket. Kilen sikrer endvidere, at spindlen ikke kan skubbes så langt ind i bøsningen, at den umuliggør aktivering af spærreorganet.The wedge not only holds the sealing support and bushing together, but also holds the spindle inside the bushing so that the stem cannot be moved back and forth longitudinally and cannot be pushed out of the bushing at the water pressure. The wedge further ensures that the spindle cannot be pushed so far into the bush as to make it impossible to activate the locking member.
I fig. 7, 8 og 9 er der vist en modificeret udførelses-15 form af spærreorganet ifølge opfindelsen. Spindlens nedre del er vist i fig. 8 og har en ringrille 106 i lille afstand fra den nedre ende 108. En tætningsring 110 er anbragt i ringrillen 106 og danner tætning mellem spindlens nedre ende og et stempel 112 af f.eks. rustfrit 20 stål eller lignende. Stemplet 112 har en åben nedre ende 114, der ligger over for åbninger 104 i tætningsstøtten, hvorved vand kan strømme ind i stemplets indre. Omiddelbart over tætningsringen 110 har spindlen flere indhak 116 til indgreb med på stemplet 112 udformede fremspring 25 118, ved hjælp af hvilke stemplet er fastgjort til spindlen. En O-ring 120 er anbragt mellem bøsningens nedre ende 122 og en indre skulder 124 på tætningsstøtten 100.In FIG. 7, 8 and 9, a modified embodiment of the locking means according to the invention is shown. The lower part of the spindle is shown in FIG. 8 and has a ring groove 106 at a small distance from the lower end 108. A sealing ring 110 is arranged in the ring groove 106 and forms a seal between the lower end of the spindle and a piston 112 of e.g. stainless steel or the like. The plunger 112 has an open lower end 114 which faces the openings 104 in the sealing support, whereby water can flow into the interior of the plunger. Immediately above the sealing ring 110, the spindle has several notches 116 for engagement with projections 25 118 formed on the piston 112 by means of which the piston is attached to the spindle. An O-ring 120 is disposed between the lower end 122 of the sleeve and an inner shoulder 124 of the sealing support 100.
30 Den i fig. 7, 8 og 9 viste konstruktion fungerer på samme måde som den ovenfor beskrevne. Stemplet af rustfrit stål har en hård overflade, der kan bevæges til anlæg med tætningsringen, som bæres af bøsningen og tætningsstøtten. I den i fig. 1-6 viste konstruktion er spindlen 35The embodiment of FIG. 7, 8 and 9 operate in the same manner as described above. The piston made of stainless steel has a hard surface that can be moved to systems with the sealing ring, which is carried by the bushing and the sealing support. In the embodiment shown in FIG. 1-6, the spindle is 35

8 udelukkende fremstillet af et plastmateriale. Undertiden kan små partikler blive indespærret i plasten, og når spindlen bevæges, kan sådanne partikler slibe eller skære tætningen, således at spærreorganet til sidst bliver 5 utæt. Ved stemplet af rustfrit stål elimineres risikoen for en sådan slitage, så at tætningen ikke slides, når spindlen bevæges mellem den åbne og den lukkede stilling.8 made exclusively of a plastic material. Sometimes, small particles can become entrapped in the plastic and as the spindle is moved such particles can grind or cut the seal so that the locking member eventually becomes leaky. With the stainless steel piston, the risk of such wear is eliminated so that the seal does not wear out when the spindle is moved between the open and closed positions.
10 Den i fig. 10 viste konstruktion er identisk med den i fig. 7-9 viste bortset fra udformningen af indløbsenden for stemplet af rustfrit stål. Stemplet 130 har et endestykke 132 med en reduceret diameter, der afgrænser indløbet i spindlen. En på inderstykket 134 anbragt tæt-15 ningsring 134 har samme funktion som tætningsringen 120 i den i fig. 7-9 viste konstruktion. På grund af endestykkets reducerede diameter har den en mindre diameter end tætningsringen 120 i fig. 7-9, så at friktionsmodstanden ved aktivering af spindlen nedsættes i nogen 20 grad . Skønt indløbet her faktisk er mindre end i de andre udførelsesformer for opfindelsen, hindrer dette på ingen måde en tilfredsstillende drift af spærreorganet.10 The embodiment of FIG. 10 is identical to that of FIG. 7-9 except for the design of the inlet end for the stainless steel piston. The piston 130 has a reduced diameter end piece 132 which defines the inlet of the spindle. A sealing ring 134 located on the inner piece 134 has the same function as the sealing ring 120 in the embodiment shown in FIG. 7-9. Due to the reduced diameter of the end piece, it has a smaller diameter than the sealing ring 120 in FIG. 7-9 so that the frictional resistance upon activation of the spindle is reduced to some 20 degrees. Although the inlet here is actually smaller than in the other embodiments of the invention, this in no way hinders a satisfactory operation of the locking means.
Den i fig. 11 og 12 viste konstruktion ligner den i 25 fig. 7-9 viste med undtagelse af, at der findes to tætningsringe beliggende diametralt modsat hinanden på hver sin side af spindlen. Spindlen 111, som har et stempel af rustfrit stål, er forsynet med et par diametralt modsat hinanden liggende udløbsporte 113 og 115, hvilket 30 ses bedst i fig. 12. De to tætningsringe 117 og 119 holdes på plads af en støtte 121. Denne og bøsningen 123 har diametralt modsatte og på linie med hinanden liggende udløbsporte 125 og 127 mellem tætningsringene 117 og 119. Spindlen skal derfor kun roteres mindre end 45°, 35The FIG. 11 and 12 are similar to that of FIG. 7-9, except that two sealing rings are located diametrically opposite each other on either side of the spindle. The spindle 111, which has a stainless steel piston, is provided with a pair of diametrically opposite outlet ports 113 and 115, which is best seen in FIG. 12. The two sealing rings 117 and 119 are held in place by a support 121. This and the bushing 123 have diametrically opposite and aligned outlet ports 125 and 127 between the sealing rings 117 and 119. The spindle must therefore only be rotated less than 45 °, 35.

9 før en af portene vil være i det mindste delvist i flugt med en af bøsningens og støttens udløbsporte. I visse tilfælde findes der kun én udløbsport for bøsningen og tætningsstøtten i stedet for de viste to udløbsporte.9 before one of the gates will be at least partially in flight with one of the outlet gates of the bushing and support. In some cases, there is only one outlet port for the bushing and sealing support instead of the two outlet ports shown.

Fordelen ved den i fig. 11-12 viste konstruktion er, at der ikke udøves noget tværgående tryk på spindlen således som det kan være tilfældet ved de i fig. 1-10 viste konstruktioner. Et sådant tværtryk kan, efter at 10 spærreorganet har været i brug gennem en lang periode, forårsage stor slitage og utæthed. Det skal bemærkes, at de i fig. 11 og 12 viste to tætningsringe også kan anvendes i den i fig. 1-6 viste udførelsesform samt ved udførelsesformer, hvor spindlen har et stempel af metal.The advantage of the embodiment shown in FIG. 11-12 is that no transverse pressure is exerted on the spindle as may be the case in the FIG. 1-10. Such transverse pressure, after using the locking means for a long period of time, can cause great wear and leakage. It should be noted that in FIG. 11 and 12, two sealing rings shown in FIG. 1-6 and in embodiments wherein the spindle has a metal piston.

De i fig. 7-9 og 11-12 viste konstruktioner har den fordel, at tætningsringen 120 i størrelse og form er identisk med den på den ene side af spindlen anbragte lukkende tætningsring. Ved bevægelse af spindlen i forhold 20 til tætningsringen 120 vil eventuel slitage kun finde sted på dennes inderside. Den lukkende tætningsring slides imidlertid kun på den mod spindlen vendende, 90° i forhold til ringens 120 lukkeflade forskudte flade.The 7-9 and 11-12 have the advantage that the sealing ring 120 in size and shape is identical to the sealing ring disposed on one side of the spindle. When the spindle is moved relative to the sealing ring 120, any wear will only occur on the inside thereof. However, the closing sealing ring only wears on the spindle facing 90 ° relative to the shutter face of the ring 120.
Eftersom de to tætningsringe har samme størrelse og 25 form, kan de byttes om ved slitage og således være fuldt virksomme i den nye stilling. Spærreorganet kan således fungere længe uden udskiftning af tætninger.Since the two sealing rings have the same size and shape, they can be exchanged for wear and thus be fully effective in the new position. Thus, the locking member can operate for a long time without replacing seals.
Spindlen og bøsningen i de i fig. 7-12 viste konstruk-30 tioner er begge udformet med over for hinanden liggende skuldre, som hindrer udpresning af spindlen, og som tilvejebringer den beskrevne positionering af delene med henblik på sammenbygning. Ydermere findes ved alle udførelsesformede ifølge fig. 1-12 den tragtformede udvidel-35The spindle and bush in the FIG. 7-12 are both designed with opposite shoulders which prevent the spindle from being pressed out and which provide the described positioning of the parts for assembly. Furthermore, in all embodiments of FIG. 1-12 the funnel-shaped extension-35

Ved samling af spærreorganet ifølge opfindelsen er det nødvendigt, at de forskellige dele ligger helt på linie, 5 før kilen indsættes. Med dette for øje er bøsningen 144 udformet med et fremspring 155, der strækker sig ind i en rille 156 på den øvre ende af tætningsstøtten. Når tætningsstøtten føres over spindlen og bøsningen, vil fremspringet og rillen således sikre, at de forskellige 10 dele ligger fuldstændigt på linie, så at kilen kan indsættes. Dette bevirker samtidigt, at tætningsringen 140 altid vil blive korrekt monteret i forhold til udløbsportene for spindlen og tætningsunderstøtningen.When assembling the locking means according to the invention, it is necessary that the various parts are completely aligned before inserting the wedge. To this end, the sleeve 144 is formed with a projection 155 extending into a groove 156 on the upper end of the sealing support. As the sealing support is passed over the spindle and bushing, the protrusion and groove will ensure that the various 10 parts are completely aligned so that the wedge can be inserted. This also means that the sealing ring 140 will always be correctly mounted relative to the spindle outlet ports and the sealing support.
15 Den i fig. 13-15 viste konstruktion omfatter en indsats, der udgøres af en i det væsentlige cylindrisk bøsning 160, en indvendigt for denne anbragt tætningsstøtte 162 og en spindel 164. Spindlen er i det væsentlige den samme som den i fig. 7-10 viste og har et stålstempel 166 20 med et endeparti 168 med reduceret diameter til optagelse af en ring 170, som er anbragt mellem stemplet og støtten. Den vigtigste forskel mellem spindlen i fig. 7-10 og spindlen 164 er, at der findes et mellemliggende udadragende, rundtgående fremspring 172, som fastholder 25 spindlen i indsatsen i aksial retning.15 The embodiment of FIG. 13-15 comprise an insert comprised of a substantially cylindrical sleeve 160, an interior of said sealing support 162 and a spindle 164. The spindle is substantially the same as that of FIG. 7-10 and has a steel piston 166 20 having a reduced diameter end portion 168 for receiving a ring 170 disposed between the piston and the support. The main difference between the spindle of FIG. 7-10 and the spindle 164 is that there is an intermediate outwardly extending circumferential projection 172 which holds the spindle of the insert in the axial direction.
Som ved de andre udførelsesformer har bøsningen 160 ved den øvre del en udadragende rand 174 med et fremspring 176. Bøsningens udløbsport 178 har en i omkredsen udfor-30 met slids 180 og en tilstødende i det væsentlige cirkelformet åbning 182. Bøsningens 160 nedre ende har et par diametralt over for hinanden anbragte, nedadrettede låseområder 184, der er afgrænset på begge sider af smalle indhak 186. Åbninger 188 er udformet i en vis afstand 35As with the other embodiments, the sleeve 160 has a protruding rim 174 at the upper portion with a projection 176. The sleeve outlet port 178 has a circumferentially formed slot 180 and an adjacent substantially circular opening 182. The lower end of the sleeve 160 has a pair of diametrically opposed, downwardly locking areas 184, delimited on both sides by narrow notches 186. Apertures 188 are formed at a certain distance 35

11 fra låseområdernes 184 nedre ende og går i låsende indgreb med fremspring 190, der strækker sig udad fra tæt-ningsstøtningen 162 som vist i fig. 13.11 from the lower end of the locking regions 184 and engaging in locking engagement with projections 190 extending outward from the sealing support 162 as shown in FIG. 13th
5 Tætningsstøtten 162, der i det væsentlige er cylindrisk, er forsynet med en udløbsport, som består af en i omkredsen udformet slids 192 og en i det væsentlige cirkelformet åbning 194, hvilke flugter med henholdsvis bøsningens 160 slids 180 og åbning 182. Tætningsstøtten 10 162 er endvidere udformet med en cirkelformet åbning 196 til optagelse af en tætningsring 198, som fungerer på samme måde som tætningsringen 144 i fig. 1 og svarer til denne. Tætningsringen 198 er understøttet af stemplets 166 ydre flade 200 og bøsningens 160 indre flade 202 og 15 er således fastholdt mellem disse flader i åbningen 196 i tætningsstøtten.The sealing support 162, which is substantially cylindrical, is provided with an outlet port consisting of a circumferentially formed slot 192 and a substantially circular opening 194 which aligns with the slot 180 of the sleeve 160 and aperture 182. The sealing support 10 162 is further provided with a circular opening 196 for receiving a sealing ring 198 which functions in the same manner as the sealing ring 144 of FIG. 1 and corresponds to this one. The sealing ring 198 is supported by the outer surface 200 of the plunger 166 and the inner surface 202 and 15 of the sleeve 160 are thus retained between these surfaces in the opening 196 of the sealing support.
Tætningsstøttens 162 nedre ende er forsynet med hinanden krydsende ribber 204 og 206, som afgrænser gennemgangs-20 porte 208 for vandstrømning ind i spærreorganet. Et antal små fremspring 210 strækker sig udad fra ribberne 204 og 206 og hindrer, at indløbet lukkes af flade fremmedlegemer .The lower end of the sealing support 162 is provided with intersecting ribs 204 and 206 defining passage 20 ports 208 for water flow into the blocking means. A plurality of small projections 210 extend outwardly of the ribs 204 and 206 and prevent the inlet from being closed by flat foreign bodies.
25 Over den nedre ende har tætningsstøtten 162 en ringrille 212 til optagelse af en tætningsring 214. Ringrillen er på oversiden afgrænset af en diskontinuerlig krave 216.Above the lower end, the sealing support 162 has a ring groove 212 for receiving a sealing ring 214. The ring groove is bounded on the upper side by a discontinuous collar 216.
Denne har over for hinanden liggende udsparinger 218 til optagelse af bøsningens 160 låseområder 184.It has opposite recesses 218 for receiving the locking regions 184 of the sleeve 160.
30 Bøsningen 160 har en nedad vendende indvendig skulder 220, som samvirker med støttens 162 endeflade 222 til dannelse af en ringrille til optagelse af fremspringet 172 på spindlen 164, så at spindlen ikke kan bevæges i 35The sleeve 160 has a downwardly facing inner shoulder 220 which cooperates with the end surface 222 of the support 162 to form an annular groove for receiving the projection 172 on the spindle 164 so that the spindle cannot move within 35

12 aksial retning i bøsningen.12 axial direction in the bush.
Den i fig. 13-15 viste konstruktion er pålidelig og alligevel forholdsvis enkel at motere. Spindlen monteres i 5 tætningsstøtten, som derpå føres ind i bøsningens 160 nedre åbning. Spærreorganet fungerer på samme måde som i de andre beskrevne udførelsesformer.The FIG. 13-15 is reliable and yet relatively easy to operate. The spindle is mounted in the sealing support, which is then inserted into the lower opening of the sleeve 160. The locking means operates in the same manner as in the other embodiments described.
Spærreorganet i fig. 13-15 afviger fra de tidligere be-10 skrevne først og fremmest ved, at de relative stillinger mellem bøsningen og tætningsstøtten er vendt om. Kilen er erstattet af samvirkende låseorganer på tætningsstøtten og bøsningen. Ydermere har tætningsstøtten og bøsningen komplementære flader, som hindrer, at spindlen 15 kan bevæges aksialt.The locking means of FIG. 13-15 differs from those previously described above in that the relative positions between the sleeve and the sealing support are reversed. The wedge is replaced by cooperating locking means on the sealing support and bushing. Furthermore, the sealing support and bushing have complementary surfaces which prevent the spindle 15 from being axially movable.
