Description
Denne oppfinnelse vedrører en ventil, fortrinnsvis for anbringelse i tilførselsledningen for trykkluft til et hånd-verktøy, hvilken ventil er av den art som er angitt i den innledende del av etterfølgende patentkrav 1. This invention relates to a valve, preferably for placement in the supply line for compressed air to a hand tool, which valve is of the type specified in the introductory part of subsequent patent claim 1.
Ventiler av denne art benyttes til regulering og styring av drivmedier i form av trykkluft og -væske som benyttes i hen-holdvis pneumatiske og hydrauliske motorer av forskjellig art. Valves of this type are used for regulation and control of drive media in the form of compressed air and liquid which are used in pneumatic and hydraulic motors of different types respectively.
Slike motorer skal betjenes på en hensiktsmessig og sikker måte, og ventilen skal derfor kunne innstilles av brukeren på en bekvem måte avhengig av den aktuelle betjeningssitu-asjon. Such motors must be operated in an appropriate and safe manner, and the valve must therefore be able to be set by the user in a convenient manner depending on the relevant operating situation.
I forbindelse med håndverktøy skal motoren således kunne betjenes med fingrene og helst uten at dette forringer kontrollen av verktøyet, da det ellers kan skje skader på verk-tøy og/eller emne. In connection with hand tools, the motor must thus be able to be operated with the fingers and preferably without this impairing the control of the tool, as otherwise damage to the tool and/or workpiece may occur.
I praksis volder dette særlig problemer ved større og tyngre håndverktøy som stiller så store krav til et sikkert hånd-grep at reguleringen av drivmediet gjennom ventilen vanske-lig kan foretas uten at det går ut over kontrollen av verk-tøyet. Dette betyr at verktøyet må fjernes fra arbeidsstedet, det vil si gjøres ikke-bearbeidende, dersom en endring av motorens omdreiningshastighet skal reguleres av ventilen, hvoretter verktøyet igjen kan gjøres bearbeidende ved å bringe det tilbake til arbeidsstedet. In practice, this causes particular problems with larger and heavier hand tools that place such high demands on a secure hand grip that the regulation of the drive medium through the valve can be carried out with difficulty without affecting the control of the tool. This means that the tool must be removed from the workplace, i.e. made non-working, if a change in the engine speed is to be regulated by the valve, after which the tool can again be made working by bringing it back to the working place.
Fra US-PS 841.322, 903.451, 904.134 og 2.125.554 er det kjent ventiler hvor en ventilspindel er montert på en med utvendige gjenger forsynt bøssing som kan beveges ved hjelp av et organ med tilsvarende innvendige gjenger. From US-PS 841,322, 903,451, 904,134 and 2,125,554 valves are known where a valve spindle is mounted on a bushing provided with external threads which can be moved by means of a body with corresponding internal threads.
Ved den i US-PS 841.322 beskrevne ventil er bøssingen ved sine ender tettet mot ventilhusets ytre flate. Bøssingen er ved hjelp av en skrue forbundet med et i ventilhusets indre aksialt forskyvbart ventillegeme, idet skruen trenger igjen-nom en skrått forløpende utsparing i ventilhuset på en slik måte at en dreining av bøssingen medfører en aksial for-skyvning av ventiUegemet i ventilhuset for åpning eller stengning av gjennomstrømningen. Åpningen og stengningen av ventilen skjer således ved at den ytre bøssing dreies omkring ventilhuset, slik at skruen beveger seg i utsparingen, hvorved ventiUegemet forskyves i forhold til ventilsetet. Når ventilen så er åpen, må bøssingen ved ytre påvirkning dreies til den stengte stilling for at ventilen skal sten-ges . In the case of the valve described in US-PS 841,322, the bushing is sealed at its ends against the outer surface of the valve housing. By means of a screw, the bushing is connected to an axially displaceable valve body inside the valve housing, the screw again penetrating an obliquely extending recess in the valve housing in such a way that turning the bushing results in an axial displacement of the valve body in the valve housing for opening or closure of the flow. The opening and closing of the valve thus takes place by turning the outer sleeve around the valve housing, so that the screw moves in the recess, whereby the valve body is displaced in relation to the valve seat. When the valve is then open, the sleeve must be turned to the closed position by external influence in order for the valve to be closed.
Den i US-PS 903.451 beskrevne ventil er gjort selvlukkende ved at bøssingen ved dreining av nevnte organ presser en fjær sammen, slik at den kan lukke ventilen når den slippes. For bedre å kunne betjene ventilen er den forsynt med et utragende håndtak. En slik fjær er imidlertid et sårbart element i en ventil, da fjæren kan knekke eller slakkes, slik at lukkingen av ventilen ikke skjer sikkert. Dette er især ved håndslipeverktøy en betydelig ulempe og vil i uheldigste tilfelle utgjøre en fare for brukeren dersom tilførselen av drivmediet til motoren ikke hurtig avbrytes når håndtaket slippes. The valve described in US-PS 903,451 is made self-closing by the fact that the bushing, when rotating the said member, presses a spring together, so that it can close the valve when it is released. In order to be able to operate the valve better, it is equipped with a protruding handle. However, such a spring is a vulnerable element in a valve, as the spring can break or loosen, so that the closing of the valve does not take place securely. This is a significant disadvantage, especially with hand grinding tools, and will in the worst case pose a danger to the user if the supply of the drive medium to the motor is not quickly interrupted when the handle is released.
Det er oppfinnelsens formål å lette betjeningen og dermed øke arbeidssikkerheten samt forbedre presisjonen til et med en ventil av angjeldende art utstyrt verktøy, og dette oppnås ved hjelp av en ventil som er utformet i overensstemmel-se med den karakteriserende del av etterfølgende patentkrav 1. The purpose of the invention is to facilitate operation and thereby increase work safety as well as improve the precision of a tool equipped with a valve of the type in question, and this is achieved by means of a valve which is designed in accordance with the characterizing part of subsequent patent claim 1.
Herved oppnås en ventil som kan utformes i et håndtak som kan utgjøre det ene holdegrep på et verktøy, idet drivmediet kan ledes til håndtakets bakside ved husets lukkede ende, for eksempel gjennom en slange, og ledes gjennom ventilen til åpningen i bøssingen, hvorfra det for eksempel gjennom et rør ledes til arbeidsmotoren. Dette rør utgjør en håndtaksdel som er en del av verktøyet, slik at styre-og reguleringsfunksjonen kan skje ved hjelp av det ene håndtak med en innbygget reguleringsventil. Betjeningen av ventilen skjer ved en aksial bevegelse av ventilhuset, hvilket ikke krever store krefter eller at hendene flyttes fra håndtaket på et verktøy hvor ventilen er montert. Det er heller ikke nødvendig å overvinne en fjærkraft ved åpningen for å oppnå en selvlukkende ventil, hvorved ventilen blir lettere å betjene enn de kjente ventiler, idet trykket i ventilen på grunn av dennes geometri automatisk vil lukke denne når håndtaket slippes. This results in a valve that can be designed into a handle that can form the one holding handle on a tool, as the drive medium can be led to the back of the handle at the closed end of the housing, for example through a hose, and led through the valve to the opening in the bushing, from where it is for example through a pipe is led to the work engine. This tube forms a handle part which is part of the tool, so that the control and regulation function can be carried out with the help of one handle with a built-in regulation valve. The valve is operated by an axial movement of the valve housing, which does not require great effort or that the hands are moved from the handle of a tool where the valve is mounted. It is also not necessary to overcome a spring force at the opening to achieve a self-closing valve, whereby the valve becomes easier to operate than the known valves, as the pressure in the valve due to its geometry will automatically close it when the handle is released.
Ved å utforme ventilen som angitt i patentkrav 2, kan den bygges opp av enkeltkomponenter som dels er billige å pro-dusere, idet de kan fremstilles ved enkle arbeidsoperasjoner som boring og dreiing, og dels lar seg skifte ut på en enkel måte . By designing the valve as stated in patent claim 2, it can be built up from individual components which are partly cheap to produce, as they can be produced by simple work operations such as drilling and turning, and partly can be replaced in a simple way.
Oppfinnelsen vil i det etterfølgende bli nærmere forklart under henvisning til tegningene, hvor: Fig. 1 i snitt etter linjen I-l i fig. 3 viser ventilen i stengt stilling; Fig. 2 viser samme ventil i åpen stilling i et til fig. 1 svarende snitt; The invention will subsequently be explained in more detail with reference to the drawings, where: Fig. 1 in section along the line I-1 in fig. 3 shows the valve in the closed position; Fig. 2 shows the same valve in the open position in a further fig. 1 corresponding cut;
Fig. 3 viser ventilen ifølge fig. 1 og 2 i sideriss. Fig. 3 shows the valve according to fig. 1 and 2 in side view.
På tegningene er vist et utførelseseksempel av oppfinnelsen hvor ventilen inngår som en del av betjeningshåndtaket 5 av en ikke vist motordrevet slipemaskin. Maskinen er forsynt med et betjeningshåndtak, hvis ene ende på tegningene er re-presentert ved røret 5 som kan utgjøre enden av den høyre eller venstre del av nevnte betjeningshåndtak. The drawings show an embodiment of the invention where the valve is included as part of the operating handle 5 of a not shown motor-driven grinding machine. The machine is provided with an operating handle, one end of which in the drawings is represented by the tube 5 which can form the end of the right or left part of said operating handle.
Drivmediet i form av trykkluft eller -væske tilføres motoren gjennom en slange 13 som er tilkoplet ventilen via en slan-genippel 12 av hensiktsmessig utforming. The propellant in the form of compressed air or liquid is supplied to the engine through a hose 13 which is connected to the valve via a suitably designed hose nipple 12.
Selve ventilen består av et hus 1 som kan dreies omkring lengdeaksen, og som ytterst kan være overtrukket med gummi 16 for å forbedre komforten og sikre et godt grep. The valve itself consists of a housing 1 which can be rotated around the longitudinal axis, and which can be coated on the outside with rubber 16 to improve comfort and ensure a good grip.
Ventilhuset 1 er lukket ved den ene ende slik at det dannes et innløpskammer 11 ved slangenippelen 12. I husets endevegg er det skrudd inn en bolt 10, som dels bærer en skålformet ring 7 og dels et avstandsrør 8 som fikserer ringen 7 i en gitt avstand fra husets ende. The valve housing 1 is closed at one end so that an inlet chamber 11 is formed at the hose nipple 12. A bolt 10 is screwed into the end wall of the housing, which partly carries a bowl-shaped ring 7 and partly a distance tube 8 which fixes the ring 7 at a given distance from the end of the house.
Videre er det i huset anordnet et skrått forløpende gjen-nomgående spor 4, se særlig fig. 3. I dette spor kan en tapp 3 forskyves, slik at en dreining av huset gir en aksial bevegelse av dette i forhold til en stasjonær bøssing 2. Furthermore, there is arranged in the housing an obliquely extending through track 4, see in particular fig. 3. In this groove, a pin 3 can be displaced, so that a rotation of the housing causes an axial movement of it in relation to a stationary bushing 2.
Denne bøssing 2 er skjøvet inn i huset 1, slik at den rager et passende stykke inn i huset. Ved enden er bøssingen 2 forsynt med et rundtgående spor, hvori det er anbrakt en pakning 6 som gir tetting mellom bøssing og hus. This bushing 2 is pushed into the housing 1, so that it protrudes a suitable distance into the housing. At the end, the bushing 2 is provided with a circumferential groove, in which is placed a gasket 6 which provides a seal between the bushing and the housing.
Et stykke herfra er bøssingen forsynt med en flens som på sin utadvendte flate, som forløper vinkelrett på aksen, danner et ventilsete 14. I denne flens er videre inn-skrudd tappen 3 som holder huset på plass. Some distance from here, the bushing is provided with a flange which on its outward facing surface, which runs perpendicular to the axis, forms a valve seat 14. Into this flange is also screwed the pin 3 which holds the housing in place.
Endelig er bøssingen 2 ved sin utragende ende forsynt med utvendige gjenger som kan skrues inn i røret 5 og hvorigjen-nom drivmediet ledes under drift. Finally, the bushing 2 is provided at its protruding end with external threads which can be screwed into the pipe 5 and through which the drive medium is led during operation.
Som det fremgår av tegningene, monteres ventilen med en pakning 9 mellom ringen 7 og avstandsrøret 8 slik at ventilen i den stilling som er vist i fig. 1, helt har stengt for drivmedium til motoren. As can be seen from the drawings, the valve is mounted with a gasket 9 between the ring 7 and the spacer tube 8 so that the valve in the position shown in fig. 1, has completely shut off the drive medium to the engine.
Ved dreining av håndtaket 16 mot den i fig. 2 viste posisjon, beveges huset mot venstre og dermed ventiUegemet 7, 8, 9, 10 bort fra setet 14. Dette gir passasje for mediet gjennom ventilen. Passasjen kan innstilles trinnløst fra stengt til maksimalt åpen, hvorved man oppnår mulighet for en presis styring av drivmediet til motoren. When turning the handle 16 towards the one in fig. 2 shown position, the housing is moved to the left and thus the valve body 7, 8, 9, 10 away from the seat 14. This provides passage for the medium through the valve. The passage can be adjusted steplessly from closed to maximally open, whereby the possibility of precise control of the drive medium for the engine is achieved.
Når håndgrepet slippes, vil huset ved hjelp av drivmediets trykk på endeflaten, som er større enn bøssingens endeflate, bevege huset mot høyre og dermed ventiUegemet mot ventilsetet, slik at ventilen lukkes. Det dreier seg således om en selvlukkende ventil, som er helt uavhengig av trykkfjærer eller lignende. When the handle is released, the housing will, with the help of the driving medium's pressure on the end surface, which is greater than the bushing's end surface, move the housing to the right and thus the valve body towards the valve seat, so that the valve closes. It is thus a self-closing valve, which is completely independent of compression springs or the like.
Dette innebærer en betydelig sikkerhet, idet motoren automatisk og helt pålitelig vil avbryte trykkmediumtilførselen til motoren som derved vil stoppe. Ved et fall eller annet uhell vil håndgrepet bli sluppet og motoren dermed stoppet. This implies considerable safety, as the motor will automatically and completely reliably interrupt the pressure medium supply to the motor, which will thereby stop. In the event of a fall or other accident, the handle will be released and the engine will thus stop.
Det kan sammenfatningsvis fastslås at denne enkle og drifts-sikre ventil gir en trinnløst variabel regulering av motorens effekt samtidig som man bevarer full kontroll av verk-tøyet under bruken. Hertil kommer den nevnte sikkerhet for øyeblikkelig stopp av motoren dersom grepet omkring håndtaket skulle opphøre. In summary, it can be stated that this simple and reliable valve provides steplessly variable regulation of the motor's power while maintaining full control of the tool during use. In addition, there is the aforementioned security for immediate stopping of the motor if the grip around the handle should cease.
