Opfindelsen angår en ventil, fortrinsvis til anbringelse i 5 tilførselsledningen for trykluft til et håndværktøj, og omfattende et forskydeligt ventillegeme, som kan ligge an mod et ventilsæde og afgrænse gennemstrømningen af et medie, hvilken ventil har et ventilhus med en endevæg og med tilgang for mediet ved endevæggen, og hvor der indvendigt 10 fra denne ende udgår en spindel med et ventillegeme.The invention relates to a valve, preferably for placement in the compressed air supply line for a hand tool, and comprising a displaceable valve body which can abut against a valve seat and define the flow of a medium, which valve has an valve housing with an end wall and with access to the medium. at the end wall, and from which an interior 10 from this end exits a spindle with a valve body.

Ventiler af denne art anvendes til regulering og styring af drivmidler i form af komprimeret luft og væske, som benyttes i henholdsvis luft- og hydraulikmotorer af forskel-15 lig art.Valves of this kind are used for the control and control of propellants in the form of compressed air and liquid, which are used in air and hydraulic motors of various kinds, respectively.

Sådanne motorer skal betjenes på en hensigtsmæssig og sikker måde, hvorfor ventilen skal kunne indstilles af brugeren på en bekvem måde i afhængighed af den aktuelle betje-20 ningssituation.Such motors must be operated in an appropriate and safe manner, so that the valve must be able to be adjusted by the user in a convenient manner depending on the current operating situation.

Ved håndværktøjer skal motoren således kunne betjenes med fingrene, og helst uden at det forringer kontrollen med værktøjet, idet der ellers kan ske skader på værktøj og/-25 eller emne.In the case of hand tools, the motor must thus be able to be operated with the fingers, and preferably without impairing the control of the tool, otherwise damage to the tool and / -25 or workpiece may occur.

I praksis volder det især problemer ved større og tungere håndværktøjer, der stiller så store krav til et sikkert håndgreb, at reguleringen af drivmidlet gennem ventilen 30 vanskeligt kan foretages, uden at det går ud over kontrollen med værktøjet. Dette betyder, at værktøjet må fjernes fra arbejdsstedet, det vil sige gøres ikke-bearbejdende, dersom en ændring af motorens omdrejningshastighed skal reguleres af ventilen, hvorefter værktøjet atter kan gøresIn practice, it is especially problematic for larger and heavier hand tools that place such demands on a safe grip that the control of the propellant through the valve 30 can be difficult to make without compromising the control of the tool. This means that the tool must be removed from the work site, that is, rendered non-machining if a change in engine speed must be regulated by the valve, after which the tool can be made again.

bearbejdende ved at nærme dette til arbejdsstedet.working by approaching this to the workplace.

Fra US patentskrifterne nr. 903.451, nr. 904.134 og nr. 2.125.554 kendes ventiler, hvor en ventilspindel er monte-5 ret på en med udvendigt gevind forsynet bøsning, der kan bevæges ved hjælp af en omløber med tilsvarende indvendigt gevind. Den i US patentskrift nr. 903.451 beskrevne ventil er gjort selvlukkende ved, at bøsningen ved drejning af omløberen presser en fjeder sammen, så den kan lukke ven-10 tilen, når denne slippes. For bedre at kunne betjene ventilen er den forsynet med et udragende håndtag. En fjeder er imidlertid en sårbar ting i en ventil, da den kan knække eller slappes, så lukningen af ventilen ikke sker sikkert. Dette er især ved et håndværktøj med slibemidler en 15 betydelig ulempe og vil i uheldigste tilfælde udgøre en fare for brugeren, dersom tilledningen af drivmediet til motoren ikke hurtigt afbrydes, når håndtaget slippes.From US Patent Nos. 903,451, No. 904,134 and No. 2,125,554, valves are known in which a valve spindle is mounted on an outer threaded sleeve which can be moved by means of a screwdriver with corresponding internal thread. The valve disclosed in U.S. Patent No. 903,451 is made self-closing in that the sleeve, when rotating the sheath, compresses a spring so that it can close the valve when released. In order to better operate the valve, it is equipped with a protruding handle. However, a spring is a vulnerable thing in a valve as it can break or be released so that the closing of the valve does not happen safely. This is especially a significant disadvantage of a hand tool with abrasives, and in the unfortunate case it will pose a danger to the user if the supply of the propellant to the motor is not interrupted quickly when the handle is released.

Det er opfindelsens formål at lette betjeningen og øge ar-20 bejdssikkerheden samt forbedre præcisionen af værktøjer med de ovenfor anførte kendte ventiler, og dette opnås ved hjælp af en ventil af den indledningsvist angivne art, hvilken ventil ifølge opfindelsen er særegen ved, at ventilsædet vender mod husets ende og er indrettet til at 25 kunne samvirke med et ventillegeme med en sædeflade, som er udformet som en reces i en bøsning, der er tætnet i forhold til ventilhuset og lejret aksialt forskydeligt i forhold til spindelen, og hvor bøsningen ved den bort fra husets lukkede ende vendende ende er fastgjort til en til-30 gangsslange eller -rør for mediet.It is an object of the invention to facilitate operation and increase job security as well as to improve the precision of tools with the above-mentioned known valves, and this is achieved by means of a valve of the aforementioned kind, which valve according to the invention is peculiar in that the valve seat turns towards the end of the housing and is adapted to cooperate with a valve body with a seat surface, which is designed as a recess in a bushing which is sealed relative to the valve housing and is axially displaceable relative to the spindle, and where the bushing extends therefrom. from the closed end of the housing is attached to a supply hose or tube for the medium.

Herved fås en ventil, som kan udformes i et håndgreb, der kan udgøre det ene holdegreb på et værktøj, idet mediet kan ledes til håndtagets bagside ved husets lukkede ende,Hereby is provided a valve which can be formed in a handle which may constitute one holding handle of a tool, the medium being directed to the rear of the handle at the closed end of the housing,

for eksempel gennem en slange, og ledes gennem ventilen til åbningen i bøsningen og fra det for eksempel gennem et rør ledes til arbe j dsmotoren. Dette rør udgør et styr og er en del af værktøjet, så styre- og reguleringsfunktionen 5 kan ske ved hjælp af det ene håndgreb med en indbygget reguleringsventil. Betjeningen af ventilen sker ved en aksi-al bevægelse af ventilhuset, hvilket ikke kræver store kræfter, eller at hænderne flyttes fra håndtaget på et værktøj, hvor ventilen er monteret. Det er heller ikke 10 nødvendigt at overvinde en fjederkraft ved åbningen for at opnå en selvlukkende ventil, hvorved ventilen bliver lettere at betjene end de kendte, idet trykket i ventilen på grund af dennes geometri automatisk vil lukke denne, når håndtaget slippes.for example, through a hose, and is passed through the valve to the opening in the sleeve and from it, for example, through a tube, to the working motor. This pipe forms a guide and is part of the tool, so that the control and control function 5 can be effected by means of one handle with a built-in control valve. The valve is operated by an axial movement of the valve body, which does not require large forces or the hands are moved from the handle of a tool on which the valve is mounted. Also, it is not necessary to overcome a spring force at the opening to obtain a self-closing valve, whereby the valve becomes easier to operate than the known ones, the pressure of the valve, due to its geometry, will automatically close it when the handle is released.

Ved at udforme ventilhuset, som omhandlet i krav 2, forstærkes ventilens selvlukkende funktion, fordi man ved forskellen mellem arealerne udnytter trykket fra mediet til at lukke ventilen. Dette giver en stor betjeningskom-20 fort og samtidig en stor sikkerhed for lukning af ventilen ved blot at slippe håndtaget.By designing the valve housing as claimed in claim 2, the self-closing function of the valve is enhanced because by the difference between the areas the pressure from the medium is used to close the valve. This provides a large operating comfort and at the same time a great security for closing the valve by simply releasing the handle.

Ved at gøre huset drejeligt, som omhandlet i krav 3, og at forsyne huset med et skråt spor og lade en stift glide i 25 sporet, kan man forskyde huset aksialt i forhold til bøsningen ved drejning af huset, og regulering af ventilen vil kunne ske ved en lille drejning af huset, medens man stadig har greb om værktøjet.By making the housing rotatable as claimed in claim 3, and providing the housing with an inclined groove and sliding a pin into the groove, the housing can be displaced axially with respect to the sleeve when turning the housing, and the valve can be adjusted at a slight turn of the house while still grasping the tool.

30 Ved at udforme ventilen, som omhandlet i krav 4, kan den opbygges af enkelte komponenter, der dels er forholdsvis billige at producere, idet de kan fremstilles ved simple operationer som boring og drejning, og dels lader sig udskifte på en enkel måde.By designing the valve as claimed in claim 4, it can be built up of individual components which are both relatively inexpensive to produce as they can be manufactured by simple operations such as drilling and turning, and partly can be replaced in a simple manner.

Ventilen ifølge opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, hvor: 5 Fig. 1 viser et snitbillede af ventilen ifølge opfindelsen i dens lukkede position, set i retningen I-I på fig. 3, fig. 2 viser den samme ventil, men i åben position, og 10 fig, 3 viser ventilen set i perspektiv.The valve according to the invention will now be described in more detail with reference to the drawing, in which: 1 shows a sectional view of the valve according to the invention in its closed position, seen in the direction I-I in FIG. 3, FIG. 2 shows the same valve, but in the open position, and 10 fig. 3 shows the valve in perspective.

På tegningen er vist en udførelsesform for ventilen, hvor denne indgår som en del af manøvrehåndtaget eller styret 5 15 til en ikke vist motordrevet slibemaskine. Maskinen er forsynet med et styr, hvis ene ende er vist på tegningen som røret 5, der er enden af den højre eller venstre part af stirret.In the drawing, an embodiment of the valve is shown in which it is included as part of the maneuver handle or guided 5 15 for a motor grinding machine not shown. The machine is provided with a guide, one end of which is shown in the drawing as the tube 5, which is the end of the right or left part of the stare.

20 Drivmidlet i form af trykluft eller væske tilledes motoren gennem en slange 13, der er sluttet til ventilen via en slangekobling 12, som kan være af enhver egnet art.The propellant in the form of compressed air or liquid is fed to the motor through a hose 13 connected to the valve via a hose coupling 12, which may be of any suitable kind.

Selve ventilen består af et hus 1, der kan drejes omkring 25 dets længdeakse, hvilket hus yderst kan være overtrukket med gummi 16 for at forbedre komforten og sikre grebet.The valve itself consists of a housing 1 which can be rotated about its longitudinal axis, which housing can be extremely coated with rubber 16 to improve comfort and ensure grip.

Huset 1 er lukket med en endevæg ved den ene ende, så der dannes et indløbskammer 11 ved slangekoblingen 12. I hu-30 sets endevæg er der iskruet en bolt 10, som fastholder dels en skålformet ringpart 7 og dels et afstandsrør 8, som fastholder ringparten 7 i en given afstand fra husets endevæg.The housing 1 is closed with an end wall at one end so that an inlet chamber 11 is formed at the hose coupling 12. In the end wall of the housing there is screwed a bolt 10 which retains partly a bowl-shaped ring part 7 and partly a spacer 8 which retains ring portion 7 at a given distance from the end wall of the housing.

5 DK 157826 B5 DK 157826 B

Endvidere er der i husets væg udformet et gennemgående spor 4, hvis længdeakse danner en vinkel v med et plan vinkelret på husets 1 længdeakse, se især fig. 3. I dette spor kan en tap i form af et bolthoved 3 forskydes, så en 5 drejning af huset giver en aksial bevægelse af dette i forhold til en stationær bøsning 2 på enden af røret 5.In addition, a through groove 4 is formed in the wall of the housing, the longitudinal axis of which forms an angle v with a plane perpendicular to the longitudinal axis of the housing 1, see in particular fig. 3. In this groove, a pin in the form of a bolt head 3 can be displaced so that a rotation of the housing causes an axial movement thereof relative to a stationary bushing 2 on the end of the tube 5.

Denne bøsning 2 er indskudt i huset, så den rager et passende stykke ind i huset 1, og bøsningen er ved den i hu- 10 set indre ende forsynet med et rundtgående spor, hvori en pakning 6 er anbragt, som giver tætning mellem bøsning og hus.This sleeve 2 is inserted into the housing so that it protrudes an appropriate portion into the housing 1, and the sleeve is provided at the inner end of the housing with a circumferential groove in which a gasket 6 is provided which provides a seal between the sleeve and the housing. House.

Et stykke herfra er bøsningens boring forsynet med en re- 15 ces, der med dens udadvendende flade, der forløber vinkelret på aksen, danner sæde 14 i ventilen. I denne reces er endvidere indskruet den bolt med et hoved 3, som holder huset på plads.A part of this is the bore of the bushing provided with a recess which, with its outward facing surface extending perpendicular to the axis, forms seat 14 in the valve. In this recess is also screwed in the bolt with a head 3, which holds the housing in place.

20 Endelig er bøsningen 2 ved dens udragende ende forsynet med et udvendigt gevind, som anvendes til at forbinde bøsningen med enden af røret 5, og hvorigennem drivmidlet ved drift ledes til.Finally, the bushing 2 is provided at its protruding end with an external thread, which is used to connect the bushing to the end of the pipe 5, through which the propellant in operation is guided.

25 Som det fremgår af tegningen, samles ventilen med en pakning 9 mellem ringen 7 og røret 8, så ventilen i den i fig. 1 viste stilling helt har afskåret for drivmidlet til motoren.25 As shown in the drawing, the valve is assembled with a gasket 9 between the ring 7 and the tube 8, so that the valve in the embodiment shown in FIG. 1 has completely cut off the engine propellant.

30 Ved drejning af håndtaget 16 hen imod den i fig. 2 viste position bevæges huset mod venstre og dermed ventillegemet 7, 8, 9 bort fra sædet 14. Dette giver passage for mediet gennem ventilen. Passagen kan indstilles trinløst fra afspærring til maksimum, hvorved man opnår mulighed for en30 By turning the handle 16 towards the one shown in FIG. 2, the housing is moved to the left and thus the valve body 7, 8, 9 away from the seat 14. This provides passage for the medium through the valve. The passage can be set infinitely from lock-up to maximum, thus allowing one

6 præcis styring af drivmediet til motoren.6 precise control of the motor drive medium.

Når håndgrebet slippes, vil huset ved hjælp af drivmediets tryk på endevæggen, hvis areal er større end bøsningens 5 endeareal, bevæges huset mod højre og derved ventillegemet mod ventilsædet, der herved lukker ventilen. Der er således tale om en selvlukkende ventil, der er helt uafhængig af trykfjedre.When the handle is released, by means of the pressure medium on the end wall, the area of which is greater than the end area of the bushing 5, the housing is moved to the right and thereby the valve body towards the valve seat, thereby closing the valve. It is thus a self-closing valve which is completely independent of compression springs.

10 Dette betyder en væsentlig sikkerhed, idet motoren automatisk og helt pålideligt vil afbryde trykmedietilførslen til motoren, der dermed vil stoppe. Ved et fald eller andet uheld vil håndgrebet uvilkårligt blive sluppet og motoren dermed stoppet.10 This means a significant safety, as the engine will automatically and reliably interrupt the pressure medium supply to the engine, which will thereby stop. In the event of a fall or other accident, the handle will be released unconditionally, thus stopping the engine.

1515

Sammenfattende kan det fastslås, at denne simple og driftssikre ventil giver en trinløs variabel regulering af motorens effekt samtidig med, at man bevarer fuld kontrol med værktøjet under driften. Hertil kommer den nævnte sik-20 kerhed for øjeblikkeligt stop af motoren, dersom grebet omkring håndtaget skulle ophøre.In summary, it can be stated that this simple and reliable valve provides an infinitely variable control of the engine power while maintaining full control of the tool during operation. In addition, the said safety for immediate stopping of the engine should the grip around the handle cease.
