451 236 2 Efter ventilen följer en konisk förlängningshylsa 15 helt eller delvis utförd i gummi eller annat elastiskt material inneslutande en cylindrisk kammare 16. I denna kammare, som åtskiljer ventilen från verktygets utblåsnings- eller slutmunstycke 17 erhålls en tryckstabiliserad zon. Efter kammaren 16 följer utblåsnings- eller slutmunstycket 17. Reglerar- mens 12 ände har en tapp som går in i ett hål 18 i detta. Vid ett manuellt, sidoriktat tryck på förlängningshylsan 15 snedställs ventilkäglan 13 så att mindre eller större partiell öppning av ventilen erhålls. Slutmunstycket 17 är cirkulärcylindriskt och har nära periferien en serie ringsformigt anordnade, cylindriska kanaler 30. För att förhindra direkt hudkontakt med utloppskanalerna 30 förefinns vid slutmunstycket 17 ett eller flera från ândplanet 33 utskjutande avståndsorgan. Deras längd M vilken är väsentlig och minst 1,2 ggr, företrädesvis 2 ggr diame- tern för respektive utloppskanal 30 kan vara placerade mellan de ringformigt placerade utloppskanalerna 30 eller såsom en enda utskjutande tapp 41 anordnad centralt på ytan 33 omgivet av utloppsöppningarna 30, såsom visas i fig. 2 och 3. Utformningen av nämnda avståndsorgan är sådan att medejekteringen ej väsent- ligen hämmas eller att ljudnivån vid utloppet ökar. Patentkrav451 236 2 The valve is followed by a conical extension sleeve 15 made entirely or partly of rubber or other elastic material enclosing a cylindrical chamber 16. In this chamber, which separates the valve from the blow-out or end nozzle 17 of the tool, a pressure-stabilized zone is obtained. The chamber 16 is followed by the exhaust or end nozzle 17. The end of the regulator 12 has a pin which enters a hole 18 therein. At a manual, lateral pressure on the extension sleeve 15, the valve cone 13 is tilted so that a smaller or larger partial opening of the valve is obtained. The end nozzle 17 is circular-cylindrical and has near the periphery a series of annular, cylindrical channels 30. To prevent direct skin contact with the outlet channels 30, one or more spacers projecting from the end plane 33 are provided at the end nozzle 17. Their length M which is substantial and at least 1.2 times, preferably 2 times the diameter of the respective outlet duct 30 can be placed between the annularly placed outlet ducts 30 or as a single projecting pin 41 arranged centrally on the surface 33 surrounded by the outlet openings 30, such as is shown in Figs. 2 and 3. The design of said spacer means is such that the co-injection is not substantially inhibited or that the sound level at the outlet increases. Patent claims 1. Blåsanordning med en anslutning (8) för mottagande av en trycksatt, gasformig fluid, och ett utblåsningsmunstycke (17) för avgivande av nämnda fluid genom ett antal utblåsningskanaler (30), som är anordnade i en ändyta på munstycket, k ä n n e t e c k n a d av en från nämnda ändyta centralt utskjutande tapp (41) till försvårande av direkt hudkontakt mellan operatören och munstyckets ändyta, varvid tappen är utformad för att medge väsentligen opåverkad, av utblåst tryckfluidum alstrad medejektering av omgivande medium och varvid nämnda utblåsningskanaler (30) är ringformigt placerade kring nämnda tapp.Blowing device with a connection (8) for receiving a pressurized, gaseous fluid, and a blow-out nozzle (17) for discharging said fluid through a number of blow-out channels (30), which are arranged in an end surface of the nozzle, characterized by a pin (41) projecting centrally from said end face to impede direct skin contact between the operator and the end face of the nozzle, the pin being designed to allow substantially unaffected, blown pressure fluid generated co-injection of ambient medium and said blow-out channels (30) being annularly positioned said pin. 2. Blåsanordning enligt krav 1, k ä n n e t e c k n a d av att tappens (41) längd är minst 1,2 gånger, företrädesvis minst 2 gånger så stor som utblåsningskanalernas (30) diameter.
