Description
780701484 fig. 1 visar slagapparaten L axiell sektion, fig. 2 i ett tvärsnitt längs linjen A-A i fig. 1 visar en utförings- form av stödorganen och fig. 3 i ett tvärsnitt längs linjen A-A i fig. 1 visar en annan ut- föringsformëv stödorganen. Fig. 1 shows the axial section of the percussion apparatus L, Fig. 2 in a cross-section along the line AA in Fig. 1 shows an embodiment of the support means and Fig. 3 in a cross-section along the line AA in Fig. 1 shows another embodiment support bodies.
I ett cylinderutrymme 12 i huset 1 finns en fram- och återgående slag- kolv 2. Huset 1 uppbär dessutom ett verktyg 4. Slagkolven 2 slår mot änden av verktyget 4. Ett spolrör 3 sträcker sig genom slagapparaten längs en borrning 15 i kolven 2 och spolrörets ena ände är inspänd i huset 1 och dess andra ände är införd i verktyget 4. En packning 5 är anordnad i verktygets 4 nacke för att leda spolvattnet till verk- tyget utan att det läcker in i slagmekanismen. Spolröret 3 är för- sett med stödorgan 11 och 14, som ligger an mot den inre ytan hos kolvens 2 borrning 15 och är placerade så, att kanaler 16 eller 17 bildas mellan dem för att leda luft samt av luft transporterat smörj- medel från utrymmet 7 till utrymmet 8 eller i mctsatt riktning. Ut- rymmena 7 och 8 vid slagkolvens 2 ändar står således i förbindelse med varandra genom den ringformiga passagen 6 och mellan stödorganen 11, 14 belägna kanaler 16, 17. Smörjluften matas in genom en kopp- ling 13 och en kanal 9 till utrymmet 7, och genom slagkolven 2 vida- re till utrymmet 8, varifrån den drivs till verktyget 4 för att smör- ja dettaÄ Från en koppling 10 leds spolvattnet genom spolröret 3 till verktyget 4.In a cylinder space 12 in the housing 1 there is a reciprocating percussion piston 2. The housing 1 also carries a tool 4. The percussion piston 2 strikes the end of the tool 4. A flushing tube 3 extends through the percussion device along a bore 15 in the piston 2 and one end of the flushing pipe is clamped in the housing 1 and its other end is inserted into the tool 4. A gasket 5 is arranged in the neck of the tool 4 to lead the flushing water to the tool without it leaking into the percussion mechanism. The flushing pipe 3 is provided with support means 11 and 14, which abut against the inner surface of the bore 15 of the piston 2 and are positioned so that channels 16 or 17 are formed between them to conduct air and lubricant transported by air from the space 7 to the space 8 or in the opposite direction. The spaces 7 and 8 at the ends of the percussion piston 2 are thus connected to each other through the annular passage 6 and channels 16, 17 located between the support members 11, 14. The lubricating air is fed in through a coupling 13 and a channel 9 to the space 7, and through the percussion piston 2 further to the space 8, from where it is driven to the tool 4 to lubricate it. From a coupling 10 the flushing water is led through the flushing pipe 3 to the tool 4.
