CLASS E 21 c PATENTARY TIME FROM 25 NOVEMBER 1954 GRANTED ON 18 JANUARY '1962 PUBLISHED ON 20 MARCH 1962 Ans. The present invention relates to a device for internal combustion engine-driven rock drilling machines, with the engine housing at the top composed of three main parts, namely a crankcase part and a crankcase part. handle part, wherein the two first-mentioned parts stand against each other at an angle perpendicular to the motor shaft. The main feature of the invention is that the latter part abuts one or the other of the former according to a plane perpendicular to the said plane, and that the standing plane between the handle part and the crankcase part resp. the crane tank section extends along or through cavities, containing intake valves for air or fuel air mixture to the internal combustion engine, so that these valves are made accessible by the removal of the landing gear section. By means of this device it is achieved, among other things, that the suction valves are made easily accessible, in that it is only required that the handle part be removed. Furthermore, a simple construction with small outer dimensions is possible. In addition, the mounting of the crankcase mechanism and the fuel tank is facilitated.

Ett exempel pS. uppfinningens tillampning visas pa ritningen, dar fig. 1 visar den huvudsakliga delen av en forbranningsmotordriven bergborrmaskin i stort sett i axialsektion, fig. 2 visar samma maskin delvis skuren efter ett plan, vinkelratt mot det i fig. 1 visade, och fig. 3 visar en vy av handtagsdelen sedd underifran, dvs. efter linjen A—A i fig. 2. An example pS. the application of the invention is shown in the drawing, where Fig. 1 shows the main part of an internal combustion engine driven rock drilling machine substantially in axial section, Fig. 2 shows the same machine partly cut after a plane, perpendicular to that shown in Fig. 1, and Fig. 3 shows a view of the handle part seen from below, ie. along the line A — A in Fig. 2.

Sasom ritningen visar, Sr bergborrmaskinens holje upptill uppdelat i tre huvuddelar, namligen en vevhusdel 1, en. bransletankdel 2 och en handtagsdel 3. Stodplanet (vid 4) mellan vevhusdelen och bransletankdelen stracker sig vinkelratt mot m.otorns vevaxel och handtagsdelen 3 stoder mot vevhusdelen 1 och bransletankdelen 2 efter ett plan som Sr parallellt med vevaxeln 5. Stodplanet 6 stracker sig utefter ventilsaten 7, 8 till lampligen som bladfiadrar utforda ventiler 9, 10 i luftinsugningskanalen 11 till motorn. Dessa ventiler bli &dor latt atkomliga efter handtagsdelens 3 upplyftning. Med 12 betecknas ett utrymme, avsett att innehalla ett luftfilter. Dettas ovre del Ochres av »stodplaneb 6, varf8r utrymmet 12 blir atkomligt baenom handtagsdelens avlyftning. I delens 3 kanaler kan Sven ett bransletillopp eller -limnstycke inmynna. As the drawing shows, the casing of the rock drill at the top is divided into three main parts, namely a crankcase part 1, one. fuel tank part 2 and a handle part 3. The support plane (at 4) between the crankcase part and the fuel tank part extends perpendicular to the crankshaft of the engine and the handle part 3 stands against the crankcase part 1 and the fuel tank part 2 according to a plane parallel to the crankshaft 5. The support plane 6 extends along the valve set 7, 8 to suitably as leaf faders challenge valves 9, 10 in the air intake duct 11 to the engine. These valves become easily accessible after lifting the handle part 3. By 12 is meant a space, intended to contain an air filter. This is the upper part of the ocher of the standing plane 6, whereby the space 12 becomes accessible by the lifting of the handle part. In the section's 3 channels, Sven can open an industry inlet or adhesive piece.

Pa. handtagsdelen sitta handtagen 14, 15, som anyandas av arbetaren under borrningsarbetet. Dessa kunna Sven anvandas vid avlyftningen av handtagsdelen 3. Pa. the handle part sit the handles 14, 15, which are anyandas by the worker during the drilling work. These can be used by Sven when lifting the handle part 3.

I vevhusdelen 1 finnes vevmekanismen 16, 17 samt ett pa. vevaxeln fast skovelhjul 18 till en flakt, som suger luft genom maskinholjet for kylning av motorn. Flaktinlopp bildas av oppningar 19 i en skold 20, som sitter pa vevhusdelens ena sida. In the crankcase part 1 there is the crank mechanism 16, 17 and one pa. the crankshaft fixed impeller 18 to a flat which sucks air through the machine housing for cooling the engine. Flattening inlets are formed by openings 19 in a shield 20, which sits on one side of the crankcase part.

Bransletanken 2 onasluter ve-vaxeln 5 och en darph fast startrnakanism 21 ringformigt och bildar en central halighet 22 f8r startmekanismen. Denna halighet dr tackt medelst ett lock 23. Bransletanken eller vevhusdelen kan vara forsedd med vartor 24 eller mellanldgg, varigenom bransletanken Mlles pa nagot avstand fran vevhusdelen 1 och varmeoverga.ngen fran vevhuset till bransletanken minskas. The fuel tank 2 unconnects the ve-gear 5 and a darph fixed starter mechanism 21 annularly and forms a central cavity 22 for the starter mechanism. This slowness is due to a lid 23. The fuel tank or crankcase part can be provided with warts 24 or intermediate layers, whereby the fuel tank is measured at some distance from the crankcase part 1 and the heat transfer from the crankcase to the fuel tank is reduced.

Motorcylindern 26 Sr nedtill insatt i vevhusdelen 1. Pa ritningen, fig. 1, visas forbranningsmotorkolven 27 i sitt oversta lage i cylindern 26. Stodplanet 4 mellan hransletankdelen och vevhusdelen Or belaget vid .ena sidan om cylinder. 26. Med 27' betecknas en skyddskapa kring motorcylindern. The engine cylinder 26 is inserted at the bottom in the crankcase part 1. In the drawing, Fig. 1, the internal combustion engine piston 27 is shown in its uppermost layer in the cylinder 26. The support plane 4 between the crankcase part and the crankcase part Or is located on one side of the cylinder. 26. '27' denotes a protective cap around the engine cylinder.

De olika huvuddelarna aro lampligen sammanhallna medelst latt lostagbara bultar. BulthM for fasthallning av handtagsdelen visas vid 28 i fig. 2 och 3. The various main parts are suitably held together by means of easily detachable bolts. BulthM for holding the handle part is shown at 28 in Figs. 2 and 3.
