Description
rv3121ss-7 _2 Enligt uppfinningen är vid den visade utföríngsformen en 'dräneringsledning 6 dragen från motorns l hus till en uppsam- lingstank 7. Från ett bottenutlopp i denna går en ledning 8 via en backventil 9 till motorns l tryckledning Ä i en punkt efter 5 manöverventilen 5. Med 10 är motorns returledning till förråds- tanken 2 betecknad. rv3121ss-7 _2 According to the invention, in the embodiment shown, one drain line 6 drawn from the housing 1 of the engine to a collection tank 7. From a bottom outlet in this, a line 8 passes via a non-return valve 9 to the engine l pressure line Ä at a point after 5 control valve 5. With 10, the motor return line to the supply tank 2 designated.
Det ovan beskrivna arrangemanget verkar på följande sätt: Under drift dränerar motorn l utläckt olja till tanken 7. När manöverventilen 5 stängs, retarderas motorn och arbetar under 10 denna tid till följd av sin tröghet som pump för att via den nu öppnade backventilen 9 suga den i tanken 7 ansamlade oljan till motorns tryckledning H. Härvid sker retardationen av motorn mjukt, vilket motverkar kavitationsskador och dessutom möjliggör ett högre varvtalsområde för motorn. 15 Det ovan beskrivna 2-slangsystemet kan med fördel användas vid t.ex. vikbromskranar med utskjutsbom för tillförsel och retur av olja ut till resp. från kranarmsspetsen, där fällaggregatet eller annat verktyg med olika funktioner är placerat. Konventio- nellt används separata hydraulledningar (tryck och retur) för 20 varje funktion. Detta kräver avsevärt större utrymme än om enligt uppfinningen blott två hydraulslangar används, och elektriskt styrda riktningsventiler för de olika funktionerna placeras ute i kranarmsspetsen. 7 7 Uppfinningen är ej begränsad till det ovan beskrivna utföran- 25 det utan olika modifikationer är tänkbara, såsom att den separata tanken för dräneringsoljan kan bildas av en på motorn direkt på- byggd samlingskammare, liksom enkelriktningen hos oljan ut från kammaren kan ombesörjas på annat sätt än medelst den visade back- ventilen. f. - ' ' - 13535? : a: 5"., 9: _ ' V Qïj-Lïxßasm .The arrangement described above operates as follows: During operation, the engine l drains leaked oil to the tank 7. When the control valve 5 closes, the engine decelerates and works underneath 10 this time due to its inertia as a pump to via it now opened the non-return valve 9, suck in the oil accumulated in the tank 7 motor pressure line H. In this case the deceleration of the motor takes place smoothly, which counteracts cavitation damage and also enables one higher engine speed range. The 2-hose system described above can be used to advantage at e.g. folding brake cranes with extension boom for supply and return of oil out to resp. from the crane arm tip, where the folding unit or other tool with different functions is placed. Conventional Separately, separate hydraulic lines (pressure and return) are used for 20 each function. This requires considerably more space than if according to the invention uses only two hydraulic hoses, and electrically controlled directional valves for the various functions are placed outside in the crane arm tip. 7 7 The invention is not limited to the embodiment described above. Without various modifications are conceivable, such as the separate the tank for the drainage oil can be formed by a directly on the engine built collection chamber, as well as the unidirectional direction of the oil from the chamber can be provided in other ways than by means of the the valve. f - '' - 13535? : a: 5 "., 9: _ 'V Qïj-Lïxßasm.
