Abstract

Išradimas susijęs su vidaus degimo varikliais, jų paleidimo sistemomis. Paleidžiama to paties dvipusio veikimo hidraulinio įtaiso (16, 16b, 16c) "stūmoklis cilindras" pagalba, kuris po paleidimo naudojamas jėgos perdavimui nuo variklio. Tarp hidraulinio akumuliatoriaus (5) su suspaustu skysčiu ir hidraulinių cilindrų ertmių (16b, 16c) įtaisomas reguliuojamas vožtuvas (12), kurio padėtis keičiama taip, kad hidraulinėse cilindrinėse ertmėse (16b, 16c) paeiliui susidarytų padidintas spaudimas. Paleidimo metu vienpusiai kontroliniai vožtuvai (8,9) įtaisyti tarp hidraulinių cilindrinių ertmių (16b,16c) ir pavaros (18), yra uždaryti tam, kad nuimtų apkrovimą nuo tūrinio/stūmoklinio siurblio.The invention relates to internal combustion engines, their start-up systems. The "piston cylinder" of the same duplex hydraulic device (16, 16b, 16c) is released, which is used to release the force from the engine after start-up. An adjustable valve (12) is arranged between the hydraulic accumulator (5) with compressed liquid and the hydraulic cylindrical cavities (16b, 16c), the position of which is changed so that the pressure in the hydraulic cylindrical cavities (16b, 16c) is increased in turn. During start-up, one-way control valves (8,9) are mounted between the hydraulic cylindrical cavities (16b, 16c) and the actuator (18), closed to remove the load from the volumetric / piston pump.
