Zusammenfassung: | PURPOSE:To protect an engine from overheat even after long term continuous operation, by cooling the operation liquid sequentially through the combination of booster pump and drain path. CONSTITUTION:The operational liquid leaked from a loop path 29 through a check valve 34 into the drain space 35 of a casing 4 is led out through a drain path 37 to a tank 38 at the outside of a liquid engine 1 and cooled by a cooler 43. The cooled operational liquid is returned to the loop 29 through a boost pump 44. Consequently the liquid engine 1 can be protected from overheat. |
