PURPOSE:To enhance the startability of an engine for an industrial vehicle which performs various handling operations by means of a hydraulic fluid securable out of a hydraulic pump being by the engine. CONSTITUTION:A bypass pipeline 17 is installed in space between a discharge pipeline 9 and an inlet pipeline 7 of a hydraulic pump 3, while a selector valve gear 19, which interconnects the bypass pipeline 17 at the time of starting an engine 1 and simultaneously interrupts the pipeline 17 after starting the engine 1, is installed in the point midway in the bypass pipeline 17. Accordingly, at time of engine starting, a hydraulic fluid in the bypass pipeline 17 and thereby load at the side of a starter motor 23 of the engine 1 is relatively lightened, thus rotational frequency of the engine 1 goes up so quickly, so the engine 1 is surely startable. |
