Description of the Related Art As shown in FIG. 2, the opening / closing drive of a starting valve 2 arranged in each cylinder 1 of a conventional diesel engine moves a control handle 3 to a starting position at the time of engine starting operation, and controls in conjunction with this. The air control valve 4 is opened, and by opening the control air control valve 4, the automatic stop valve 6 connected to the air tank 5 is opened,
A cylinder (not shown) for each cylinder is opened in synchronization with the engine rotation for a certain period from after the top dead center to before the bottom dead center. The air in the air tank 5 is introduced into and driven to open and close, and thus a high pressure is supplied to each cylinder 1 to obtain a force for pushing up a piston (not shown), whereby a crankshaft (not shown) is also obtained. Is rotated to obtain the rotation speed required for normal operation with the fuel, which is the next step.

計にも影響を与えている。As described above, various diesel engines having an air-driven starter valve, especially those used for marine vessels, require a large amount of air for frequent engine start / stop operations due to marine vessel maneuvering. Consume. Also, during a crash astern (engine emergency stop and reverse rotation start after engine stop), the starting valve is opened at the compression top dead center to release compressed cylinder air and obtain braking force. Even in the series of operations in which the reverse rotation is started, a large amount of air is required to drive the control valve during the braking cycle that lasts several minutes. In order to provide for these, the conventional example having the air-driven start valve requires a large air tank, which also affects the basic design of the hull.

The present invention is a start valve 2 arranged in each cylinder 1 of a diesel engine. In addition, a hydraulic valve 10 for controlling the hydraulic pressure from the hydraulic power source 8 according to the rotation of the engine is connected, and the starting valve 2 is opened and closed via the hydraulic valve 10.

As a result, air is not consumed for opening / closing the start valve during frequent engine start / stop operations or crash asterns, and a faster opening / closing speed can be obtained compared to air-driven start valves, making it more appropriate. It is possible to obtain a proper start-up valve opening / closing timing.

Reference numerals 1 to 6 in the drawing denote the same parts as those in the conventional example shown in FIG. 2 and the description thereof will be omitted. Further, in the present invention, a hydraulic valve 10 for controlling the hydraulic pressure from the hydraulic pressure source 8 via the valve control device 9 to the start valve 2 according to the rotation of the engine.
And the starting valve 2 is opened and closed via the hydraulic valve 10.

作可能回数が増え余裕となる。As described above, according to the present invention, a hydraulic valve for controlling the hydraulic pressure from a hydraulic pressure source according to the engine rotation is connected to a start valve arranged in each cylinder of a diesel engine, and the hydraulic valve is connected via the hydraulic valve. Since the start valve is driven to open and close, it does not consume a large amount of air to drive the control valve during engine startup and crash astern, so it is the same as the conventional air-driven start valve. If the size of the air tank is large, the number of operations is increased and there is a margin.

Further, since a proper valve opening / closing timing can be obtained by a high valve opening / closing speed, the effect of the braking cycle at the time of crash astern can be enhanced.
