FIRE ENGINE

Japanese Patent JP3909076

B2

PROBLEM TO BE SOLVED: To provide a fire engine which needs only the necessary number of signal lines, does not require continuous operation of a signal generator, and quickly adjusts a rotational speed of an engine for driving a pump for discharging a fire fighting fluid.
SOLUTION: A plurality of signal generators 21, 22 generate signals of a value corresponding to the operational amount and a direction of the operation from a reference position P of operational members 21a, 22a continuously in terms of time. A selecting part 31 selects signals transmitted from either one of the signal generators 21, 22. A part 33 for generating a signal for adjusting a rotational speed has an accumulating part 32 which accumulates time series values of signals selected by the selecting part 31 in a manner to increase gradually when the operational members 21a, 22a are operated in one direction from the reference position P and accumulates the time series values in a manner to decrease gradually when the operational members 21a, 22a are operated in the other direction from the reference position P, and generates signals for adjusting a rotational speed of the engine 8 for driving a pump for discharging a fire fighting fluid depending on the value accumulated in the accumulating part 32.
