Pumpkins can stash energy on their insides away like a locked safe. This is analogous to the way accumulators function in machines. They store power and discharge it when we need it.
For machines, accumulators are kind of like pumpkins. They store energy when there’s too much of it and return it when we need it. Just as pumpkins contain their seeds until they develop into new plants.
There is also hydraulic fluid inside of the accumulator that aids in storing and transferring energy. It’s the juice in the pumpkin that holds everything together. The accumulator doesn’t work great without hydraulic fluid.
Accumulators require the correct pressure to function how we want them to function. They could pop like balloons if there is too much pressure. With not enough, they can’t store the energy. It’s like picking out the right pumpkin for Halloween, but the reverse — not too big (though also not too small).
If machines have accumulators, they can get better. It’s like extra batteries for your toy so it doesn’t run out of juice too quickly.” The accumulator helps keep the machine running for longer, much like a good night of sleep helps you feel prepared to take on the day.
Accumulators come in as many varieties as there are shapes and sizes of pumpkins. Some are large to fit heavy machines, while others are small to fit in narrow spaces. Each has its own special job, just as every pumpkin can coax out something different.
