purpose of the accumulator?

### The purpose of the accumulator is to dampen pressure surges (made by positive displacement pump) and to provide a pressurized stored source of hydraulic oil (to minimize rapid cycling).

## Step1: Understanding the Role of an Accumulator### An accumulator in a hydraulic system is a device that stores energy in the form of hydraulic pressure. It is primarily used to dampen pressure surges. This is especially important in systems where a positive displacement pump is used. Positive displacement pumps generate pressure surges due to their operation mechanism, which involves forcing fluid into the discharge pipe. The accumulator helps to absorb these surges, ensuring the system operates smoothly.## Step2: Recognizing the Function as a Pressurized Stored Source of Hydraulic Oil### Aside from dampening pressure surges, the accumulator also serves as a pressurized stored source of hydraulic oil. This function is crucial in minimizing rapid cycling of the hydraulic system. Rapid cycling can lead to wear and tear on the system components, reducing their lifespan. By providing a stored source of pressurized hydraulic oil, the accumulator ensures a more consistent and controlled operation of the hydraulic system, thereby minimizing rapid cycling.
