Abstract
The invention provides a swing drive device that is capable of energy conservation by limiting loss of hydraulic fluid pressure energy resulting from discharge of the hydraulic fluid pressure energy as thermal energy into the air during acceleration or deceleration of swinging action and transforming motion energy to electric energy during deceleration of swinging action, and also enables cost reduction by making components and parts compact.
