Compact excavators are designed to perform a variety of functions within a small vehicle envelope. The vehicle size presents constraints on the structure as well as the hydraulic system. A unique open-center hydraulic system has been designed and developed which optimizes system performance, size, and cost. The hydraulic circuit was designed to provide smooth, reliable operation of as many as ten vehicle functions simultaneously.
