One of Eldridge's key inventions is a low noise hydraulic servo valve. This fluid flow control valve is designed with a body that defines a chamber, which includes inlet, outlet, and actuating ports. These ports are essential for supplying and receiving fluid to and from external hydraulic machinery. The valve spool is formed with several lands and is slidably arranged in the chamber to control fluid flow through the ports. The unique arrangement of lands and ports allows for efficient fluid transmission, ensuring that some ports transmit fluid only outward while others allow fluid to flow into the chamber. Additionally, a matrix of restrictors is interposed in the ports that transmit fluid outward, optimizing the valve's performance.
