Title: Thomas A. Watts: Innovator in Hydraulic Technology
Introduction
Thomas A. Watts is a notable inventor based in Ottawa, IL (US), recognized for his contributions to hydraulic technology. With a total of 4 patents, he has made significant advancements in the field, particularly in the design and functionality of hydraulic units.
Latest Patents
One of his latest patents is the "Hydraulic axial piston unit with multiple valve plates." This invention features an axial piston hydraulic unit that includes a valve plate assembly positioned between a head and a rotatable cylinder barrel. The assembly consists of a pair of valve plates stacked together to function as a single valve plate. This design defines a restricted flow path that provides initial communication between an approaching piston bore of the rotatable barrel and both an intake port and a discharge port extending through the pair of plates. The flow path is divided into two portions, with one defined in the valve plate adjoining the head and the other in the valve plate adjacent to the barrel. The stacked valve plates are hydraulically held together by a pair of pressure balancing devices.
Another significant patent is the "Variable displacement axial piston hydraulic unit." This unit includes first and second control pockets that are individually disposed between first and second arcuate-shaped fluid passages. It features a first electrohydraulic valve for controlling fluid flow between the first control pocket and the first fluid passage, as well as a second electrohydraulic valve for controlling fluid flow between the second passage and the second control pocket. A controller outputs control signals to these valves in response to a command signal, allowing for the tilt angle of a swashplate to be controlled to achieve desired operating parameters. Feedback signals from an angle detector, a pressure detector, and a speed detector help the controller determine when the desired operating parameter has been reached.
