Title: The Innovations of William R. Kerr
Introduction
William R. Kerr is an accomplished inventor based in Peru, MA (US). He is known for his significant contributions to the field of hydrostatic transmissions. His innovative approach has led to the development of a unique patent that enhances the functionality of these systems.
Latest Patents
Kerr holds a patent for a "Continuously variable hydrostatic transmission including a pulse width." This invention features a controller that adjusts the ratio of a continuously variable hydrostatic transmission based on the angular position of a swashplate. The design includes an actuator with a cylinder that slidingly receives a piston, defining a pair of chambers. Two solenoid valves connect each chamber selectively to sump pump pressure or atmospheric pressure. These valves are energized with a stream of pulses, creating differential fluid pressures that produce movement of the piston. This movement is linked to the swashplate, allowing for precise adjustments in its angular position. The rate of change of the swashplate's angular position is controlled by pulse width modulation of the pulse stream.
