Title: Don E Avery: Innovator in Pump Technology
Introduction
Don E Avery is a notable inventor based in Honolulu, HI (US). He has made significant contributions to the field of pump technology, holding a total of 4 patents. His innovative designs focus on enhancing the efficiency and functionality of pumping systems.
Latest Patents
One of Avery's latest patents is the "Low head, high volume pump apparatus." This invention features an inner cylinder and a substantially larger outer cylinder, which are joined as two vertical concentric cylinders. Vertical partitions between the cylinders create an inlet chamber and an outlet chamber, with the latter being significantly larger in volume than the inner chamber. The inner cylinder contains a central pumping section positioned between upper and lower valve sections. Ports extend through the inner cylinder wall to the inlet and outlet chambers, with spring-loaded valves that close these ports. Tension springs and compression springs are utilized to manage the opening and closing of the inlet and outlet valves. The elastomeric valve flaps are supported by rigid curved backing members, and a piston rod moves a piston in the central section, connecting an inlet to the inlet chamber and an outlet to the outlet chamber.
Another significant patent is the "Active control system for high speed windmills." This invention matches a pump stroke to the operating speed of a high-speed windmill. The windmill drives a hydraulic pump for control, with changes in speed opening supply and exhaust valves to opposite ends of a hydraulic actuator. This mechanism allows for the lengthening and shortening of an oscillating arm, thereby adjusting the stroke of an output pump. When wind diminishes to a stall speed, the valves operate the hydraulic cylinder to shorten the oscillating arm to zero. A pressure accumulator in the hydraulic system provides the necessary force to supply hydraulic fluid under pressure, responding to the windmill shaft speed.
