Title: David M Evans: Innovator in Throttle Valve Technology
Introduction
David M Evans is a notable inventor based in Mendon, NY (US). He has made significant contributions to the field of throttle valve technology, holding 2 patents that showcase his innovative designs. His work primarily focuses on improving the efficiency and functionality of throttle valves used in various applications.
Latest Patents
One of his latest patents is for a throttle valve having a large diameter shaft with an integral valve plate. This rotary throttle valve features a first cylindrical bore for air flow between an inlet and an outlet, and a second cylindrical bore that is orthogonal to the first. The design includes a flow modulator that is rotatably disposed in the second bore, allowing for precise control of airflow. As the modulator rotates, it engages and disengages with the wall of the second bore, effectively opening and closing the valve.
Another significant patent by Evans is for a multiple-bore throttle valve with central shaft end-play restraint. This innovative design restrains the valve shaft from end play at a point between two flow bores. The valve body includes a passageway that intersects the valve shaft bore, and a pin is used to axially restrain the shaft. This design minimizes the effects of thermal expansion or contraction, ensuring consistent performance across multiple bore configurations.
