Abstract
An electrically controlled valve () includes a shaft (), a piezoelectric motor () affixed to an end of the shaft (), a controller (), a follower (), a valve member (), and a valve seat (). The piezoelectric motor () drives the shaft with a first direction and a second opposite direction. The controller () provides power to the piezoelectric motor () to move the shaft with a first speed and a second speed, the first speed being faster that the second speed. The follower () receives the shaft (), and slides relative to the shaft in response to the shaft moving with the first speed, and grips and moves with the shaft in response to the moving with the second speed and includes a valve member (). The valve member () moves with the follower (). The valve member () is configured to be moved by the follower () against the valve seat () to restrict fluid flow and to be moved by the follower () away from the valve seat to increase the fluid flow.
