Abstract
A cam actuated valve method and apparatus utilize an electronically controlled stepper motor driving a cam. A diaphragm type low flow, high accuracy diaphragm valve is positioned off axis with respect to the cam. A transmission translates linear motion of the cam to the valve diaphragm. High accuracy is maintained because the transmission is preloaded by pressure within the valve and the valve diaphragm.
