Measuring check motion through pressure sensing |
摘要 |
A valve using a pressure control cavity (70) to control valve (22) position can implement a pressure to sensor (78) to determine the pressure within the control cavity to determine whether pressure is presently acting upon the valve. The pressure sensor can provide a feedback signal to a control module allowing the control module to control timing of the valve. <IMAGE>
