Abstract
A valve drive control apparatus having a communication unit for communicating a flow-in-side tube path with a flow-out-side tube path, which guide a fluid member, and a control medium storage chamber into which an attenuation characteristic control medium is filled. The valve drive control apparatus further includes an elastic deform member for defining the communication unit and the control medium storage chamber, a drive unit for pressuring the attenuation characteristic control medium so as to deform the elastic deform member via the attenuation characteristic control medium, and also a control unit for controlling the drive unit based on a drive control valve obtained from a valve drive characteristic representative of a relationship between a deform amount of a valve mechanism unit and a drive pressure value of the valve mechanism unit. The valve drive characteristic is acquired from a dynamic fluid characteristic of the fluid member and a dynamic fluid characteristic of the attenuation characteristic control medium.
