Classification: CPC F  H | IPC F  H

Claim 0:
1. A valve control device, comprising:
a rod-shaped rotor configured to move forward or backward in a direction of a rotation axis by rotating the rotor in forward or reverse rotation,
wherein one end of the rotor is directly or indirectly connected to a valve body, and at least a part of the valve body is positioned in a flow path for fluid,
wherein the rotor moves in the direction of the rotation axis by rotating the rotor and changes at least one of:
a relative position of the valve body with respect to a valve seat that is closed by the valve body; and
a contact force between the valve body and the valve seat;
a pair of contacts for sandwiching the rotor, wherein relative movement of the pair of contacts rotates the rotor;
a moving unit comprising a piezoelectric element for causing the pair of contacts to perform relative movement; and
a drive control unit for controlling at least either one of the relative position of the valve body with respect to the valve seat or the contact force between the valve body and the valve seat by applying a voltage waveform to the piezoelectric element so as to cause the rotor to move forward or backward in the direction of the rotation axis by rotating the rotor in forward or reverse rotation direction by the pair of contacts.
