Title: Driving device for driving movable member of internal combustion engine by liquid pressure
Inventor: NISHIGAKI TAKAHIRO
IPC: F01L1/34
Filed: 2000-04-03
Abstract: PROBLEM TO BE SOLVED: To rapidly control the position of a movable member driven by liquid pressure, into a target position. SOLUTION: Driving liquid is supplied into a volume space, and the movable member is driven by the pressure of the liquid filled in the volume space. A control valve is provided for controlling the flow of the liquid supplied into the volume space. The opening quantity of the control valve is duty-controlled.
