Abstract:

PURPOSE: To vary the moving amount and moving term of a drive action of a drive device by a cam simultaneously.

CONSTITUTION: An oil pressure is generated by a send cam 1 and a return cam 4. This oil pressure is controlled by a feed oil pressure control valve 7 and a return oil pressure control valve 8, and moves an operation piston 9 to drive a drive shaft 11 in an operation cylinder 10. The operation timing of respective cams 1, 4 and respective oil pressure control valves 7, 8 is varied by the varying mechanism 21 of a rotational angle and the varying mechanism 22 of an oil pressure control valve action timing. The drive device has these factors.
