<p>PURPOSE:To accurately control the action of connecting and disconnecting a clutch simplified in its structure by positioning a working chamber and a balance chamber interposing a piston and providing an oil passage for allowing oil to flow into the balance chamber. CONSTITUTION:A hydraulic cylinder device controls the action of a clutch disk 15 through a pressing mechanism 20. A working chamber 32 is positioned in an opposite side to a balance chamber 36, interposing a piston 31. Oil passages 37, 38, for allowing oil to flow into the balance chamber 36, are provided. A pressure of oil in the balance chamber 36 is controlled only by centrifugal force, generated by rotating the cylinder device, of the oil in the balance chamber 36. Thus enabling a structure to be simplified, the action of connecting and disconnecting a clutch can be accurately controlled.</p> |
