Abstract:
A pair of independent cylinder holes 3, 3 are formed in a cylinder tube 2 of a flat outer shape. When a pressurized fluid is alternately supplied into the cylinder tube 2 through a port 7 formed in an end cap 5, the internal pressure for operating the cylinders acts uniformly on the cylinder tube 2 greatly decreasing stress and deflection of the cylinder tube 2.
