This invention relates to a pneumatic power cylinder dash-pot piston which is formed of an elastomers cylinder and a sleeve and having a space between the interior wall of the cylinder and the exterior wall of the sleeve, and the space is filled with a fluid. The piston is connected to a power shaft of a power cylinder. The sleeve is corrugated and is formed integrally with the cylinder so as to prevent the escape of the fluid through a joint. The interior cylinder wall is tapered from the center thereof in opposite directions so that the cylinder, engaged by a disk on the power shaft, gradually comes into contact with an end portion of the cylinder whereby the corrugations of the sleeve are compressed at one end and the other corrugations are straightened.
