Abstract
A dual tandem composite cylinder composite cylinder assembly including a pair of composite cylinder barrels in series, and a center dam connection between adjacent ends of the cylinder barrels formed by providing an interference between external ramps on the adjacent ends of the cylinder barrels and correspondingly sloping internal ramps on respective clamping rings and/or split spacers between the clamping rings and external ramps for clamping the external ramps against a center dam between the adjacent ends of the cylinder barrels. The clamping rings may be connected together by means of a plurality of bolts which, when pretensioned, force the clamping rings toward each other to cause a compression load to be applied at the ramp surfaces. Alternatively, a tensioning nut having internal threads of opposite hand in opposite ends of the nut in threaded engagement with the clamping rings may be used in place of the bolts to move the clamping rings toward each other.
