Abstract
An improved ported mechanism such as an engine, compressor or the like. The mechanism includes a housing defining a chamber and a liner is disposed within the housing and supported thereby to define the chamber walls. Coolant passages extend between the housing and the liner and a piston is movable within the chamber. A port receiving opening is located in the housing and a port in the liner is provided and includes a tubular element extending from the liner into the opening. A fluid-impervious heat transfer impeding structure is exteriorly of and surrounds the tubular element and is disposed within the opening. A flexible seal is in the opening and interposed between the housing and the heat transfer impeding device so that the seal prevents leakage at the port and the impeding device prevents rapid deterioration of the seal.
