We developed a gasket to seal even if the surfaces of the sealing land are not solid-contacted and examined the possibility to reduce the leakage from the land by controlling the viscosity of liquids. The test rig consisted of two metal disks, a Peltier module (83 W), a platinum resistance thermometer (Pt100), a reservoir, and a flow meter. The outer diameter and thickness of the disk was 200 mm and 10 mm, respectively. In the experiment, oil temperature, seal pressure (height: 0.5, 1.0, 1.6 m), land gap (0.05, 0.1, 0.2 mm), land size (40, 30, 20 mm), and oil type (VG22 and 46) were selected as the test parameters. The sealing land of the test gasket was cooled and heated and the leakage was measured. The experimental results revealed that i) the leakage was varied as the oil temperature and viscosity were changed, ii) the repeatability and reversibility of the phenomena were measured and confirmed, and iii) these results were obtained for all oils tested.
