Abstract
In an oil cooling system including an oil cooler housing (26) adapted to be face-sealed against a mating surface (46) including a port (47) connected to the high pressure side of a pressurized oil circulating system. The oil cooling system includes a base wall (60) on the housing (26) in a parallel relation to the mating surface (46), and an annular flange (52) extending from the base wall (60) and defining a radially-opening annular groove (54) that faces the port (47). An annular gasket (44) is located in the groove (54) between the flange (52) and the port (47) and has a flange-facing surface (68) that is complementary with the flange (52) on the side thereof defining the groove (54). The annular gasket (44), on the side thereof opposite the flange-facing surface (68), has a pressure-responsive surface (70) facing the port (47) so that, when the system is operating, oil under pressure from the port (47) will act against the pressure-responsive surface (70) to urge the gasket (44) into the groove (54) against the flange (52).
