Oil cooler with a retained, blow-out proof, and extrusion resistant gasket configuration
摘要：
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).
摘要（中）：

在一种油冷却系统中，包括一个油冷却器壳体（26），该油冷却器壳体适于面对密封在一个配合表面（46）上，该配合表面（46）包括连接到加压油循环系统的高压侧的端口（47）。 所述油冷却系统包括与所述配合表面（46）平行的壳体（26）上的基壁（60）和从所述基壁（60）延伸并限定径向开口 面向端口（47）的环形槽（54）。 环形垫片（44）位于凸缘（52）和端口（47）之间的凹槽（54）中，并且具有与凸缘（52）在其侧面上互补的与凸缘相对的表面（68） 凹槽（54）。 环形垫片（44）在与凸缘对向表面（68）相对的一侧上具有面向端口（47）的压力响应表面（70），使得当系统运行时，来自 端口（47）将作用在压力响应表面（70）上以将垫圈（44）推入凹槽（54）中以抵靠凸缘（52）。
