    • A Stirling engine comprising: an engine housing (52) which includes compression and expansion cylinders (22, 24) and a crankcase (50); a compression piston (12) and an expansion piston (14) positioned in the respective cylinders (22, 24) in the housing (52) and coupled to a crankshaft (20) via bearing means (44); the crankshaft (20) being positioned in the crankcase area which is defined by the pistons (12, 14) and the housing (52); CHARACTERISED IN THAT the pistons (12, 14) include pad means (40, 42) between the pistons (12, 14) and their respective cylinders (22, 24) to minimize the friction therebetween during reciprocal movement thereof, the crankcase (50) is pressurized to inhibit the passing of working gas past the pistons (12, 14); and means (48) are provided for cooling the crankshaft (20) and the bearing means (44) thereby eliminating the need for oil in the crankcase (50).
    • 一种斯特林发动机,包括:发动机壳体(52),其包括压缩和膨胀气缸(22,24)和曲轴箱(50); 压缩活塞(12)和膨胀活塞(14),其定位在所述壳体(52)中的相应气缸(22,24)中,并通过轴承装置(44)联接到曲轴(20)。 曲轴(20)定位在由活塞(12,14)和壳体(52)限定的曲轴箱区域中; 其特征在于,活塞(12,14)包括在活塞(12,14)和它们各自的气缸(22,24)之间的垫装置(40,42),以在其往复运动期间最小化它们之间的摩擦,曲轴箱(50) 被加压以阻止工作气体通过活塞(12,14); 并且提供用于冷却曲轴(20)和轴承装置(44)的装置(48),从而消除了对曲轴箱(50)中的油的需要。
