摘要： A piston and cylinder assembly includes a housing defining a bore. A piston is sized to reciprocate in the bore. A first sealing member provides a sealing engagement between the piston and a wall of the bore. A first bushing, of a first material, is around a first portion of the piston toward a first end of the piston. A second bushing, of a second material, is around a second portion of the piston toward a second end of the piston. The first and second bushings guide the piston within the bore. The first material is different than the second material.
摘要翻译： 活塞和气缸组件包括限定孔的壳体。 活塞的尺寸可以在孔中往复运动。 第一密封构件提供活塞和孔的壁之间的密封接合。 第一材料的第一衬套围绕活塞的第一部分朝向活塞的第一端。 第二材料的第二衬套围绕活塞的第二部分朝向活塞的第二端。 第一和第二衬套将活塞引导到孔内。 第一种材料与第二种材料不同。
