端口和回路的识别    
端口(壳体)     端口(转子)     回路    
5     20     向右行驶(前进)    
8     17     向右行驶(后退)    
9     16     向左行驶(后退)    
7     19     向左行驶(前进)    
3     18     排放    
11     15     行驶速度变换    

回转接头 (21) 能实现两个功能。 回转接头 (21) 将上部结构的主泵油和先导泵油输送到下部结构的行驶马达。 上部结构转动。 而下部结构不转动。 来自行驶马达的回油和来自行驶马达的排油经过回转接头 (21) 流向液压油箱。

壳体 (6) 用螺栓通过法兰 (12) 固定在上部结构上。 转子 (14) 用螺栓通过法兰 (13) 固定在下部结构上。 壳体 (6) 的端口对转子 (14) 的端口开放。 壳体 (6) 中的端口和转子 (14) 中的端口相连。

密封 (4) 和密封 (10) 在壳体 (9) 和转子 (14) 的滑动表面之间提供。 密封可防止油道之间发生漏油。
