前轮转弯系统中旁通活门的作用?( ) Nose wheel steering system bypass valve function:
A. 隔离转弯作动伺服管路 Isolation of nose wheel steering actuator servo line
B. 给转弯作动伺服管路供压 supply pressure to nose wheel steering actuator servo line
C. 隔离转弯作动伺服回油管路 Isolation of nose wheel steering actuator servo return pipe
答案:A
解析：这道题目询问的是前轮转弯系统中旁通活门的作用。旁通活门一般用于控制液压系统中流体的流动。答案中的A选项"隔离转弯作动伺服管路"指的是通过打开或关闭旁通活门来控制转弯作动伺服管路的流动，从而实现前轮转弯系统的隔离。
