手册提到

在高压降低的情况下的操作
When the HP decreases but remains sufficient to keep the bypass valve in the active mode, the piston retracts under extemal forces. These forces are higher than those delivered by the large chamber pressure. They cause the servovalve spool valve to open in the direction which connects the large chamber to the pressure line.
当HP减小但仍足以使旁通活门保持在工作模式时，活门在外力作用下缩起，这些力高于大腔室压力所传递的力。它们使伺服活门滑阀在大腔室与压力管路连接的方向上打开。
Then the check valve (2) allows to servovalve retraction at low speed as the fluid transits through the servovalve leakages.
当液压油通过伺服活门渗漏而转移时，单向活门(2)允许伺服活门以低速收回

有两点疑问：
1大腔指的是哪个腔
2为什么液压油通过伺服活门渗漏而转移时，单向活门(2)允许伺服活门以低速收回
