It works as shown in Figure 2b, when the work when the system is high pressure, EF mouth also in high pressure, high pressure Balance Valves unloading of oil equivalent one-way valve open and the unloading valve 3 1 contact; when the pressure exceeds the safety valve unloading having a set pressure, unloading relief valve to open, the return oil through oil path b to uninstall the spool 4, left, unloading Safety valves valve spring to overcome the spring force 5, unloading spool shifted to the right, EF population of high-pressure oil through direct discharge port T Dutch tank.

其工作原理如图2b所示，当工作系统处于高压状态时，EF口也处于高压状态，高压油打开等值卸荷单向阀3与卸荷安全阀1接触；当压力超过卸荷安全阀调定压力时，卸荷安全阀开启，其回油经油道b到卸载阀芯4左端，克服卸载阀弹簧5的弹簧力，卸载阀芯右移，EF口的高压油经T口直接卸荷油箱。

Background: The stem cell is a kind of cell which can keep alive for a long term and has a few of differentiation potencies. While, the progenitor cell is a kind of cell keeping one or double ways of differentiation and the capability of its differentiation, self-renew and self-maintenance is confined.
