Integrated one-way valve

A one-way valve cartridge for a flow assembly, the one-way valve cartridge including a housing having an axial orifice formed therein. A guide ring is coupled to the housing. A piston is disposed in the housing and is in sliding relationship with the guide ring. The piston is configured to reciprocate between a closed position to seal the axial orifice and an open position to allow flow of fluid through the axial orifice. A spring urges the piston into a closed position to seal with the housing. 一种用于流动组件的单向阀阀芯，该单向阀阀芯包括壳体，该壳体具有形成于其中的轴向孔口。引导环联接至壳体。在壳体中设置有活塞，并且该活塞与引导环成滑动关系。活塞构造成在用以密封轴向孔口的关闭位置与用以允许流体通过轴向孔口的流动的打开位置之间往复运动。弹簧将活塞推动到关闭位置中以与壳体密封。
