    • The invention pertains to a valve particularly suitable for sampling internal combustion engine lubricating oil while under pressure being used within the engine and consists of a valve body placed within a pressurized oil conduit. The body includes an orifice having a valve movable between open and closed positions by a sample collecting receptacle wherein one hand operation is readily achieved. The valve includes a proboscis suitable for piercing the sample receptacle diaphragm, and a spring produces a positive biasing force on the valve toward the closed position. A pressure balancing piston connected to the valve balances the force necessary for valve operation due to internal pressure. A removable cover protects the valve and proboscis when not in use.
    • 本发明涉及一种特别适用于在发动机内使用压力的同时对内燃机润滑油进行采样的阀,并且由置于加压油管内的阀体组成。 主体包括一个孔口,该孔口具有可在开放和关闭位置之间通过样品收集容器移动的阀门,其中容易实现单手操作。 该阀包括适于刺穿样品容器隔膜的长鼻子,并且弹簧在阀门朝向关闭位置产生正向偏压力。 连接到阀的压力平衡活塞由于内部压力平衡阀操作所需的力。 可拆卸的盖子在不使用时保护阀门和长鼻子。
