具有内部通道的致动器装置
摘要：
公开了具有内部通道的致动器装置。实例装置包括致动器壳，其具有加载装置用以限定上压强腔和下压强腔。该上压强腔相对于该下压强腔。轭被用以耦接该致动器壳至流体阀。内部通道形成于该轭的主体中，用以流体地耦接控制流体至该第一或该下压强腔至少其中之一。流体连接器组件被置于该致动器壳中，用以流体地耦接该内部通道至该上压强腔。该加载装置位于该轭的该内部通道和该上压强腔之间。
摘要（英）：

Actuator apparatus having internal passageways are disclosed. An example apparatus includes an actuator casing having a load apparatus to define an upper pressure chamber and a lower pressure chamber. The upper pressure chamber is opposite the lower pressure chamber. A yoke is to couple to the actuator casing to a fluid valve. An internal passageway is formed in a body of the yoke to fluidly couple a control fluid to at least one of the first or the lower pressure chamber. A fluid connector assembly is positioned in the actuator casing to fluidly couple the internal passageway to the upper pressure chamber. The load apparatus is between the internal passageway of the yoke and the upper pressure chamber.
