摘要： A fitting 42 for attaching to double wall tubes includes a body, a fitting center port, an outer seal 60, a tube connection, a pad connection 72, an inner seal 62, a groove 78, and a diagnostic port 76. The body has a first surface on a first side of the body and a second surface on a second side of the body. The fitting center port extends through the body for passing a primary fluid flow. The tube connection is on the first side of the fitting, and includes an inner connection and an outer connection. The groove 78 is in the second surface surrounding the inner seal 62 and the groove 78 is configured to receive an outer seal 60. The diagnostic port 76 is in the second surface for transferring a collected fluid through the body to the outer connection.

摘要： A pump assembly includes a housing (14) having a first lobe (18A). A shaft rotates (20) at least partially inside the housing (14) about an axis and has an outer surface (20S). A base member (16A, 30A, 30B, 30C, 30D, 44A, 44B) is mounted on the shaft (20) so as to rotate with the shaft (20). The base member (16A, 30A, 30B, 30C, 30D, 44A, 44B) is mounted on a location of the shaft (20) such that at least a portion of the base member (16A, 30A, 30B, 30C, 30D, 44A, 44B) is located within the first lobe (18A). A fin (32) protrudes generally axially from the base member. The fin (32) is configured to extend outward from the outer surface (20S) of the shaft (20). Rotation of the shaft causes the fins to scoop lubricant out of the lobe (18A), to avoid undesired accumulation of lubricant.
摘要翻译：泵组件包括具有第一叶片（18A）的壳体（14）。轴（20）至少部分地围绕轴线在壳体（14）内旋转并且具有外表面（20S）。基座构件（16A，30A，30B，30C，30D，44A，44B）安装在轴（20）上以便与轴（20）一起旋转。基座部件（16A，30A，30B，30C，30D，44A，44B）安装在轴（20）的位置上，使得基座部件（16A，30A，30B，30C，30D， 44A，44B）位于第一叶片（18A）内。翅片（32）从基座部件大致轴向突出。翅片（32）构造成从轴（20）的外表面（20S）向外延伸。轴的旋转导致翅片将润滑剂从叶片（18A）中舀出，以避免不期望的润滑剂积聚。

摘要： A gas turbine engine (20) may have a fan section (22) that includes a variable pitch mechanism for changing the pitch of fan blades (105). The gas turbine engine (20) may include a fan hub (110) that is rotatable about an engine central longitudinal axis (A-A') of the gas turbine engine (20) and a blade receiver (120) that is for holding a fan blade (105) and that is rotatably coupled to the fan hub (110) and may be rotatable about a radial axis of the gas turbine engine (20). The gas turbine engine (20) may include a spring element (130) disposed between the fan hub (110) and the blade receiver (120) to bias the blade receiver (120) radially outward and an annular retaining ring (140) may be disposed around the radial axis and between the fan hub (110) and the blade receiver (120) to limit radially outward movement of the blade receiver (120) to prevent the blade receiver (120) from decoupling and disengaging from the fan hub (110).

摘要： A gas turbine engine (20) may have a blade receiver (120) for holding a fan blade (105, wherein the blade receiver (120) is rotatable about a radial axis (106) of the gas turbine engine (20). The gas turbine engine (20) may also include a variable pitch mechanism (170) comprising an actuation arm (172). The gas turbine engine (20) may also include a splined index ring (160) disposed between the actuation arm (172) of the variable pitch mechanism (170) and the blade receiver (120). The splined index ring (160) may include an outer spline (163) and an inner spline (164).
