A seal member includes: an inner circumferential surface surrounding a central axis; an upper surface connected to one end of the inner circumferential surface in an axial direction of the central axis; a lower surface connected to another end of the inner circumferential surface in the axial direction; and a protrusion that is provided continuously to the inner circumferential surface so as to surround the central axis and that includes a first portion inclined to the upper surface side toward one side in a circumferential direction of the central axis and a second portion inclined to the lower surface side toward the one side in the circumferential direction.

A winder for a threaded connection of two axially aligned bodies where a first body comprises a male portion at an end connection portion and a second body has a female portion at an end connection portion. The female portion comprises a sleeve with a threaded portion on an internal face. The winder includes a winder ring encircling the male portion. The winder ring forms an internal surface and an external surface having a threaded portion. The internal surface of the winder ring includes a number of parallel grooves that are perpendicular to a rotational axis of the winder ring. A further male portion comprises external, circular grooves complementary to internal, circular ridges of the winder, and a threaded connection between two axially aligned bodies where the connection comprises the winder and the male portion.

A flexible, thermal-isolating tube includes a first fluid flow channel portion having a dual-walled configuration, a second fluid flow channel portion having a dual-walled configuration, and a bellows disposed between and coupled to each of the first and second fluid flow channel portions. The flexible, thermal-isolating tube, including each of the first and second fluid flow channel portions, and the bellows, is configured as a unitary structure. The flexible, thermal-isolating tube is manufactured using an additive manufacturing process. The flexible, thermal-isolating tube is disposed within a gas turbine engine

A torque link assembly may comprise an upper torque link, a lower torque link, and a torque link pin. The upper torque link may define an upper hydraulic fluid channel. The lower torque link may define a lower hydraulic fluid channel. The torque link pin may fluidly couple the upper hydraulic fluid channel to the lower hydraulic fluid channel.

A rotary multiport greasing valve having an outer sleeve and an inner sleeve within the outer sleeve. The outer sleeve has at least one inlet port and at least 2 outlet ports. The inner sleeve has an inlet port, a central passageway, and an outlet port. The inner sleeves inlet port is fluidly connected to the outer sleeve's inlet port. The inner sleeve rotates within the outer sleeve so that the inner sleeves outlet port is circumferentially aligned with a selected outer sleeve outlet port creating a fluid pathway from the outer sleeve inlet port into the inner sleeve's inlet port through the central passageway through the inner sleeve's outlet port and finally through the outer sleeves outlet port to create an open flowpath. In certain instances, the inner sleeve inlet port is longitudinally shifted so as not to align with any portion of an outlet sleeve outlet port.
