The seal assembly includes a fixed seal and a seal runner rotatable with the shaft. The first axial face and a second axial face axially opposite the first axial face with respect to the axis. The first axial face includes a first surface rotatable against the seal, and the second axial face includes a trough portion. A second surface is angled relative to a radial baseline plane defined perpendicular to the axis, and a dam between the trough portion and the second surface. An oil source is positioned to provide oil into the trough portion.

Abstract: A free-flowing dry mix of various chemical components can be applied in its dried form, as is contemplated by typical powder coating operations, as well as dispersed within a liquid carrier and applied in liquid form. When liquefied, this bifunctional composition retains similar viscosity to liquid coatings, while simultaneously avoiding any reaction with or degradation by the liquid carrier. The liquefied powder is preferable to existing liquid coatings because it avoids the use of any volatile organic compounds or other solvents, whereas the final, cured coating produced by these bifunctional compositions are indistinguishable regardless of whether they are applied in dry or liquefied form.

Abstract: A system for a turbine engine includes a turbine engine component, a lubricant collection device and a plurality of lubricant circuits. The lubricant collection device is fluidly coupled with the turbine engine component. The lubricant circuits are fluidly coupled between the lubricant collection device and the turbine engine component. The lubricant circuits include a first circuit and a second circuit configured in parallel with the first circuit. Each of the lubricant circuits includes a lubricant pump. The first and the second circuits receive lubricant from the lubricant collection device, and direct the received lubricant to the turbine engine component.

Abstract: Aspects of the disclosure are directed to a system associated with an engine, comprising: a bearing compartment, a scavenge line coupled to the bearing compartment at a first end of the scavenge line that receives a fluid via the first end of the scavenge line, a fluid pump coupled to the scavenge line at a second end of the scavenge line to receive the fluid, and a flow control valve having a variable flow area and disposed in the scavenge line to control flow of the fluid in the scavenge line and the fluid pump.

Abstract: An assembly is provided that includes a shaft, a bearing, a stator seal element, a rotor seal element and a shield. The shaft extends along an axis. The bearing supports the shaft and receives lubrication fluid. The stator seal element circumscribes the shaft. The rotor seal element is mounted on the shaft axially between the bearing and the stator seal element. The rotor seal element forms a seal with the stator seal element. The shield substantially prevents the lubrication fluid from traveling axially away from the bearing onto the rotor seal element.

Abstract: A disclosed lubrication system for a gas turbine engine includes a primary passage defining a flow path for lubricant to a gas turbine engine and a bypass passage defining a flow path for lubricant around the gas turbine engine. The lubrication system further includes a primary lubrication pump including a reduced total flow capacity of lubricant with a reduced bypass lubricant flow relative to the total overall flow capacity.

Abstract: A system for conducting a maximum specific gravity test includes a sealable container for receiving and holding an asphalt mixture sample, a vacuum pump in fluid communication with the container for evacuating the container, a valve in fluid communication with the container, a shaker for shaking the container, and a controller. The controller can operate the system in a test mode by: (i) turning on the vacuum pump; (ii) automatically monitoring a vacuum pressure in the container with the vacuum pump on; (iii) automatically turning on the shaker when the monitored vacuum pressure reaches a target vacuum pressure value; (iv) automatically opening or closing the valve such that the monitored vacuum pressure in the container is maintained within a target vacuum pressure range for a predetermined period of time with the shaker on; and (v) automatically turning the shaker off at the end of the predetermined period of time.

Abstract: A lubrication system is disclosed. The lubrication system may be used in conjunction with a gas turbine engine for generating power or lift. The lubrication system utilized a flow scheduling valve which reduces lubricant flow to at least one component based on an engine load. The lubrication system may further include a main pump which may be regulated by an engine speed. Thus, a lubrication system which provides a lubricant to engine components based on the load and speed of the engine is possible. The system may improve efficiency of the engine by reducing the power previously spent in churning excess lubricant by at least one engine component as well as reducing the energy used by a lubricant cooler in cooling the excess lubricant. The lubricant cooler size may also be minimized to reduce weight and air drag due to the reduced lubricant flow.

Abstract: An assembly is provided for a turbine engine. This turbine engine assembly includes a rotating component, a turbine engine component and a lubrication system. The lubrication system is adapted to lubricate the turbine engine component where the rotating component rotates a first direction about an axis. The lubrication system is also adapted to lubricate the turbine engine component where the rotating component rotates a second direction about the axis.

Abstract: A fluid damping structure is provided that includes a damper ring. The damper ring includes an annular body a plurality of fluid check valves, and at least one fluid stop. The annular body extends circumferentially around an axial centerline, and is defined by a first end surface, a second end surface, an outer radial surface, and an inner radial surface. The outer radial surface and the inner radial surface extend axially from the first end surface toward the second end surface. The body includes one or more check valve passages. Each check valve passage extends axially from an open end disposed at the first end surface inwardly toward the second end surface, and is disposed between the inner radial surface and the outer radial surface. An inlet aperture extends between each check valve passage and the outer radial surface, and an outlet aperture extends between each check valve passage and the inner radial surface. Each fluid check valve is disposed in a check valve passage.
