An internal combustion engine unit including an internal combustion engine body, a balancer device attached to a lower portion of the internal combustion engine body, and an oil pan attached to the lower portion of the internal combustion engine body so as to surround the balancer device. The balancer device is disposed facing an outlet of an oil outflow hole, and the oil outflow hole is formed in the internal combustion engine body so as to return a lubricating oil in the internal combustion engine body to the oil pan.

An internal combustion engine is provided with oil intake pipes defining oil inlets on both sides of a tunnel type sump. Each oil intake pipe includes a valve which is operable to close the respective flowpath when the respective sump portion is tilted upwardly about the length axis of the engine. The inlets may be arranged to remain submerged in a minimum quantity of oil which is retained in each sump portion while the engine is tilted through its maximum angular range about both length and width axes.

A transmission for a motor vehicle includes a housing and a gear set. An oil drainage channel is formed by the housing and/or by an element connected to the housing and is arranged spatially underneath the gear set. The oil drainage channel includes at least one gear set-side inlet port, a closed underside, and an oil sump-side outlet port at one end of the oil drainage channel, which are designed and arranged in such that oil from the gear set enters the oil drainage channel through the at least one inlet port and is guided along the closed underside to the outlet port. A suction port of a hydraulic unit of the transmission is arranged in the oil sump spatially underneath the closed underside of the oil drainage channel and axially offset with respect to the outlet port.

A gas turbine engine in a shutdown mode comprises one or more rotatable shafts, a first oil sump, a second oil sump, and an oil drainage conduit fluidically connecting the first oil sump and the second oil sump. The one or more rotatable shafts are oriented with an axis of rotation less than 90 degrees from vertical. The first oil sump has a selected critical vertical level. The second oil sump is positioned at an elevation lower than the elevation of the first oil sump. The oil drainage conduit effects oil drainage by gravity from the first oil sump to the second oil sump to prevent the level of oil collected in the first oil sump from exceeding the selected critical vertical level.

An internal combustion engine unit including an internal combustion engine body, a balancer device attached to a lower portion of the internal combustion engine body, and an oil pan attached to the lower portion of the internal combustion engine body so as to surround the balancer device. The balancer device is disposed facing an outlet of an oil outflow hole, and the oil outflow hole is formed in the internal combustion engine body so as to return a lubricating oil in the internal combustion engine body to the oil pan.

Various implementations described herein are directed to an emergency lubrication system for a tiltrotor aircraft. The emergency lubrication system includes a pressurized material chamber, a lubrication chamber, a first valve between the pressurized material chamber and the lubrication chamber, a gearbox, and a second valve between the lubrication chamber and the gearbox. The first valve is configured to operate in a first mode when the emergency lubrication system is in a first configuration and a second mode when the emergency lubrication system is in a second configuration.

A fluid pump system for an aircraft has a rotatable component having first and second fluid ports, each port in fluid communication with a selected interior portion of the component, the portions being spaced from each other. A valve controls allows a first flow rate through the first fluid port and allows a second flow rate through the second fluid port when the component is in a first angular orientation. The valve allows a third flow rate through the first fluid port and allows a fourth flow rate through the second fluid port when the component is in a second angular orientation.
