An auxiliary oil supply apparatus for a rotating device (50, 51), the rotating device comprising a primary oil supply (52), a rotating component (50) and a static component (51) situated radially outwardly of a centre of rotation of the rotating component (50) and arranged to collect oil (58) held radially outwardly from the rotating component (50) as the rotating component rotates. The auxiliary oil apparatus comprises a scoop (56) associated with the rotating component (50) and is responsive to a change in a known parameter to move between a first position in the static component (51) to a second position between the static component (51) and the centre of rotation.

A fluid delivery device includes a body and a reed. The body has a primary inflow passage, a secondary inflow passage, and an outflow passage. The reed is disposed at least partially within the body. The reed is configured to move to a first position when a fluid flows from the primary inflow passage and move to a second position when the fluid flows from the secondary inflow passage.

A control apparatus for a vehicle drive-force transmitting apparatus which defines a first drive-force transmitting path provided with a first clutch and a two-way clutch and a second drive-force transmitting path provided with a continuously variable transmission and a second clutch. The control apparatus switches the two-way clutch from its lock mode to its one-way mode, when the second drive-force transmitting path is to be established in place of the first drive-force transmitting path. The drive-force transmitting apparatus includes a hydraulic actuator configured to control switching of the two-way clutch between the lock mode and the one-way mode. When a request for establishing the second drive-force transmitting path in place of the first drive-force transmitting path is made during forward running of the vehicle with the two-way clutch being in the lock mode, the control apparatus executes a dither control for fluctuating a hydraulic pressure applied to the hydraulic actuator.

A fan drive gear system for a turbofan engine according to an exemplary embodiment of this disclosure, among other possible things includes a sun gear that is rotatable about an axis, a plurality of intermediate gears driven by the sun gear, and a baffle that is disposed between at least two of the plurality of intermediate gears for defining a lubricant flow path from an interface between the sun gear and at least one of the plurality of intermediate gears. The baffle includes a channel with at least one ramp portion directing lubricant.

The oil storage structure includes an oil pan that closes a lower opening of the transmission case and forms an oil pool in a lower space inside the transmission case, and a strainer having a suction port for oil located in the oil pool. The suction port for the oil is provided so as to face a bottom wall portion of the oil pan with a gap in between, and the bottom wall portion of the oil pan is provided with a protruding portion protruding toward the suction port, with the protruding portion being formed in a direction across the suction port as viewed from the bottom wall portion.

An agricultural system including an agricultural baler and a control unit. The baler includes a driveline including at least one heat generating component; a rotatable flywheel; a rotary input shaft connectable by the driveline to the rotatable flywheel; and at least one pump for supplying cooling fluid at a cooling fluid pressure to the at least one heat generating component. The control unit is configured to: receive baler-data indicative of one or more operating conditions of the agricultural baler; receive cooling-pressure-data indicative of a flow of the cooling fluid supplied by the at least one pump; set a threshold-condition based on the baler-data; and provide a control-signal to the agricultural baler based on a comparison between the cooling-pressure-data and the threshold-condition.

A control device for an automatic transmission is provided, which includes a vehicle-propelling friction engagement element configured to be engaged when a vehicle starts traveling, an other friction engagement element, a vehicle-propelling friction engagement element temperature detector configured to detect a temperature of the vehicle-propelling friction engagement element, an input speed detector configured to detect an input speed of the automatic transmission, and a processor configured to execute lubricant supply control logic to control supply of lubricant to the vehicle-propelling friction engagement element and the other friction engagement element. The lubricant supply control logic switches the supply amount of lubricant to the vehicle-propelling friction engagement element according to the temperature of the vehicle-propelling friction engagement element, and switches the supply amount of lubricant to the other friction engagement element according to the input speed.
