Abstract: A dual stage accelerator pedal assembly is provided that is capable of communicating various vehicle operating conditions to the driver as well as notifying the driver of a critical operating condition, such as a low battery pack level, via a change in pedal resistance. The change in pedal resistance is achieved by preloading one of the springs in the accelerator pedal's spring assembly. The spring assembly uses two springs exhibiting different spring force to achieve distinguishable first and second pedal stroke stages.

Abstract: A dual stage accelerator pedal spring assembly is provided that allows the transition point between stroke stages to be set, thereby controlling pedal travel within the first stroke stage, and notifies the driver of a critical operating condition, such as a low battery pack level, via a pedal feedback system. The spring assembly, which uses two springs exhibiting different spring force, allows adjustment of the relative positions of the two springs in order to control the transition point between the first and second pedal stroke stages. The change in pedal resistance used to notify the driver of a change in a monitored vehicle characteristic is achieved by preloading one of the springs in the spring assembly.

Abstract: An accelerator pedal feedback system is provided that utilizes a virtual spring assembly to provide controllable pedal resistance, thereby supplying the driver with a tactile indicator of changes in a monitored vehicle characteristic, such as a low battery pack level.

Abstract: A sealing device for a chamber including at least one rotary member and at least one static member of a jet engine and can contain a lubricating oil droplet suspension. The sealing device includes at least one brush seal that includes juxtaposed strands and is set to ensure sealing between at least one rotary member and at least one stationary member, a mechanism to recover part of the oil suspended within the inner space of the chamber, and a mechanism to deliver the recovered oil. The delivery mechanism is set up to generate a flow of oil along the strands of the brush seal, the oil flow being oriented in the direction of the rotary member. The brush seal thus provides better resistance to coking.

Abstract: A method and a system for lubricating a turbine engine including at least three separate housings each including at least one roller bearing. The method pressurizes the housings through seals, of which two main housings are pressurized at a pressure higher than that of a remaining secondary housing, lubricates a secondary roller bearing only by injecting an oil mist from at least one of the main housings, the oil mist being supplied by a pressure difference between the main housings and the secondary housing, recovers a remainder of the lubrication oil injected into the main housings to supply the same to an oil tank, and supplies the air/oil mixture from the secondary housing to an oil separator.

Abstract: A device for discharging oil from an oil chamber located in a downstream part of a gas turbine engine, the device including: a mechanism discharging at least part of the oil contained in the chamber to exterior of the engine; and a drive mechanism for driving the oil, which allows passage of an air flow that assists in driving the discharge of the oil to the exterior of the engine. The drive mechanism includes: a ventilation port in the downstream part of the engine, such that the oil passes through the ventilation port; and a guide element arranged such that, after the oil has passed through the ventilation port, the oil is directed towards a downstream bleed area of the low-pressure turbine. A turbomachine can include such an oil discharge device.
