Принадлежит: федеральное государственное бюджетное образовательное учреждение высшего образования "Московский политехнический университет" (Московский Политех)

Полезная модель относится к области двигателестроения, а в частности к устройствам ограничения частоты вращения турбогенератора, приводимого в движение за счет энергии отработавших газов двигателя внутреннего сгорания. Устройство ограничения частоты вращения турбогенератора включает в себя блок управления, преобразователь постоянного тока, два датчика линейного напряжения, блок формирования управляющего сигнала, резистор, радиатор воздушного охлаждения. Блок управления подсоединен к соединительному разъему для подключения к общей шине данных сигнальным кабелем CAN. Блок управления работает от электрической сети энергоснабжения, получающей энергию от турбогенератора. Блок управления выполнен с возможностью детектирования неисправности генератора турбогенератора и выпрямителя на основании данных, поступающих с датчиков линейного напряжения и передачи исполнительного сигнала блоку формирования управляющего сигнала на включение резистора в случае превышения значения текущей частоты вращения вала турбогенератора максимально допустимой величины. Блок управления выполнен таким образом, что отслеживает разбалансировку напряжения по фазам при работе турбогенератора по значениям текущего линейного напряжения, получаемым от двух датчиков линейного напряжения, и выставлении статуса ошибки на общей шине данных энергоустановки. Блок формирования управляющего сигнала и резистор включены последовательно в статорную цепь турбогенератора на стороне шины постоянного тока.

Variable geometry turbine

Номер: US20120051882A1
Автор: John Frederick Parker
Принадлежит: Individual

A variable geometry turbine comprising a turbine wheel supported in a housing for rotation about a turbine axis with an annular inlet passageway defined between a radial face of a nozzle ring and a facing wall of the housing. The nozzle ring is movable along the turbine axis to vary the width of the inlet passageway and of vanes that are received in corresponding slots in the facing wall. Each vane major surface such that at a predetermined axial position of the nozzle ring relative to the facing wall the recess is in axial alignment with the slot and affords an exhaust gas leakage path through the inlet passageway. The recess is configured to reduce the efficiency of the turbine at small inlet gaps appropriate to engine braking or exhaust gas heating modes.

Принадлежит: Individual

A positive displacement compressor designed for near isothermal compression. A rotor includes a curved sealing portion that coincides with a in an interior rotor casing wall. Liquid injectors provide cooling liquid. A gate moves within the compression chamber to either make contact with or be proximate to the rotor as it turns. Gate positioning systems position the gate in this manner, taking into account the shape of the rotor. Outlet valves allow for expulsion of liquids and compressed gas. The unique geometry and relationship between the parts provides for efficiencies and higher pressures not previously found in existing compressor designs.

The present invention relates to a Stirling engine in which power is generated using a variation in pressure generated by continuously performing periodical heating and cooling operations when a heat transfer medium is stored in a sealed inner space. The Stirling engine generates power for rotating an output shaft ( 12 ) through the expansion and contraction of the heat transfer medium sealed and received in a space partitioned by a baffle ( 40 ) within an inner space ( 21 ) of a housing ( 20 ). Thus, when compared to the prior art, the Stirling engine of the present invention may be more easily manufactured. Also, the heat transfer medium for generating power may be easily managed, maintained, and repaired. In addition, since the heat circulation structure is simple, the Stirling engine of the present invention can achieve relatively higher thermal efficiency than those of the prior art.

A sliding vane, positive displacement pump is provided which uses a fixed disc configuration wherein a rotor includes a pair of discs affixed to opposite faces of the rotor so as to rotate with the rotor/shaft. Preferably, the discs each have an outer diameter proximate the outer diameter of the rotor and define an outer disc surface which faces radially outwardly towards an opposing, inside surface of the pump head or other casing structure. A dynamic seal is provided along the outside disc diameter which eliminates the formation of slip between end surfaces. The path of fluid traveling from the high pressure pump side near the outlet to the low pressure side of pump near the inlet is controlled with a radial clearance that is defined between the OD of each disc and the ID of the stationary head. This effectively eliminates direct slip paths extending radially across axially-directed end faces

A pneumatic motor includes a cylinder and a rotor disposed in the cylinder. The rotor includes an axle, and main and secondary blades are slidably received in a plurality of main and secondary sliding slots formed on the axle. The secondary blades touch an inner wall of the cylinder to promote torque output when located at angles equal to or smaller than a specific angle from an inlet of the cylinder. On the contrary, the secondary blades are away from the inner wall of the cylinder to reduce friction between the rotor and the cylinder when located at angles larger than the specific angle from the inlet. Thus, revolution speed of the rotor is retained in a tolerant range, and torque output is promoted significantly.
