    摘要: A reduction gear for producing and feeding the rotation of a low pressure turbine driven by a combustion gas generated in a combustor to an output shaft is received in a central opening of a rotary type heat exchanger which is disposed so as to be perpendicular to a turbine shaft at a rear portion of a body housing of a gas turbine engine. As a result, not only the engine can be made small but also the output can be produced at to the opposite side of the heat exchanger. The combustor and a collector housing for collecting combustion gas are disposed on diametrical opposite sides in a transverse cross section of the body housing whereby an internal space of the body housing is effectively utilized and an axial dimension of the engine is shortened. Since the compressed air is supplied to the heat exchanger through peripheral walls of the body housing having a double construction, prevention of heat radiation from the body housing and effective utilization of an internal space of the body housing are realized.

    摘要: A turbocharger comprises a compressor housing, a turbine housing, and a central housing with a shaft rotatably supported therein. The shaft supports on its respective opposite ends a compressor wheel and a turbine wheel that are rotatably disposed in the compressor housing and the turbine housing, respectively. The central housing has a large water jacket near the turbine housing and substantially coextensive therewith for storing cooling water to cool bearings which support the shaft. The turbine housing accommodates a shroud including a vane holder on which fixed and movable vanes are alternately supported for directing exhaust gases to the turbine wheel through variable restrictions. The vane holder or base plate has a radially outer flange and an annular boss which position the shroud axially and radially with respect to the central housing.

    摘要: The boost pressure of a blower such as a turbocharger or a supercharger which is driven by the exhaust gas or the power output from an engine is controlled under closed-loop control when the boost pressure is in a steady state, and under open-loop control when the boost pressure is in a transient state. When the boost pressure is in the transient state, the open-loop control which may be map control is carried out for relatively good accuracy and high stability. When the boost pressure is in the steady state, the closed-loop control, i.e., highly accurate feedback control, is effected. Therefore, an improved response and stability can be achieved in boost pressure control.
