摘要： An opening of the variable nozzle of the exhaust turbine supercharger is set to and maintained at the maximum value in the constant operating state when the load is not more than a prespecified load level. The opening is gradually made smaller, when the load is not less than the specified load level, as the load becomes greater. When the load shifts from the high load region to the low load region, the variable nozzle is mere closed or maintained at the original opening, and when the operating state get close to the surging limit, the variable nozzle is more opened. When shifting from the low load region to the high load region, or when sifting from low speed to high speed, the variable nozzle is opened mace, and then closed to return to the constant operating state.
摘要翻译：当负载不大于预定负载水平时，排气涡轮增压器的可变喷嘴的开口被设定为并保持在恒定运行状态下的最大值。随着负荷变大，当负载不小于规定的负载水平时，开口逐渐变小。当负载从高负载区域向低负载区域移动时，可变喷嘴仅被封闭或保持在原始开口处，并且当操作状态接近浪涌极限时，可变喷嘴更开放。当从低负载区域转移到高负载区域时，或者从低速到高速时筛选，可变喷嘴打开，然后关闭以返回到恒定运行状态。

摘要： There is provided a turbocharger whose constitution is compact, in which exhaust interference seldom occurs, and which can be applied also to an EGR type engine. In the turbocharger, an introduction part of an exhaust inflow passage possesses a partition part dividing a range from an inlet to a predetermined position in a downstream of the inlet into two exhaust inflow passages, a throttle part, whose sectional area becomes gradually small, from the inlet to a position where the partition part ceases, a joining part where exhaust gases passing through the left and right exhaust inflow passages are joined, and a diffuser part, whose sectional area becomes gradually large, from the joining part to a tongue part.

摘要： A turbocharger as a turbo machine includes: a compressor impeller (13) having a projected portion (19) at a center of a rear surface; a drive shaft (15) connected to a bottomed coupling hole (20) provided in the projected portion (19) of the compressor impeller (13) through interference fit only; and a sleeve (30) with a cylindrical portion (33) connected to the outer peripheral portion of the projected portion (19) of the compressor impeller (13) by fitting only. The sleeve (30) is formed of a material whose coefficient of linear expansion is smaller than that of the compressor impeller (13). Accordingly, even when the coupling hole (20) in the projected portion (19) undergoes thermal expansion and the diameter of the coupling hole (20) increases, a connection between the drive shaft (15) and the coupling hole (20) can be prevented from being loosened since the radial increase thereof is suppressed by the cylindrical portion (33). Thus, the state of the connection thereof can be well maintained.

摘要： One of the swing shafts 32 of the nozzle vanes 31 is selected so as to operate as swing drive shaft 33 that projects to the outside. As the swing drive shaft 33 is driven to revolve, all the nozzle vanes 31 are driven to turn by a same angle by way of the driving lever 21 and the coupling ring 18 linked to it. Therefore, it is only the swing drive shaft 33 that projects to the outside, the projecting part can be sealed in a simple and reliable manner to improve the sealing effect and the durability of the variable geometry turbocharger. Additionally, since the rotary motion of the swing drive shaft 33 is directly used to driven the nozzle vanes 31 to swing, the mechanism for transmitting the driving force is simplified.

摘要： A turbo-supercharging system for an internal combustion engine of a vehicle having an air brake system wherein compressed air is preferentially supplied to the air brake system and surplus air is used for supercharging the engine. The system includes an air compressor driven by the engine, an air reservoir tank for storing compressed air therein and supplying it to a turbine of a turbo-supercharger when required, and a solenoid-operated valve disposed in a conduit interconnecting the air tank and the air compressor. The solenoid-operated valve is normally held in its block position and adapted to be changed over to its communication position when air pressure in the air brake system exceeds a predetermined value.
