摘要： An oil film damper of a bearing structure is located between facing surfaces of two bearings. The oil film damper includes two protrusions protruding inward in a radial direction from an inner circumferential surface of a main body portion, an oil guiding passage penetrating through from the protrusion to an outer circumferential surface of the main body portion and guiding a lubricating oil from the outer circumference of the main body portion to the bearing, an inclined surface provided on a side opposite to the adjacent surface adjacent to the bearing in the protrusion and having an inner diameter gradually increasing as the diameter is separate from the adjacent surface in the rotation axis direction of the shaft, and an oil discharge hole provided between the two protrusions of the main body portion and discharging the lubricating oil to an outside from an inside of the main body portion.
摘要翻译：轴承结构的油膜阻尼器位于两个轴承的相对表面之间。油膜阻尼器包括从主体部分的内周面沿径向向内突出的两个凸起，从该突起到该主体部分的外周表面的导油通道，并将润滑油从主体部分的外周到轴承的倾斜表面，倾斜表面设置在与突起中的轴承相邻的相邻表面的一侧上，并且其内径随着直径与旋转轴线中的相邻表面分离而逐渐增加轴的方向，以及设置在主体部的两个突起之间的排油孔，并且将润滑油从主体部的内部排出到外部。

摘要： A centrifugal compressor includes a housing that accommodates a wheel. The housing includes an air intake space formed on an entrance side of the wheel; a flow passage to guide fluid compressed by the wheel to the outside of the housing; a return flow passage opened on each wall surface of the air intake space and the flow passage to circulate a part of the fluid in the flow passage to the air intake space without passing through the wheel; and an introduction portion provided in the air intake space, and having an inner peripheral surface that forms a flow passage to guide the fluid from the outside of the housing to the wheel. A downstream end of the inner peripheral surface in a flowing direction of the fluid is located inside in the radial direction of a shaft than the wall surface of the housing.
摘要翻译：离心压缩机包括容纳车轮的壳体。壳体包括形成在车轮入口侧的进气空间; 用于将由所述轮压缩的流体引导到所述壳体的外部的流动通道; 在所述进气空间的每个壁表面上开口的回流通道和所述流动通道，用于将所述流动通道中的一部分流体循环到所述进气空间，而不穿过所述轮; 以及引导部，其设置在所述进气空间中，并且具有形成将所述流体从所述壳体的外部引导到所述车轮的流路的内周面。内周面的流体的流动方向的下游端位于比壳体的壁面更靠轴的径向内侧。

摘要： A turbocharger includes an open-and-close mechanism which opens and closes a circulation hole through which an exhaust gas flows into a turbine housing or the exhaust gas flows out of the turbine housing. The open-and-close mechanism includes: a valve; and an attachment plate one end of which is fixed to the valve, and the other end of which is provided with an insertion hole through which a stem turnably supported by the turbine housing is inserted, and an exposure hole which communicates with the insertion hole to expose part of an outer peripheral surface of the stem. The diameter of the insertion hole is gradually smaller in a direction of insertion of the stem. The stem includes a tapered portion whose diameter is gradually smaller toward its tip end in the direction of insertion into the insertion hole.
摘要翻译：涡轮增压器包括打开和关闭循环孔的打开和关闭机构，废气通过该循环孔流入涡轮机壳体或废气流出涡轮壳体。开闭机构包括：阀门; 以及安装板，其一端固定在阀上，另一端设有插入孔，通过该插入孔插入由涡轮壳体可转动地支撑的杆，以及与插入孔连通的曝光孔露出杆的外周表面的一部分。插入孔的直径在杆的插入方向上逐渐变小。该杆包括锥形部分，其直径在插入插入孔的方向上朝向其末端逐渐变小。

摘要： In a waste gate valve, a coil spring being expandable and contractible in the axial direction of a valve shaft is provided between a washer and an attachment tongue in an axial direction of a valve shaft of a valve. The coil spring is made of a heat-resistant alloy or a ceramic. An annular guard wall is formed on a front surface of the attachment tongue by counter boring in such a way as to surround the coil spring.
