Abstract: A centrifugal blower includes a box, a filter, an impeller, a scroll casing, a bell mouth, a partition wall, and a separation tube. The scroll casing defines an air passage gradually increasing from a nose portion in a circumferential direction. The partition wall divides the air passage into an upper passage and a lower passage. The separation tube includes an air introducing plate to partially cover the impeller and defining an air inlet portion and a tubular portion that extends from the air inlet portion through the impeller. On a virtual plane parallel to a rotational axis of the impeller, an outer edge of the air introducing plate extends and a passage between the filter and the upper passage is divided by the separation tube into a first passage cross-section closer to the nose portion and a second passage cross-section that is smaller than the first passage cross-section.

Abstract: A centrifugal blower includes an outer rotor, and a turbo fan. The turbo fan includes blades, an other end plate, and a cylinder portion. The cylinder portion is located inside the other end plate, and is fixed to the outer rotor. A surface of the outer rotor configures a rotor guide surface that guides an air flow toward a channel provided between adjacent blades. Each blade has a leading edge side portion located radially inside the cylinder portion. An outer end portion of the rotor guide surface in the radial direction is located at the same position in the axial direction as a one side cylinder end portion of the cylinder portion in the axial direction, in a state where a rotor contact portion of the outer rotor and a blade contact portion of the leading edge side portion are in contact with each other.

Abstract: A centrifugal blower device has a turbo fan unit and a casing. The casing includes a first casing member and a second casing member. One of the first casing member and the second casing member includes a first step portion having a first surface, a second step portion having a second surface, and a third step portion having a third surface. Each of the first surface, the second surface and the third surface forms a part of an outer surface of the one of the casing members and has a position different from one another in an axial direction. The second surface is located at a position closer than the first surface to the other one of the first casing member and the second casing member. The third surface is located at a position closer than the second surface to the other one of the casing members.

Abstract: A centrifugal blower includes a centrifugal fan and a case that houses the centrifugal fan. A blade of the centrifugal fan has an intake side edge portion extending from a shroud inward in a radial direction. The intake side edge portion has a negative pressure side inclined portion inclined to a negative pressure surface side of the blade with respect to an axial direction. The negative pressure side inclined portion has an inclination length in the axial direction, and the inclination length is larger in a reverse flow portion of the intake side edge portion close to the shroud than in a radially innermost portion of the intake side edge portion located at an innermost side in the radial direction.

Abstract: A power transmission system transmits power from a drive shaft of an internal combustion engine to a first and a second auxiliary device through a belt. An auto-tensioner extends or contracts to change the tension of the belt. A controller rotates the first auxiliary device in a reverse direction to loosen the belt to cause the auto-tensioner to extend to increase the tension of the belt and calculates a reversing timing when the drive shaft will be reversed as a result of increasing of the tension of the belt. The controller inhibits the tensioner body from contracting immediately before or when the reversing time is reached to keep the tension of the belt at an increased degree, thereby eliminating the slippage of the belt on each pulley without having to finely control the operation of the first auxiliary device when the internal combustion engine is started.
Abstract translation: 动力传动系统通过皮带将动力从内燃机的驱动轴传递到第一和第二辅助装置。 自动张紧器延伸或收缩以改变皮带的张力。 控制器使第一辅助装置沿相反方向旋转以松开皮带，使自动张紧器延伸以增加皮带的张力，并计算当驱动轴由于张力增加而反转时的换向时机 的皮带。 控制器在紧急反转时间之前或之后阻止张紧器体收缩，以保持皮带的张力增加，从而消除皮带在每个滑轮上的滑动，而不必精细地控制第一辅助件的操作 内燃机启动时的装置。

Abstract: A fan main body member of a turbofan has multiple blades disposed around a fan axial center, a shroud ring coupled to each of the blades, and a fan hub portion coupled to each of the blades on a side opposite from the shroud ring. An other end side plate of the turbofan is joined to each of the other side blade end portions of the blade in a state of being fitted to the radially outer side of the fan hub portion. A fitting gap between the other end side plate and the fan hub portion is formed such that an outflow velocity of air when air passes through the fitting gap and outflows is reduced as compared to when air passes through a virtual reference gap that corresponds to the fitting gap and outflows.
