Abstract: The problem to be solved by the present invention lies in making it possible to reduce costs and to reduce the size of an oil pump, without impeding the degree of freedom in chain layout. An oil jet 1 is constructed in order to supply lubricating oil to a tension-side span of a chain C while also causing a tensioning force to act on a slack-side span of the chain C. The oil jet arm 1 is provided with a pivoting-side part 2A, and a tip-end side part 2B which is provided in such a way as to be pivotable about the pivoting-side part 2A and is acted on by a pressing force from a piston 41 of a hydraulic tensioner 4, and an oil ejection hole 22a for ejecting to the outside oil supplied from an oil discharge hole 41a in the piston 41 is formed in the tip-end side part 2B. Oil ejected from the oil ejection hole 22a is supplied to a portion E on the meshing start side with a sprocket 100 on the tension-side span of the chain C.

Abstract: A vane (234) is provided which reduces leakage of gas in a variable geometry turbocharger (210) from the high pressure side of the vane (234) to the low pressure side of the vane (234). The vane (234) can have a channel (330, 430) along a gas bearing surface (325, 425) for reducing the leakage. The channel (330, 430) can be defined at least in part by sideplates (300, 350). The sideplates (300, 350) can be integrally cast with the rest of the vane (234). At least one of the sideplates (300, 350) can have a hole therein for a vane shaft (228) which allows movement of the vane (234) for gas flow control. The sideplates (300, 350) can have edges (301, 351) that conform to the shape of the gas bearing surface (325, 425).

Abstract: A housing (410, 510, 610, 700, 800, 900) for a turbocharger (400, 500, 600) is provided. The housing (410, 510, 610, 700, 800, 900) has an impeller chamber (403, 503, 603), diffuser (450, 550, 650, 750, 850, 950) and scroll (420, 520, 620, 720, 820, 920) in fluid communication with each other. The diffuser (450, 550, 650, 750, 850, 950) can have a curved shape and/or a bend (455) in proximity to a tip (408, 508, 608, 609) of the impeller (405, 505, 605). The curved shape can be defined by one or more radii of curvature (RC, RC1, RC2). The diffuser (450, 550, 650, 750, 850, 950) can extend in a radial direction that is non-orthogonal to the center line of the turbocharger (400, 500, 600). The housing (410, 510, 610, 700, 800, 900) can be for a compressor section of the turbocharger (400, 500, 600).

Abstract: A vane ring assembly which includes a lower vane ring (22), an upper vane ring (30), one or more guide vanes (80) positioned at least partially between the vane rings, and a plurality of spacers (42, or 50) positioned between the lower and upper vane rings for maintaining a distance between the lower and upper vane rings. By using a first set of fasteners (190) to fasten the lower vane ring to the turbine housing, and a second set of fasteners (191) to fasten the lower vane ring to the upper vane ring, the vane ring assembly is effectively decoupled from the turbine housing with regard to differential thermal expansion, and the co-planerism of the vane rings is easier to maintain.

Abstract: [Issue] To allow deviation of a chain to be reliably restricted during travel, and also to allow friction loss to be easily reduced when the chain is operating. [Means of Resolution] A guide plate 4 is disposed on the outermost side in the width direction of a silent chain 1 comprising link plates 2 which are pivotably linked by means of linking pins 3. The guide plate 4 has a pair of pin holes 41 into which the linking pins 3 are inserted, and also has side end parts 42 which are disposed at both ends in the longitudinal direction thereof, and an upper end part 43 and a lower end part 44 which link the side end parts 42 in the longitudinal direction. The upper end part 43 and the lower end part 44 are formed with a tapered transverse section, and become steadily thinner toward the tip end.

Abstract: A turbocharger assembly has a housing (1) in which is formed a turbine volute inlet duct (4) having a butterfly valve (8) disposed therein and a bypass duct (6) which contains a swing valve (15), the valves being operable to control the flow of exhaust gas through each duct. A link member (30) is mounted for rotation about the pivot axis (21) of the swing valve (15) and has an opening in which an actuating pin (20) engages with a tolerance fit so as to non-rotatably connect the swing valve (15) to the link plate (30). The link plate also has an elongated channel (34) along which an actuating pin (13) of the butterfly valve travels upon rotation of the link plate (30) about the pivot axis (21). The elongated channel has a first portion (34a) which extends along an arc centred on the axis of rotation (21) and a second portion (34b) which extends along an arc whose centre is offset from said axis (21).

Abstract: An analog output Hall effect sensor provides a proportional output representative of the angular position of a rotary shift member in a transfer case, transmission or the like. The rotary shift member is driven by a bidirectional electric motor through a speed reducing gear train. A wheel having a single spiral bipolar (N-S) magnetic track rotates with the output of the gear train and the shift member. The analog output Hall effect sensor is proximate the spiral magnetic track and provides an analog (ramp) output proportional to the position of the rotary shift member relative to first and second end points.
