Abstract: A lash adjuster is provided which can maintain stable valve lift. An adjuster screw is mounted into a threaded hole formed in the bottom of the end plate of a lifter body. An elastic member is mounted in the threaded hole to bias the adjuster screw axially downwardly. The female threads of the threaded hole and the male threads of the adjuster screw are serration-shaped. A plurality of axial grooves are formed in the inner periphery of the threaded hole to circumferentially divide the female threads into many separate portions, and satin-finished rough surfaces are formed on the pressure flanks of the male threads by shot-peening to quickly expel oil film disposed between the opposed pressure flanks, thereby stabilizing the valve lift.

Abstract: In a rotary electric machine using a sintered oil-impregnated bearing, oil that oozes out from the sintered oil-impregnated bearing is prevented from attaching onto a brush. In a stay part providing a brush holder stay, there is formed a through hole into which the sintered oil-impregnated bearing is fitted. A pair of holder portions that each accommodate therein a brush are formed to diametrically face each other. A terminal-fixing portion is formed on one side of each holder portion. A prescribed gap exists between the one side position and the terminal-fixing portion. By closing the inner-radial end of the gap by an end wall, a first oil pool is formed. Thus, the first oil pool is structured as an oil pool on an oil path of any oozed oil flowing from the through hole toward the outer radial side of the holder portion to prevent the oil from entering the holder portion.

Abstract: A phosphorus-copper brazing material formed of a phosphorus-copper brazing alloy which can easily be cold-worked into a thin sheet, a brazing sheet having a brazing layer of the phosphorus-copper brazing alloy, and a flow path structure for heat exchangers constructed by brazing with the alloy, are such that the phosphorus-copper brazing material includes a phosphorus-copper brazing alloy containing Cu as a major component and phosphorus of not less than about 2.0 mass % to not more than about 3.2 mass %. The brazing sheet includes a metal sheet, and a brazing material layer that is integral with the metal sheet on at least one side of the metal sheet, the brazing material layer being formed of the phosphorus-copper brazing alloy. The metal sheet may be formed of copper or a copper alloy containing Cu as a major component.

Abstract: A lash adjuster is provided which can keep a constant valve lifting amount. An adjust screw is brought into threaded engagement in a threaded hole formed in the bottom surface of an end plate of a lifter body. The adjust screw is biased in the axial direction by an elastic member. The threads of female threads of the threaded hole and the male threads on the adjust screw are serrated. The surface roughness of the pressure flanks of the serrated threads is set to 0.4 or over to prevent the adjust screw from retracting while turning when push-in loads are applied to the adjust screw from the valve stem, thereby stabilizing the valve lifting amount. Also, a slide member is mounted between the adjust screw and the valve stem and a retaining device is provided to prevent the slide member from turning relative to the nut member while supporting it so as to be movable in the axial direction.

Abstract: A bearing apparatus for a vehicle driving wheel has a pre-loading mechanism formed in the serration fitted portion between the stem portion of the outer joint member and the wheel hub. A fastening member combines the wheel hub and the outer joint member. A releasing member, adapted to be arranged on the wheel hub, enables removal of the fastening mechanism.

Each header tank unit further includes an intermediate plate, which defines a plurality of communication holes therethrough. Each communication hole communicates between a corresponding one of the tubes and a corresponding one of chambers defined by the fluid conduits of the header tank unit such that each tube is spaced apart from the corresponding one of the chambers.

Abstract: This invention provides a chain tensioner that is compact, excellent in operation, easy to maintain and handle and low in manufacturing cost. This chain tensioner has a tubular housing 1 having a bottom, a plunger 3 installed in the inner periphery 1a of the housing so as to smoothly slide inside the housing, a return spring 5 providing the plunger 3 with a force pushing outward, a plurality of latching grooves 33a-33d formed on the outer periphery of the plunger 3, a resister ring 7 capable of locking in the latching grooves, and a check valve 6 that is mounted on the bottom of the housing inner periphery 1a, provides the housing inner periphery 1a with operating oil and prevents its reverse flow. The range of backward movement of the plunger 3 is limited by mating the resister ring 7 locked in the latching grooves 33a-33d with a first stopper 21 formed on the housing inner periphery 1a.

Abstract: In a tube for a heat exchanger, a plurality of passages is defined. The passages are arranged in rows parallel to a major axis of the tube cross-section and staggered. When the tube is extruded, an extrusion material can flow around dies for forming passages and easily merge between the dies. Since walls between adjacent passages can be easily formed, formability of the tube is improved.

Abstract: A heat exchanger includes a first tube in which water flows and a second tube in which refrigerant flows, and performs heat exchange between water and refrigerant. The first tube and the second tube are bonded to each other by brazing at joint surfaces thereof such that water flow crosses refrigerant flow perpendicularly. The joint surface of the first tube is divided into several surface regions by grooves. Accordingly, the joint surface of the first tube can be brazed to the joint surface of the second tube uniformly.

Abstract: Plural heat-exchanging plates for forming an evaporator have plural projection ribs. The projection ribs protrude toward outside of each pair of the heat-exchanging plates to form therein refrigerant passages through which refrigerant flows, and to form an air passage between adjacent pairs of the heat-exchanging plates. The projection ribs protrude from flat surfaces of the heat-exchanging plates toward the air passage to disturb a straight flow of air. The projection ribs are provided in each of the heat-exchanging plates to have a protrusion pitch (P1) between adjacent two, and the protrusion pitch is set in a range of 2-20 mm. Further, each of the heat-exchanging plates has a thickness of in a range of 0.1-0.35 mm, and a passage pitch (P2) between the refrigerant passages is in a range of 1.4-3.9 mm. Thus, in the evaporator formed by only using the plural heat-exchanging plates, a sufficient heat-exchanging performance can be obtained.

Abstract: An installation structure allows easy installation of vibration-proofing members in an electric motor, which avoid resonance due to vibration of an engine, without increasing the number of components. A bottom wall of an installation hole for receiving the electric motor is spaced from a bottom wall of a yoke. Also, flexible tabs are formed on the bottom wall of the yoke. In this arrangement, the electric motor is installed in the installation hole in a manner such that the flexible tabs are pressed into contact with a step portion arranged on the bottom wall of the installation hole.

Abstract: A tube for a heat exchanger has notch portions at a longitudinal direction end portion to be inserted into a header tank. Further, several passage holes are provided in the tube to extend in a longitudinal direction of the tube in which refrigerant flows. The notch portions are formed by cutting parts of the tube to be defined by cut surfaces. The passage holes are not provided at portions corresponding to the cut surfaces. Therefore, the passage holes are securely prevented from being crushed and cut when the notch portions are formed by cutting. As a result, joining failure between the tube and the header tank can be prevented.
