摘要： PROBLEM TO BE SOLVED: To improve abrasion resistance and seizure resistance of sliding parts in a pump in which a tappet moves in a reciprocating manner when a cam ring revolves. SOLUTION: Plate-like sliders 31 to 33 that are movable in a direction X of relative movement of the cam ring 18 and the tappet 202 are interposed between a cam ring sliding surface 181a and a tappet sliding surface 202a. Thus, sliding can occur at a plurality of portions, i.e., between the cam ring 18 and the slider 33, between the adjacent sliders and between the tappet 202 and the slider 31 so that the amount of slide is dispersed. And, the amount of slide at each sliding part is reduced by the dispersion of the amount of slide and the sliding speed at each sliding part is decreased so that the abrasion resistance and the seizure resistance at the sliding part are improved.

摘要翻译：要解决的问题：为了提高当凸轮旋转时挺杆以往复运动的方式移动的泵中的滑动部件的耐磨性和耐咬合性。解决方案：可以在凸轮环滑动面181a和挺杆滑动面202a之间插入能够在凸轮环18和挺杆202的相对运动方向X上移动的板状滑块31〜33。因此，滑动可以在多个部分，即凸轮环18和滑块33之间，相邻的滑块之间以及挺杆202和滑块31之间发生，从而使滑块的数量分散。并且，滑动部分的滑动量通过滑动量的分散而减小，并且每个滑动部分的滑动速度减小，从而提高了滑动部分的耐磨性和抗咬合性。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve unit in which valve body can be easily attached to a shaft even in a structure which instruments hardly reach and which can be hardly visible.SOLUTION: The valve unit is composed of a valve housing 1 having a fluid channel 11 and a butterfly valve 2 for opening and closing the fluid channel 11. In the butterfly valve 2, a valve body 4 for adjusting the opening of the fluid channel 11 is fixedly attached to a shaft 3 arranged crossing the fluid channel 11 by spring force. As measures for fixedly attaching the valve body 4 to the shaft 3, the valve body 4 is formed of a plate-shape elastic body, a generally semicylindrical part 43 is formed by bending the center part of the valve body 4 in a semicylindrical shape and outwardly fitted to the middle part of the shaft 3 exposed to the fluid channel 11, or the valve body 4 is fixed to the shaft 3 using a separated fixed spring.

摘要： PROBLEM TO BE SOLVED: To provide an EGR gas introducing device capable of avoiding any trouble that the rotational balance of an intake compressor is impaired by the deviation of the temperature distribution without any pressure loss in an intake passage.SOLUTION: In an EGR opening part 10, a low-pressure GR flow passage 9 is not projected in an intake passage 8, and the intake passage 8 has no pressure loss. Since EGR gas is cooled with the intake air flowing in an annular recess 11 via a pipe member 12, EGR gas cooled with the pipe member 12 is introduced inside the intake passage 8. Thus, the deviation of the temperature distribution in a mixing area of the intake passage 8 can be suppressed. Further, since the EGR opening part 10 is opened at the center of the annular recess 11, EGR gas is introduced to the center side of the intake passage 8, and flows so that the intake air may surround its peripheral. The contact area of EGR gas with intake air is increased, the mixing property of EGR gas with intake air is enhanced, and the deviation of the temperature distribution of the mixing area can be also suppressed thereby.
摘要翻译：解决问题的方案：提供一种EGR气体导入装置，其能够避免进气压缩机的旋转平衡受到温度分布的偏差而损害的任何问题，而在进气通道中没有任何压力损失。解决方案：在EGR开口部10中，低压GR流路9没有突出在进气通路8中，进气通路8没有压力损失。由于EGR气体被吸入空气经由管构件12在环状凹部11内流动而被冷却，所以用管构件12冷却的EGR气体被引入进气通道8内。因此，在混合区域的温度分布的偏差可以抑制进气通道8。此外，由于EGR开口部10在环状凹部11的中心开口，所以EGR气体被引入到进气通路8的中心侧，并且流动，使得进气可以围绕其周边。 EGR气体与进气的接触面积增加，EGR气体与进气的混合性提高，混合区域的温度分布的偏差也受到抑制。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a low-pressure EGR system that determines a failure of an intake throttle valve using an opening sensor of the low-pressure EGR regulating valve and avoids strength reduction of a mechanical stopper.SOLUTION: After an engine is stopped, the low-pressure EGR regulating valve 5 is rotated to the fully-open side to a limit opening degree θ3 at which movement of a linking device 9 is regulated by the mechanical stopper 10. When an opening degree detected by the low-pressure EGR opening sensor is different from the limit opening degree θ3, it is determined that a failure has occurred. The limit opening degree θ3 by the mechanical stopper 10 is set to an opening degree larger than an EGR amount control opening degree range θ0-θ2. Accordingly, the mechanical stopper 10 regulates the movement of the linking device 9 only when a failure is determined (after the engine stop), and the frequency at which a stress is charged on the mechanical stopper 10 can be reduced. As a result, the strength reduction of the mechanical stopper 10 can be avoided even if it is used for a long term, and the reliability can be improved.
摘要翻译：要解决的问题：提供一种低压EGR系统，其使用低压EGR调节阀的开度传感器来确定进气节流阀的故障，并避免机械止动器的强度降低。解决方案：发动机停止后，低压EGR调节阀5旋转到全开侧，达到通过机械止动件10调节连杆装置9的移动的极限开度θ3。当由低压EGR开度传感器检测出的开度与极限开度θ3不同，判断为发生故障。将机械止动件10的限制开度θ3设定为大于EGR量控制开度θ0-θ2的开度。因此，仅当确定故障（发动机停止之后）时，机械止动件10才调节连接装置9的运动，并且可以减小在机械止动件10上施加应力的频率。结果，即使长期使用也能够避免机械止动件10的强度降低，可靠性提高。版权所有（C）2013，JPO＆INPIT

With this, by making a portion of the gear 3, which requires high strength, from metal and by making a portion, which does not require very high strength, from resin, the gear 3 can be reduced in weight as compared with a case of the entire gear 3 being made from metal. As a result, weight saving can be achieved in the subassembly 1 in which the gear 3 constituting a part of the reduction gears 2 and the cam 5 constituting a part of the link mechanism are integrated.

摘要： PROBLEM TO BE SOLVED: To prevent freezing and fixation of the valve of an EGRV and to prevent the erosion of a bushing.SOLUTION: A plurality of stripe-shape recessed grooves 42, 43 are formed on the surface (both side end faces) of the valve 3 of the EGRV so as to avoid the invasion into the interior of the bearing receiving hole 11 of the housing 1 in particular into the slide clearance between the bushing 21 and the slide part 26. Specifically, the plurality of stripe-shape convex grooves 42 extending straight in a vertical direction perpendicular to the rotational axis direction of the shaft 4 are arranged. Further, a plurality of stripe-shape recessed grooves 43 curvedly extending in an arc shape are arranged so as to bypass the opening end fringe of the fitting groove 41 of the valve 3. Consequently, water drops sticking to the surface of the valve 3 can be discharged to the outside of the valve (interior of the EGR gas channel 9) while preventing water drops sticking to the surface of the valve from coming into the interior of the bearing hole 11 of the housing 1 in particular into the slide clearance between the bushing 21 and the slide part 26.

摘要： PROBLEM TO BE SOLVED: To facilitate the machining of an intake passage formed in a housing by reducing a dimension in the axial direction of an intake throttle valve.SOLUTION: An intake throttle bearing 14 is constituted of three of a ball bearing 55, a metal bush 56 and a seal member 57, and difficult to reduce the dimension in the axial direction. Then, the intake throttle bearing 14 is installed in a cup member 15 arranged separately from the housing 11, and the cup member 15 is fixed to the housing 11 in a state of projecting the cup member 15 in the intake passage 2. Thus, an installation position of the intake throttle bearing 14 can be dislocated to the intake passage 2 side, and the dimension in the axial direction of the intake throttle valve 12 can be reduced. Since there is no need to form "a projection by a part of the housing 11" in the intake passage 2, the machining of the intake passage 2 can be easily performed, and the manufacturing cost of the housing 11 can be suppressed.

解决方案：进气节气门轴承14由滚珠轴承55，金属衬套56和密封构件57中的三个构成，并且难以减小轴向尺寸。然后，将进气节气门轴承14安装在与壳体11分开设置的杯构件15中，并且杯构件15在将杯构件15突出在进气通道2中的状态下固定到壳体11上。因此，进气节气门轴承14的安装位置可以错位到进气通道2侧，并且能够减小进气节流阀12的轴向尺寸。由于不需要在进气通路2中形成“壳体11的一部分的突出部”，因此能够容易地进行进气通路2的加工，能够抑制壳体11的制造成本。版权所有（C）2013，JPO＆INPIT
