摘要： PROBLEM TO BE SOLVED: To suppress progress of wear caused by collision between a seal ring and a wall when a valve is closed as well as progress of wear caused by sliding friction between the seal ring and the wall after collision, in a valve device in which the seal ring is attached to the peripheral edge of a valve body.SOLUTION: In a valve device 1, a projection 33 is provided on a wall 15, and the projection 33 is so provided that a seal ring 5 can slide on the seal ring and cause a tension over the entire rotational angle. Consequently, the seal ring 5 can slide on the projection 33 and is rotated while expansion is being suppressed, without directly sliding on the wall 15. Thus, the collision between the wall 15 and the seal ring 5 will not occur. Although there is a sliding friction between the seal ring 5 and the projection 33, a sliding surface is limited to the inner peripheral edge of the projection 33. As a result, the progress of wear at the seal ring 5 and the wall 15 is significantly suppressed.
摘要翻译：要解决的问题：为了抑制当阀关闭时由密封环和壁之间的碰撞引起的磨损进程以及碰撞后密封环与壁之间的滑动摩擦引起的磨损进展，在阀装置，其中密封环附接到阀体的周缘。解决方案：在阀装置1中，突起33设置在壁15上，并且突起33设置成使得密封环5能够在密封环上滑动并在整个旋转角度上产生张力。因此，密封环5可以在突起33上滑动，并且在膨胀被抑制的同时被旋转，而不会直接在壁15上滑动。因此，壁15和密封环5之间的碰撞将不会发生。尽管在密封环5和突起33之间存在滑动摩擦力，但是滑动表面限制在凸起33的内周边缘。结果，密封环5和壁15的磨损进展显着抑制。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a low pressure EGR device enabling the coexistence of the suppression of the deterioration of fuel economy and the return of a large amount of EGR gas to a suction side by throttling the inside of an exhaust passage by an exhaust gas throttle valve. SOLUTION: A divergent housing 8 is connected to an outlet of an outlet side side-case 7 of a DPF 2. In the divergent housing 8, an EGR gas inlet 5a is formed at a position where a passage area increases. A "De Laval pipe" is formed of the "outlet side side-case 7 (area in which the passage area is reduced) and the "divergent housing 8 (area in which the passage area is increased)". Since the flow velocity of the exhaust gas in the divergent housing 8 is increased, a large amount of EGR gas can be guided to a low pressure EGR flow passage 5 through the EGR gas inlet 5a. Even if the diameter-increased portion of the divergent housing 8 is throttled by the exhaust gas throttle valve 6, the effective passage area of the exhaust passage 3 in the throttled state can be largely secured, and the deterioration of fuel economy can be avoided by preventing defective exhaustion.

摘要： PROBLEM TO BE SOLVED: To provide higher reliability against conduction between a terminal 3 and a wiring 4 by contacting the terminal 3 protruding from a TCU 2 and the wiring 4 installed on the surface of a printed circuit board 5 at two positions. SOLUTION: In a terminal connecting device 1, the wiring 4 is printed so as to straddle over a hole 9 on the printed circuit board 5. Then, the terminal 3 contacts positions 14, 15 and conducts the wiring 4 by a tip part 11 being bent and entering the hole 9. Here, since a spring constant of the tip part 11 is smaller than that of a base part 10, a restoring force of the terminal 3 is smaller at the tip part 11 than the base part 10 at the tip part 11. Moreover, directions of the restoring force of the base part 10 and the tip part 11 of the terminal 3 become to have reverse directions. Accordingly, the restoring force of the base part 10 exceeds that of the tip part 11, and the base part 10 abuts on a position 15 strongly. Since this increases the reliability against the contact between the position 15 and the base part 10, the reliability against the two position contact becomes higher. Accordingly, the conduction reliability between the terminal 3 and the wiring 4 becomes higher. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：通过使从TCU 2突出的端子3和安装在印刷电路板5的表面上的布线4接触两个位置，来提供更高的可靠性，以抵抗端子3和布线4之间的导通。解决方案：在端子连接装置1中，布线4被印刷成跨越印刷电路板5上的孔9。然后，端子3接触位置14,15，并通过尖端传导布线4 部分11弯曲并进入孔9.这里，由于尖端部11的弹簧常数小于基部10的弹簧常数，所以端子3的恢复力在末端部11处比基部10更小此外，基座部10和端子3的前端部11的恢复力的方向成为相反的方向。因此，基部10的恢复力超过顶端部11的恢复力，基部10牢固地抵接在位置15。由于这增加了抵抗位置15与基部10之间的接触的可靠性，所以针对两位置接触的可靠性变高。因此，端子3和布线4之间的导通可靠性变高。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an intake air flow rate adjusting device for an internal combustion engine, capable of preventing malfunction in a heating process and an evacuation process for thermosetting material, in structure that a body driving a valve element in an opening/closing direction is fixed to a housing by thermosetting material. SOLUTION: The housing 10 is provided with a projecting part 16 forming the opening periphery of a cylindrical hole 15 facing to a storage recessed part 12 and also projecting into the storage recessed part 12. With a metallic cap 60 fitted around/press-fitted into the projecting part 16 of the housing 10, an ISCV (idle speed control valve) 40 is fixed to the housing 10 by filling, heating, and hardening potting material P made of thermosetting material to cover a fitting part. Resin being material for the housing 10 has larger linear expansion coefficient than metal being material for the metallic cap 60. Therefore in a heat hardening process, a press-fitted state of the metallic cap 60 and the projecting part 16 is kept, and displacement of the ISCV 40 and leakage of potting material P can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent the failure of a rotary valve 3 and the valve lock, and to make valve leakage amount in an idling operation approximately zero. SOLUTION: When an engine is stopped, the rotary valve 3 is moved to a valve opening side in the radial direction of a rotor shaft 2 by energizing force of a spring acting on a bearing part 23 of the rotary valve 3, thus a clearance between a valve housing 1 and the rotary valve 3 is widened to the maximum, and foreign matters are prevented from being caught in the clearance during engine stop. In the idling operation, the suction force in the arrow direction in a figure, generated when a suction pipe negative pressure is higher than a specific value, is stronger than the energizing force of the spring, thus the rotary valve 3 is moved to a valve closing side in the radial direction of the rotor shaft 2 by the suction force in the arrow direction in the figure, acting on a seat part 21 of the rotary valve 3, the clearance is narrowed to the minimum, and the valve leakage amount in the idling operation becomes approximately zero.

摘要： PROBLEM TO BE SOLVED: To minimize a driving load of an actuator 3, regardless of a valve opening state or a valve closing state of first and second spool valves 5 and 6, and regardless of radiator flow pressure or bypass flow pressure. SOLUTION: Pressure (P1 = P2) on both end sides in the axial direction of the first spool valve 5 becomes illustrated vertically same water pressure and is uniformized, by forming a first pressure adjusting passage 61 penetrating in the axial direction of the first spool valve 5 of a cooling water flow control valve 2. Pressure (P3 = P4) on both end sides in the axial direction of the second spool valve 6 becomes illustrated laterally same water pressure and is uniformized, by forming a second pressure adjusting passage 62 penetrating in the axial direction of the second spool valve 6 of the cooling water flow control valve 2. Thus, since a pressure load can be canceled when the first and second spool valves 5 and 6 move in its axial direction, the driving load of the actuator 3 can be reduced. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To precisely detect pressure in a suction pipe of an engine without being influenced by turbulence of air stream caused in accordance with large or small opening of a throttle valve 3.
SOLUTION: A cross sectional shape of a throttle body 4 is a partial double pipe structure arranging a bore external pipe 35 on an outside diameter side of a bore internal pipe 34 on the downstream side more than a rotation axis of the throttle valve 3. A cylindrical space 37 communicating with a combustion chamber of the engine in parallel for a suction air flow passage 31 storing the throttle valve 3 openably and closably is formed between the bore internal pipe 34 and the bore external pipe 35 of the throttle body 4. Consequently, since air pressure introduced through a pressure introduction passage 8 from the cylindrical space 37 capable of reducing pressure fluctuation as much as possible can be measured by a pressure sensor without being influenced by turbulence of air stream caused in accordance with large or small opening of the throttle valve 3, suction pipe pressure can be precisely detected.

摘要： PROBLEM TO BE SOLVED: To provide an intake air throttling device for an internal combustion engine capable of preventing a butterfly valve 6 from rotating when the outer peripheral part of the disk-like part 47 of the butterfly valve 6 is mechanically brought into contact with the inner diameter surface of a throttle body 1. SOLUTION: An offset valve is adopted as the butterfly valve 6, and the butterfly valve is disposed so that the disk-like part 47 of the butterfly valve 6 is tilted by a prescribed tilt angle relative to a line perpendicular to the center axis of an intake air passage 10 when the outer peripheral part of the butterfly valve 6 is mechanically brought into contact with the inner diameter surface of a throttle body 1. Thus, since the position of the butterfly valve 6 relative to the inner diameter surface of the throttle body 1 can be adjusted by mechanical touch in assembling the valve, the assembling operation of a throttle shaft 4 with the butterfly valve 6 can be performed in such a state that a clearance formed between the inner diameter surface of the throttle body 1 and the outer peripheral part of the butterfly valve 6 is minimum.
