摘要： PROBLEM TO BE SOLVED: To provide a ball bearing for flow control valve provided in an intake and exhaust systems of an engine, in which sealing ability is enhanced for both positive and negative pressures so that no separate sealing means is required.SOLUTION: A seal member 6 is provided on one end of a bearing 1, and a seal member 7 on the other end of the bearing 1. The seal member 6, including a metal core 10 and an elastic body 11, is fixed to an outer ring 3 so that an outside lip part 13A and an inside lip part 13B contact an outer peripheral surface 2A of an inner ring 2. When a positive pressure acts on the outside of the seal member 6, the pressure presses the outside lip part 13A against the outer peripheral surface 2A of the inner ring 2, such that air tightness of the seal member 6 is maintained. When a negative pressure acts on the outside of the seal member 6, a differential pressure between the outside and inside of the seal member 6 presses the inside lip part 13B against the outer peripheral surface 2A of the inner ring 2, such that air tightness of the seal member 6 is maintained. Thus, sealing ability can be enhanced for positive and negative pressures, which allows no separate sealing means to be required.
摘要翻译：要解决的问题：提供一种设置在发动机的进气和排气系统中的流量控制阀的球轴承，其中正压和负压两者的密封能力增强，从而不需要单独的密封装置。解决方案：密封件构件6设置在轴承1的一端和轴承1的另一端上的密封构件7.包括金属芯10和弹性体11的密封构件6固定到外圈3上外唇部13A和内唇部13B接触内圈2的外周面2A。当正压作用在密封构件6的外侧时，压力将外唇部13A压靠外周内圈2的表面2A，从而保持密封构件6的气密性。当负压作用在密封构件6的外侧时，密封构件6的外侧和内侧之间的压差将内侧唇部13B压靠在内圈2的外周面2A上，使得气密性保持密封构件6。因此，可以提高正压和负压的密封能力，这不需要单独的密封装置。

摘要： PROBLEM TO BE SOLVED: To solve a problem that, since a conventional EGR control valve employs an expensive PTFE seal as condensed-water intrusion prevention means for a bearing, the number of part items and man-hours become large, thus causing a cost increase.SOLUTION: An EGR control valve has at least one or more radial holes 71 for leveling a pressure difference between an A-point and a B-point around an output shaft 5 at a first protrusive shaft part 41 of the output shaft 5 which forms a clearance part 62 between a throttle wall 65 of a hosing 4 and itself, or at a large-diameter shaft part 43. By this constitution, the pressure difference in a shaft circumferential direction at the clearance part 62 formed between an internal peripheral of the throttle wall 65 of the housing 4 and an external periphery of the first protrusive shaft part 41 of the output shaft 5 is eliminated. As a result, even if the expensive PTFE seal is abolished, condensed water does not intruded into a bearing hole 61 from passage holes 22, 23 of the housing 4.

摘要： PROBLEM TO BE SOLVED: To prevent damage to a housing 3 when press-fitting a fitting ring of a resin seal 5, in a valve device preventing leakage around a rotary shaft 9 by the resin seal 5 which is made of fluorine resin as a raw material.SOLUTION: A resin seal 5 which is made of fluorine resin as a raw material is pinched by a metal bearing 19 and a step 29 of a housing 3 in an axial direction, and arranged on the upstream side of all functional components 4 around the shaft with regard to a leakage flow of exhaust gas around a rotary shaft 9. Thereby, the resin seal 5 functions as a shaft seal by coming into sliding contact with an outer peripheral surface of the rotary shaft 9. Also, even without using a fitting ring which was conventionally needed for holding the resin seal 5, the resin seal 5 can be held and brought into sliding contact with the rotary shaft 9. Therefore, press-fitting work of the fitting ring can be eliminated, and damage to the housing 3 can be prevented.

Meanwhile, on the sensor cover 5, a window hole 26 reaching the surface of the test terminal T is formed on the inner circumferential side from the seal groove 19 and the other edge side of the pressure-introducing groove 25 is exposed toward a gear chamber 15 through the window hole 26.

摘要： PROBLEM TO BE SOLVED: To reduce frictional force and a sliding loss between a last gear and a spring.SOLUTION: According to an EGRV, frictional force and a sliding loss between the last gear 5 and a spring 6 can be reduced by bringing a part of a coil end surface of a second coil end part 42 of the spring 6 into partial contact with a spring seat part (a plurality of first to fourth projection ribs) of the last gear 5, and thereby sliding resistance of the spring 6 to the last gear 5 can be reduced. Thereby, since a motor load upon opening and closing operation of the valve of the EGRV can be reduced, power consumption can be suppressed. Also, since hysteresis of the spring 6 can be reduced, opening and closing operation of the valve can be performed with low power consumption. Also, since attitude of the spring 6 upon opening and closing operation of the valve is stabilized, spring characteristics and opening and closing operation of the valve are stabilized.
摘要翻译：要解决的问题：减少最后一个齿轮和弹簧之间的摩擦力和滑动损失。解决方案：根据EGRV，通过使弹簧6的第二线圈端部42的线圈端面的一部分部分地部分地，可以减小最后齿轮5与弹簧6之间的摩擦力和滑动损失与最后的齿轮5的弹簧座部（多个第一至第四突出肋）接触，从而可以减少弹簧6与最后的齿轮5的滑动阻力。因此，由于可以减少EGRV的阀的打开和关闭操作时的电动机负荷，因此可以抑制功率消耗。此外，由于可以减小弹簧6的滞后，能够以低功耗进行阀的打开和关闭操作。此外，由于在阀的打开和关闭操作时弹簧6的姿态稳定，所以阀的弹簧特性和打开和关闭操作稳定。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To restrain deterioration of an emission performance by restraining a temperature rise of a cooled EGR gas in a cooled (cooler) mode. SOLUTION: A partition wall 44 blocking a cooler inlet port 33 and a cooler outlet port 34 extends near a shaft 12 of a four-way switch valve 5 from a cooler mounting face of a coupling part 26, so as to reduce leakage of the EGR gas of a first valve plate-like body 14 (a single side of the four-way switch valve 5) out of two first and second valve plate-like bodies 14, 15 constituting the four-way switch valve 5. Accordingly, the temperature rise of a low-temperature EGR gas (cooled EGR gas) cooled by an EGR cooler and flowing from an EGR gas induction port 32 of the exhaust gas switch valve in the cooled mode can be restrained, so as to restrain deterioration of the emission performance.

摘要： PROBLEM TO BE SOLVED: To suppress heat conduction from a cast iron housing to an aluminum housing without putting a heat insulator between a joining part of the cast iron housing and a joining part of the aluminum housing.
SOLUTION: Rectangular projections 7 and spaces in which the rectangular projection 7 is not arranged (air heat insulation layer) exist between the joining part (joining surface 11) of the cast iron housing 5 and the joining part (opposite surface 12) of the aluminum housing 6 by providing the rectangular projections 7 projecting to the joining surface side of the cast iron housing 5 on the opposite surface 12 of the aluminum housing 6. Consequently, heat of hot EGR gas passing through an EGR gas passage 16 of an EGR gas flow control valve is not easily conducted to the aluminum housing 6 from the joining part of the cast iron housing 5 even if the same is conducted to the joining part of the cast iron housing 5.

摘要： PROBLEM TO BE SOLVED: To provide an EGR device capable of eliminating "a deposition scrape-off control", and preventing sticking of a closed valve even by "a single spring".SOLUTION: An EGR valve 2 includes: water supply means 30 for supplying water to just below a downstream side of a valve 5 (turbulence generation spot), and the water supplied to the downstream side of the valve 5 is raised up and stirred by turbulence generated at the downstream side of the valve 5, and washes away the deposition attached to the valve 5 and a nozzle 15 as waterdrops. Thus the deposition scrap-off control conventionally executed in stopping an engine and the like, can be eliminated, and the sticking of the closed valve can be prevented even when a return spring is a single spring.

摘要： PROBLEM TO BE SOLVED: To stabilize a valve leak flow amount property regardless of an abutment joint assembling position of a seal ring fitted into a seal ring groove of a valve body.SOLUTION: An EGRV (EGR gas control valve) has a structure (axial center offset structure) for offset arranging a nozzle pressedly input hole axial core (CL2) of a valve body 1 by a valve fluctuation quantity caused by the fluctuation a valve shaft generated by the biased load of a return spring to a valve shaft axial core (CL1). Thereby, it is possible to absorb the valve fluctuation quantity caused by the shaft fluctuation generated by the biased load of the return spring. Consequently, the valve body can be located at a center part of an inner diameter face (valve seat face) of a nozzle by the above axial center offset structure even in the case the valve body fluctuates by the valve fluctuating quantity caused by the shaft fluctuation generated by the biased load of the return spring.
