摘要： PROBLEM TO BE SOLVED: To set output characteristics so as not to be dispersed for each product in a sensor output setting method of a valve angle sensor.SOLUTION: A sensor output setting method includes a storage step for storing an actual measured value of a valve angle in a mechanism full open position as an actual full open valve angle, a first setting step for setting an output value in a mechanism full close position, and a second setting step for setting an output value in the actual full open valve angle. Thus, output characteristics can be set to ideal characteristics without being influenced by dispersion of an actual angle in the mechanism full open position. Accordingly, reliability of the output value from a valve angle sensor is improved, and a valve opening can be accurately controlled.

摘要： PROBLEM TO BE SOLVED: To provide a valve unit that can prevent the adhesion of a shaft of an intake throttle valve and a bearing.SOLUTION: A valve housing 20 has a shaft penetration part 20b at which a penetration hole 20a for making the shaft 22 penetrate it is formed, and the shaft penetration part 20b is formed so as to protrude toward the inside of an air intake passage 2. A cup-shaped part 23c formed with a cup-shaped hollow part at one side in the radial direction which is fixed to the shaft 22 is formed at the intake throttle valve 23, and the cup-shaped part 23c is arranged so as to surround an outer periphery of the shaft penetration part 20b which protrudes toward the inside of the air intake passage 2. By this arrangement, a passage in which part of a low-pressure ERG gas which reflows to the air intake passage 2 from a low-pressure EGR passage 18 intrudes into the bearing which is a sliding gap between the bearing 21 and the shaft 22 can be formed into a labyrinth structure, so that a particulate substance contained in the low-pressure EGR gas hardly intrudes into the bearing, and thereby the adhesion of the bearing 21 and the shaft 22 can be prevented.

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 increase the EGR amount when an EGR valve is full opened by mounting a magnetic rotation angle sensor and a magnetic spring means and supporting an EGR valve element in a cantilever-like form.

摘要：【課題】最小開度時に弁体が流体通路の流線方向に対して傾斜するバルブ装置において、最小開度時に流速勾配によってシャフトに作用する回動トルクをキャンセルさせる。【解決手段】吸気絞り弁1のバルブ4は、軸方向から見て上流弁部4aと下流弁部4bの傾斜角が異なる略Z字形に設けられて、上流弁部4aの面積S1より下流弁部4bの面積S2が大きく設けられる。これにより、上流弁部4aの受動トルク(S1?P1)と、下流弁部4bの受動トルク(S2?P2)とを略等しくすることができ、流速勾配によってシャフト3に作用する回動トルクTを略0にできる。このため、最小開度状態から弁体4を開弁させる際や、最小開度付近で弁体4をコントロールする際の回動負荷を低減することができ、電動アクチュエータやトルク伝達範囲の負荷を低減できる。【選択図】図1

摘要： PROBLEM TO BE SOLVED: To solve the problem of reduction in strength of a resin-molded portion that transfers rotational power from an intermediate gear which rotates driven by motor M to a driving shaft or a cam plate of an RGR valve, namely an output gear body, due to a weld line that occurs around or near metal nuts of an insert member of a conventional insert resin gear wheel.SOLUTION: In an output gear 1, a position of a weld line produced as a result of merging of a molten resin flow skirting around one side of first through third metallic nuts 6 of an insert member and a molten resin flow skirting around the other side of the first through third metallic nuts 6 is cut off with a cut-off portion 94 of an injection molding mold so as to prevent generation of a weld line, contributing to strength losses, at the molten resin merging site. It thus becomes possible to eliminate a strength deficiency of the resin-molded portion 2 of the output gear 1 and also prevent cracks in the resin-molded portion 2.

摘要： PROBLEM TO BE SOLVED: To solve the problem that when a low-pressure EGR adjustment valve and an intake throttle valve are driven by a single electric actuator, since a link device operates the intake throttle valve after enlarging the opening degree of the low-pressure EGR adjustment valve, the opening degree of the low-pressure EGR adjustment valve becomes large when releasing freezing lock and affects EGR control.SOLUTION: In a cam groove 11 of the link device 7, separately from grooves used in normal operation (opening degree keeping cam groove 11a, intake throttling cam groove 11b), a freezing lock releasing cam groove 11c is provided for turning the intake throttle valve 5 by turning the low-pressure EGR adjustment valve 4 in an opposite direction from a fully-closed position θ0. With this, freezing lock of the intake throttle valve 5 can be released while the low-pressure EGR adjustment valve 4 has an opening degree near the fully-closed position. Namely, increase in the opening degree of the low-pressure EGR adjustment valve when releasing the freezing lock can be inhibited and affection to the EGR control can be suppressed small.

摘要： PROBLEM TO BE SOLVED: To provide a high pressure EGR device which can drive both a high pressure EGR adjusting valve 4 and a high pressure EGR cooler switching valve 7 by one electric motor 8 and satisfy both characteristics required by the high pressure EGR adjusting valve 4 and by the high pressure EGR cooler switching valve 7.
SOLUTION: An EGR driving gear 9 of a high pressure EGR adjusting valve 4 is driven by employing an electric motor 8. A cooler driving gear 10 of a high pressure EGR cooler switching valve 7 is driven by the EGR driving gear 9. Only when the high pressure EGR adjusting valve 4 is at its maximum opening, the EGR driving gear 9 and cooler driving gear 10 mesh with each other to force the high pressure EGR cooler switching valve 7 to be switched. When the high pressure EGR adjusting valve 4 is at its another opening different from the maximum opening, an opening of the high pressure EGR adjusting valve 4 only is adjusted by the electric motor 8. Thus, the opening of the high pressure EGR adjusting valve 4 can be arbitrarily adjusted with the high pressure EGR cooler switching valve 7 switched to a hot side or cold side.
