該蠟元件6 3被加熱時,内部的熱膨縮材料會膨脹而逐漸 增加輸出軸6 3 a的突出量,氣閥6 8則和輸出軸6 3 a的突出 量增加同步地使旁通氣路54之開口逐漸縮小,因應於引擎 的溫度上升其可減少自旁通氣路5 4對下流側的進氣通路 5 1 b内供給之空氣量,由此,可自引擎之暖機運轉變換為 通常之怠速運轉。 【發明内容】 (發明所欲解決之問題) 根據以前之怠速空氣控制裝置,蠟元件6 3不僅PTC加熱 器6 2的熱以外亦被環境之溫度所影響。此處,蠟元件6 3 之輸出軸6 3 a的突出特性為適合於引擎之溫度狀態,而對 環境溫度其和輸出軸6 3 a的突出特性之間則會發生差異。 例如,環境溫度在高溫狀態時,輸出軸6 3 a的突出量會 變大而氣閥6 8則會有閉塞旁通氣路5 4的開口之傾向,在 312XP/發明說明書(補件)/94-07/94 ] 09739 1277691 引擎起動時則不能供給充份的空氣。 又,輸出軸63a之突出量會因PTC加熱器62之發熱、躐 元件63之PTC加熱器62之加熱、樣元件63内之熱膨縮材 料的容積變化而變位,而使得輸出軸6 3 a的應答速度變 慢,且使得微小的空氣量控制困難。 本發明之怠速空氣控制裝置為鑑於上述課題而所完成, 其目的為提供一種使驅動氣閥之驅動體在自蠟元件變更為 馬達時,可確實地吸收馬達的輸出軸和氣閥之偏心,對氣 Φ 閥導引孔可使氣閥正確同心地配置。 且其可使用配置在傳統的橫剖面圓形的氣閥導引孔之圓 筒形的氣閥,而具備有和傳統的怠速空氣控制裝置的互換 性。 _ 如此所成之燃料噴射裝置之怠速空氣控制裝置。 (解決問題之手段) 為了達成上述目的,本發明之燃料喷射裝置之怠速空氣 控制裝置為,在穿設於節流體内之進氣通路配置節流闊。When the wax element 63 is heated, the internal heat expansion and contraction material expands to gradually increase the amount of protrusion of the output shaft 63 3 a, and the gas valve 68 causes the side air passage in synchronization with the increase in the amount of protrusion of the output shaft 6 3 a. The opening of 54 is gradually reduced, and the amount of air supplied from the bypass passage 5 to the downstream intake passage 5 1 b can be reduced in response to the temperature rise of the engine, thereby changing from the warm-up operation of the engine to the normal It is running at an idle speed. SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) According to the prior idle air control device, the wax member 63 is affected not only by the heat of the PTC heater 62 but also by the temperature of the environment. Here, the protruding characteristic of the output shaft 633a of the wax member 630 is adapted to the temperature state of the engine, and a difference occurs between the ambient temperature and the outstanding characteristic of the output shaft 63a. For example, when the ambient temperature is at a high temperature, the amount of protrusion of the output shaft 63 3 a becomes large, and the valve 6 8 has a tendency to block the opening of the bypass passage 5 4 , in 312 XP / invention manual (supplement) / 94 -07/94 ] 09739 1277691 Sufficient air cannot be supplied when the engine is started. Further, the amount of protrusion of the output shaft 63a is displaced by the heat generated by the PTC heater 62, the heating of the PTC heater 62 of the 躐 element 63, and the volume change of the heat expansion material in the sample element 63, so that the output shaft 63 The response speed of a is slow, and it is difficult to control the amount of minute air. The idling air control device of the present invention has been made in view of the above problems, and an object of the invention is to provide an eccentricity of an output shaft and a valve of a motor that can reliably absorb a driving body of a driving valve when the wax element is changed to a motor. The gas Φ valve guide hole allows the valve to be properly concentrically configured. Moreover, it is possible to use a cylindrical valve which is disposed in a conventional circular cross-section valve guide hole, and has interchangeability with a conventional idle air control device. _ The idle air control device of the fuel injection device thus formed. (Means for Solving the Problem) In order to achieve the above object, the idle air control device for a fuel injection device according to the present invention has a throttle portion that is disposed in an intake passage that is disposed in a throttle body.

Further, the gas valve and the slider are synchronously moved to the axial direction, and the valve is controlled to open the opening of the bypass passage of the valve guide hole opening. Further, in addition to the first feature described above, the present invention is characterized in that the gas valve is disposed between the stopper portion provided on the outer periphery of the lower end of the slider and the stopper portion at the upper end of the slider. At the same time, the air valve spring disposed on the outer circumference is configured to be pressed toward the locking portion, further between the inner peripheral portion of the air valve and the outer peripheral portion of the slider, and the inner circumference of the outer circumference ring of the air wide Between the portions, a gap larger than the eccentricity of the longitudinal axis of the axial valve guide hole in the longitudinal direction of the motor output shaft is formed.

According to the first aspect of the present invention, when the motor is driven and the motor is rotated in the output direction, the slider is prevented from moving by the rotation of the ring, so that the valve is also moved downward in synchronization with the slider. . Since the air valve is guided to move downward in the guide hole of the air valve, and the air passage in the opening guide hole is closed, the air valve is closed in response to the single direction of the motor. In addition, when the motor output shaft rotates in the maximum direction in one direction, the slider moves in the lowermost direction, and the air valve can be kept in the valve guide hole and the open air passage is fully closed. On the other hand, when the motor output shaft is rotated in the other direction, since the ring is restrained from rotating and moves in the upward direction, the motor output shaft moves in the upward direction in synchronization with the slider. When the air valve moves upward, the air passage is opened beside the opening in the air valve guide hole, and the air valve can be opened according to the amount of rotation in the motor direction. When the motor output shaft rotates to the other side, the slider will be the most Moving in the upward direction, the air valve can be fully opened adjacent to the opening in the air guide hole of the air valve. According to the first feature, the slider is screwed to the output shaft of the motor, and the ring is restrained from rotating, and the movement in the axial direction is allowed, and the air valve and the slider are locked in the axial direction. Therefore, the gas valve and the slider can synchronously move the opening of the bypass air passage which controls the opening in the air valve guide hole in the air valve guide hole. By suppressing the rotation of the slider between the ring and the ring, it is not necessary to use the gas 312XP/invention manual (supplement)/94-07/94109739 shaft pair to the next and at this time, the valve will rotate When the bypass valve of the bypass valve is also moving, the other direction is kept at the most for the hunting circle, and the valve can be set to 10

In this case, the circular valve guide hole of the cross section which is made by the idle speed control means of the prior wax element can be used, and the idle control device of the present invention can be easily mounted on the previous throttle body and made interchangeable. Further, when a single box body is formed with a motor case surrounding the outer circumference of the motor and an insertion tube portion extending downward, when the case is molded outside the case, since the motor output shaft is formed as a reference, the insertion tube portion can be formed. Improve the accuracy of the center of the axial direction of the output shaft and the axial center of the insertion barrel. This is preferable when the air valve is guided concentrically in the valve guide hole. Further, when the box body is integrally formed with the motor case and the insertion tube portion, the number of parts is effectively reduced.

在插入於在節流體5 0之一端5 0 a開口的插入孔5 6内之插 入筒部1 b的外周溝1 f所成之固定構件6,而箱本體1被 固定在節流體5 0上。 根據上述,氣閥4則被配置成在氣闊導引孔5 5内可移 動,該狀態如圖〗所示。 其次說明本發明之怠速空氣控制裝置之作用。 茲說明引擎或環境溫度低時之起動狀態。 引擎被起動操作時,同步的自ECU對馬達Μ被輸出因應 14 312ΧΡ/發明說明書(補件)/94-07/94109739 1277691 於低溫狀態之電氣信號,馬達Μ則依前述信號在單方向以 一定範圍迴轉。該馬達輸出軸Ma在單方向迴轉時,滑件3 則向上方向大大地被拉起,氣閥4也和滑件3同步在氣閥 導引孔55内往上方向大大地被拉起而使旁通氣路54開放。 根據上述,由旁通氣路5 4朝引擎可供給多量的起動用空 氣,在該低溫狀態中可良好地使引擎起動。 又,在上述中,藉馬達輸出軸Ma向單方向迴轉,可將滑 件3往上方向拉起是因為在滑件3的溝3e内插入有固定在 Φ 箱本體1的圈環2之限制突部2 c,而可抑止滑件3的迴轉, 如此所致。 其次,完成前述起動,而實施引擎之暖機運轉時,引擎 之溫度會徐徐上升,ECU則朝馬達Μ輸出因應其溫度上升 之電氣信號。 馬達輸出軸Ma依照前述電氣信號而朝和前述單方向之 反對方向的另一方向迴轉,藉此滑件3可向圖中之下方向 移動,同時,氣閥4也和滑件3同步地使氣閥導引孔5 5 内在下方向移動,而隨著溫度的上升旁通氣路5 4之開口則 逐漸減小。 因此,隨著引擎之暖機運轉同步地向引擎供給之空氣量 則逐漸減少,而不會使引擎有不必要的迴轉數上升,而可 實施引擎良好的暖機運轉。 又,在引擎之暖機運轉完全終了之狀態時,滑件3則變 成被配置在圈環2的最下方位置,而同步地氣閥4也變成 被配置在氣閥導引孔5 5之最下方位置,由此而可使旁通氣 15 312XP/發明說明書(補件)/94-07/94109739 1277691 路5 4的開口閉塞,並使引擎之起動及暖機運轉終了。 又,前述雖然已說明環境溫度及引擎溫度在低溫狀態時 自起動至暖機運轉終了之情形,但是馬達Μ因為藉因應於 溫度狀態之電氣信號而自ECU所輸入者,因此馬達Μ會因 應該電氣信號而動作,並可設定為因應於溫度狀態之最適 合的氣閥4之開度。 此處,根據本發明之怠速空氣控制裝置,在滑件3和圈 環2之間設有溝3 e和限制突部2 c,由於其可抑止滑件3 Φ 之迴轉,同時,可使滑件3在軸方向移動,因此,氣閥4 可使用和先前同樣構成之橫剖面圓形的氣閥4。 在使用先前的蠟元件之怠速空氣控制裝置則可將本發 明之怠速空氣控制裝置原狀地使用。 又,由於使圍繞在馬達Μ之外周的馬達箱1 a和對節流 體5 0的插入孔5 6之插入筒部1 b —體形成箱本體1,因此, 其可達成削減零件數量和小型化,特別是對如二輪機車收 容空間被限定者其可提高搭載性。The fixing member 6 which is inserted into the outer peripheral groove 1 f of the cylindrical portion 1 b inserted into the insertion hole 56 which is open at one end 50 0 a of the throttle body 50, and the case body 1 is fixed to the throttle body 50 . According to the above, the gas valve 4 is configured to be movable within the air wide guide hole 55, as shown in the figure. Next, the action of the idle air control device of the present invention will be described. The starting state of the engine or ambient temperature is indicated. When the engine is started, the synchronized ECU is output to the motor in response to the electrical signal in the low temperature state. The motor Μ is in a single direction according to the aforementioned signal. Range rotation. When the motor output shaft Ma is rotated in one direction, the slider 3 is greatly pulled up in the upward direction, and the gas valve 4 is also pulled up in the upward direction of the valve guide hole 55 in synchronization with the slider 3, so that The bypass air passage 54 is open. According to the above, a large amount of starting air can be supplied to the engine by the bypass air passage 504, and the engine can be started well in the low temperature state. Further, in the above, the motor output shaft Ma is rotated in one direction, and the slider 3 can be pulled up because the restriction of the ring 2 fixed to the Φ box body 1 is inserted into the groove 3e of the slider 3. The projection 2c can suppress the rotation of the slider 3, as a result. Next, when the start-up is completed, the engine temperature is gradually increased when the engine is warmed up, and the ECU outputs an electrical signal corresponding to the temperature rise to the motor 。. The motor output shaft Ma is rotated in the other direction opposite to the aforementioned one direction in accordance with the aforementioned electric signal, whereby the slider 3 is movable in the downward direction of the drawing, and at the same time, the gas valve 4 is also synchronized with the slider 3 The valve guide hole 5 5 moves inward in the downward direction, and as the temperature rises, the opening of the bypass passage 54 gradually decreases. Therefore, as the warm-up operation of the engine is synchronized, the amount of air supplied to the engine is gradually reduced, so that the engine does not have an unnecessary increase in the number of revolutions, and the engine can be warmed up. Further, when the warm-up operation of the engine is completely completed, the slider 3 is disposed at the lowest position of the ring 2, and the synchronized air valve 4 is also disposed at the most position of the valve guide hole 55. In the lower position, the opening of the bypass ventilator 15 312XP/invention manual (supplement)/94-07/94109739 1277691 is closed, and the start of the engine and the warm-up operation are finished. Further, although the above description has been made of the case where the ambient temperature and the engine temperature are at the low temperature state from the start to the end of the warm-up operation, the motor Μ is input from the ECU because of the electrical signal due to the temperature state, so the motor Μ will respond accordingly. It is operated by an electrical signal and can be set to the optimum degree of opening of the gas valve 4 in response to the temperature state. Here, according to the idle air control device of the present invention, the groove 3 e and the restricting projection 2 c are provided between the slider 3 and the ring 2, since it can suppress the rotation of the slider 3 Φ, and at the same time, can be slipped The member 3 is moved in the axial direction, and therefore, the gas valve 4 can use the gas valve 4 having a circular cross section which is formed in the same manner as before. The idle air control device of the present invention can be used as it is in the idle air control device using the previous wax member. Further, since the casing 1b is formed by inserting the cylindrical portion 1b of the motor casing 1a surrounding the outer circumference of the motor casing and the insertion hole 56 of the counterfluid fluid 50, it is possible to achieve a reduction in the number of parts and miniaturization. In particular, it is possible to improve the mountability in a space where the storage space of the two-wheeled vehicle is limited.
又,藉使形成在滑件3之外周部3 f和氣閥4之内周部 4 a之間的間隙S 1及形成於氣闊4之外周部4 b和圈環2之 内周部2 b之間的間隙S 2構成比馬達輸出軸M a之長度方向 軸心X-X和氣閥導引孔55之長度方向軸心Y_Y的偏心量Z 更大,怠速空氣控制裝置要組裝在節流體5 0時,可將氣閥 4確實地同心配置在氣閥導引孔5 5内而維持氣閥4之良好 的動作特性。 又,在氣閥導引孔55内可同心配置氣閥4是因為對前 16 312ΧΡ/發明說明補件)/94-07/94109739 1277691 述偏心量Z具有間隙S1、S 2,及,氣閥4對滑件3不是以 機械固定,因此而容許藉氣閥彈簧5被彈性押壓並在直徑 方向移動所致者。 又,滑件3之引入側(圖中向上方向的移動)的移動, 為藉設在内螺紋孔3 b的底部之引入側停止部3 c抵接至馬 達輸出軸M a之下端M b而被固定者。此一狀態在圖1的中 心線如右側部份所示。 另一方面,滑件3之延伸側(圖中向下方向的移動)的 Φ 移動,為藉設在滑件3的上方之繫止鍔部3d的下面抵接設 在圈環2之内方底部的延伸側停止部2 d而被固定。此一狀 態在圖1的中心線如左側部份所示。 根據上述,初始化自任何的固定位置均可。Further, the gap S 1 formed between the outer peripheral portion 3 f of the slider 3 and the inner peripheral portion 4 a of the gas valve 4 and the outer peripheral portion 4 b formed on the outer periphery of the air gap 4 and the inner peripheral portion 2 b of the ring 2 The gap S 2 is formed to be larger than the eccentric amount Z of the longitudinal direction axis XX of the motor output shaft Ma and the longitudinal direction axis Y_Y of the valve guide hole 55, and the idle air control device is to be assembled at the throttle body 50 The gas valve 4 can be surely arranged concentrically in the valve guide hole 55 to maintain good operating characteristics of the valve 4. Further, the gas valve 4 can be concentrically arranged in the gas valve guide hole 55 because the eccentric amount Z has a gap S1, S 2 and a gas valve for the first 16 312 ΧΡ / invention description) /94-07/94109739 1277691 The pair of sliders 3 are not mechanically fixed, and thus the valve spring 5 is allowed to be elastically pressed and moved in the radial direction. Further, the movement of the introduction side of the slider 3 (movement in the upward direction in the drawing) is such that the introduction side stop portion 3c of the bottom of the internal thread hole 3b abuts against the lower end Mb of the motor output shaft Ma. Being fixed. This state is shown in the center line of Fig. 1 as shown in the right part. On the other hand, the Φ movement of the extension side (movement in the downward direction in the drawing) of the slider 3 is abutted in the ring 2 by the lower surface of the stopper portion 3d which is provided above the slider 3. The extension side stop portion 2d of the bottom portion is fixed. This state is shown in the center line of Fig. 1 as shown on the left side. According to the above, it can be initialized from any fixed position.
又,在馬達輸出軸Ma之上方部外周,藉滑接配置密封 墊R的唇狀部Ra時,自旁通氣路54進入圈環2的内方之 碳等則不會從馬達輸出軸Ma的外周進入馬達Μ内,馬達Μ 則可長期間安定使用。 又,藉馬達箱la圍繞馬達Μ的周圍也可和上述一起賦 予其安定性。 又,由於前述密封墊R為藉馬達箱1 a内之段部和圈環2 之上端2 a而被挾持,因此,其不必準備為了固定密封墊R 之特別的構件。 【圖式簡單說明】 圖1表示本發明之燃料喷射裝置之怠速空氣控制裝置之 一實施例的縱剖面圖。 17 312XP/發明說明書(補件)/94-07/94109739 1277691 圖2為圖1之滑件、氣閥部的重要部份擴大半縱剖面圖。 圖3為圖1之A - A線的重要部份擴大半縱剖面圖。 圖4為先前的燃料喷射裝置之怠速空氣控制裝置之縱剖 面圖。Further, when the lip portion Ra of the gasket R is placed on the outer circumference of the upper portion of the motor output shaft Ma by sliding, the carbon or the like entering the inside of the ring ring 2 from the bypass air passage 54 does not output the shaft Ma from the motor. The outer circumference enters the motor cymbal, and the motor Μ can be used for a long period of time. Further, the circumference of the motor casing around the motor casing can be given stability together with the above. Further, since the gasket R is held by the segment in the motor casing 1a and the upper end 2a of the ring 2, it is not necessary to prepare a special member for fixing the gasket R.
