摘要： PROBLEM TO BE SOLVED: To prevent air from accumulating in a cooling water passage of an EGR valve by connecting the cooling water passage of the EGR valve to a passage for an air escape pipe in an engine cooling water circuit. SOLUTION: A water-cooled EGR valve 9 in an exhaust recirculating device is provided with an exhaust gas inlet 9a and an exhaust gas outlet 9b, and a valve stem 9f is arranged in an exhaust gas passage for connecting them to each other. A cooling water inlet 9c and a cooling water outlet 9d are arranged as a water cooling structure, and a cooling water passage 9e is arranged between the cooling water inlet 9c and the cooling water outlet 9d. In this case, the cooling water inlet 9c and the cooling water outlet 9d are connected to a passage of an air escape pipe in an engine cooling water circuit. Cooling water which flows to a head tank passing the air escape pipe is led from the cooling water inlet 9c into a cooling water passage 9e, and it passes the circumference of the valve stem 9f for cooling the EGR valve 9, and then it is delivered from the cooling water outlet 9d to the air escape pipe.

摘要： PROBLEM TO BE SOLVED: To enhance reliability by reducing the wear of locking pins exerted with the torque of a torsion ring and that of the torsion ring. SOLUTION: This scissors gear has a main gear 11 with a first locking pin 11d with which one end of a torsion ring 13 is locked, and has a subsidiary gear 12 with a second locking pin 12b locked with the outer end of the torsion ring. The subsidiary gear 12 is provided on the same axis as the rotation axis of the main gear 11 and on one side of the main gear 11 via the torsion ring 13 in such a way to be rotatable relative to the main gear 11. The torsion ring 13 is designed to produce torque with which the subsidiary gear 12 is circumferentially twisted with respect to the main gear 11 by the first and second locking pins 11d, 12b. Tubular carburized bushes 14, 14 are fitted around the first and second locking pins 11d, 12b, and the ends of the torsion ring are locked to the first and second lock pins 11d, 12b via the bushes.

摘要： PURPOSE: To control the maximum rotational frequency of an engine just like in the case of a limit speed governer even in the case where an all-speed governer is used. CONSTITUTION: A first cable 12 in linkage with an accelerator pedal is connected to one end of a main link 13. In addition, a speed lever is connected to the other end of this main link via a second cable 14. A base 18 is provided with both first and second stoppers 24 and 26. A support link 19 is pivotally attached to a main shaft 18a installed in this base, and further this support link is provided with a tongue piece 19a at the one end and the main link is pivotally attached to the other end. Likewise an auxiliary link 22 is pivoted to the main shaft, and an actuator 23 is pivoted to one end of this auxilairy link. This actuator, in its operation, is made to contact with the first stopper via the tongue piece, securing the support link, and in the inoperativeness, it releases the support link. At this release, one end of the support link comes into contact with the second stopper at a time when an operating value of the accelerator pedal becomes as much as the specified one.

摘要： PURPOSE:To obtain large braking force by driving an exhaust valve by means of a brake operating cam through a fluid tappet and opening the exhaust valve in correct timing at the end of compression stroke to operate an engine as a compressor. CONSTITUTION:A cylinder guide 21 and a cylinder 22 are disposed in a cylinder housing 11 fixed to an engine, and a tappet piston 23 is slidably inserted in the cylinder 22. The cylinder 22 is connected to a brake set valve 13 through a supply path 35 and a return path 36, and connected to a pressurized fluid source at the time of braking. Accordingly, at the time of braking, the lift of a brake operating cam 15 is transmitted to the cylinder 22 to open and close an exhaust valve 43. Thus, the timing of the exhaust valve 43 is correctly controlled by the brake operating cam 15, so that the exhaust valve is set at expansion stroke from the end of compression stroke, and an engine is used as a compressor to obtain large braking force.

摘要： PURPOSE:To prevent deterioration of combustion efficiency due to insufficient air, by controlling a bypass valve through boosting pressure thereby shifting the tuning point of inertia supercharge and improving the supercharge efficiency upon abrupt increase of engine rotation. CONSTITUTION:In the low engine rotation area, the boosting pressure PB is higher than the spring 8 and the atmospheric pressure PA to perform inertia supercharging. Here the tuning point of inertia supercharge is set in the low rotation area. In the high engine rotation area, it is supercharged mainly by a turbo-charger to bring the tuning point into the high rotation area. Since the boosting pressure PB is high at this time, the bypass valves 7 and 6 are closed. Upon abrupt increase of engine rotation from low to high rotation area, the turbo-charger can not follow quickly to cause lack of air. Consequently the boosting pressure will drop to open the bypath through the bypass valve 7.
摘要翻译：目的：为了防止由于空气不足引起的燃烧效率的劣化，通过增压压力控制旁通阀，从而使调谐点惯性增压转移，并且在发动机转速突然增加时提高增压效率。构成：在低发动机转速区域，增压压力PB高于弹簧8和大气压力PA进行惯性增压。这里，调谐点惯性增压设定在低旋转区域。在高发动机旋转区域中，主要由涡轮增压器增压，使调谐点进入高旋转区域。此时由于增压压力PB高，旁通阀7,6关闭。发动机从低转速到高转速区域的转速突然增加时，涡轮增压器不能快速跟随导致空气不足。因此，升压压力将下降以通过旁路阀7打开。

摘要： PURPOSE:To check an oil level smoothly without contaminating the hands with oil by providing a movable grip on the oil-level gage of an engine. CONSTITUTION:When an oil level is checked, a handle 3 is held with one hand, and a movable grip 9 is grasped with the other hand. A sealing plug part 7b is pulled out of the base end part of the movable grip 9. A sealing-plug part is pulled out of the opening end of a guide pipe. A flexible member is completely pulled out of the guide pipe so that the movable grip is relatively moved to the tip side of the flexible member 5. Then, both the movable grip and the handle are held with one hand. A level stick is wiped out with cloth and the like using one hand, and the attached oil is removed. Thereafter, the flexible member is completely inserted into the guide pipe and returned to the original state once. Then, the flexible member is completely removed from the guide pipe again together with the movable grip. The oil attached to the level stick is observed, and the oil level in the oil pan is detected.

摘要： PURPOSE:To simplify the structure and the assembling work and to obtain a sure sealing effect by mounting a plurality of annular flat plate seal rings made of metal in a clearance between connecting parts in the inclined condition. CONSTITUTION:At connecting parts of tubes, a tube end 11 having a smaller diameter is fitted in a larger diameter part 13 formed at the other tube end 12. Metal seal rings 14 are mounted in a clearance H formed between an outer peripheral surface of the tube end 11 and an inner peripheral surface of the larger diameter part 13. In this case, an outer diameter of the seal ring 14 prior to fitting is larger than an inner diameter of the larger diameter part 13, and an inner diameter of the seal ring 14 is nearly equal to an outer diameter of the tube end 11. On the occasion of assembling, the seal rings 14 is first brought into contact with the tube end 11 and a tapered part 17 of the larger diameter part 13, and is thereafter pressed into an inner peripheral surface 16 of the larger diameter part 13 along the tapered part 17. At this time, the seal ring 14 is mounted in the inclined condition because the clearance H is narrower than a width of the seal ring 14 in its radial direction.

摘要： PURPOSE: To improve the assembly performance and reliability by reducing each abrasion of a torsion ring an d an engagement pin. CONSTITUTION: A scissors gear 10 is equipped with a torsion ring 13, main gear 11 having an engagement pin 11d, and a subgear 12 having an engagement pin 12b. The subgear 12 is installed in a rotatable manner through a torsion ring 13 on the same axis line to the revolution axis of the main gear 11. The torsion ring 13 generates a torsional force for twisting the subgear 12 in the circumferential direction. The recessed parts 11e and 12e into which the head parts of an engagement pin 12b can be intruded are formed on the main gear 11 and the subgear 12. The subgear 12 has a stopper pin 16 in the vicinity of the engagement pin 12b in the installed state on one side surface of the main gear 11. The stopper pin 16 makes contact with the engagement pin 12b before the state where the main gear 12 and the subgear 12 are meshed with the opponent gear, and separates from the engagement pin 12b in the state after the main gear 11 and the subgear 12 are meshed with the opponent gear.
