摘要： PROBLEM TO BE SOLVED: To provide a high pressure pump capable of suppressing vibration of a housing.SOLUTION: In a high pressure pump 10, a cylindrical portion 41 of a housing 40 has a reinforcement portion 54 on its outer wall. The reinforcement portion 54 is disposed on the center of a flat plate portion formed by a polygonal portion 52 of the cylindrical portion 41 of the housing 40, and has a plurality of dimples 55. Rigidity of the cylindrical portion 41 is improved by the reinforcement portion 54, so that the cylindrical portion is hardly vibrated. That is, the reinforcement portion 54 can lower a vibration level of the cylindrical portion 41 of the housing 40 caused by vibration of the housing 40 due to vibration of an engine, when the high pressure pump 10 is mounted on the engine. Thus generation of noise caused by the vibration of the cylindrical portion 41 of the housing 40 can be suppressed.

摘要： PROBLEM TO BE SOLVED: To improve valve closing responsiveness in current-carrying OFF time to a coil, in a normally closed solenoid valve.SOLUTION: This solenoid valve applied as a suction valve part 30A of a high-pressure pump, generates electromagnetic attraction force between a flange 55A and a movable core 53 when carrying an electric current to the coil 51, and the movable core 53 moves in the attraction direction (the left direction of a drawing). When current-carrying to the coil 51 is turned off, the electromagnetic attraction force disappears, and the movable core 53 and a stem 41 integrally move in the anti-attraction direction (the right direction of the drawing) by energizing force of a second spring 43A. A valve element 32 also moves in the valve closing direction for seating on a seat part 316 of a seat member 31 by energizing force of a first spring 33. Since the energizing direction of the first spring 33 and the second spring 43A is the same, weight of the movable core 53 and the stem 41 does not become a load to valve closing operation of the valve element 32. The lightweight valve element 32 can move independently.

摘要： PROBLEM TO BE SOLVED: To prevent biting-in of foreign matter in fluid to a clearance between a guide hole of a seat and a shaft part.SOLUTION: A shaft part release part 334 for communicating between a low pressure passage 311 and an armature chamber 37, is arranged on the outer peripheral surface of a shaft part 332 in a movable member 33. Thereby, when the fluid enters in and out between the armature chamber 37 and the low pressure passage 311, its fluid mainly passes through the shaft part release part 334, and is hard to infiltrates into a sliding part of the guide hole 313 and the shaft part 332, so that the biting-in of the foreign matter in the fluid to its sliding part, can be prevented.

摘要： PROBLEM TO BE SOLVED: To secure both oil-tightness and slidability, in a boosting mechanism 4 of an injector 1. SOLUTION: The boosting mechanism 4 has a cylindrical piston 23 penetrating in the axial direction, and a bar-shaped piston 25 loosely inserted into the cylindrical piston 23 and having a tip part 24 projecting to the tip side from the cylindrical piston 23 and engaging with the cylindrical piston 23. Thus, since the cylindrical piston 23 and the bar-shaped piston 25 move by mutually engaging, even if large diameter side and small diameter side sliding clearances are set small for securing the oil-tightness, restriction received to one from the other is weak when the cylindrical piston 23 and the bar-shaped piston 25 move. Thus, independency becomes high in the moving direction of the cylindrical piston 23 and the moving direction of the bar-shaped piston 25, and risk of causing sliding failure is reduced in the tip part 24 of the cylindrical piston 23 and the bar-shaped piston 25. Thus, both the oil-tightness and slidability can be secured in the boosting mechanism 4 of the injector 1. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：解决方案：在喷射器1的升压机构4中确保油密性和滑动性。解决方案：升压机构4具有沿轴向穿透的圆柱形活塞23和杆形状的活塞25松动地插入到圆柱形活塞23中，并且具有从圆柱形活塞23突出到尖端侧并与圆柱形活塞23接合的尖端部分24.因此，由于圆柱形活塞23和条形活塞25移动通过相互接合，即使大直径侧面和小直径侧滑动间隙被设定得小以确保油密性，当圆柱形活塞23和条形活塞25移动时，彼此接收的限制也是较弱的。因此，圆柱形活塞23的移动方向和条形活塞25的移动方向的独立性变高，并且在圆柱形活塞23的顶端部分24和杆形活塞中减小了引起滑动故障的风险因此，可以在喷射器1的增压机构4中确保油密性和滑动性。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To achieve dry coil of a solenoid assembly 8 of a solenoid valve 2 for an injector performing fuel injection to a diesel engine. SOLUTION: The solenoid assembly 8 of the solenoid valve 2 is welded and fixed to an injector body 9 by all-round laser welding. Due to this, a fixing method of the solenoid assembly 8 with respect to the injector body 9 is simplified, and moreover, a space between an outer peripheral part of the solenoid assembly 8 and an inner peripheral part of the injector body 9 is hermetically sealed. This makes it possible to securely seal a space between a communication chamber into which leak fuel is flowed and a coil storing part 49 for storing a solenoid coil 4. Therefore, since dry coil of the solenoid assembly 8 can be achieved, reliability of the solenoid coil 4 can be improved, compared to conventional wet coil, and in addition, a seal structure of fuel can be simplified.
