摘要： PROBLEM TO BE SOLVED: To provide a high pressure pump which prevents a plunger from falling through a cylinder hole, or the like in a state that a sliding surface of the plunger is protected so as not to cause a dent, foreign matter sticking or the like thereon during assembly of the high pressure pump, or the like.SOLUTION: A plunger stopper 34 has a stopper part (368) to which a stepped part 214 of a plunger 21 comes into contact during movement in a cylinder hole 12 of the plunger 21. The plunger stopper 34 regulates the movement of the plunger 21 while causes a sliding surface of the plunger 21 to contact to an inner wall surface of a cylinder hole 11 and, thereby, a state in which the sliding surface of the plunger 21 is protected so as not to cause dent, foreign matter sticking or the like is retained when performing a reciprocating movement in the cylinder hole 11 of the plunger 21 during actuation after assembly of a high pressure pump 3 or when preventing the plunger 21 from falling through the cylinder hole 11 during an assembling process of the high pressure pump 3 and an engine mounting process.

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 provide a high pressure pump for preventing the leakage of high pressure fuel, while allowing easy and accurate assembly of a discharge valve device into a discharge passage of a discharge-passage integrated pump-body.SOLUTION: In a discharge valve part 70 of the high pressure pump 1, an end face 811 of a seat part 81 previously pressed into a medium-inner-diameter passage 712 is encircled by a sloping part 73 located in a boundary area between the medium-inner-diameter passage 712 and a large-inner-diameter passage 713. The sloping part 73 is linear-taper shaped to be smaller from the side of a fuel outlet 72 toward the side of a compression chamber 12. Thus, a discharge valve member 82 to be inserted through from the side of the fuel outlet 72 toward the medium-inner-diameter passage 712 is direction-adjusted by the sloping part 73, when inserted, and so a first end face 821 of the discharge valve member 82 easily and accurately abuts to an end face 811 of the seat part 81. The discharge valve member 82 subjected to aligning action by the sloping part 73, when being inserted, is easily and accurately positioned relative to the seat part 81.

摘要： PROBLEM TO BE SOLVED: To restrain a bellows from acting acts as a resistance with respect to the elongation of a laminated body 2 in a piezo injector even when elongating a laminated body 2 of a piezoelectric element. SOLUTION: When a laminated body 2 is elongated, a large diameter bellows 26 is shortened while a small diameter bellows 27 is elongated in a bellows assembly 24. As a result, a resistance against the elongation of the laminated body 2 is reduced by axially shortening of the large diameter bellows 26 even when the resistance against the laminated body 2 is increased through the elongation of the small diameter bellows 27. Therefore, the bellows assembly 24 can restrain the action as a resistance against the elongation of the laminated body 2 as compared with a single bellows. By adopting the bellows assembly 24 in the piezo injector, the resistance against the elongation of the laminated body 2 can be suppressed in comparison with the case of employing the single bellows.
