摘要： PROBLEM TO BE SOLVED: To provide a high-pressure pump efficiently sucking fuel when the fuel is sucked by a plunger.
SOLUTION: In comparison with fuel supplied from an inlet opening 133 through a supply passage 18, fuel is forcibly supplied from the opening of a volumetric chamber. Thereby, fuel colliding with a pulsation damper easily forms a crosswise flow in a fuel gallery 13, and inflow of supply fuel from an inlet is easily blocked. For these reasons, an opening edge wall 135 protrudes from the opening edge of the inlet opening 133. The opening edge wall 135 is a cylindrical wall surrounding the inlet opening 133.

摘要翻译：要解决的问题：提供当通过柱塞吸入燃料时有效地吸入燃料的高压泵。解决方案：与从入口开口133通过供应通道18供应的燃料相比，从容积室的开口强制供给燃料。因此，与脉动阻尼器碰撞的燃料容易在燃料管道13中形成横向流动，并且容易地阻塞来自入口的供给燃料的流入。由于这些原因，开口边缘壁135从入口开口133的开口边缘突出。开口边缘壁135是围绕入口开口133的圆柱形壁。（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply apparatus capable of suppressing an operating sound made when moving a movable part into a closing side position. SOLUTION: A driving voltage is built up at time T1, but the driving voltage is controlled so that the driving voltage before closing immediately before a needle 64 moves into the closing side position is a set value. For example, the driving voltage is controlled so that the driving voltage at time T2 is Vp1. If the driving voltage Vp1 before closing is appropriate, the moving speed (an inclination indicated by a symbol K) of the needle 64 can be suppressed, that is, "soft landing" of the needle 64 can be achieved. The driving voltage Vp before closing is set by learning control, that is, the driving voltage before closing is gradually lowered, and whether fuel pressure is lowered is determined to carry out learning.

摘要翻译：解决的问题：提供一种能够抑制将可动部件移动到关闭侧位置时产生的操作声音的燃料供给装置。解决方案：在时间T1建立驱动电压，但是控制驱动电压使得在针64移动到关闭侧位置之前关闭之前的驱动电压是设定值。例如，控制驱动电压，使得时刻T2的驱动电压为Vp1。如果关闭前的驱动电压Vp1适当，则可以抑制针64的移动速度（由符号K表示的倾斜度），即可以实现针64的“软着陆”。关闭前的驱动电压Vp是通过学习控制来设定的，即，关闭前的驱动电压逐渐降低，并且确定燃料压力是否降低，以进行学习。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high pressure fuel pump increasing delivery efficiency. SOLUTION: A stopper 42 includes a projection part 421 projecting inward of a valve member 41. The projection member 421 fills a space formed at an inside of the cylindrical valve member 41. Consequently, volume of the inside of the valve member 41 is reduced by the projection part 421. As a result, volume of the inside of the valve member 41 communicating to a pressurizing chamber 113 via a suction passage 112 is reduced. Fuel pressurized at the inside of the valve member 41, thereby, is reduced and total quantity of pressurized fuel is reduced when fuel in the pressurizing chamber 113 is pressurized with a rise of a plunger 13. Consequently, pressurizing efficiency and delivery efficiency of fuel can be increased. COPYRIGHT: (C)2009,JPO&INPIT

摘要：【課題】直噴型燃料噴射ポンプの騒音を抑制する。【解決手段】プランジャ74が上死点に向けて移動する間、吸入弁(第2の弁部材)64は、弁座66に着座している。ソレノイドコイル56は加圧行程から継続して励磁状態にあり、ニードル(第1の弁部材)58は吸引されている。プランジャ74が上死点から下方向へ移動を開始すると、第3の容積室72が減圧される。減圧によって吸入弁64はストッパ突起104へ向けて移動し、浮動状態になる。吸入弁64がストッパ突起104に向けて移動する間に、ソレノイドコイル56への通電が遮断され、非励磁となる。この結果、ニードル58が移動し、吸入弁64が最高の速度で移動しているときに、ニードル58が吸入弁64に衝突する。その後、それらはストッパ突起104に衝突する。このような二段階の衝突が騒音を抑制する。【選択図】図4
