Patent number: 9068543Abstract: The invention relates to a fuel injection system of an internal combustion engine, comprising a high-pressure pump. A high-pressure outlet (4) of the high-pressure pump is connected to a high-pressure accumulator (23) that has at least one accumulator outlet (13a, 13b) for connecting to a fuel injector. According to the invention, a fuel injection system which is compact and operates in a highly reliable manner is provided. This is achieved in that the high-pressure accumulator (23) is directly adapted to the high-pressure pump and in that the accumulator outlet (13a, 13b) is aligned in a precisely defined position with respect to the high-pressure pump.Type: GrantFiled: December 29, 2010Date of Patent: June 30, 2015Assignee: Robert Bosch GmbHInventors: Sylvain Besancon, Friedrich Boecking, Sakae Sato

Patent number: 7661413Abstract: Disclosed is a fuel supply pump including a tappet structure body having a roller that contacts a cam and a tappet body disposed with a roller housing portion in which the roller is housed, with a pressure adjusting member for dispersing load force being interposed between the tappet body and a plunger. The pressure adjusting member includes a concave portion in a center portion of a surface that faces the tappet body and contacts the tappet body at the peripheral portion of the concave portion.Type: GrantFiled: September 15, 2005Date of Patent: February 16, 2010Assignee: Bosch CorporationInventors: Sakae Sato, Nobuo Aoki, Misao Tanabe, Tsutomu Miyazaki

Patent number: 7592134Abstract: The present invention relates to a plasma product or a serum product with an extremely low risk of viral contamination and a method for producing the same. Before treating plasma or serum to be used as a raw material for producing a plasma product or a serum product using a virus removal membrane, leucocytes contaminating the blood are removed. Thus, a plasma product or a serum product with an extremely low risk of viral contamination can be efficiently produced while preventing clogging. Since clogging scarcely arises, it is possible to carry out efficient filtration without applying an elevated pressure as the filtration proceeds.Type: GrantFiled: October 16, 2003Date of Patent: September 22, 2009Assignee: Asahi Kasei Medical Co., Ltd.Inventors: Sakae Sato, Tetsuo Sato, Thierry Burnouf, Miryana Radosevich, Hadi Alphonse Goubran

Publication number: 20090185923Abstract: The invention provides fuel supply pump that can improve the durability of a fuel inlet valve and stably pressure-feed high pressure fuel of a large flow rate. In the fuel inlet valve according to the invention, a valve piston includes, in its outer surface in the vicinity of an end portion on an opposite side of a collar portion, a groove portion to which a fastener for fixing the valve piston and a spring seat locks. The spring seat includes an open portion into which the valve piston is inserted and includes, along an edge of the open portion, a step portion to which the fastener locks. The valve piston is inserted into the open portion of the spring seat, and the fastener is thereafter caused to lock to the groove portion of the valve piston. The spring seat is energized by a spring to cause the fastener to lock to the step portion, whereby the spring seat is fixed to the valve piston.Type: ApplicationFiled: April 23, 2007Publication date: July 23, 2009Inventors: Sakae Sato, Masatsugu Hayashida, Koji Hatanaka

Patent number: 7537252Abstract: Bumper beam of a closed sectional shape includes: a vehicle-body-side inner wall portion to be mounted on a vehicle body; upper and lower outwardly-extending wall portions that extend from the upper and lower ends of the inner wall portion toward the outside of the vehicle body; an outer wall portion connecting the outwardly-extending wall portions; and at least one horizontal inner rib connecting the outer wall portion and the inner wall portion, the outer wall portion having a vertical wall portion extending vertically downward from the outer end of the upper outwardly-extending wall portion and a slanted wall portion slanted from the lower end of the vertical wall portion toward the vehicle body. Gusset of a closed sectional shape includes a horizontal rib for dispersing an impact force at least to the slanted wall portion.Type: GrantFiled: April 23, 2007Date of Patent: May 26, 2009Assignees: Honda Motor Co., Ltd., YKK AP Inc., YKK CorporationInventors: Shigeyuki Nagai, Shigekazu Koga, Keiichi Honda, Kazuyuki Fukagawa, Daisaku Nakazato, Sakae Sato

Publication number: 20050001071Abstract: An object of the present invention is to provide a fuel path sealing structure for a fuel injection valve that is capable of preventing a high pressure fuel leak by increasing the seal surface pressure between a first body such as an injector housing, and a second body such as a nozzle body to thus permit an increase in the seal surface pressure without a change to the size of the nozzle nut or the corresponding tightening force. The present invention is directed toward the formation, over a predetermined surface area, of slightly shallow micro-recesses, in regions other than the high pressure fuel paths and the periphery of the seal surfaces, that is, at the center of the seal surface.Type: ApplicationFiled: October 31, 2002Publication date: January 6, 2005Inventors: Kunihiko Hashimoto, Kazutaka Iioka, Toshiki Sawaki, Sakae Sato
