A common rail has a main pipe rail with a peripheral wall. A boss is provided on the peripheral wall, and a branch hole extends through the boss and into the main pipe rail. The branch hole has a pressure receiving seat face. A branch pipe has a pressing seat face that is urged into the pressure receiving seat face by a fastening nut. An orifice pipe is mounted in the branch hole and abuts against an end of the branch pipe without effecting sealing performance between the pressing seat face and ...

A common rail is provided in the pipe joint of the branch connector to improve the strength and resistance against the internal pressure fatigue; said common rail having a longitudinal conduit of a substantially circular section therein and a plurality of branch holes formed in its circumferential wall at an axial spacing, each of the branch holes having a pressure receiving seat formed on the circumferential face thereof and opened to the outside, wherein connected by means of branch connector ...

There is provided a common rail which can reduce a maximum stress value generated in an inner peripheral edge portion of a lower end of a branch hole and can further improve an internal pressure fatigue strength. In the common rail comprising at least one branch hole provided on a peripheral wall portion of a main pipe rail having a communication passage inside an axial core, a pressure receiving seat surface communicating with a branch pipe having a communication passage communicating with the ...

The invention relates to a common rail for a common rail fuel injection system of an internal combustion engine, having a tubular base body which is equipped with a plurality of connection openings. To enable the common rail to withstand higher pressures than conventional common rails, according to our embodiment at least two connection openings are disposed diametrically opposite one another in the tubular base body. In a further version of the invention, diametrically opposite at least one of ...

The invention relates to a common rail for a common rail fuel injection system of an internal combustion engine, having a tubular base body whose interior communicates with a plurality of connections. To increase the high-pressure strength, the interior is formed by at least two substantially circular-cylindrical recesses or bores which communicate with one another and whose longitudinal axes are parallel to one another. The connections originate only at the jacket face of one of the substantial...

A common package serves as, for example, a common network interface package for a switching system. Since the common package is usable for various purposes, its cost is reduced and the cost of maintenance and management of the switching system is reduced. The common package is a printed board package (35) installed in an apparatus and used for a variety of purposes. The common package includes a programmable device (36), memories (45 to 48) for storing programs to configure the programmable devi...

A ring-shaped connecting portion is formed on a seat surface side of a pipe connector. The connecting portion is tapered so that thickness thereof gradually reduces toward a tip end thereof. A protrusion is formed on the tip end of the connecting portion. A ring-shaped groove is formed on a flat outer peripheral surface of a common rail. By fitting the protrusion into the groove, the connector can be positioned to a predetermined position of the common rail. In this structure, current can be con...

A method for mounting a film, used to fabricate a mask for use in screening an electronic device, to a common carrier frame. The common carrier frame has an outer edge along an outer periphery and an opening in a central portion of the frame. The method includes applying external pressure to the frame outer edge to compress the frame inward and reduce the opening, securing a film to the frame, the film covering the frame opening, and releasing the pressure on the frame to expand the opening and ...

A small-diameter circular column portion having a diameter slightly smaller than that of a small-diameter hole (press-fitting hole) of an inside-outside communication hole is formed at a press-fitting end portion of a bush. A narrow annular clearance is formed between the small-diameter circular column portion and the small-diameter hole when the bush is press-fitted. Even if a press-fitting burr is produced at the press-fitting end portion during manufacturing of a common rail, the press-fittin...

The invention relates to a common rail for a common rail fuel injection system of an internal combustion engine, having a base body whose interior communicates with a plurality of connections. To increase the high-pressure strength, the interior is formed by at least two substantially circular-cylindrical recesses whose longitudinal axes are disposed parallel to one another and which communicate with one another, and the connections discharge into the interior of the base body, in the communicat...
