摘要： Metal discs, preferably circular, are cut to a precise diameter and drawn to a preform with a channel and skirt for an aerosol valve mounting cup. The preform then undergoes further forming operations at the stations in a press system. 'Bumping' is carried out on the skirt edge at a station, to eliminate non- burr trimming of the cup edge, save material and obtain a carefully controlled skirt height and a substantially even skirt edge with minimized earring. The resultant cup terminating skirt edge is characterized by reformed metal. A further coaxing or pinch-cut operation may be performed on the cup skirt.

摘要： A fluid selection valve unit is provided which is applicable to an exhaust gas control valve, a waste gate valve, or the like provided between a high-pressure-stage supercharger and a low-pressure-stage supercharger of a two-stage supercharging exhaust turbocharger so as to control an amount of exhaust gas supplied to the high-pressure-stage supercharger and the low-pressure-stage supercharger, and which is capable of improving control performance of a valve in such a manner that a passage area gently varies with respect to an opening degree of a valve member so as to minutely control an exhaust gas amount by using the opening degree of the valve. In a fluid selection valve unit including: a valve seat provided in a fluid passage; and a valve member of which one end is supported to a rotary shaft so as to be rotatable about a shaft center of the rotary shaft in a direction moving away from the valve seat, the valve seat includes a side surface having a predetermined depth and a bottom surface continuous to the side surface, the valve member includes a bottom portion and a side end surface formed above the bottom portion, and the valve member is configured so that a passage area of a gap formed between the side end surface of the valve member and the side surface of the valve seat is smaller than a contact passage area formed between the bottom portion of the valve member and the bottom surface of the valve seat during a time when the bottom portion of the valve member comes into contact with the bottom surface of the valve seat by the rotation of the rotary shaft, and the rotary angle increases up to a predetermined value of the rotary angle.

摘要： Micro check valves having a free-floating member for controlling flow of fluid in microfluidic and biomedical applications and methods of fabrication. A micro check valve includes a valve seat, a valve cap that contacts the valve seat and an untethered floating member that can move between the valve seat and the valve cap. Certain micro check valves have zero cracking pressure and no reverse leakage. Certain other valves may be configured to permit flow of fluid within a pressure range. The floating member can be solid or define an orifice, and the valve seat can have one or two levels. Valves can be configured to allow fluid to flow when the floating member is pushed by fluid against the valve cap or against the valve seat. The valve seat may be silicon or another material that is compatible with micromachining processes, and the valve cap and the floating member may be a polymer such as Parylene.

摘要： The invention relates to a method for working the edge of a high pressure-resistant part, according to which the edge is hydro-erosively rounded off in a working step. The invention also relates to a method and a device for the hydro-erosive rounding of the edge of a high pressure-resistant part, especially the edge of a bore intersection of a high pressure-resistant part of a fuel injection system. According to said method, a liquid to which abrasives are added is directed across the edge that is to be rounded in the area of a first continued bore to a branching second bore. In order to optimize the result of the rounding process and thus in order to optimize the high pressure-resistance of the part, the edge (5) and the surfaces (4, 6) of the high pressure-resistant part (1) adjacent to the edge (5), before the step of hydro-erosive rounding, are subjected to compressive strains in the area of their surfaces by means of a grinding and/or honing method. The method and the device for the hydro-erosive rounding are improved by inserting an obturating element (9) in the continued first bore (2) behind the branching second bore (3), when seen from the main direction of flow (S) of the liquid (8) to which abrasives (7) are added, to deflect the liquid (8) to which abrasives (7) are added from the first bore (2) to the second bore (3).

摘要： A fuel injector seat for a fuel injector assembly, and more particularly for a high-pressure fuel injector assembly, having a number of features for minimizing the formation of combustion chamber deposits on the seat, providing a selected finish on a needle-sealing portion, and reducing sac volume. These features include positioning a transition portion between the needle-sealing portion and an orifice portion, positioning a sharp edge at the outlet of the orifice portion, and applying a surface energy coating to certain surfaces of the seat. This invention also relates to a fuel injector seat and method of manufacturing the fuel injector seat, and a method of evaluating when the transition portion is required between the orifice and needle-sealing portions for a particular seat arrangement.

摘要： The invention relates to a method for producing a valve seat body (5) of a fuel injection valve (1) comprising swirl channels (36) that are provided inside a recess (35) for generating swirl. To this end, a valve seating (6) of the valve seat body (5) interacts with a valve closing body (4) of the fuel injection valve (1) in order to form a tight seat, and the recess (35) serves as a guide of the valve closing body (4). The inventive method comprises the following steps: manufacturing a blank of the valve seat body (5); providing the recess (35), the valve seating (6) and at least one spray opening (7) inside the blank of the valve seat body (5) and providing the swirl channels (36) inside the recess (35). A non-cutting processing step is used to provide the swirl channels (36) inside the recess (35).
