    摘要： A gas-blast switch possessing a fixed contact and a movable contact and a blast or discharge nozzle surrounding one of the contacts, the blast nozzle having its inlet connected with the outlet of a pump compartment for an extinguishing gas, this pump compartment can be pressurized by the switch cut-off or switching-off movement, and wherein the narrowest location or throat of the blast nozzle is arranged in the direction of blowing downstream with respect to the aforementioned one contact. The outlet of the pump compartment can be closed by a check or nonreturn valve which closes in the direction of the pump compartment. The inlet of the blast nozzle is connected via a gas chamber with the outlet of the pump compartment, the outlet of the gas chamber confronting the blast nozzle can be closed by means of a further check or nonreturn valve which closes in the direction of the gas chamber. In the inlet of the gas chamber which confronts the pump compartment there opens a throughpassage emanating from the inlet of the blast nozzle, this throughpassage possessing a third check or nonreturn valve which opens in the direction towards the aforementioned inlet of the gas chamber.

    摘要： A fuel injection system is proposed which serves to supply fuel to an internal combustion engine. The fuel injection system includes a metering and quantity distributing valve connected with regulating valves, which can be acted upon by the fuel pressure in a differential pressure control line. Communicating with a fuel supply line are a pressure limiting valve and a switch member, the latter having a switch diaphragm which is displaceable into a return flow chamber by the fuel pressure counter to a switch spring and a closing spring. Upon this displacement, via a tappet, a spring plate resting on the switch diaphragm opens a sealing valve, which rests at the mouth of an outflow line, which via a control throttle leads to the differential pressure control line. The pressure limiting valve is located upstream of the sealing valve. The return flow chamber is arranged to communicate with the fuel container via a return flow line.

    摘要： An injection valve for fuel injection systems in internal combustion engines which comprises a movable valve element cooperating with a valve seat disposed in a nozzle body, with a guide bore provided downstream of the valve seat. A swirl insert is partially compressed in the guide bore and disposes open swirl channels in the direction of its circumference. The swirl channels extend in an axial direction from one end of the swirl insert to the other, are slanted toward the longitudinal shaft of the injection valve and discharge in a tangential direction into a preparation bore. The swirl channels serve simultaneously as metering channels whose throttling length is adjustable by displacing the swirl insert inside the guide bore.

    摘要： A fuel injection nozzle of the type which includes an outwardly opening valve needle of a valve group and an inner longitudinal bore connecting the valve group with a fuel inlet to the nozzle. The longitudinal bore includes a narrow section between two larger sections, the two larger sections being thus decoupled from pressure variations in either section.

    摘要： A high-voltage, blast-actuated power switch is disclosed in which field electrodes are included in order to prevent arcing within the switch after a bridge conductor has been blasted. The field electrodes are arranged coaxially about the bridge conductor, and are each electrically connected to one of two external connections. The field electrodes include opposing ends which are rounded and which are separated from each other by a distance which is smaller than the distance between the separated ends of the bridge conductor that are bent back onto internal elements of the external connections when the bridge conductor is blasted. The field electrodes tend to reduce the influence of the sharp edges formed on the separated ends of the bridge conductor when the bridge conductor is blasted, thereby increasing the breakdown voltage between the external connections and increasing the dielectric strength of the switch. An alternate embodiment of the present invention includes a floating electrode which is arranged between the opposing ends of the field electrodes.

    摘要： A method for finishing surfaces of workpieces includes a honing process with at least two method steps. In one of the method steps the surface, for example, the inner wall of a bore, is honed to a predetermined final dimension whereby a very fine structure with minimal depth of honing traces is generated so that a great portion of the surface functions as the supporting surface. In a further method step, which can be performed before or after the finishing-honing step, crossed grooves are provided in the surface by subjecting the surface to a stream of a medium, especially a laser, whereby the pattern of the grooves provides a lubricant reservoir for the future use of the workpiece. The treatment with a stream of a medium does not cause deformations at the edges of the grooves. This ensures an optimal distribution of the lubricant.
