摘要:
An apparatus for the treatment of strand-shaped textile products in the form of a continuous material strand which is circulated at least during part of the treatment, includes an elongated, essentially tubular treatment container and a transport nozzle array that can be charged with a gaseous transport medium stream. In the treatment container is arranged, adjoining a material strand inlet, a storage section for receiving a piled-up material strand package corresponding a sliding floor that is inclined, at least in sections, in a manner descending from pile-up means toward a head part of the treatment container. In the region of the transport nozzle array means are provided in order to charge the material strand at least in the region of the transport nozzle array with a liquid treatment agent.

In the textile industry there is a constant need for processes where the textile material to be treated can be treated in a simple form, for example in rope form instead of in the open-width state, and continuously. According to the invention, this need is met when the textile material is introduced via pressure seal elements into a specially constructed jet dyeing machine, is impregnated there with treating liquor during entry or immediately thereafter and is conveyed further in the machine by means of at least one jet operated by means of a gas stream, the treating agent applied, preferably dye, having advantageously been subjected to fixation in the course of the presence in the gas atmosphere. The necessary physical conditions (pressure, temperature) for this are created by the driving gas. Moreover, in the course of the passage of the textile material it is possible to carry out a further, including a completely different, impregnation.

The invention relates to an injection valve member for a fuel injector, which injection valve member is of multi-part design and which has different functional regions. To reduce the production costs for a fuel injector having an injection valve member, the injection valve member includes two guide bodies which are fastened to a separate connecting rod.

In a method for treating ropelike textile goods in a closed container that contains at least two axially adjacent J-boxes for receiving textile goods during at least part of the treatment time, a driving motion in a feeding direction is imparted to the textile goods, by means of a gaseous flow of feeding medium made to act on the rope via feed nozzle means. The textile goods, before entering each J-box, pass through separate feed nozzle means assigned to that J-box. Upon exiting from these feed nozzle means, the textile goods are introduced selectively into the respective associated first J-box or a second J-box adjacent to this J-box, or in the case of at least one J-box are conducted along a predetermined path, which carries the textile goods away from this J-box.

A fuel injection nozzle for preinjection and main injection has a nozzle holder in which two closing springs are arranged coaxially, one spring acts continuously on the valve needle via a central pressure bolt and the other spring acts on the valve needle, via a pressure ring surrounding the pressure bolt, once the valve needle has passed through a pretravel (h.sub.v). Between the valve needle and the pressure bolt and the pressure ring, an intermediate pressure element which is constructed as a disk is arranged, the outer edge area of the intermediate pressure element does not come into contact with the pressure ring until after the valve needle has passed through the pretravel (h.sub.v), which pressure is supported in the closed position of the valve needle by a shoulder of an intermediate disk. In order to prevent the connection between the low pressure space at the valve needle and the pressure-relieved spring chamber being interrupted in the pretravel position when the intermediate pressure element comes into axial contact with the pressure ring which is supported on the shoulder of the intermediate disk, bridging channels are arranged at least in the intermediate pressure element.

After a dyeing operation has been concluded, the hot dyeing liquor present in the piece dyeing jet is returned via a cooling heat exchanger in the dyeing circulation system back into the makeup storage vessel for the dyeing liquor. Thereafter, the liquor-free dyeing system, which is still under an elevated static pressure, is relieved to atmospheric whereby the dyeing system is cooled down adiabatically together with the dyed textile material present therein to such an extent that a sample can be taken therefrom rapidly and safely.

Inventive considerations have shown that the use of shorter liquid ratios can be realized in the course of wet-treating textile ropes in jet dyeing machines if the textile goods are driven by means of a non-inert gas stream and the dyestuff or product formulations necessary for carrying out the type of treatment desired are brought into contact with the goods by atomization into the circulated gaseous driving agent.

An apparatus for wet-processing strand-shaped textile good, includes a closed container, a transport nozzle array to which a gaseous transport medium can be supplied, and a device for applying a liquid treatment agent in atomized form to the moving strand of goods in the region of the transport nozzle arrangement. The device for the application of the treatment agent is designed to apply the treatment agent to the strand of goods in two sections (I, III), which are at a distance from each other in transport direction of the strand of goods, in a form enclosing the strand of goods at least partially in a ring-shaped manner. In so doing, the gaseous transport medium is applied to the strand of goods in an intermediate region (II) located between said two sections.

The invention relates to a method for producing an injection valve for liquids, preferably an injection valve for injecting fuel into a combustion chamber of an internal combustion engine. The injection valve has a valve body, with a valve seat which is formed therein, and a valve needle which interacts with the valve seat in order to open and close at least one injection opening. The injection valve is produced by means of the following method steps: producing the valve body from steel, hardening the valve body, annealing a partial region of the valve body at an annealing temperature. The device for carrying out the method according to the invention has an inductive annealing generator which generates a suitable alternating current for operating a coil, in the magnetic field of which coil the valve body can be heated for annealing.
