Patent number: 5632447Abstract: 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.Type: GrantFiled: August 1, 1995Date of Patent: May 27, 1997Assignee: Robert Bosch GmbHInventor: Wilhelm Christ

Patent number: 5172443Abstract: In a method for wet-finishing textile goods in the extraction process, the textile goods are made-up in the form of spools or in packages. They are placed in this made-up form in a vessel closable in a pressure-tight manner and the air is then at least substantially removed from the interstices in the textile goods. In the course of the method, the liquor present in the form of an aerosol is made to flow through the textile goods. In order to reduce the water and energy consumption and to also improve the quality of the treatment, the textile goods are first transferred to a state with increased temperature and low residual moisture. Subsequently or or simultaneously, the air is at least substantially removed from the interstices in the textile goods, and after this state has been attained, a gaseous medium under increased pressure which together with the liquor forms an aerosol is made to flow directly through the textile goods.Type: GrantFiled: March 6, 1991Date of Patent: December 22, 1992Assignee: Then Maschinen und Apparatebau GmbHInventor: Wilhelm Christ

Patent number: 4947660Abstract: 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.Type: GrantFiled: October 3, 1989Date of Patent: August 14, 1990Assignee: Hoechst AktiengesellschaftInventors: Hans-Ulrich von der Eltz, Wilhelm Christ

Patent number: 4903509Abstract: In industry there is, for economic reasons, an urgent need to be able to carry out the drying of moist textile material immediately after a completed wet-treatment in the same apparatus in which the preceding treatment operation was carried out.According to the invention the problems arising in the case of textile materials treated in rope form on jet units are solved by evaporatively dewatering the textile material in rope form by means of the gaseous agent which in the case of fabric-advancing jet systems operated by flowing liquor, steam or hot air takes over the transport of the goods immediately after the wet-treatment and which acts on the textile material under a predetermined variable superatmospheric pressure, then cooling the circulating drive gas to condense out the absorbed moisture, and recirculating the air thus dried.Type: GrantFiled: February 19, 1988Date of Patent: February 27, 1990Assignee: Hoechst AktiengesellschaftInventors: Wilhelm Christ, Hans-Ulrich von der Eltz

Patent number: 4862546Abstract: Process and apparatus are provided for the batchwise wet treatment of textile material with an aqueous liquor that contains dyestuff or other textile processing products according to an exhaust technique. Textile material in continuous loop form is recirculated in a jet dyeing machine, and a recirculating gas stream propels the material. A blower recirculates the gas stream while aqueous liquor is metered into the stream by aspirating the liquor at the upstream side of the blower. The action of the blower finely disperses the liquor within the gas stream.Type: GrantFiled: July 20, 1988Date of Patent: September 5, 1989Assignee: Hoechst AktiengesellschaftInventors: Hans-Ulrich von der Eltz, Wilhelm Christ

Patent number: 4862545Abstract: 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.Type: GrantFiled: July 20, 1988Date of Patent: September 5, 1989Assignee: Hoechst AktiengesellschaftInventors: Hans-Ulrich von der Eltz, Wilhelm Christ
