Patent number: 7641133Abstract: The invention relates to a cleaning lance with a nozzle tube (1), on whose outlet-side end there is a discharge nozzle (2), which can be switched by means of a switching mechanism between a high-pressure position and a low-pressure position. In order to be able to perform both the foam application and also the high-pressure wash with such a cleaning lance, without requiring manual switching of the operating function on the cleaning lance itself, it is provided that the nozzle tube (1) has an air inlet (3), which can be closed with a valve (4), wherein the valve function is coupled to the switching mechanism of the discharge nozzle (2), such that the valve (4) closes the air inlet (3) when the discharge nozzle (2) switches from its low-pressure position into its high-pressure position.Type: GrantFiled: August 13, 2005Date of Patent: January 5, 2010Assignee: Washtec Holding GmbHInventor: Marcus Wilfert

Patent number: 7635093Abstract: A fuel injector, in particular a fuel injector for fuel-injection systems of internal combustion engines, includes a piezoelectric or magnetostrictive actuator which is excitable via an electrical line and actuates a valve-closure member arranged in a housing, the valve-closure member cooperating with a valve-seat surface to form a sealing seat, and an hydraulic coupler. The hydraulic coupler is fixedly arranged between the actuator and a valve-assembly that includes the valve-closure member and the valve-seat surface.Type: GrantFiled: January 23, 2004Date of Patent: December 22, 2009Assignee: Robert Bosch GmbHInventor: Hubert Stier

Patent number: 7628342Abstract: A liquefied gas dispensing nozzle having a cylinder with its axis in a vertical direction, and a plug to be inserted into the cylinder from above as its main elements. A plurality of slit portions for letting through the liquefied gas are formed in parallel in an axial direction of the cylinder from the upper end to the lower end in an inner circumferential face of the cylinder contacting to an outer circumferential face of the plug. A width of at least one or more pair of mutually opposed slit portions is generally constant from its upper end to lower end and its slit bottom is inclined so that the depth of the slit becomes gradually shallower from upper end to lower end. Each slit portion of the cylinder is closed with the plug when the plug, which is movable vertically relative to the cylinder, reaches the lowest end position. A rounded portion formed by rounding a corner portion of the lower end of the slit portion includes an inclined slit bottom.Type: GrantFiled: May 11, 2004Date of Patent: December 8, 2009Assignee: Daiwa Can CompanyInventors: Yoshimichi Shimoda, Masami Matsunaga, Nobuyoshi Aoki, Nobushige Wakana, Hirokazu Murai

Patent number: 7617996Abstract: A spraying head for bathing comprises an outer housing and an inner housing. In a center of a top edge of the outer housing is mounted a locking seat having plural water outlet openings and outer threads, and an engaging section mounted with a water-stop ring is formed on a lower end of the locking seat. The inner housing is mounted in the outer housing, and the inner housing is combined with a water outlet panel and is mounted with a locking assembly having inner threads and an abutting flange. The inner threads of the locking assembly are threaded with the outer threads of the locking seat in such a manner that the abutting flange is abutted against the water-stop ring, so as to form a sealing condition. And a bolt cooperates with a spacer and a nut enabling the water outlet panel to fix in the locking seat.Type: GrantFiled: December 7, 2006Date of Patent: November 17, 2009Assignee: Ching Shenger Co., Ltd.Inventor: Chin-Tsai Lee

Patent number: 7581686Abstract: A fuel injector for the injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle guided in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle is retained in sealing contact against a valve-seat surface. Formed at a downstream-side end of the fuel injector is a projection which projects beyond the valve-closure member of the fuel injector.Type: GrantFiled: August 22, 2002Date of Patent: September 1, 2009Assignee: Robert Bosch GmbHInventors: Volker Holzgrefe, Günther Hohl, Michael Hübel, Jürgen Stein

Patent number: 7568635Abstract: A system and method is provided for atomizing a liquid without the use of air to atomize the liquid. The system comprises a turbo spray nozzle that has a rotatable shaft. The rotatable shaft has a center bore with an opening at one end to enable a liquid to flow into the center bore of the rotatable shaft. The rotatable shaft also has a plurality of orifices that extend from the center bore to an outer surface of the rotatable shaft at the end opposite the opening. The rotatable shaft is rotated by pressurized air. The rotation of the shaft causes the liquid flowing into the center bore to be induced into a helical flow path that causes the liquid to disassociate. The system may comprise a spray gun coupled to the turbo spray nozzle. The system may also comprise an air compressor to provide the pressurized air to rotate the rotatable shaft. The system may also comprise a container for the liquid hat may be pressurized to provide a motive force to the liquid.Type: GrantFiled: September 28, 2004Date of Patent: August 4, 2009Assignee: Illinois Tool Works Inc.Inventor: Paul R.
