Publication number: 20130112767Abstract: A common rail fuel injector includes a needle valve member that moves to open and close nozzle outlets for a fuel injection event responsive to pressure in a needle control chamber. Between injection events, the needle control chamber is fluidly connected to the fuel inlet by a first pathway that includes a Z orifice, and fluidly connected to the fuel inlet by a second pathway that includes an F orifice, an intermediate chamber and an A orifice. During an injection event, the needle control chamber is fluidly connected to a drain outlet by a third pathway that includes the A orifice, the intermediate chamber an E orifice and a buffer chamber, which may assist in avoiding cavitation erosion in a sensitive area associated with a flat control valve seat. Different performance characteristics are achieved by adjusting the sizes of the respective of F, A, Z and E orifices.Type: ApplicationFiled: November 7, 2011Publication date: May 9, 2013Applicant: CATERPILLAR INC.Inventors: Sana Mahmood, Zhenyu Li, Michael Curtis Herr, Gregory William Hefler, Linda Angharad Williams

Publication number: 20130112768Abstract: A tanker vehicle for distributing liquid on a surface includes a chassis that supports a tank for holding the liquid. A fluid pump discharges the liquid from the tank and is driven by a hydraulic motor. A hydraulic system delivers hydraulic fluid to the motor through a supply line and returns the fluid to a tank through a return line. A bypass circuit is disposed between the supply line and the return line, bypassing the motor. The bypass circuit includes a system for providing a combination soft start and soft stop of the hydraulic motor that is configured to enable hydraulic fluid to flow from the supply line through the bypass circuit to the return line at a start of the hydraulic system and to flow from the return line through the bypass circuit to the supply line at a shutdown of the hydraulic system.Type: ApplicationFiled: October 25, 2012Publication date: May 9, 2013Inventor: LeRoy G. Hagenbuch

Publication number: 20130067656Abstract: The invention relates to a method and a device for generating a nanoaerosol, wherein at least one fluid to be atomized is atomized in a nozzle via a nozzle opening of the nozzle along a discharge direction in the form of fluid particles, the atomized fluid particles are deflected from the discharge direction and larger fluid particles are at least partially separated from smaller fluid particles, the separated larger fluid particles are returned to the fluid to be atomized and the smaller fluid particles are dispensed onto the environment. A cartridge in which the nozzle and the fluid to be atomized are arranged is used. According to the invention, a stream of a carrier gas is generated in the nozzle and at least one fluid to be atomized is brought into contact with the carrier gas.Type: ApplicationFiled: June 17, 2010Publication date: March 21, 2013Applicant: MEDIC ACTIV VERTRIEBS GMBHInventors: Peter Brunner, Hans Peter Zarfl, Bernd Heiko Lindena
