Patent number: 8449767Abstract: An oil reservoir having an oil inlet fitting and at least one oil outlet fitting for connecting to a hydraulic system. The reservoir comprising a housing having a lower housing part and a reservoir cover which is connected to the lower housing part and includes an integrated oil filter. An oil filler neck, which can be closed by a cap, is configured on the housing cover. The reservoir housing is equipped with at least one guide element which is attached to at least one inside wall of the reservoir housing and forms a circular guidance track for the oil. This guidance track forces the oil flow in a circular manner, after entering the reservoir and passing through the oil filter but before exiting the oil reservoir, such that any air which may be present is separated from the oil and can exit the oil reservoir via an air outlet.Type: GrantFiled: November 13, 2008Date of Patent: May 28, 2013Assignees: Robert Bosch GmbH, ZF Friedrichshafen AGInventors: Uwe Renner, Christoph Lipp, Rolf Karlstedt

Patent number: 8231714Abstract: A combined machine for pumping and separating into two distinct and purified phases a two-phase liquid/gas mixture or fluid, is provided. A first stage of the combined machine is equipped with an intake for the two-phase fluid, in which the two-phase fluid is sucked, pumped and partially separated into two distinct phases. One phase is mainly liquid and the other phase is mainly gaseous. A second stage of the combined machine includes two zones, which includes a first zone and a second zone. In the first zone, the mainly liquid phase extracted from the first stage is degassed. In the second zone, the mainly gaseous phase extracted from the first stage is dried. In a third stage of the combined machine, the degassed liquid is forced back and pressurized.Type: GrantFiled: December 21, 2009Date of Patent: July 31, 2012Assignee: Techspace Aero S.A.Inventors: Albert Cornet, Nicolas Raimarckers

Patent number: 7803216Abstract: A compact pressurized high-temperature gas cooler having superior heat exchange performance and excellent economical efficiency is provided. A return-flow structure is formed in which a flue through which high-temperature gas flows is formed in a pressure container, a heat exchanger is disposed in the flue, and a partition dividing the internal cross-sectional area of the flue is provided so that the high-temperature gas supplied from a bottom or a top portion of the pressure container flows back in a return direction. The cross-sectional-area division ratio dividing the internal cross-section of the flue is set so that the flow rate of the high-temperature gas flowing in one direction matches that flowing in the direction opposite thereto.Type: GrantFiled: December 22, 2006Date of Patent: September 28, 2010Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Yoshinori Koyama, Katsuhiko Yokohama, Osamu Shinada, Hiromi Ishii, Yuichiro Kitagawa, Kosei Manabe

Patent number: 6348087Abstract: A cyclonic separator is provided for separating a mixture containing three phases of mater into the constituent phases. The separator contains three concentric cylindrical chambers in fluid connection with each other. These three chambers are an upper chamber, a lower chamber, and an outlet chamber. Tangential fluid inlets and outlets are provided to minimize pressure loss across the separator. A radially disposed annular debris collector is located at the junction of the upper and lower chambers, and a gas support platform for directing gas out of the separator is disposed in the outlet chamber a sufficient distance from the debris collector so as to prevent turbulence adjacent the debris collector.Type: GrantFiled: January 10, 2000Date of Patent: February 19, 2002Assignee: Shaw Aero Devices, Inc.Inventor: David J.

Patent number: 6176903Abstract: A device for removing gases from fluids, in particular from a dialyzing fluid, includes a container, which in the position of normal use is provided with a bottom first orifice and a bottom second orifice. Disposed inside the container is a partition wall which divides the container into a first chamber having the first orifice and a second chamber having the second orifice. The partition wall extends from the container bottom up to near the container cover, forming a gap-shaped interstitial space between the first and second chamber, and the container cover. Provision is made in the container cover for a venting orifice that is sealed by a hydrophobic filter. In one preferred embodiment, the first and second chamber form a tube-in-tube arrangement. The device according to the invention allows for a high separation rate to be achieved with a compact and simple design.Type: GrantFiled: May 22, 1997Date of Patent: January 23, 2001Assignee: Fresenius Medical Care Deutschland GmbHInventor: Ralf Wamsiedler

Patent number: 6071331Abstract: Gas is separated from fluent material, particularly a liquid or a cellulose fiber suspension having a consistency of about 8-18%, utilizing a closed separation apparatus having a spiral housing with a central axis, a fluent material inlet channel, a fluent material outlet, and a gas outlet. A pressure differential is maintained between the inlet channel and the spiral housing, and the pressure differential is converted to kinetic energy of the fluent material by causing the fluent material to flow through one or more spiral flow paths through the inlet channel toward the spiral housing. In the spiral housing a rotor is rotated to impart a strong centrifugal force to the fluent material to cause gas to separate and collect adjacent the central axis of the spiral housing, from which the gas is removed. The strong centrifugal force caused by the rotating rotor discharges the fluent material through the outlet. The spiral flow paths rotate with the rotor in the spiral housing.Type: GrantFiled: June 1, 1995Date of Patent: June 6, 2000Assignee: Ahlstrom Machinery CorporationInventors: Toivo Niskanen, Kari Peltonen
