Title: Verfahren zur bestimmung des raildrucks eines einspritzventils mit einem piezoelektrischen aktor
Inventor: RUEGER JOHANNES-JOERG
IPC: F02D41/20
Filed: 2001-01-17
Abstract: Erfindungsgemäss wird ein Verfahren zur Bestimmung des Raildrucks eines Einpritzventils mit einem spannungsgesteuerten piezoelektrischen Aktor vorgeschlagen, wobei der piezoelektrische Aktor (2) mittels eines hyrdaulischen Kopplers (4) eine Düsennadel (11) betätigt. Durch den Druck im Hochdruckkanal (13) wird über den hydraulischen Koppler (4) ein Kopplerdruck (Pk) aufgebaut, der in dem Aktor (2) eine Piezospannung (Ui) induziert. Da dieser Spannungswert redundant ist zum Druckwert im Hochdruckkanal (13), der von einem Drucksensor (D) gemessen wird, kann er zur Überwachung der Funktion des Drucksensors (D) verwendet werden. Bei Ausfall des Drucksensors (D) kann mit Hilfe der induzierten Spannung (Ui) ein Notlaufbetrieb für das Einspritzventil (1) aufgebaut werden. Das Einspritzventil (1) dient vorzugsweise zur Kraftstoffeinspritzung in einem Verbrennungsmotor.

Abstract: The invention relates to a device for driving a plurality of shafts on a flap system, which are arranged on one plane in a mounting device, whereby the flaps may be rotated in both directions. Said device comprises a drive shaft for driving a first connecting rod, connected by means of a plurality of lever arrangement to the plurality of shafts, whereby the lever arrangements are each connected to a first axle in the end region thereof, each of which is rotatably mounted in a bearing in the connecting rod and in the other end region thereof said lever arrangements are fixed to a shaft, each of which is rotatably mounted in a bearing in the mounting device. A bi-directional endless drive of the flap shafts of a flap system is thus achieved by means of a simple, robust and low-maintenance construction, whereby at least one further connecting rod is provided, the lever arrangement of which is fixed at a pre-determined angle, relative to the lever arrangement of the first connecting rod.

Abstract: The invention relates to an airbag system (1) comprising a housing, an airbag accommodated therein, and a gas generator (3). The gas generator (3) is accommodated inside a chamber (4) separated from the airbag. A connecting opening (12) exists between the chamber (4) and the airbag. In addition, the chamber (4) has another opening (13) that points away from the airbag. These openings (12, 13) are, depending on the state of the airbag system (1), closed or opened by a control slide (6) that can move inside the chamber (4). When the airbag system (1) is in an idle state, the opening (12) pointing toward the airbag is largely closed, whereas the other opening (13) is opened. In this state, gas generated by the gas generator (3) thus does not flow into the airbag but out of the chamber (4). The control slide (6) remains in this state if an  out of position  situation is determined. Otherwise, the control slide (6) is displaced inside the chamber (4) in order to open the opening (12) to the airbag thereby enabling the airbag to fully deploy. The displacement of the control slide (6) is effected, for example, by means of rebound straps.

Title: Downward flow cyclone - with inlet duct shaped to assist downward motion
IPC: B04C5/04
Filed: 1970-10-09
Abstract: A downward flow cyclone with tangential inlet into a vortex chamber, and axial outlet pipe for the lighter phase of the mixture and with a top cover plate extending from the cyclone wall inwards towards the central outlet pipe, is constructed with the top plate of the inlet duct inclined downwards and inwards the central outlet pipe, is constructed with the top plate of the inlet duct inclined downwards and inwards towards the central axis (i.e. approximately transverse to the flow direction through the duct); the top cover plate of the vortex chamber also slopes downwards from the outer upper edge of the inlet duct in the same direction as the top plate of the inlet duct and at the same inclination. Specif. the amount of fall of the slope across the diameter of the chamber is the depth of the inlet duct. The advantage of the arrangement is that downward flow is assisted by the shape of the inlet duct and top plate of the chamber without the necessity for complicated, e.g. helical, construction.
