  • HYDRAULIC STEERING
    Publication number: 20070251755
    Abstract: The invention concerns a hydraulic steering with a steering motor arrangement having at least one steering motor, and with at least two steering circuits, each having a steering valve that interrupts a path from a pressure supply to the steering motor arrangement in the neutral position and releases a path from the pressure supply to the steering motor arrangement on a movement out of the neutral position. It is endeavoured to simplify the embodiment of such a steering. For this purpose, the steering valve (5a, 5b) has two end positions, one on each side of the neutral position, in which positions a path from the pressure supply (15, 21) to the steering motor arrangement (2) is interrupted.

  • Object having a layer of conducting material forming a sensing device
    Publication number: 20070234818
    Abstract: An object comprising a body part having an electrically insulating outer surface part, and a first layer arranged on the outer surface part. The first layer is formed by one or more electrically conducting materials and defines one or more conducting paths between a first area of the outer surface part and a second area of the outer surface part. Thereby electrical signals may be transferred between the first and second area parts. The layer further defines a sensing device, which is thereby embedded into the object. The object is provided with a threaded portion defining an outer thread. Thereby the object may easily be fitted into an opening having a mating inner thread. The object may be in the form of an ordinary bolt with a sensing device embedded in a surface part thereof.

  • Nozzle for air-assisted atomization of a liquid fuel
    Patent number: 7273187
    Abstract: A nozzle (100) for air-assisted atomizing of a liquid fuel comprises a fuel feed passage (110) and an air feed passage (114) and a swirling chamber (118) from which fuel and air may be passed to an exit orifice (126) for emerging a cone shaped spray. An air bypass passage (122) is provided for leading a fraction of the air flow in the air feed passage (114) past the swirling chamber (118) and to an air exit (124) arranged such with respect to the exit orifice (126) that, during operation of the nozzle, air emerging through the air exit (124) reduces depositing of residues of fuel on a downstream surface (130, 132, 136) of the nozzle element (108). Grooves or other flow-guiding elements may confer swirling or rotation of air in or downstream of the air feed passage (114) and/or the air bypass passage (122).
