    摘要： An active carbon filter intended for the fuel supply system of the internal combustion engine of a vehicle consists of a housing (1), inside of which flow paths for the different operating states of the filter are established between the ports (10, 11, 12) for connection with the top space of a tank, the ambient atmosphere and the intake manifold of the internal combustion engine. Proceeding from the port (11), these flow paths are characterized by chambers situated one in back of the other for pre-warming the air, an adjacent chamber (22) equipped with a first heating unit, an adjacent chamber (23) that accommodates active carbon particles, and another, adjacent chamber (28) that accommodates active carbon particles, is equipped with a second heating unit (34), and is provided with the ports (10, 12). This yields the establishment of optimal, in particular thermal conditions for the regeneration of the active carbon particles.

    摘要： An ultrasonic flow sensor for use in a fluid medium is described. The ultrasonic flow sensor includes at least two ultrasonic converters which are situated in a flow tube offset relative to one another, longitudinally with respect to a flow of the fluid medium. The ultrasonic flow sensor also includes a reflection surface, the ultrasonic converters being set up to exchange ultrasonic signals via simple reflection on the reflection surface. In addition, a deflection device is provided between the ultrasonic converters which is set up to essentially suppress parasitic ultrasonic signals, which are reflected from the reflection surface and which strike the deflection device, by deflection away from the ultrasonic converters.

    摘要： A fuel vapor storage and recovery apparatus includes a fuel vapor storage canister, said fuel vapor storage canister comprising at least first and second vapor storage compartments filled with an absorbent material, for instance filled with activated carbon, at least a vapor inlet port, an atmospheric vent port and a purge port. Said fuel vapor storage canister defines an air flow path between said vapor inlet port and said atmospheric vent port during shut-off of the internal combustion engine of the vehicle. During purging cycles there is defined an air flow path between said atmospheric vent port and said purge port wherein said first and second vapor storage compartments are arranged in concentric relationship and wherein said first and second vapor storage compartments in flow direction are separated from each other by an air gap diffusion barrier.

    摘要： An ultrasonic flow sensor, in particular for determining the flow velocity of a medium flowing through a pipeline, has at least one ultrasonic converter for transmitting and/or receiving ultrasonic signals, an oscillator, which is connected with the ultrasonic converter, and an evaluation unit, which determines a phase shift of the ultrasonic signal that was received, with respect to a reference signal. The evaluation unit includes a plurality of quadrature demodulators, which operate with different demodulation frequencies and each determine phase information about the ultrasonic signal that was received, and when a vernier unit is provided, which determines—based on the individual pieces of phase information—a phase angle or a quantity proportional thereto.
