TIM DUENNWALD has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11260405
    Abstract: A ventilation module for a rail vehicle contains a housing having an air inlet, an air outlet, a dust discharge opening, a first cleaning station in an upper region of the housing, a cyclone separator which has a dust outlet and a cyclone air outlet. A second cleaning stage is disposed in a central region of the housing, which is arranged underneath the first cleaning stage such that air from the cyclone air outlet can reach the second cleaning stage. A dust discharge channel is connected to the dust outlet and is arranged in the central region. A dust discharge fan is set up to extract air and dust from the dust discharge channel and to remove the same through the dust discharge opening. A machine room fan is arranged in a lower region of the housing and is set up to extract air through the second cleaning station.

  • Patent number: 10835853
    Abstract: A rail vehicle or locomotive includes a machine compartment, a cooling air flow system supplying the machine compartment, and a separating device separating particles from the air flow. The separating device includes a cyclone separator, a raw air channel feeding a raw air flow with particles to the separator and a clean air channel leading a clean air flow away from the separator. The separator has a box-shaped housing having a plurality of cyclones penetrating the housing for separating particles from the raw air flow into the housing and a discharge opening discharging separated particles from the housing. The discharge opening is connected to a constricted section of a Venturi nozzle suctioning an exhaust air flow having discharged particles. The Venturi nozzle is connected to the raw air channel by a branching side channel. The vacuum at the discharge opening suctioning the exhaust air flow is compact and economical.
