Brian P. Dondlinger 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).

  • Crankcase of an engine
    Patent number: 7444979
    Abstract: The present invention provides a motorcycle including a front wheel, a rear wheel, a frame supported by the front and rear wheels, a crankcase including a first interface portion and a first passageway exposed to the first interface portion, a reservoir located remotely from the crankcase adapted to contain a lubricant, and a transmission case supported by the frame and including a second interface portion and a second passageway exposed to the second interface portion. The second passageway is in fluid communication with the reservoir. The first interface portion is coupled to the second interface portion. The first passageway is in fluid communication with the second passageway. The first and second passageways provide fluid communication between the reservoir and the crankcase through the first and second interface portions.
    Type: Grant

  • Primary housing assembly for a motorcycle engine
    Patent number: 7395799
    Abstract: A primary housing for a motorcycle engine includes an inner housing that defines internal coupling apertures, transmission coupling apertures, and external coupling apertures. Internal fasteners extend through the internal coupling apertures and the transmission coupling apertures to couple the inner housing to the crankcase and the transmission. An outer housing defines coupling apertures that align with the external coupling apertures and fasteners extend through the coupling apertures, through the external coupling apertures, and into the engine crankcase to couple the inner and outer housings to the crankcase. A resonant damping device is rigidly or moveably coupled to an anti-node region of the outer housing to reduce noise emissions from the outer housing during engine operation.
