  • Publication number: 20200362845
    Abstract: A system for attenuating sound comprises an air compressor with an inlet, the inlet in fluid communication with an ambient environment. An inlet conduit extends from the inlet to the ambient environment, and an expansion volume is in fluid communication with the inlet conduit. A throttling valve or pressure relief valve is located between the expansion volume and the ambient environment, the throttling valve configured to regulate the flow of sound waves from the expansion volume, thereby attenuating the sound from the air compressor entering the ambient environment.

  • Patent number: 5875752
    Abstract: An improved engine gear drive train arrangement is provided which effectively minimizes the crankshaft torsional vibrations at the location of the gear train, for engines with a front gear train. A flywheel is resiliently connected to the rear end portion of the crankshaft so as to resiliently connect a driven unit to the crankshaft. An extra inertial device is connected to the front end portion of the crankshaft and includes an inertia so selected as to cause a nodal point of the first torsional vibration mode of the crankshaft to be located in the vicinity of the crank gear to minimize the amplitude of torsional deflection of the crankshaft at the crank gear. Also, the device for resiliently connecting the flywheel to the rear end portion of the crankshaft may include resilient members positioned in cavities formed by engaging rings.
