Abstract
An expansion chamber device for clutch pedal vibration attenuation includes a cylindrical body having an inlet line integrally connected to and penetrating through a first end wall of the body. At an opposite end of the body from the first end wall is a discharge line integrally connected to and penetrating a second end wall of the body. A diameter of the expansion chamber device is approximately 3.8 cm and a length of the expansion chamber device ranges between approximately 10.2 cm to 15.2 cm. The expansion chamber device reduces vehicle and engine vibrations in a path including a clutch pedal over a frequency range between approximately 50 Hz to approximately 225 Hz.
