  • Vibration isolator
    Patent number: 4222029
    Abstract: A vibration isolator is connected in line between an air intake tube (22) of an engine (14) and a pressure-responsive switch (30) to isolate the pressure-responsive switch from vibration during operation of the engine. The isolator includes a pair of metallic coupling members (52, 54) connected together by a resilient tube (50) providing fluid communication between the air tube (22) and the pressure-responsive switch (30). A conductive wire is disposed within the resilient tube for electrically connecting the switch in its associated indicator or warning light (32) circuit.
