RESONATOR CONNECTION HOSE FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a resonator connection hose capable of obtaining the vibration absorbing effect and surely securing the resonator effect. SOLUTION: In a connection hose 7 to connect a resonator to a throttle body, the resonator effect is secured by providing a cylindrical hose whose inner surface is smooth and whose inner diameter is little changed, the vibration absorbing effect is secured by forming annular ribs 8 in parallel with appropriate pitch intervals on the outer circumferential surface to reduce the wall thickness and to facilitate the elastic deformation, and the resonator effect is secured by securing the rigidity to the pressure pulsation by the annular ribs 8.
