Abstract
A vibration absorbing hose excellent in vibration absorbing property, mounting stability and shape retaining property. The vibration absorbing hose comprises at least one rubber layer composed of a rubber composition having a storage elastic modulus (E′) of 20 to 100 MPa at 200 Hz with an elongation strain of 0.1% at an ordinary temperature (about 20° C.), and a damping factor (tan δ) of not lower than 0.4.
Claims7
A vibration absorbing hose defined by an elongated hollow structure having means forming opening at opposite ends thereof for the conduct of mediums through said hose, said structure being constructed substantially entirely of rubber composition and comprising at least one layer composed of a rubber composition having a storage elastic modulus (E′) of 20 to 100 MPa at 200 Hz with an elongation strain of 0.1% at an ordinary temperature, and a damping factor (tan δ) of not smaller than 0.4.
A vibration absorbing hose defined by an elongated hollow structure having means forming openings at opposite ends thereof for the conduct of mediums therethrough, said structure being constructed substantially entirely of rubber composition and comprising a plurality of rubber layers, at least one of the rubber layers being composed of a rubber composition having a storage elastic modulus (E′) of 20 to 100 MPa at 200 Hz with an elongation strain of 0.1% at an ordinary temperature, and a damping factor (tan δ) of not smaller than 0.4.
