    • A high pressure resistant vibration absorbing hose with a bursting pressure of 5 MPa or higher has a hose body and a joint fitting. The joint fitting is to be attached to a swaged portion of the hose body. The hose body has an inner surface rubber layer, a reinforcing layer of high braid or winding density of 50% or more, and an outer surface rubber layer. The swaged portion is designed to have a larger diameter than the main portion of the hose body and the inner surface rubber layer has a wall thickness equal to or larger than 1.0 mm at a swaged portion in a state before the joint fitting is securely swaged thereto. The reinforcing layer has a braid or winding angle θ of a reinforcing wire member equal to or lower than a neutral angle 54.7° and higher than 48°.
    • 具有5MPa或更高爆破压力的高耐压振动吸收软管具有软管体和接头配件。 接头配件要连接到软管体的锻压部分。 软管体具有内表面橡胶层,高编织物或卷绕密度为50%以上的增强层和外表面橡胶层。 模锻部分被设计成具有比软管主体的主要部分更大的直径,并且内表面橡胶层在接头配件被牢固地铆合之前的状态下在锻压部分具有等于或大于1.0mm的壁厚 。 加强层具有等于或低于54.7°并高于48°的中性角的加强线构件的编织或卷绕角度θ。
