Abstract
PURPOSE: To prevent rubber hose from kinking at the using time under pressure by making fiber total reinforcing ratio at internal and external reinforcing layers to be 1:1.1W1.3.
CONSTITUTION: This pressure withstanding rubber hose is constituted by making selection within the bounds of 1.1W1.3 times the twist yarn driving piece number of the internal reinforcing layer 4 in proportion to the thickness of intermediate rubber 3 through the twist yarn driving piece number of the external reinforcing layer 5 in the structure of having a pair of internal and external spiral reinforcing layers 4 and 5 convolved the lead direction in diametrically opposing direction in the middle of an inner tubular rubber 1 and an outer coating rubber 2 partitioned off by an intermediate rubber 3 at mutually different convolving diameters. Concretely speaking, when 12 pieces is secured for the driving piece number of the twist yarn 4' at the internal reinforcing layer 4 while 14 pieces is for the driving piece number of the twist yarn 5' at the external reinforcing layer 5 likewise, in case of such a rubber hose, not to mention in case where the internal pressure may stand at 50kg/cm2 at the time of using, even in case where the internal pressure may at 100kg/cm2 at the time of using under probational pressure, any kinking is not found.
