Abstract
A hose with a one-way valve used in a brake actuating system for automobiles. A one-way valve unit is housed in a flexible hose for connecting a booster shell of a servomotor with an intake manifold of the internal combustion engine so as to prevent leakage of vacuum. A valve housing receives therein a valve member and a valve spring thereby forming the one-way valve unit. The housing further has a valve seat, a cylindrical guide portion and an annular seal projection of diameter larger than the guide portion. A fastening band is provided on the outer periphery of the hose to prevent movement of the one-way valve and is marked with a mounting direction of the hose.
