Abstract: A flexible tube assembly includes a metal tube having large diameter portions and small diameter portions positioned alternately along a longitudinal axis of the metal tube; a wire braiding mounted around the metal tube; a first ring fitted in one of the small diameter portions of the metal tube; a second ring positioned to secure the wire braiding around the first ring; a first annular member and a second annular member positioned on opposite sides of the first ring and the second ring, the first annular member and the second annular member being configured to be assembled by approaching toward each other along the longitudinal axis and, in an assembled condition, at least one of the first annular member and the second annular member surrounds cut wire ends of the wire braiding unexposed.

Abstract: A flow rate control unit includes (a) a housing including a hollow cylindrical wall configured to form a flow passage, an upstream wall, a downstream wall, an inlet opening, and an outlet opening; (b) a valve member disposed inside the cylindrical, configured to move between a most upstream position and a most downstream, the valve member including a pressure receiving portion that faces the inlet opening; and (c) an elastic biasing member (d) The valve member or the cylindrical wall forms a first guide passage. (e) The valve member forms a second guide flow passage.

Abstract: A connector assembly for connecting a corrugated tube with a braid mounted on the periphery of the hose to a metal connector, comprises an inner sleeve mounted on the corrugated tube, and an outer sleeve mounted on the inner sleeve, the inner and outer sleeve cooperating with each other to hold the braid between the inner and outer sleeves. The inner and outer sleeves have respective inner and outer tapered surfaces. One of the inner and outer tapered surfaces has one or more portions projecting toward the other of the inner and outer tapered surfaces.
