  • Patent number: 5613523
    Abstract: The invention is directed to a hot water resistant pressure hose (1) comprised of an inner tubing (2) made of an elastomer safe for use with food, preferably silicone, whose outer surface (3) has wound around it a plurality of multifilament polyester yarns (7, 8) forming a braid structure (4). This results in a braiding (4) having meshes (6) for establishing a positive-engagement bond between the inner tubing (2) and an outer tubing (9) made of an elastomer, preferably silicone, that is applied to the braiding (4). The outside diameter D of the inner tubing (2) is smaller than or equal to 6 mm, preferably 4.7 mm. For each winding direction, 10 to 15, preferably 12 polyester yarns (7, 8) are used, with the polyester yarns (7, 8) having a diameter that results at a weight of 250 den, minimum, and 310 den, maximum, preferably 280 den. Further, each mesh (6) is to cover an area of between 0.25 mm.sup.2 and 2.25 mm.sup.2, preferably 1 mm.sup.2. A pressure hose (1) is obtained which is hot water resistant (95.
