P 11327 XII147 f Patent 911 798 relates to a hose connector in which a conical socket is attached to a connection nipple by means of a union nut and a ring made of flexible, preferably elastic material corresponding to a dog that is connected to the socket cone is arranged and is characterized by (IaIi the ring in an annular groove of shallow depth arranged directly in front of the dog and the axial lung of the unstrained ring is somewhat larger than the distance χ between the dog and the face of the nipple that is established after tightening the union nut. The Krfmdung concerns an improvement of the Proposal according to the main patent and is characterized by the fact that the dog turned away The boundary wall of the annular groove has an abutment adjoining the tulle cone and dal.! made of a highly elastic plastic. Abrasion resistance, z. H. a networked one Polyester plastic, to be ordered sealing ring on the front side facing the dog on the inside edge a training adapted to the professionalism of the university and on the edge of the air a slight inward has curved bevel, such that a see in (cross-section approximately wedge-shaped tapering Ringüppe is formed, which in the untensioned state of the ring on the rounding of the Ring groove rests. This training ensures that the annular lip is pressed together axially of the sealing ring while tightening the union nut with the weak inwardly curved bevel close to the inner surface of the conical recess of the connection nipple .r.r and the compressed air that grips the lip creates a kind of lip seal arises, which ensures a secure sealing of the compressed air against the nipple. Through the cramp one made of highly elastic plastic Abrichfestigkeil existing sealing ring occurs in this mode of operation even after a long period of use no leakage due to wear and tear one. In the Avr drawing the (! Object of the Lrfin- (is shown, for example. Ls shows l'ig. 1 a slippery gauze in partially cut I. longitudinal view, Lig. J a partially sectioned longitudinal view J _{0 of} the Kegelti'ille in the untensioned state of the sealing ring, Fig. 3 shows a section through a sealing ring. Hei the hose connection according to FIGS. 1 and 2 a dog 2 is provided at the shop of the Tüllenkegcls 1. Immediately in front of the dog 2 is in the Spout cone incorporated an annular groove 3, the limit wall of which is turned towards the dog the Tülleiikegel subsequent rounding 9 has. In the annular groove 3 is made of wetted poly (M estersplastic with high elasticity and abrasion-resistant wedge existing sealing ring.) is used, which is on the face facing away from the collar on the Inner edge a cavity adapted to the cross-section of the groove and a weak one on the outer edge inwardly curved chamfer 10 has. Due to the inwardly curved bevels on both sides on the end face of the sealing ring 4 facing away from the collar, a cross-section is approximately wedge-shaped annular lip 11 formed, which in the unstrained state of the ring flat on the Rounding 9 of the annular groove 3 rests. On the rear linden tree 5 of the spout is a Hose attached. The sleeve cone becomes through the union nut 6 engaging behind the collar 2 clamped with the connection nipple 7. This nipple 7 has a conical enlarged bore in which the tulle cone engages sealingly. Between the end face 8 of the nipple 7 and the opposite one Surface of the collar 2 becomes the sealing ring 4 during the establishment of the connection the tightening of the union nut 6 is compressed in the axial direction, the annular lip 11 with the bevel 10 to the conically expanded Inner surface of the connection nipple 7 applies. This causes the compressed air to reach under the ring lip and ensures that the compressed air is permanently sealed against the nipple. The distance χ between the end face of the connection nipple 7 and the nozzle collar 1 is slightly smaller than the axial length of the sealing ring 4 when the union nut is tightened. Crosslinked polyester plastics include, in particular, such thermoplastics understood what kind of crosslinked polyurethanes from a condensate of Lsozyanaten with Polyesters are made. Such polyester plastics are preferably used for the stated purpose in question, \ velche stimulated to polymerize by peroxide catalysis in the presence of styrene will. In addition to such polymerization products, there are also polycondensation or polyaddition products suitable, with a high elasticity and high abrasion resistance in all cases arrives.
