  "abstract": "The periphery of the portion of the valve body of a tire valve which is located on the outside of the wheel rim is composed of elements which are elastic in transverse direction and rigid in longitudinal direction. Tightness is assured by a sealing joint. The valve body may be of a single piece or of two pieces.",
  "claims": [
    "1. A tire valve for tubeless tires having a valve body and a valve base, characterized by the fact that the valve body has a plurality of tongues integral with the valve body, the tongues being arranged as a conical surface around the periphery of the valve body for engagement with the outside of a wheel rim, the conical surface being open towards the valve base, the tongues being elastic in transverse direction and rigid in longitudinal direction, and free ends of the tongues being capable of moving in transverse direction and then resuming their initial shape, thus enabling an elastic sealing ring to be tightened between the valve base and a valve hole in the wheel rim; said valve body, including its tongues, and valve base being formed of an integrally molded plastic material.",
    "2. A tire valve for tires with an inner tube having a valve body and a valve base, characterized by the fact that it comprises: (a) an element having tongues which are arranged as a conical surface around the periphery of the valve body for indirect engagement with the inner tube and which are elastic in transverse direction and rigid in longitudinal direction and free ends of which are capable of moving in transverse direction and then resuming their initial shape, and (b) a rigid washer beneath the element for engagement with the inner tube, the rigid washer having an outer circular joggle whose height is substantially equal to the length of the tongues; said valve body, valve base and element being formed of an integrally molded plastic material.",
    "3. A tire valve for tires with an inner tube having a valve body and a valve base, characterized by the fact that it comprises (a) an element having tongues which are arranged as a conical surface around the periphery of the valve body for indirect engagement with the inner tube and which are elastic in transverse direction and rigid in longitudinal direction and free ends of which are capable of moving in transverse direction and then resuming their initial shape, and (b) a rigid washer beneath the element for engagement with the inner tube, the rigid washer having a circular groove in its outer face, the outer edge of which circular groove has a radius slightly greater than the distance between the free ends of the tongues and the axis of the valve; said valve body, valve base and element being formed of an integrally molded plastic material."

  "description_excerpt": "This is a continuation of application Ser. No. 101,632 filed Dec. 10, 1979, now abandoned, which is a continuation of application Ser. No. 891,467, Mar. 29, 1978, now abandoned.\n\nThis invention relates to tire valves and more particularly to the manner for the airtight fastening and clamping thereof on their support.\n\nIt is known that tires are used with or without an inner tube; in the former case, the valves are fastened to the inner tube and then threaded into a hole which passes through the rim so as to make them accessible from the outside; in the latter case, the valves are fastened directly to the rim, through which they pass in airtight manner.\n\nThe embodiments existing up to the present time have the following drawbacks: the valves for inner tubes are vulcanized together with the inner tubes which complicates manufacture; valves for mounting without an inner tube are fastened to the rim either by the clamping of a nut, which is expensive, or by the deforming of a rubber bulb within the hole in the rim, which is not very reliable.\n\nThe object of the present invention is a valve which overcomes these drawbacks while permitting economical manufacture and simple and rapid use, whatever the support (inner tube or rim).",
