Tire valves for tubeless and tube tires

Claim 2

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.

Claim 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 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.

Claim 4

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.

Claim 5

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.

Claim 6

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.
