Abstract
A valve for wheels for pneumatic tubeless bicycle tires. The wheel has a wellbase or drop-center rim and a valve opening in the base of the wellbase for such a valve. For simple installation of the valve, the valve body is provided on the outlet end with a cylindrical projection, the outer dimensions of which correspond to the inner dimensions of a valve opening recess, so that in the installed state the valve body has a surface which is flush with the base of the wellbase of the rim.

A valve for a wheel for a tubeless bicycle tire having mounted beads, said wheel having a wellbase including a base of a narrow bicycle rim which is provided with a valve opening for receiving said valve sealingly therein regardless of overall dimensional limitations thereof;
- said vlave comprising:
- a valve body having two end portions, with the axially outer one of said end portions being provided with a cylindrical projection having an outer dimension;
- the base of said wellbase of said rim of said wheel being provided with a valve opening recess having an inner dimension, and the outer dimension of said cylindrical projection corresponds to the inner dimension of said valve opening recess in such a way that in the installed state of said valve, the axially outer end portion of said valve body is flush with the base of said well base of said rim so that said valve body is kept out of the way of the tubeless tire beads in the mounting position thereof on the narrow bicycle rim.
In combination with a bicycle wheel for a pneumatic tubeless tire having mounting beads, which wheel has a wellbase including a base of a narrow bicycle rim which is provided with a valve opening in the base of the wellbase, a valve which comprises:
- a valve body having two end portions, with the axially outer one of said end portions being provided with a cylinderal projection having an outer dimension;
- the base of said wellbase of said rim of said wheel being provided with a valve opening recess having an inner dimension and the outer dimension of said cylindrical projection corresponds to the inner dimension of said valve opening recess in such a way that in the installed state of said valve, the axially outer end portion of said valve body is flush with the base of said wellbase of said rim so that said valve body is kept out of the way of the tubeless tire beads in the mounting position thereof on the narrow bicycle rim.
