Abstract
A valve unit (1) with a single-piece valve body (4) includes a cylindrical collar (5), a valve seat (7), a main duct (9) and an auxiliary duct (10). The cylindrical collar (5) projects from a reference plane (12) obtained in the valve body (4) and is configured so that it can be arranged against a rim (2) when the cylindrical collar (5) is inserted in a hole (6). The cylindrical collar (5) has an end (5a) configured so that it can be deformed and can define a flared portion (13) of the main duct (9) which interferes with the rim (2) at the level of the hole (6) thus providing a mechanism (11) for fixing the valve unit (1) to the rim (2).
Claims12
A valve unit for wheels having a rim with at least one tyre, the valve unit comprising a valve body comprising:
- a cylindrical collar suited to be inserted in a hole made in said rim;
- a valve seat accommodating an auxiliary valve for inflating said at least one tyre;
- a main duct passing through the length of said cylindrical collar;
- an auxiliary duct that intersects said main duct in order to place said valve seat in communication with said main duct,
- wherein said valve body is a single-piece body in which said cylindrical collar, said valve seat and said main duct and auxiliary duct are obtained, said cylindrical collar projecting from a reference plane obtained in said valve body, said reference plane being configured to be arranged against said rim when said cylindrical collar is inserted in said hole, an end of said cylindrical collar being configured to be deformed for defining a flared portion of said main duct, said flared portion being configured to interfere with said rim at the level of said hole thus obtaining means for fixing said valve unit to said rim.
