Embodiment Construction

[0094] figure 1 An embodiment of a valve stem system 1 is shown mounted on a wheel rim 50 (in particular a tubeless wheel) comprising a mounted tire 60 . The tire 60 is filled with a sealant 70 to seal the tire. The stem system 1 protrudes towards the outer (central) surface of the rim and is fastened at the rim 50 using nuts 14 .

[0095] figure 2 An embodiment of a valve stem system 1 comprising a tubular valve stem body 2 and a first valve element 5 is shown. The valve stem body 2 has a first end 3 and a second end 4 connected by a passage extending through the valve body 2 in the longitudinal direction. A cap 15 is provided which is screwable at the first end 3 of the valve stem body 2 . The cover 15 protects the inner volume of the valve stem body 2 from contamination and may act as an additional sealing element to prevent the passage of pressurized gas through the valve stem body 2 . The first valve element 5 is arranged at the second end 4 of the valve stem body 2...

Abstract

The invention is directed to a valve stem system (1) for tubeless wheels. The valve stem system (1) comprises a valve stem body (2) with a first end (3) and a second end (4), wherein the second end (4) is located in a tire / rim-volume when mounted at the wheel. A first valve element (5) is arranged at the second end (4) of the valve stem body (2). The first valve element (5) is a self-sealing one-way valve. The invention further concerns a probe (30) for a valve stem system, a method to test the amount of sealant in a wheel and a refilling assembly (80) for the wheel.

Description

[0001] field of invention [0002] The invention relates to a valve stem system for eg a bicycle wheel, in particular for a tubeless wheel. Background technique [0003] WO 2010 / 009887 relates to a device for filling pneumatic tires, especially bicycle tyres, using tire sealing fluid through a valve of the tire. The device is configured as an adapter set with a connector for the tire fluid and with individual parts that can be plugged into each other and by plugging, clamping and / or Screwed into the valve, the individual components may vary relative to each other depending on the valve type, such as a Dunlop valve, Quick valve, or Sclaverand valve. [0004] US 2006 / 0021472 relates to a device for injecting tire sealant fluid into a tyre. A syringe type reservoir is connected to a long flexible tube which in turn is connected to a valve stem connector. The stem connector has two different threads (Schrader and Presta) to accommodate both types of valve stems. Schrader threa...
