Abstract
A pressure measuring device for a bicycle has a housing that includes a pressure chamber. The pressure chamber has a valve disposed in a first opening and a second opening into or out of a tire assembly volume of a tire assembly. A sense element is in pressure communication with the pressure chamber along a flow path between the first and second openings.
Claims19
A pressure measuring device for a bicycle, the pressure measuring device comprising:
- a housing having a housing alignment feature;
- a pressure chamber disposed in the housing;
- and
- a valve device passing through the housing and in pressure communication with the pressure chamber and with a tire assembly,
- wherein the valve device comprises a valve device alignment feature configured to interact with the housing alignment feature to fix a rotational position of the housing relative to the valve device about an alignment axis.
