Electronic unit for measuring operating parameters of a vehicle wheel, comprising an electronic casing and an inflation valve of elastically deformable type

An electronic unit for measuring operating parameters of a vehicle wheel, comprising:

• an inflation valve of the elastic deformation type, comprising:
• a valve body made of an elastomer material, provided with a longitudinal axial bore and intended to extend through an orifice made in a rim of the wheel, said valve body being made up of an elastically deformable trunk and of an abutment head for butting against the rim, which head is separated from the trunk by a neck designed to become positioned in airtight fashion in the orifice made in said rim, and
• a rigid hollow tube extending into the valve body,
• said valve body and said rigid hollow tube being designed and assembled so as to allow an elastic deformation of the trunk of the valve body in order to allow installation of the inflation valve through the orifice of the rim,
• an electronics casing, and
• means of attachment of the electronics casing and of the inflation valve, in a position of said electronics casing in which the latter extends in the continuation of said inflation valve,
• wherein the means of attachment of the electronics casing and of the inflation valve consist of a solid pin made from a material having a density lower than that of the material of which the rigid hollow tube extending into the valve body is made and having, at least over a portion of its length, longitudinal grooves that allow a flow of air to pass through said inflation valve, a proximal portion of said pin being configured to be attached to the electronics casing, and a distal portion of said pin being configured to be attached to the rigid hollow tube of the inflation valve.
