The invention relates to an inflation valve intended to be installed in an orifice of a wheel rim of a vehicle. The valve is of the elastic deformation type having a valve body (30) made of an elastomer material and a hollow rigid tube (40), and is characterised by comprising a device (70) able to be fixed on the hollow rigid tube (40) and having a portion (70a) allowing a rotational movement of the valve in a first direction of rotation when the inflation valve is mounted in a hole of the wheel rim and a portion (70b) preventing the rotational movement of the valve in a second direction of rotation opposite the first direction of rotation. The device thus formed acts as a means for limiting any elastic deformation of the valve.
本发明涉及一种旨在放置在车辆的轮辋的孔中的充气阀,该阀是具有弹性变形的类型,具有由弹性体材料制成的阀体(30)和中空刚性管(40),其特征在于,其包括能够固定在中空刚性管(40)上的装置(70),并且该装置(70)具有当所述充气阀安装在轮辋的孔中时允许所述阀沿第一旋转方向旋转运动的部分(70a),和防止所述阀沿与第一旋转方向相反的第二旋转方向旋转运动的部分(70b),所得装置用作阀的弹性变形限制装置。
