    • Inside a syringe (1) slides a plunger (2) which bears a joint (4) sliding sealingly over the internal wall of the syringe. The flexible membrane (6) of the joint (4) fixed to the end of the plunger (2) bears a closing component (25, 27) which follows the movement of deformation or displacement of the membrane through the effect of the pressure built up during the injection stage, but which is retained by immobilizing strips (17) in a position in which it opens the orifice, breaking the seal between the top and the bottom of the joint, as soon as the membrane returns to its initial position.

    • The invention relates to a pressure measuring module for a tyre (10) comprising an air pressure sensor (50) with an air inlet (51), an intermediate base (40) and a valve (30). It is characterised by the fact that the pressure sensor is mounted laterally with respect to the axis of the valve. In particular, the air inlet of the sensor is turned radially towards the outside of the rim and the pressure sensor is exposed to the flow of air (81) passing through the valve (30) causing negative pressure at the air inlet (51). The invention makes it possible to avoid dirt from being deposited in the air inlet of the sensor.
    • 本发明涉及一种用于轮胎(10)的压力测量模块,包括具有空气入口(51),中间基座(40)和阀(30)的空气压力传感器(50)。 其特征在于压力传感器相对于阀的轴线横向安装。 特别地,传感器的进气口径向转向边缘的外侧,并且压力传感器暴露于通过阀(30)的空气流(81),从而在空气入口(51)处产生负压。 本发明使得可以避免灰尘沉积在传感器的进气口中。
