Air filling valve device for use in a hydropneumatic vehicle suspension, which is exposed to a change in temperature, comprising a combination of an air filling body which is provided with a tapering valve seat and a valve core which in turn is provided with a bush seal, composed of elastomer material, which is used in the tapering valve seat, a plastic being used as material for the air filling body, which plastic has an elongation of more than 3% over a length of approximately 5 cm, a tensile strength of more than 14 kp/mm<2>, a Rockwell hardness of more than R110, a modulus of elasticity of more than 280 kp/mm<2> and a linear coefficient of thermal expansion of more than 1.13 x 10<-5> in./in. DEG F so that any air leakage between the bush seal and the tapering valve seat is eliminated. <IMAGE>
