The invention relates to a valve system for filling and aerating seat upholstery, especially in the seats of vehicles, comprising at least one fluid pressure source which can be connected to a seat upholstery input by means of an inlet valve (24), also comprising an aeration valve which is connected on one side to a seat upholstery output and on the other side to a fluid pressure sink. In order to better adapt the valve system to the requirements of the dynamics of vehicle movement such that at least the inlet valve (24) is provided with a flow channel (49) which is formed by the valve body and valve seat (36) and which has a modifiable cross-section at least in one specific movement section when a relative movement is performed between one part (34) of the valve body and the valve seat (36). The invention also relates to an advantageous control device, especially for said valve system. |
