    • The invention relates to a method of controlling the pressure in a compression chamber (10), particularly in a pneumatic braking device for a recording medium (12) in the form of a strip, in which method the actual pressure (Ip) in the compression chamber is set in relation to the actual angle (Iw) of rotation of a turning valve (14). The actual angle (Iw) of rotation of the turning valve (14) and the actual pressure (Ip) in the compression chamber (10) are recorded. An ideal pressure (Sp) and an ideal angle (Sw) of rotation associated with this ideal pressure (Sp) are predetermined and pressure deviation (Dp) between the actual pressure (Ip) and the ideal pressure (Sp) and also a deviation (Dp) of the angle of rotation between the actual angle (Iw) of rotation and the ideal angle (Sw) are fixed. Setting means (40) adjusts the angle of rotation on the turning valve (14) firstly in relation to the deviation (Dw) of the angle of rotation and subsequently in relation to the pressure deviation (Dp). The invention also relates to a sensor (22, 22', 22") for measuring the angle of rotation.
    • 的方法(IW)是用于控制压力室(10)中的压力在气动制动装置所描述的,特别是用于在其中根据的旋转的实际角度在压力室中的实际压力(IP)的片状记录介质(12) 旋转阀(14)被调整。 旋转的旋转阀(14),并在压力室(10)中的实际压力(IP)的(IW)的实际角进行检测。 期望的压力(SP)和该期望的压力(SP)相关联的目标旋转角(SW)是预先确定的和实际压力(IP)和所期望的压力(SP)和旋转偏差之间的压力差(DP)(压差 )(实际转弯角IW)和旋转(SW)的期望的角度之间被确定。 致动装置(40)表示旋转中的旋转阀(14)第一取决于旋转角偏差(DW),然后根据压力差(DP)一个角度。 此外,一个传感器(22,22”,22“)被用于检测所述旋转角说明。
