Abstract: A throttle device has a holding structure, to which a throttle tongue is attached with a proximal end section, which projects into a throttle channel with a distal end section ending freely and divides same into two throttle channel sections. The throttle tongue can be pivoted into various pivot positions depending on the pressure difference prevailing between the two throttle channel sections with accompanying rubber-elastic reversible deformation starting from a neutral position in order to automatically adapt a free flow cross-section to the respective need.

Abstract: A compressed air provision device (2) for aerating a first pressure chamber (10) of a pneumatic actuator in order to actuate an actuator element (11) of the pneumatic actuator (3) in accordance with an actuation specification, in particular a position, movement, pressure and/or force specification. The compressed air provision device (2) is configured to calculate an aeration period (bd) and to aerate the first pressure chamber (10) in accordance with the calculated aeration period (bd) in order to bring about actuation of the actuator element (11) in accordance with the actuation specification.
