Abstract
A pneumatic timer has a bellows with a space inside it joined up with the outside atmosphere by way of an adjustable choke. For starting a timing operation, the bellows is compressed by a pneumatic actuator which is then automatically moved back so that the bellows' speed of motion back into its starting position is controlled by the choke adjustment. The end position of stretching of the bellows is sensed by a sensing unit. This sensing unit may furthermore be moved for adjustment in the axial direction of the bellows.
