ABSTRACT:
This invention describes a pneumatic timing valve, in which one end of a plunger projects into a chamber in constant communication with the atmosphere and is displaced by fluid means into its operating position against a return spring force, an incoming pneumatic pressure signal initially being vented via the chamber. A shutter element situated in the chamber and controlled as regards time by another spring force and a restrictor system, neutralizes the venting of the pressure signal after expiration of a preset delay period, to generate a control signal. The restrictor system is separately in communication with the atmosphere and comprises a restrictor path adjustable in its effective length. In order that shorter time-lags may be set precisely within a comparatively large delay range, the invention provides that the operating position of the plunger is adjustable.
