Abstract

The pneumatic time delay comprises a variable vol. chamber, held at max. vol. by a spring etc., and with a passage allowing air flow at a controlled rate between the inside and the outside. This passage is formed by a groove in a first surface and running for part of a circle, one end of the groove being closed and the other connected to a first port. A second complementary surface bears against the first one to form a seal between the, and has a second port leading to the air flow passage. The two surfaces are movable in relation to each other in the angular direction, one port being connected to the inside of the chamber and the other to the outside.
