Abstract
The bird scarer includes an explosion chamber connected to a gas cylinder via an intermediate chamber of variable volume. The intermediate chamber has one wall formed by a flexible elastic membrane which controls the operation of a gas valve. As the membrane moves under the effect of the gas pressure, it also lifts a hammer which falls on to a piezoelectric lighter. The electrodes of the lighter are located in the explosion chamber. The membrane is mounted vertically on the outside of the appts. making replacement straight forward.
