Abstract
A housing has walls that enclose a pressure chamber. One of the walls is a flexible diaphragm that separates the pressure chamber from the pressure sensitive system, the diaphragm being movable to and fro between a first position and a second position in response to a predetermine change in the pressure differential between the pressure chamber and the pressure sensitive system. - At least one of the walls is a permeable wall that is permeable to fluid medium having a sufficient permeability to permit the fluid medium to pass through at a rate that will serve to permit equalisation of the pressure in the pressure chamber and the pressure sensitive system to prevent displacement of the diaphragm to the second position when the rate of change of pressure in the pressure system is less than that which is indicative of a predetermined rate of change. The permeable wall is sufficiently impermeable to prevent the passage of fluid medium through at a rate that will serve to prevent equalisation of the pressure in the pressure chamber and the pressure sensitive system at a rate that would prevent movement of the diaphragm from the first position to the second position when the predetemined rate of change occurs in the pressure sensitive system.
