ABSTRACT:
A hydrostatic pressure release for releasing a life raft or the like when a ship sinks has a flexible diaphragm sealing a chamber on one side and exposed externally on its opposite side. A ceramic vent plug is mounted on the diaphragm so that it is protected within the casing of the device. The diaphragm has a resilient plate with an integral sleeve that projects through a collar in a rigid disc mounted on the plate. The plug is retained within the sleeve, in the collar. A rod projecting from the diaphragm extends into one end of an aperture in a slider and locks it in position. When the device is submerged, the diaphragm is deflected and pulls the rod out of the aperture allowing the slider to be released. A button on the slider extends into the other end of the aperture so that when is is depressed it pushes the rod out of the aperture and releases the slider.
