Abstract
A mechanical release of an object occurs after a release device is subjec to a first pressure and then is brought to a second pressure which is less than the first. The first pressure enables or arms the device so that its actuation or release takes place when the second, specific release pressure is reached. The setting and releasing pressures are substantially less than extremely high pressures which the device is capable of withstanding. A pair of opposed biasing springs and a diaphragm with a specifically contoured solid stop prevent deformation and any sliding of sealing surfaces to avoid failure.
