Inflation fluid supply and discharge assembly, in particular for inflatable diving equipment, such as buoys, surface-marker buoys, balancing jackets or the like, and inflatable diving equipment provided with such assembly

Abstract

An inflation fluid supply and discharge assembly includes a combined two-way inlet and outlet valve having a valve body with two separate flow paths separated for flows in opposite directions. Each flow path is associated with a valve seat with a shutter, which cooperates with the valve seat in the manner of a non-return valve. One of the flow paths, intended for the passage of an incoming flow to a collection body, can be connected to a fluid supply source, the other flow path enabling the passage of a discharge flow from the collection body. A shutter is stably stressed against the corresponding valve seat, in a position of interdiction of the discharge or outlet flow, and is moved to a position at a distance from the valve seat by control members or automatically by a predetermined overpressure condition of the fluid in the collection body.
