Abstract

Improvements introduced in the object of the main patent no. 425,800, filed on april 30, 1974, by: "perfections introduced in coaxial valves" according to which a double coaxial valve sensitive to the fluid pressure that develops as a consequence of the flow of fluid in one direction or another through a fluid conduit for directing the flow in the same direction in another fluid conduit, comprises, in combination, a tubular valve housing; first and second valves in the housing, each having first and second coaxial valve members separately movable alternately within the valve housing to and from first and second valve seats, respectively, between closed and open positions, to close and open first and second flow steps, respectively; controlling one of the first and second valve elements of each valve to flow to, or from, a flow passage, and controlling the other valve elements of each valve to flow to, or from, the other flow passage; load means pushing the valve elements in one direction; and a fluid pressure receiving surface connected for operation to each valve element, which urges the first valve element in a first direction towards, or from, its valve seat, and the second valve element in a second direction, towards, or from, its valve seat, the loading force of the loading means being adjusted to oppose the movement of each valve element in said direction from, or toward, its valve seat under the differential fluid pressure that it develops as a consequence of the flow in one direction and applied to the receiving surface of the fluid pressure and to the valve element moving in that direction towards, or from, its valve seat and opening when the flow starts from that sense; one of the valve elements of the first valve and one of the valve elements of the second valve being sensitive to the fluid pressure that develops as a result of the flow in one direction from one side of the valve, and the other being the valve elements of the first valve and the other of the valve elements of the second valve sensitive to the fluid pressure that develops as a result of the flow in another direction from the other side of the valve, so that the valve is arranged to open or close in response to the fluid pressure that develops as a result of the flow and applied from one or the other direction of the flow, and to direct the flow entering the valve from said first fluid conduit from one or the other direction to one of the first and second flow passages, and to direct the flow leaving the valve through the other of the flow passages to said first fluid conduit for flow in one direction or the other, while advancing in the same direction through the fluid conduits in fluid flow connection with the first and second flow passages.
