Automatic opening, dosing and closing valve

Abstract: It consists of a cylindric valve body (2), with a cen­ tral outer area and two threaded ends. Inside, the body (1) has an annular seat for the cylindric closing valve (2) pro­ vided with an Or-ring seal (3) for this purpose. The valve (2) is mounted on a bottom guide (7) which closes the body (1) at the bottom and upon which the bottom end of a spring (4) rests with insertion of a self-adjustable ring (5) and an Or-ring seal (6.)

Description: The instant invention relates to an automatic opening, dosing and closing valve for use in connection with fluid pipe outlets and conceived to replace conventional cocks, taps and/or flow valves. The valve is connected with its one end to a fluid supply and with the other to a coupler or connector of a fluid receiving line and automatically opens when the coupler is connected to the valve, closes when the connector is removed from the valve and also, when the coupler or connector is threaded to the valve, the valve doses the passing fluid according to the degree of threading of the coupler or connector to the valve body. The invention as defined in claim 1 provides a greater safety, requires less space than conventional valves and is simple in structure and unexpensive to manufacture. One way of carrying out the invention is described in detail herebelow with reference to the drawings which illustrate only one specific embodiment, in which: Fig. 1 is a raised view of the valve assembly with half a longitudinal section showing the arrangement of the valve's inside assembly. Fig. 2 - It represents a top plan view. Fig. 3 - It represents a bottom plan view. DESCRIPTION OF THE PREFERRED EMBODIMENT The following elements have been indicated in these figures with the references given hereinafter: 1 - Valve body 2 - Closing valve 3 - O-ring seal 4 - Compressing spring 5 - Self-adjustable ring 6 - O-ring seal 7 - Bottom guide 8 - Top opening passages 9 - Bottom opening passages Referring to the above cited illustrations which have a schematic form of the industrial embodiment thereof and which are only included with a merely informative nature and therefore non-restrictive one, we will have: An automatic opening, dosing and closing valve, formed by a valve body (1) which houses inside it the closing valve (2), upon the O-ring seal (3). Said valve (2) is mounted on the bottom guide (7) and pressed in opening and closing by the spring (4), the self-adjustable ring (5) and the O-ring seal (6.) The flow of the fluid is done through a series of top opening passages (8) over the top part of the valve body (1) and another series of bottom opening passages (9) over the bottom guide (7.)

Claims: Automatic opening, dosing and closing valve consisting of: a cylindrical valve body (1) having on its outer surface a central hexagonal area and outer end threads for connecting said valve body (1) on one end with a fluid supply and on the other end with a coupler or connector; a bottom member (7) shiftingly provided in the cylindrical inside of said valve body (1) on said other end of the valve body (1) and having a series of bottom holes (9); a valve member (2) mounted with one end on said bottom member (7) and cooperating with its other end via an O-ring seal (3) with a valve seat provided in the inside of said valve body (1) between said bottom member (7) and said other end, said other end of said valve member (2) being configured such that a series of holes (8) is formed between said valve member (2) and the inside of said valve body (1); a compressing spring (4) arranged between said valve seat and said bottom member (7); whereby in the case where said connector or coupler is connected to said valve body (1), said bottom member (7) is shifted against the force of said spring (4) in a direction to open said valve member (2) and in the case where said coupler or connector is removed from the said valve body (1), said spring (4) automatically closes said valve member (2) by shifting said bottom member (7) in the opposite direction. Valve according to claim 1, wherein said O-ring seal (3) is mounted on said valve member (2) whereby said valve seat provides sealing with said valve member (2) and said O-ring seal (3). Valve according to claim 1, wherein a further O-ring seal (6) is situated on the upper end of said bottom member (7) which abuts against a self-adjustable ring (5) abutting against the lower end of said spring (4).
