Definitions

a known adjustable connection valve for the supply of respiratory air essentially consists of four elements, namely a first element, to which is connected a cap, with which the filter can cooperate in an airtight manner. a gas mask or other similar device; a second element, to which is connected an air supply pipe and which, at its free end, is closed and is provided with at least one passage, this second element being capable of being displaced relative to the first element; a third element suitable for opening or closing the valve and also having an air passage opening; and a fourth element comprising a spring tending to maintain the valve in its closed position or to bring it to this position; a special feature of the connection valve according to this main patent consisting in that the air passage openings, which must be able to cooperate mutually in an adjustable manner to ensure the supply of air or connected filter of the gas mask or another similar device extend radially in tubular elements.
the present invention relates to improvements, of the aforementioned valve, consisting mainly in that the aforesaid air passage openings are arranged axially in various mutually cooperating elements of the coupling sub-valve, which presents, inter alia, the advantage of a significant reduction in resistance by the subpape the passage of air, with, consequently, a significant reduction in the risk of formation of depression in the gas mask, as well as the advantage of a net increase in the adjustment range of the valve.
the adjustable connection valve having the above-mentioned and other characteristics consists essentially of four elements for this purpose, namely a first element, to which is connected a cap, with which it can cooperate, in an airtight manner , the filter of a gas mask or other similar device; a second element to which is connected an air supply pipe and which, at its free end is closed and is provided with at least one passage, this second element being capable of being displaced relative to the first element; a third element suitable for opening or closing the valve and also having an air passage opening; and a fourth element comprising a spring tending to maintain the valve in its closed position or to bring it to this position; characterized in that a fifth element is provided between the first and the second element, having at least one air passage opening, capable of being displaced relative to an air passage opening of the first element, in that which the second element and the third element element together form a whole and in that the passage of air through the valve is an almost completely axial passage.
the adjustable connection valve 1, illustrated by the appended figures, essentially consists of five elements, of which the first element 2, on which the cap 3 is mounted in an airtight manner, consists of two concentric parts 4 and 5 , joined, at one of their ends, by a wall 6, provided with two diametrically opposite passage openings 7.
This element 2 is, in the present embodiment of the invention, extended by a fifth element 8, consisting essentially of a cylindrical part 9, the outside diameter of which is equal to that of element 2, and of part 10, concentric with this part 9 and sliding in part 5 of element 2.
These two parts 9 and 10 are mutually connected by a wall 11 provided with two diametrically opposite passage openings 12, each having a narrow part 13 and a wider part 14.
the two elements 2 and 8 can be angularly offset one relative to the other and are, preferably rence, provided with a snap-in system intended to lock them reciprocally in determined positions.
the wall 11 is, for example, provided with notches 15, with which a ball 16 cooperates urged by a spring 17.
the second element 18 of the connection valve 1 is in the form of a wall 19, capable of sliding in the above element 8 and mounted on a tubular part 20, to which can be fixed, on one side of the wall 19 , suitably, an air hose 21, while, on the other side of the wall 19, there are openings 22 in the tubular part 20.
the end of the latter, located beyond the openings 22, is provided with an end wall 23, on which is fixed the wall 24 of the third element 25, which is appropriately fixed, for example by gluing, to the second element 18 and is thus capable of moving with this element 18 relative to the first element 2, the above-mentioned wall 24 being provided with openings 26.
the fourth element is provided, in the form of a spring 26.
the valve is closed in the position shown in FIG. 1.
the wall 19 of the element 18 applies to the wall 11 of the element 8 so as to close the openings 12, while the part of the element 18, provided with the openings 22, applies to the part 10 of the element 8, so as to also avoid the passage of air through these openings.
the third element 25 and, consequently, also the second element 18 move relative to the second element 18 and to the fifth element 8, respectively, so as to disengage the openings 22 from the part 10 of the element 8 and to move the wall 19 of the element 18 away from the openings 12, all of this so as to allow the free passage of air, brought by the flexible 21, by the tubular part 20 and the openings 22, 12, 7 and 26 towards the filter 28.
the spring 27 thus compressed ensures, when the filter 28 is removed from the cap 3, the automatic reclosing of the valve 1.
the element 8 With a view to adjusting the air flow rate passing through the filter 28 of the gas mask 29, the element 8 can be rotated relative to the element 2, so that the passage openings 7 more or less cover the openings of passage 12 of wall 11.
the free passage section can vary between a minimum value, determined by stops 30-31 (fig. 4 and 6), and a maximum value.
valves of the type to which the present invention relates are used to connect gas masks or other similar devices to a common air supply pipe, for example, in workshops giving off harmful products (gases or vapors) , in vehicles intended to cross infested areas, etc., all of this so that the persons concerned wearing a gas mask can at any time be connected to a cap 3 so as to increase the autonomy of the gas mask.
