    The invention relates to respiratory protection, to a light-controlled membrane valve for respirators with a device for obtaining excessive pressure in the internal cavity of a respirator.
    The aim of the invention is to create an overpressure in the internal cavity of the respirator during the entire 30th cycle of respiration.
    1 shows a diaphragm valve, side view, partial section; in FIG. 2 a double-arm lever, top view.
    The diaphragm valve consists of a body 1, divided by a membrane 2 into an external chamber 3 connected to the atmosphere, and an internal chamber 4, which conducts the respiratory gas. Chamber 4 has a connecting nipple 5, to which a respirator can be attached (not specified) “Chamber 4 is connected to the inlet valve 6, to which the connecting nipple 7 for fresh gas is connected. Departing 45 from the intake valve 6, the lever 8 is located in the chamber 4 and touches the membrane 2 in the center. Membrane 2 in its. The center has a pin 9 in the form of a pin, which has a thickening 11 at its end facing the wall 10 of the outer chamber 3. Two helical springs 12 are stretched across the outer chamber 3, the ends of which are fixed to the fixing parts 13 of the outer chamber 3 and on the second shoulder 14 of the double-shouldered lever 15 "A yoke 16, placed in the outer chamber 3, holds the swinging double-arm lever 15 on its hinges 17, the latter are located at close spatial distance from the second shoulder
    14, swing arm
    15. A shell 18 is fixed around the housing of the outer chamber 3, having a bulge in the form of a button 19, which is an element for disabling the working position of the two shoulders 15, and the button 19 enters, squeezing inwards, into an opening made in the wall 10 of the outer chamber 3.
    The end of the first shoulder of the swinging two shoulders lever 15, interacting with the membrane 2, is made in the form of a fork 20, covering the lead 9, the width of which is greater than the distance between the helical springs 12 "
    The double-shouldered lever I5 is installed in the hinge 17 to move from a dead center position to the off position, raising the membrane 2 above the lever 8 of the inlet valve 6 ”The lead 9 is installed with a gap a relative to the wall 10 of the outer chamber 3. The gap a is smaller than the distance b from the point fit the two shoulders of the lever 15 to the plane of the membrane 2 to the middle line of the helical springs 12 "
    Diaphragm valve (figure 1) is presented in a state in which the intake valve 6 is closed and the membrane 2 is adjacent to the lever 8 of the intake valve 6.
    The swinging double-shouldered lever 15 is attached with a fork 20 of the first shoulder under

    the pressure of the spring 12 to the membrane 2 so that the thickening 11 is held from the wall 10 of the outer chamber at a distance of a. The dead position of the swinging two shoulders lever 15 is determined by the plane in which the middle lines of the coil springs 12 and the hinge 17 lie. By pressing down the button 19 to the second shoulder 14, the first shoulder with the fork 20 moves along the leash 9 to the thickening 11 and drags it during the gap and to wall 10 of the outer chamber
    3
    In this position, the swing double-sided lever 15 is in its stable, disconnected position, in which the membrane 2 is removed from the lever 8 of the valve at the same distance a.
    When passing through the dead point of the 20 two-armed levers 15, the coil springs 12 should move apart by a small amount, so that they act simultaneously as a clamp,

    Claim
    1. A lung-controlled diaphragm valve for respirators, comprising a housing, a membrane dividing the 30 housing into the outer and inner chambers, a device for creating overpressure in the inner cavity of the mask, made in the form of an external ^ 5 hinged to the housing
    two-shoulder swing arm, one arm of which is movably connected to the membrane through a lead protruding into the outer chamber, the two shoulders lever connected to the housing with the ability to move in a hinge from a dead center to an off position, raising the membrane above the inlet valve lever of the inner chamber, by
    located on both sides of the two arms of the helical springs, the leash is installed with a gap relative to the body of the external chamber, equipped with. element off the working position of the two shoulders arm, interacting with him, characterized in that, in order to create excess pressure in the internal cavity of the respirator during the entire cycle of breathing, interacting with the membrane, the shoulder of the two shoulders lever is movable along the leash that has on the end facing to the housing of the outer chamber, a thickening adjacent to the position of disconnection of the two shoulders of the lever to the inner wall of the housing of the outer chamber, and the size of the gap between the leash and the housing of the outer shell EASURES smaller distances from the abutment point of a two-armed lever to the plane of the membrane to the middle line of helical springs,
    [2]
    2, Valve pop. 1, characterized in that the coil springs in the dead-point position of the two shoulders lever lie in the same plane with it, and the end of the shoulder of the two shoulders lever interacting with the membrane is designed as a fork, covering a leash that is wider than the distance between the helical springs.
    [3]
    3. Valve pop. 1, characterized in that the body of the external chamber of the valve is provided with its enveloping shell, and the element for switching off the working position of the two shoulders lever is formed by a resiliently deformable thickening in the form of a button interacting with the second shoulder of the two shoulders lever, and a hole for the button to the second shoulder "
