    The invention relates to a breathing mask with a mouth and nose covering mask body, which forms an air inlet and provided with a check valve air outlet.
    In order to train the breathing and the respiratory muscles, the inhalation resistance can be increased. For this purpose, respiratory masks are used which have an air inlet with a correspondingly reduced flow cross section and a separate from the air inlet, equipped with a check valve air outlet, which is provided for unobstructed exhalation with a comparatively large flow cross-section. So that the inhalation resistance can be adapted to different requirements, it is known (US 2012/0094806 A1) to close the air inlet with interchangeable screw caps, which have a different number of air inlet openings or different sized air inlet openings, so that with the selection of appropriate screw the flow cross section of Air intake can be adapted to different requirements. The disadvantage, however, is the spatially separated arrangement of the Luftein- and outlet conditional, relatively complex construction and the need to use different screw caps for a required adjustment of the air inlet.
    The invention is therefore based on the object, a respiratory mask in such a way that with simple constructive means of inhalation resistance can be adapted to different requirements.
    Starting from a breathing mask of the type described above, the invention achieves the stated object in that the air inlet comprises a receptacle for a rotary valve with at least one central air outlet partially enclosing air inlet opening that the rotary valve covers the air inlet opening in dependence on its rotational position, and that the check valve for the air outlet has an air outlet opening covering, centrally held membrane.
    By providing a central air outlet in the receptacle for the rotary valve, which cooperates with at least one air outlet partially enclosing air inlet opening, the conditions for a simple, compact design are created, with an advantageous adjustment of the flow cross-section through the cooperating with the at least one air inlet opening rotary valve given for the air intake. The respective rotational position of the rotary valve determines the angle over which the air inlet opening is covered by the rotary valve, and thus the inhalation resistance. The central air outlet also allows the formation of the required for the air outlet check valve as structurally inexpensive diaphragm valve with a centrally held membrane covering an air outlet opening, so that the membrane is lifted during exhalation from the edge of the air outlet opening and the air outlet opening releases. The onset of inspiration suppressing supports the dense concern of the membrane at the peripheral edge of the air outlet opening.
    Particularly simple construction conditions arise in this context when the air outlet forms a guide cylinder for the rotary valve and the rotary valve forms the covered by the diaphragm air outlet opening. In this case, it requires no separate support of the diaphragm by receiving the rotary valve, because the rotary valve, which forms the covered by the membrane air outlet opening, can even take over the central support of the diaphragm. With respect to the air outlet opening central support of the membrane can indeed be formed simply by a hub carried by spokes within the air outlet opening, said spokes can be advantageously used for radial support of the diaphragm in the closed position of the check valve.
    To secure the axial position of the rotatably mounted in the guide cylinder rotary valve, the rotary valve can engage behind the guide cylinder with axial spring tongues which form a kind of snap closure, so that the rotary valve, which forms its guide in the guide cylinder recording corresponding axial Führungsansätze, with the spring tongues ahead only in the guide cylinder must be inserted until the spring tongues engage behind the inner end edge of the guide cylinder.
    In order to specify different flow cross-sections for the air inlet, the rotary valve may have a radially outwardly projecting, resilient latch which cooperates with circumferentially successive latching recesses of the receptacle. Thus, the rotary valve is locked in different rotational positions corresponding to a different flow cross-section and thus a different inhalation resistance due to the different coverage of the air inlet opening.
    If the air inlet is divided into several air inlet openings distributed around the air outlet, the setting angle for the rotary valve for setting different flow cross sections is reduced. Advantageous construction conditions arise in this context when the recording and the rotary valve each have three evenly distributed around the air outlet, each having an angular range of 60 ° extending air inlet openings, because in this case the rotary valve only 60 ° between the closed position and the full Open position must be adjusted.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a breathing mask according to the invention in the region of the air inlet and outlet in a simplified longitudinal section,
    2 shows a section along the line II-II of FIG. 1 on a larger scale,
    Fig. 3 is a representation corresponding to Fig. 2, but in a relation to FIG. 1 different rotational position of the rotary valve and Fig. 4 is a section along the line IV-IV of Fig. 2 in a larger scale.
    The respiratory mask according to the illustrated embodiment has a mask body 1 which covers the mouth and nose and is provided with a flexible sealing edge 2 for tight connection to the face shape. The mask body 1 is provided with an air inlet 3 and an air outlet 4, which cooperates with a check valve 5. The air inlet 3 is assigned to adjust the flow cross section, a rotary valve 6, which can be adjusted via a hand lever 7. The mask body 1 forms for the rotary valve 6 a receptacle 8, which comprises the central air outlet 4, which is bounded by a guide cylinder 9 for the rotary valve 6. For storage of the rotary valve 6 in the guide cylinder 9 of the rotary valve 6 is provided with radial guide lugs 10, which keep the rotary valve 6 relative to the guide cylinder 9 centered. The axial securing of the rotary valve 6 is achieved by spring tongues 11, which engage behind the guide cylinder 9 on the inner end face, as shown in particular in FIG. 4 can be removed.
    The receptacle 8 for the rotary valve 6 has three the air outlet 4 uniformly enclosing air inlet openings 12 which cooperate with corresponding air passage openings 13 of the rotary valve 6. Since the air inlet openings 12 of the air inlet 3 and the air passage openings 13 extend in the rotary valve 6 in each case over an angular range of 60 °, by a rotational adjustment of the rotary valve 6 by 60 ° released by the rotary valve 6 flow cross section between the air inlet openings 12 covering the closed position and a the air inlet openings 12 are fully open position adjusted. To determine certain rotational positions of the rotary valve 6, this may be provided with a radially outwardly projecting, resilient detent 14, which cooperates with circumferentially successive recesses 15 of the receptacle 8. 2, the closed position, in FIG. 3 shows a partially open position. In order not to completely interrupt the air supply in the closed position, an always open, additional air inlet opening 16 may be provided.
    In order to achieve simple construction conditions, the rotary valve with a cylindrical projection 17 can form a central air outlet opening 18 for the air outlet 4 and receive the check valve 5. The check valve 5 is formed by a diaphragm 19 which is held by a hub 20 carried by spokes 20 and cooperates with the front edge of the cylindrical projection 17, wherein the spokes 20 represent an additional support of the diaphragm 19 in the closed position. Upon inhalation arises on the inside of the air outlet 4, a suppression that holds the diaphragm 19 in the closed position, so that the air can be sucked and inhaled only over the released from the rotary valve 6 sections of the air inlet openings 12. When exhaling causes the pressure of the exhaled air opening the check valve 5 by the membrane 18 is lifted from the front edge of the cylindrical extension 17, so that in addition to the released portions of the air inlet openings 12 and the air outlet opening 18 is available for unobstructed exhalation.
    To protect the check valve 5, the receptacle 8 of the mask body 1 is provided with an air-permeable cover 22, which is indicated in phantom in FIG.
