1 2 The invention has set itself the task of increasing the rigidity of the wire basket, to stabilize its seat in the valve housing and to counteract it 1. To secure the check valve with a side by accidental detachment as well as its ribs guided valve disc, which together with 5 simplify position. a closing spring with a spring abutment in one. Flat housing with valve seat undersized in that the bracket arms are brought to the valve seat m, the spring abutment together with the annular groove encircling the circular arc with the guide ribs are bent at right angles from one of the preferred not, and that the free way two in the flow path Crossing io leg ends are bent back in opposite directions and existing stiff, spring in the housing a lateral housing rearward rotation in the housing and firmly latched wire basket is formed, the legs clamp in the annular groove, the leg ends of which extend transversely to the flow direction according to a further feature of the spokes as an abutment for the closing spring invention is preferably used up to the bracket arms, while the free bracket arms are returned at right angles and there spring the legs by clamping Hg in the direction of the valve seat bent into the back rotation.
Form guide ribs for the valve plate and only the bracket arms are thereby opened Immerse in an annular groove, thereby stressed, so that the wire basket indicates that the bracket arms (9) achieve a high degree of dimensional stability and distort the valve seat (2) in the annular groove (10). and legs (11) encompassing buckling loads at right angles cannot occur. It is also safer to bend, and that the free leg seat of the wire basket is bent back in the opposite direction under high stress and ensures that it is in the right direction. In addition, by reducing the number of bends to be carried out, a number of bends to be carried out, a springing and the legs (11) in the annular groove (10) as approval in the basket production is achieved by reducing the lateral rotation of the housing (13),
clamp. In the drawing is an embodiment of the 2. Check valve according to claim 1, characterized by the subject matter of the invention. It shows
characterized in that the free leg ends Fig. 1 shows a check valve in side view, partly (12) up to the bracket arms (9) led back in section AB and are and there the legs (11) clamped in 30 Fig. 2 is a plan view of this valve. compress the relief (13). A valve housing 1 with a valve seat 2 has 3. Check valve according to claim 1 and 2, a valve plate 3, which by a closing thereby characterized in that the spring 4 in the annular groove is pressed against the valve seat 2. For the (10) resting leg (11) of a bracket guiding the valve disk 3 and as a spring abutment a wire basket 5 is provided, which consists of two adjacent bracket extend. crossing single brackets 6 and 7 consists. While the transverse to the flow direction spokes 8 of the wire basket 5, the abutment for the Form closing spring 4, the bow-type object bent at right angles to 40 in the direction of the valve seat 2 are used of the invention is a non-return valve 9 as guide ribs for the valve plate 3 and til with a laterally guided valve through ribs dip into a valve seat 2 surrounding it plate, which together with a closing spring with Fe ring groove 10 a. the abutment in a flat housing with According to the invention, the bracket arms 9 are to, Valve seat is accommodated, the spring counter 45 the valve seat 2 in the annular groove 10 in the shape of a circular arc bearing bent at right angles together with the guide ribs from a comprehensive leg 11, of preferably two cross each other in the flow path The free leg ends 12 are in opposite directions, Zenden single bracket existing stiff, reaching in the housing up to the bracket arms 9, bent back firmly latching held wire basket is formed, and springs, the legs 11 in the annular groove 10 firmly Reservoirs 50 running transversely to the direction of flow, jamming into a lateral rearward rotation 13 of the housing chen serve as an abutment for the closing spring, select a. rend the free bracket arms at right angles in the direction of the legs 11 of one bracket extend Guide ribs bent towards the valve seat for up to the bracket arms 9 of the other bracket 6 form the valve disc and in an annular groove or 7, so that this makes the bracket in a simple manner chen. 55 are secured in their position to each other.
