    1. Flow meter with rotor, comprising a housing having a chamber (2) of substantially circular cross-section, into which an inlet opening (5) leads substantially tangentially and which also an outlet opening leaves, comprising also a rotor having blades which revolves in the aforementioned chamber (2) about the axis of the chamber under the action of the fluid flowing through the chamber (2) from the inlet opening (5) to the outlet opening, and comprising means for measuring the rotational speed of the rotor, the wall (3) of the aforementioned chamber (2) being furnished, adjacent to the ends of the rotor blades, with recesses (6), which extend substantially parallel to the axis of the chamber (2) and create turbulence in the fluid flowing through the chamber (2), characterized in that the said inlet opening (5) leads into one of the lateral walls (9) of one of the aforementioned recesses (6) of the chamber (2) in such a manner that at least a part of the flow strikes against the opposite lateral wall (10) of the aforementioned recess.

    The invention relates to mechanical engineering, in particular to dowels for fastening to slabs, hollow walls and monolithic building materials.
    The purpose of the invention is to increase the reliability of fastening.
    Fig, 1 shows a rod; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - dowel mounted in the hole of the part to be joined and the plate; in fig. 5 - the same, when fastening the attached part to the monolithic building material,
    The dowel for fastening to slabs, hollow walls and monolithic building materials contains a rod 1 and a screw 2. The rod 1 is made with a longitudinal hole 3 with internal thread or internal ribs 4 and two elbows extending from it 5. The knee is connected with a flange 7, located at a right angle to the axis of the rod, the fixation device from the pro-root in the form of ribs 8 and a longitudinal hole 9. On the surfaces of the knees facing each other at least half their length are longitudinal grooves 10 that are extended 9. Knee eat openings in the area between the grooves end and the head portion separated by a gap 11, and grooves between the end and the rod - gap D, the width of which is less than the diameter of the screw 2.
     the cross-section of the knees in the zone of the beginning of the gap 12 has the shape of an ellipse 13, passing to the rod 1 in a circle. At the same time, the small diameter of the ellil sa approximately corresponds to the diameter of the drilled hole in the parts. At the end of the grooves 10 and the beginning of the gap 12 in the plane of the gap, the field hole 14, forming thinning, is made. In the zone of connection of the knees with the rod, cut-outs 15 are made at right angles to the plane of the gap. The gap 12 is V-shaped with the top facing the rod. Such an implementation of the gap 12 is most appropriate.
    When fastening the attached joint 16 to the plate 17, the rod 1 reaches the rear side of the plate by screwing the screw 2 into the longitudinal hole 3 of the rod 1. In this case, 25

    : | 5 radially bent by the action of the longitudinal load at the site of the longitudinal bending and compressed axially. On the right side of the slab, an additional support of a large area arises, which provides a secure, fastening in soft and porous slabs, for example, in gypsum plasterboards.
    Through longitudinal grooves made on the length of the knees ,; approximately half the length, the screw passes unhindered before the start of the gap 12. The width of the gap, smaller than the screw diameter, causes the knees to bend under the action of a longitudinal load when the screw is screwed into the gap, which reduces the bending forces during the final deformation of the knees. When the rod 1 is driven into the drilled hole 18, made in monolithic building material 19 and corresponding to the diameter of the rod 1 and the head part 6, both elbows 5 are compressed due to the narrowing of the gap 12. When the screw 2 is screwed into the narrowed part, the dowel in the drilled hole occurs. , - I
    Since for fixing the dowel in slabs and hollow walls it is not necessary to form a protrusion by twisting the sides, and only bending under the action of a longitudinal load is necessary, the dowel can be made of high-strength synthetic material, which prevents scrolling of the bit when installing the plates and reliably The plug in the dowel in 4Onolit5O 1x construction materials is being removed.
