The inventive emitter device has an elongated flow channel 2, containing a Central elongated regulating channel 3, having an essentially rectangular cross section with width (a), and two sets of consecutive running of the pockets 4 are located respectively on each side of the regulating channel 3 and facing in regulating channel. Each flow-through pocket 4 sets formed by a pair of adjacent side walls of the pair of consecutive partitions. Each wall has a side wall terminating in an edge, with partitions of the same set are directed, respectively, essentially to the midpoints of the intervals between the opposite walls of the set. Edges of partitions each set of partitions essentially aligned to form one pair of opposite longitudinal sides of the regulating channel and the other pair of longitudinal sides regulating channel 3 is formed by first and second opposite walls of the regulatory channel. Patented form for injection molding of the housing 1 exhaust is forming pockets and walls of the flow channel of the housing 1. 25 C.p. f-crystals, 13 ill.

The present invention relates to liquid water diversion and casting forms for their manufacture.

Know-outlet Pat. USA N 4060200, CL In 05 In 15/00, 1987, having a flow channel special shapes and relative sizes lying within the specified range. However, this discharge device is not effective from the point of view of reducing the pressure of the water flow at a given length of channel flow and the minimum flow gap. In addition, this discharge device is relatively sensitive to changes in inlet pressure and is prone to contamination by extraneous particles.

A known form for molding the housing outlet L. I. Winberg, "injection Molding ", M the motor cycle", 1962, S. 187-188, having a molding cavity and the insert. However, this form does not ensure high quality and accuracy of the housing outlet.

In a variant, S="ptx2">

In a variant of the invention shown in Fig.5 of the drawings, the bottom wall 10, the regulatory path 4 is slightly lowered with respect to the bottom walls of the flow-through pockets 5.

In Fig.1-5 of the drawings, a flow channel 2 has a slightly curved shape, while the concept of alignment surfaces of the edges of the walls along the longitudinal edges of the regulating path 4 includes alignment on a smooth curve, as well as in a straight line.

Practical implementation of the housing 1 outlet smoothly curved (in this case circular) flow-through channel 2 shown in Fig.6 of the drawings, where the circular flow channel 2 has a Central circular regulating tract 4, limited on each side of the respective sets of flow pockets 5 formed between adjacent side surfaces of consecutive pairs of partitions 8, where the surface edges of the partitions respectively aligned with the circular edges of regulatory tract 4.

Dimensional constraints on the relationship between the width and regulatory tract 4 the width of the extreme surfaces of the partition walls 8 and the minimum passing gap in the flow channel 2 are the same as described above with reference to Fig.3 of the drawings.

As you can see, the cavity 19 is the inverse of the shape of the teeth of the partitions 8, opening into the Central through channel 16 and, thus, moving the bounding box is used to limit and absolute alignment of the edges of the partitions. As can be seen in Fig.7 and 8 of the drawings, the upper end of the restrictive insert 17 is essentially flush with the opposite forms 18 pockets 5, and therefore the bottom wall of the regulatory path 4 will be essentially flush with the bottom walls of the flow grooves, as shown and described with reference to Fig.1 and 2 of the drawings.

In the mold shown in Fig. 9 and 10 of the drawings, the upper end of the insert 17 is shifted down relative to the surfaces opposite forms of flow grooves, and as a result, the discharge device will be performed with the regulatory path 4, the surface of which is raised relative to the corresponding surfaces of the bases flowing grooves, as shown in Fig.4 of the drawings.

In the variant shown in Fig.11 and 12 of the drawings, the upper end of the insert 17 is raised relative to the respective surfaces opposite forms of flow grooves, and as a result, produce down toward the respective bottom walls of the flow-through pockets.

In the variant shown in Fig.13 of the drawings, a round mold 20 has a body in which you have Central circular channel 21, is essentially rectangular in cross-section, which may be adjustably mounted tubular bounding box 22 corresponding rectangular shape in cross section. This mold is designed for the manufacture of the exhaust device shown in Fig.6 of the drawings.

In the variants shown in Fig.9-13 of the drawings, the mold has a Central through-channel, which holds the movable bounding box, which allows not only the exact location and the desired distance between the edges of the partitions, but also allows you to change the depth b of the regulating channel. Molds corresponding to the invention, can be performed with a restrictive element, which is fixed relative to the body shape and which serves only to ensure accurate location and required distances between the edges of the partitions.
