Immersion type water trap

The invention relates to a bag-type water trap with a cup-shaped lower part and a detachable, funnel-shaped insert 5, the outer circumference of which is smaller in the lower part than the inner circumference of the cup-shaped lower part and which is formed so as to be placed in the cup-shaped lower part from above and ending at a distance from the bottom by means of intermediate ribs which keep the upper-10 end of the insert at a certain distance from the upper end of the cup-shaped lower part when forming the outlet openings between the two parts.

It has been found that so much dirt particles can rapidly accumulate in the intermediate ribs that said outlets become blocked, which is not desirable. It is therefore an object of the invention to provide a method for eliminating this drawback.

According to the invention, this is achieved in such a way that at least at the height of the intermediate ribs between the funnel-shaped insert and the cup-shaped lower part, partitions are placed which separate the annular space formed between the insert and the lower part as separate flow-through parts.

Thanks to these partitions, for the water to be removed: a flow rate is obtained which avoids the undesired accumulation of dirt particles in the area around the spacers.

According to the invention, a very advantageous water trap structure is obtained in such a way that the volume of said annular space delimited by one part of the funnel-shaped insert is made ... smaller than the volume of the 30 parts delimited by the same part of the interior of the insert and that the partitions extend at least a considerable part of the length of the lower end of the insert.

Due to this special form of volume conditions, the water pressure increases in the water leaving the lock. When used with the partition structure 35 characteristic of the invention, the water trap is made to remain very clean of 2,88950 dirt particles. In a conventional water trap without partitions, dirt particle accumulations around the spacers, which interfere with the operation of the water trap, also occur as the water pressure increases.

An embodiment of a water trap according to the invention will be described in more detail below with reference to the drawing, in which Figure 1 shows diagrammatically a longitudinal section of a water trap, and

Fig. 2 is a cross-sectional view taken along line II-II of Fig. 1

along.

The bag-type water trap shown in the drawing comprises a cup-shaped lower part 10 and a funnel-shaped insert 12 detachably inserted into the lower part 10 from the top 15 to 15. The insert 12 has a substantially frustoconical upper portion 14 and a cylindrical lower portion 16.

In the lower part of the lower part 10 there is a cup-shaped part 18 and in the upper part there is an annular part 20, which is connected to the part 18 by intermediate ribs 22, so that between the parts 18 and 20 20 there are outlets marked by arrow 24.

The insert 12 located in the lower part rests on its upper part by means of a shoulder (not described in more detail) on the corresponding counter-shoulder of the annular part 20 of the lower part 10. The lower portion 16 of the insert 25 terminates as shown at a certain distance from the bottom 26 of the lower portion 10. The portion 16 forms an annular flow space 28 with the lower portion 10 so that water flowing from the top through the insert can again exit the water lock 28 and the outlets 24 through.

In the structure shown, partitions 30 are arranged on the outer surface of the insert 12, which are at the same height as the spacer ribs 22 and extend completely down over the lower part 16 of the insert 12 in the structure shown. With these partitions 35, the annular space 28 is divided into separate flow-through sections 3 88950 28a, as best seen in Figure 2. This provides a flow function that can eliminate the accumulation of dirt particles from behind in the area around the intermediate ribs 22.

The volume of the annular space 28 is smaller than the volume of the part 16 of the insert 12, so that the water pressure in the annular space increases. This can be fully utilized to enhance the cleanliness of the outlets 24.
