Such devices generally employ a facility which causes the rotation of the part guiding the jet.

Sometimes it is desirable to point the beam in a particular one Direction to send over a longer period of time than can be achieved with a constantly moving beam. the The present invention provides such a beam which travels in any of a number of directions over a substantial Period can be directed.

According to the present invention is a fixed one Head is provided which has a plurality of openings, each of which points in a different direction from the head. Of the Fluid streams through one after the other at time intervals do different openings of the head skillfully.

The present invention is realized by that a housing is provided which is connected to a source for liquid or I * water can be connected under pressure. A piston is provided within the housing which has a cavity with an opening for the liquid below Has pressure and closed or almost at the other end is closed so that the piston due to the "irkiuig of the './asserdruckes is moved or raised, uui a pouring opening out of the hollow piston in alignment or correspondence with an opening from de.;.

assigned channel is determined. If then the MUsvSigkfii Lsdruck decreases, the piston moves back or in lines and brings the outlet opening from the respective housing opening away, interrupting the beam.

A housing part located near the piston is with Strand cam control parts with one attached to the piston Curve device attacks. When the piston is pushed by the fluid pressure and the subsequent decrease in the Pressure is moved and moved back, the piston is controlled by the cam control against the head by a certain amount Angle rotated so that the next time you press the The piston has its outlet orifice oriented towards another part of the head in order to divert the jet of liquid into another »» Direction than that of the preceding ray / u se ': i ckeu. So if the fluid pressure is switched on and off at intervals there are jets of liquid from the mouth of the cone sent paragraph by paragraph one after the other through different Uf fnim ^ iMi. The duration of the individual rays depends on the Time during which the fluid pressure is turned on.

The above-mentioned and other features of the present invention will become more clearly understood from the following detailed description and Deii \ <e i iia ί Λ ·, t s / Eicl-calculations indicate where

l'Orm of a cone 13 expanded, which has a peripheral rim lh . The upper end of the housing contains a body 15 which is flared outwards conically at 16 and thereby forms an annular flange 17 which is fastened in the Urafangskranz lh of the housing by means of suitable screws 18. From the cone 16 and the flange 17 are a number of radial webs 19 vertically upwards, on which a flat upper part is arranged. An O-ring 18a prevents liquid from leaking between the body 15 and the housing. The webs form a number of openings 21 which are arranged around the circumference of the head and extend outwards in a horizontal direction from a central zone.

The various webs 19 are all connected at their upper side to the outer surface of the circular lid 20, and their lower parts run downwards, where they meet the upper conical surface of the part 16. A collar 23 is attached to the underside of the body 15 by means of screws 2h which run through a circumferential flange 25 of the collar. This collar 23 extends downward from the body 15 and has at its lower end an inner cylindrical surface 23a which is concentric with the vertical longitudinal axis of the device and has the same inner diameter as the inner cylindrical surface 2b of the body 1υ.

Device is arranged is arranged in the cylindrical surfaces 23 a and 26 movable up and down. The upper end of the piston 27 is closed by a horizontal cover 28, which is preferably provided with a small ventilation opening 29. The lower end of the hollow piston 27 is open at 30 and is formed at its lower end with an outwardly projecting flange or ring 31. The ring 31 is surrounded by a cylindrical part 32 which extends upwards concentrically with the lower part of the piston 27. The upper end of the cylindrical portion 32 is bent inwardly at 33 to form an inwardly facing annular shoulder 33. A compression spring Jh is disposed between the upper surface of the flange 31 and the lower surface of the boss 33. The arrangement is such that the spring J> k is constantly compressed between the parts 31 and 33, so that the force of the spring is directed to push the piston downwards. It is necessary that the piston 27 and the cylindrical part 32 be non-rotatable with respect to each other, and for this purpose the wall of the part 32 is formed with one or more slots or grooves 37 into which a corresponding tongue or tongues engage which protrude from the flange 31 so that the tongue moves up and down in the groove.

In the upper part of the cylindrical wall 27 an outlet 39 is provided in the form of a perpendicular slot which is not wider and is preferably somewhat less wide than the distance between two adjacent webs 19

2. When the piston is in its uppermost position shown in FIG. 1, this slot 39 runs approximately from the upper end of the cylindrical wall 27 to the lower end Ik of the webs 19, so that the slot 39 is aligned with any of the openings 21 and connects the corresponding opening 21 with the interior of the cylindrical piston 27.

Each time the cylindrical piston 27 is moved up and down again, it should be rotated by an amount by which the outlet opening 39 is aligned with the next opening 21. The rotary movement of the cylinder 27 required for this is brought about by a cam control device shown in detail in FIGS. K, 5 and t> and also shown in FIG. 1. The inner cylindrical surface of the part 23 above the part 23a is formed with an endless cam control surface, as shown in Fig.;}. This curve formation consists of alternating vertical and inclined surfaces which run away from the piston 27 and merge into one another at their lower and upper ends. Y. a vertical surface kl merges at its lower end into a narrow surface 42, which merges at its upper end into the next vertical surface ki.

For the operation of the blasting device, the pressure water line 12 is provided with a valve V through which the water pressure reaching the device 10 can be switched on and off one after the other in order to bring about the operation of the blasting device. The valve can be of the type which, due to the rotation of a valve pin or a Veutiiwelle ^; i8 works in such a way that the valve turns the water on and off one after the other with constant rotation of the shaft ^ 8 in one direction. The shaft kS can be driven by a motor which is connected to the valve shaft in a suitable drive housing, so that the setting and shutdown times of the valve are noticeable, for example from a fraction of one to one minute or also any cinder «any length of time.

from the next outlet opening of the circular circumference. In this way, every next beam is emitted in the next angular direction, and beams are generated in corresponding angular positions around the entire circumference. During this up and down movement of the piston, the spring J> k keeps the upper side of the projection 33 in contact with the lower surface of the part 23.

When the piston is rotated and advanced by the cam control surfaces, the part 32, which acts as a housing for the spring jk , naturally rotates with the piston, and the lug 33 acts as a bearing on the lower surface of the part. If this bearing lug 33 is not were present, the spring would abut the rigid part 23 and would tend to unwind without rotating and thereby causing undesirable twisting.

The pressure of the liquid through the vertical slits 27a in the piston wall is sufficient to equalize pressure differences between the liquid within the piston and the liquid in the area of the spring between the piston and the spring housing 32; and the flow of liquid from the area of the spring 3 ^; i through these slots 27a has a flushing effect and prevents the accumulation of sand, dirt and the like on the spring.

Modifications as will be apparent to the person skilled in the art can, can be made within the scope of the present invention. For example, the shape of the beam can further-

r switching cam control surfaces can be modified. Of the used here to describe the curve control surfaces The term "oblique" refers to the fact that these surfaces are not parallel to the movement of the piston; however, they do not necessarily have to be straight or flat surfaces.

It should also be noted that further modifications are made in the arrangement of the piston and its outlet opening. can. For example, the deodorant 20, instead of the Housing to be attached, as in FIG. 1, to the top of the piston 27 in the same position as in FIG be. In this case, the opening 29 on the top of the piston would be superfluous, as would the webs 19. The liquid jets would then be in the direction of the piston opening 39 under the cover 20 in the space between the Lid and body 16 are dispatched. In special situations, the circular cover 20 could also be omitted in which case the rays have been emitted from the opening 39 of the piston and the directions of the successive ones Rays would only be determined by the direction of the opening, which could be designed to cut the has the desired conductivity. In that case, however, it would normally be desirable to have at least some form of one To arrange cover directly above the outlet of the opening 39, against which the upward partial force of the pressure dor fluid pushed up by the piston pushes the upward movement of the piston against the spring force and

to support the friction of the curve control.

It should be noted that the present invention is an apparatus creates, which in an effective way a liquid or water jet intermittently in different angular directions sends and that the operation of the device can be carried out in a simple manner by means of a valve device that is switched on in the water supply. In this way the duration of each ray can be in each particular direction can be easily adjusted or controlled.
