The invention relates in particular to nozzles for large diameter pipes and for moving large quantities of water.

The use of irrigation nozzles for ordinary pipes with a straight line of 1/2 inch to 3/4 inch is known.

Such a nozzle is joined at one end with a union connected to the pipe at the other end. This coupling between the nozzle and the union consists of a quick acting coupling of the female part, in particular the union and the male nozzle.

Known types of nozzles include an inner tube casing with irrigation fluid supplied at one end and radial openings for flow out of the fluid at the other end, the outer sleeve being combined with the opening and the inner casing. It may be characterized as a moving member of communicating fluid and may or may not be threaded to open or close the central flow path in a controlled manner.

However, such known solutions are not suitable for large diameter feed pipes and for moving large amounts of water. In such cases, depending on the position of the adjustment sleeve, very long jets of water can be produced, which are characterized by high outlet pressures that harm plants or flowers to be irrigated, resulting in water jets falling or circular short-range jets. It was only possible to irrigate as far as possible.

It is an object of the present invention to achieve an irrigation nozzle which is particularly suitable for use in large diameter pipes which do not have the drawbacks mentioned above.

According to the invention, this object is achieved in the case of irrigation nozzles, in particular in large diameter pipes, consisting of first means having a main jet of variable length and shape, said first means being at one end Characterized by a radial opening for supplying the irrigation fluid and the outflow of fluid at the other end, and a moving chamber of fluid in communication with the opening with the inner casing, and dismounting the central outlet passage; Said second means being adapted to produce a plurality of secondary jets at reduced pressure around the circumference of said primary jet, said second means being a plurality of circumferentially spaced holes and sleeves. There is a plurality of similar circumferentially spaced holes to be aligned and otherwise aligned with the caps rotatably superimposed on said terminal wall of Each of the terminal walls of said sleeve with said opening of said terminal wall of the sleeve for its opening and closing with respect to its angular position.

It is thus possible for the nozzle to have a low pressure main jet or otherwise to have a circular high pressure jet in the shape of a fan as a traditional nozzle, and also to be irrigated in the case of a large diameter with or above the main jet. It is evident that an irrigation pattern with a relatively limited force can be formed to avoid damage to plants and flowers, possibly resulting in a large number of second low pressure jets, even with large amounts of movement. In this way, water can be watered near the outlet of the main jet at the same time, providing the possibility of watering very close parts, such as flower beds, while on long distances.

In the drawings, in particular with reference to FIGS. 1 and 3, the irrigation nozzle, shown generally in conjunction with reference numeral 20, is filled with the irrigation nozzle irrigation fluid at one end 2 and the outflow of fluid at another end 4. It consists of an inner tube casing 1 with a radial opening 3 for it.

The nozzle 20 is screwed into the outer sleeve 5 having the terminal wall 30 through which the circumferentially spaced holes 11 pass, the inner annular portion 26 and the inner casing 1 above. Or an external side wall 31 that can be unthreaded or unthreaded. The sleeve 5, together with the inner casing 1 above, is characterized by a delivery chamber 6 of fluid in communication with the radial opening 3. The central passage 7 for the outflow of fluid confined between the inner annular wall 26 of the sleeve and the terminal projection 27 in the form of a mushroom with respect to the inner casing 1 by screwing and screwing off the sleeve 5. Opening and closing is made about. The closed position is specified by the annular gasket 35 being applied to the base of the terminal projection 27 of the inner casing 1 to install the inner annular wall 26 of the sleeve 5. Between the inner casing 1 and the outer side wall 31 of the sleeve is fluid sealed by an annular gasket 37.

The terminal wall 30 of the sleeve 5 is provided in front of the sleeve 5 so as to be opened and closed with respect to the angular position of the cap 10 and the side annular wall 39 rotatably connected to the outer side wall 31 of the sleeve 5. A cap 10 is located which is formed by a plurality of front annular walls 39 which are aligned or not aligned with the above holes 11 of the annular wall 30. As in FIGS. 1 and 3 and 6, the rotation of the cap 10, together with the lateral protrusions 48 of the outer side wall 31 of the sleeve 5, causes the side walls 28 of the cap 10 to fall. Is allowed between the two extreme angular positions specified by the connection of the lateral projection 41.

As in FIGS. 4 and 5, the aperture 9 on the annular wall 39 of the cap 10 is surrounded by a diverging wall 42 with a V-shaped channel for each ejection direction coming out of the apertures. have.

2,3,7,8 are in accordance with patent application 19494A / 89 of February 20, 1989 of the same applicant to connect the nozzle 20 to a quick acting union 44 for a large diameter flexible pipe. Represents a system for

The union 44 is provided by a flexible pipe by a ring nut 50 which is screwed onto the spiral 53 to hold a flexible pipe fitted over a distal end (not shown) of the tubular casing 52. It consists of the tubular casing 52 fixed to 70).

The union 44 is a rib having a plurality of circumferentially spaced intervals on the circumference, each having a circumferential sliding action and continuous rotation, each having a respective seat 60 for receipt. An inner side wall 37 is provided with a plurality of axially spaced axial grooves 23 which project part in the radial direction opposite to the end 2 of the inner casing 1.

In particular, each of the ribs 22 is held inside each sheet 60 by the connection of one end 64 of each rib 22 to the shoulder 65 of each side wall 60.

In order to lock the ribs 22 in the seat 60, an adjustment cursor 24 is attached to the nozzle 20, and the ribs 23 of the union 44 in order to lock the nozzle 20 in the rotational position. There is a sliding tang (25) that can be inserted into.

In order to use the nozzle 20 it is necessary first to connect the nozzle 20 to each union 44. This operation is generated by the method known from the above patent application 119494A / 89.

In order to make the main delivery jet, the inner tube type is formed from the terminal protrusion 27 of the inner casing 1 first following the movement of the inner tube wall 26 of the sleeve 5, thereby causing the opening of the central delivery passage 7. It is necessary to rotate the outer sleeve 5 around the casing 1. The length and shape of the main effluent delivery jet is controlled with respect to the opening.

It is also possible to generate a pressure sensitive jet surrounding the plurality of second main subjects. For this purpose it is necessary to rotate the cap 10 to align the holes 9 on the front annular wall 39 with the corresponding holes 11 of the front annular wall 30 of the sleeve 5.

If desired, the second jet can replace the main by closing the central passage 7 by rotation of the sleeve 5.
