摘要： A rotary sprinkler comprising a rotor (16) with an axle (38) having a tip, and a thrust bearing (14) with a socket (26) having a bottom (30), the socket being adapted to receive for rotation the axle so that the tip abuts the bottom in a contact zone. The sprinkler further comprises a hard element (42) constituting a part of the bottom or of the tip. The hard element (42) is made of harder material than the axle or the socket, thereby reducing their wear.
摘要翻译：一种旋转喷洒器，包括具有具有尖端的轴（38）的转子（16）和具有底座（30）的插座（26）的推力轴承（14），所述插座适于接收以使所述轴旋转尖端邻接接触区域中的底部。喷洒器还包括构成底部或尖端的一部分的硬元件（42）。硬元件（42）由比轴或插座更硬的材料制成，从而减少其磨损。

摘要： An integral in-line dripper to be used bonded to the internal surface of an irrigation pipe. The dripper has an inlet facing the inside of the pipe and an outlet connected to an exit opening in the pipe wall. The dripper has a flattened shape defined between a first surface with an open meandering channel formed therein, the channel's inlet being connected to the dripper's inlet, and a second surface opposite the first surface. The topography of the first surface is so designed that the dripper can be bonded to the internal surface of the pipe in any orientation about a radius of the pipe passing through the first and the second surface, so as to form a flow-restriction labyrinth connected to the outlet of the dripper.
摘要翻译：用于连接到灌溉管内表面的整体式在线滴水器。滴水器具有面向管内的入口和连接到管壁中的出口的出口。滴液器具有限定在形成于其中的开放曲折通道的第一表面之间的平坦形状，通道的入口连接到滴液器的入口，以及与第一表面相对的第二表面。第一表面的形貌被设计成使得滴管可以围绕通过第一和第二表面的管的半径以任何方向结合到管的内表面，以便形成流动限制迷宫连接到滴水口的出口。

摘要： A low-pressure drip irrigation system, comprising: a distribution pipe made of collapsible sleeve with a plurality of holes in the walls thereof; a plurality of branch tubes equipped with low-pressure drip emitters; and a plurality of connectors, connecting the branch tubes to the holes of the distribution pipe. The sleeve is made of opaque and reflective material that prevents the growth of algae and heating. The holes may be prefabricated or made in the field by a hand-held tool. The connectors have a base part with two protruding collars and a narrow neck therebetween, for mounting in the holes with the first collar inside the distribution pipe. The second collar may be formed as a separate threaded member. The base part of the connector may be enclosed in a pliable sleeve providing tight connection to the hole's edges. A method for assembly of the drip irrigation system includes deploying of the distribution pipe in the field, filling the pipe with water, cutting holes in the pipe by means of the hand-held tool, and inserting the connectors into the holes of the distribution pipe to attach the branch tubes.
摘要翻译：一种低压滴灌系统，其特征在于，包括：由可折叠套筒构成的分配管，其壁中具有多个孔; 配备有低压滴水发射器的多个分支管; 以及将分支管连接到分配管的孔的多个连接器。套筒由不透明和反光材料制成，可防止藻类生长和加热。孔可以通过手持工具在现场预制或制造。连接器具有基部，其具有两个突出的凸环和在其间的窄的颈部，用于安装在分配管内的第一轴环的孔中。第二套环可以形成为单独的螺纹构件。连接器的基座部分可以封闭在柔软的套筒中，提供与孔边缘的紧密连接。一种组装滴灌系统的方法，包括在现场布置分配管，用水填充管，通过手持工具在管中切割孔，并将连接器插入分配管的孔中连接分支管。

摘要： Drip irrigation pipe (10) comprises drip irrigation emitter units (12) bonded thereto, the pipe (10) being made of water-impervious material and having foamed closed-cells therein. The drip irrigation pipe (10) may be used in a piping package comprising also a spool. The length of the pipe (10) and the number of the emitter units (12) in the package are greater than those which the package of the same weight with the same spool would have, if the pipe (10) was made of the same material but not foamed, and had the same outer diameter and about the same thickness.

摘要： An irrigation pipe (10) with a plurality of connector elements (14) adapted for attachment of lateral branches thereto, where the connector elements (14) are integrally fitted to the pipe's wall during the manufacture. Connector elements (14) may be fitted open and be adapted for closing after manufacture if not intended for use, or may be fitted closed and be adapted for opening after manufacture to enable the attachment. A method of production of such irrigation pipe (10) from a strip of flexible weldable or bondable material includes fitting integrally the connector elements (14) to predetermined locations on the strip, with or without punching the strip; bending or twisting the strip so as to juxtapose or overlap lateral edges thereof; and welding or bonding integrally the edges so as to obtain a closed pipe section.
