Circular sprinkler with rotatable sprinkler arm - made up of several sections and can be flexibly, three=dimensionally adjusted

摘要

The circular sprinkler has a rotatable sprinkler arm (12) which can be flexibly or three-dimensionally adjusted. The arm is made up of several sections which are connected by means of ball joints. Alternatively, the sprinkler arm consists of several angled and/or bent and/or flexible sections which can be connected with each other by means of couplings which can be tuned w.r.t. each other. The sprinkler arm can also be a flexible pipe of metal or plastic. The angle between the shanks and the angled or bent sections is less than 180 deg. and greater than or equal to 90 deg.
