Nozzle body for Rainigen from Hohren and Sewers

The brewing pattern concerns © inen nozzle body for legging Drilling and sewing channels, the body through the beaktioai effect of the supplied pressurized water exiting from several nozzles is pushed forward in the channel.

In the case of nozzle bodies of this type, the desired effect essentially depends on the manner in which the body is guided in the channel, so that the most intensive cleaning effect possible can be achieved. Above all, there is a certain central point, if possible in the drilling or To strive channel axis extending guide because then most likely, given the guarantee that the t _t Is covered with mud channel walls are applied uniformly by the jets and all · - sided sludge separation takes place "

However, this requirement could with the previous statements of Nozzle bodies only with an increased amount of time when cycling several times to be met in the channel, in particular because of the arrangement and the position of the nozzles did not quite meet the practical requirements.

This deficiency is caused by the present utility model fixed that on each side at the same distance from the central axis of the nozzle body is arranged at least in a rearwardly drawn nozzle channel, the axis of which is the longitudinal axis of the body cuts at an acute angle, and that above the plane d «r" ' Nozzles at least one further "backward directed nozzle channel" is arranged, the axis of which is inclined in the thrust direction runs down.

As a result, in addition to the previous forward-pushing effect, the. additional effect is achieved that the path of the Düsenkörpars more than previously runs centrally, so that the Eeinigungseffakt is enhanced or accelerated "Simultaneously with the centering '* from the side, a pressing body from above, is carried out" as also to stabilize the leadership

In order to be able to use this principle with advantage also with nozzle bodies for larger pipe and channel diameters, according to the utility model, the nozzle body is arranged on both sides at the same distance from the central longitudinal axis and in a common plane with the body, two nozzle channels each. over which the "" backward and obliquely downward directed nozzle is provided.
