Abstract

A nozzle intended for a jet-pipe working with a pressurized liquid with said nozzle comprising a throttle valve head surrounded by an orifice sleeve and being pendulum-like supported by a longitudinal shaft pointing in counter-current direction, wherein the orifice sleeve constitutes one of two sleeves being rotatably journalled on each other, one of the sleeves having a runner being in mesh with a guide in the other one of the sleeves, the guide having a pitch in order to give the valve head a positively controlled axial movement by rotating the sleeves in between, the shaft is supported by a transverse shaft which extends in the diametrical direction through the inner sleeve, the transverse shaft extends through the wall of the connection sleeve into the guide, the latter being constituted by a slit made in the orifice sleeve .

Claims

1. A nozzle intended for a jet-pipe working with a pressurized liquid, said nozzle comprising a throttle valve head, a longitudinal shaft extending in a countercurrent direction, having a lateral opening and being adjustably connected to said valve head, a pair of sleeves being rotatably journalled on each other, one of said sleeves being an orifice sleeve surrounding said valve head and having a guide slot, the other of said sleeves having a pair of opposed openings with one of said opening communicating with said guide slot, a transverse shaft extending through said longitudinal shaft lateral lateral opening, means for pivotally supporting said longitudinal shaft on said transverse shaft for swingable movement in any direction, said transverse shaft also extending through said other sleeve openings into said orifice sleeve guide slot, and said guide slot having a pitch such as to give said orifice sleeve a positively controlled axial movement upon the rotation of said orifice sleeve.

2. A nozzle as claimed in claim 1 wherein said longitudinal shaft has a threaded opening communicating with said lateral opening, said transverse shaft has an annular central groove and a lockscrew is in threaded engagement with said threaded opening and has a pointed end extending into said annular groove.
