Add Pin behavior to Particles object. After your spawn them and set their angle, in the same event add "Particles Pin to Sprayer" action.
Now particles will be attached to the sprayer, and will move and rotate with it.
I tried, but it's not something slightly what I need. I don't have a problem that they are not rotating with the "sprayer", but that when the sprayer rotates, the "particles" leave their angle in -90 and 90 degrees. When the sprayer does not spin and turn right, then everything works, as should, some particles are up, and others down. But when the rotation begins, then the particles begin to sprinkle incorrectly. I need, regardless of the rotation of the "sprayer", the particles are static in the desired directions.
Example: "Sprayer" will be rotated to the right "particles" spray one up, and the other down, turn down the "particles" is sprayed alone in the right, and the other in the left, etc.
