Abstract
A spraying device having a spray head for spraying at least one component comprises at least one substance component duct (6, 6′; 20), the component outlet (8, 8′; 23, 23′) of which leads out of a spray head tip (7). An annular duct (12) for a pressurized gas surrounds the at least one component duct (6, 6′; 20) at least partially in the longitudinal direction and leads out of the spray head (5) at the spray head tip (7). A pressurized gas supply duct (13) is provided for introducing pressurized gas at the annular duct (12). The annular duct (12) has a plurality of ribs (16, 16′), which divide the annular duct (12) at least in the region of the spray head tip (7) into pressurized gas outlet ducts (17, 17′) that are separated from each other.
Claims19
A spray head for a spraying device for spraying at least one substance or component, comprising:
- a spray head tip;
- at least two component outlets that open out from the spray head tip;
- at least one substance or component duct arranged in a longitudinal direction that leads to the component outlets;
- an annular duct for a pressurized gas, which annular duct at least partially surrounds the at least one substance or component duct in the longitudinal direction and opens out from the spray head at the spray head tip;
- a plurality of webs arranged in the annular duct at least in the area of the spray head tip, the webs dividing the annular duct into pressurized gas outlet ducts that are separate from one another, the webs being arranged in such a manner that the pressurized gas outlet ducts have a width between the webs that narrows in the direction of the spray head tip, the width being measured along a circumferential direction;
- and
- a pressurized gas supply duct for introducing pressurized gas into the annular duct.
A spray head for a spraying device for spraying at least one substance or component, the spray head comprising:
- a spray head tip having two oblique surfaces that are inclined relative to a longitudinal direction so as to enclose an angle between each other;
- two component outlets, each of said component outlets opening out at one of said oblique surfaces;
- at least one substance or component duct that leads to the component outlets;
- an annular duct for a pressurized gas, which annular duct at least partially surrounds the at least one substance or component duct in the longitudinal direction and opens out from the spray head at the spray head tip;
- a plurality of webs arranged in the annular duct at least in the area of the spray head tip, the webs dividing the annular duct into pressurized gas outlet ducts that are separate from one another, the webs being arranged in such a manner that for each of said oblique surfaces one of said webs is arranged adjacent to the respective oblique surface, along a connecting line that connects the component outlets, in such a way that the pressurized gas does not flow directly over the outlets;
- and
- a pressurized gas supply duct for introducing the pressurized gas into the annular duct.
A spray head for a spraying device for spraying at least one substance or component in a spraying direction, the spray head comprising:
- a spray head tip having at least three oblique surfaces that are inclined relative to the spraying direction so as to enclose an angle between each other;
- a plurality of component outlets, each of said component outlets opening out at one of said oblique surfaces;
- at least one component duct that leads to the component outlets;
- an annular duct for a pressurized gas, which annular duct at least partially surrounds the at least one component duct in the spraying direction and opens out from the spray head at the spray head tip;
- a plurality of webs arranged in the annular duct at least in the area of the spray head tip, the webs dividing the annular duct into pressurized gas outlet ducts that are separate from one another, said webs being arranged in such a manner that for each of said oblique surfaces one of said webs is arranged underneath the respective oblique surface, in such a way that the pressurized gas does not flow directly over the outlet opening out at said oblique surface;
- and
- a pressurized gas supply duct for introducing pressurized gas into the annular duct.
A spray head for a spraying device for spraying a substance, the spray head comprising:
- a spray head tip having at least two oblique surfaces that are inclined relative to a longitudinal direction so as to enclose an angle between each other;
- at least two component outlets, each of said component outlets opening out at one of said oblique surfaces;
- one single substance duct that leads to the at least two component outlets;
- an annular duct for a pressurized gas, which annular duct at least partially surrounds the substance duct in the longitudinal direction and opens out from the spray head at the spray head tip;
- a plurality of webs arranged in the annular duct at least in the area of the spray head tip, the webs dividing the annular duct into pressurized gas outlet ducts that are separate from one another;
- and
- a pressurized gas supply duct for introducing pressurized gas into the annular duct.
