concerning:
"oil atomization burner"

The invention relates to an atomizing oil burner a spring-loaded valve body which is attached to its mouthpiece and which can be opened to the outside.

Such burners can be used during operation Change the size of the flame and thus the power by changing the pressure with which the oil is fed to the burner.

With the known burners of this type, it is very difficult to change the type of fuel oil, because this is generally the case A change in the spring pressure is required, which is extremely difficult to carry out because the spring is located inside the oil chamber of the burner housing.

009882/1508

The object of the invention is "an easier changeover the valve spring, so that the burner can easily be switched to operation with a different fuel oil.

According to the invention, the valve spring to solve this problem is at the rear end of the Lrennergehäuses outside of the Glkanal appropriate. By adjusting the component at the rear end of the housing on which the spring rests, you can adjust the spring tension set to operation with a new heating oil, as you can also adjust the spring during operation to achieve a maximum Can adjust effect. The spring, which acts in a known manner in the closing direction of the valve, can be provided with an extension the valve spindle, which is led out through the rear end of the burner housing »

The valve spring preferably rests against a screw body which is adjustably mounted in the rear end of the burner housing, which results in a particularly easy adjustment of the valve spring.

The rear end of the burner housing can be in the form of a cup in which the screw body is mounted, as well this can be cup-shaped and completely enclose the spring, which in addition to a simple adjustment of the spring at the same time a good external protection of the same is achieved.

In addition, according to the invention, the edges of the two cup-shaped parts can carry knurled parts of the same Diameter like that of a knurled knob with which the extension the valve spindle closed at the rear outside the valve housing is. The three knurled surfaces together form a practical operating unit on the burner.

BATH ORIGINAL

The rear end of the burner housing can according to FIG Invention be provided with a lock nut part to secure a once selected setting, thereby an unintentional Changing the spring preload during operation is prevented.

The invention will be explained in more detail below with reference to the accompanying drawing, which shows a Shows an axial section through an atomizing oil burner according to the invention.

Oil is released through a channel 1 in the housing 2 of the burner fed, which in a chamber 3 to one with a after rearward extension 5 provided valve spindle 4 flows. The valve spindle carries a conical body 6, which rests on a suitably designed seat at the end of the chamber 3, and behind the valve body carries the spindle 4 a helical body 7 which gives the oil flowing through a circular motion.

The oil is the channel 1 through a pipe, not shown at a pressure high enough to open the valve body just enough to produce a flame of the desired length is achieved. By changing the oil pressure you can adjust the flame length and thus change the output of the burner. Does the If the oil pressure falls below a certain value, the valve closes under the action of a helical compression spring 9 placed around the rear end 8 of the extension 5 Spring sits between the bottom 10 of a threaded 11 cup-shaped part 12 which is screwed into the rear part of the burner housing, and a thrust washer 14, which presses against a pair of lock nuts 15 on the extension 8, which through a pair of stuffing boxes 16 na <£ i at the rear of the ö! chamber 3 is led.

By turning the knurled edge 17 at the end of the Part 12 can be moved lengthways in part 13 and thereby adjust the preload of the spring 9.

When changing over to operation with a new heating oil, the spring can be pre-tensioned before or during this operation Adjust so that a given oil pressure corresponds to a specific, desired flame size.

The knurled edge portion 19 of the part 13 can consist of a exist separate ring, which forms a lock nut with the part 13 for fixing the part 12 in any desired Location.

If dirt settles in the valve so that it cannot close completely, you will get through Pressing the knurled button 18 on the end of the extension 5.8 can easily blow in the valve. This extension can Incidentally, rotated independently of the spindle 4, but not longitudinally displaced.
