In the various figures, the same parts are identified by the same reference symbols.

Preferred embodiment of the invention, as shown in the drawing, relates to a fuel tank 10, which is made of two drawn sheet metal parts. One part forms an approximately right-angled seamless trough 11, the corners of which are rounded, the other a ^ corner 12. The upper The wall part of the trough 11 has an outer shoulder which forms a flanging 13 which widens the trough somewhat horizontally. The cover 12 is in the form of a cover plate, which has a extending, uninterrupted flange 14 connected to it on its circumference. When the lid covers the trough, the flange 14 lies directly over the flange 13 and is held on it at certain intervals by means of slotted nuts 15. -The parts 11 and 12 are still lashed and covered with an epoxy resin or a 909843/0389

equivalent sealant sealed between the resting "edge of the flange H and the adjacent surface of the flange 13 has been painted. In this way the invention provides a very simple fuel tank, which does not require any welding at all isto

At one end of the cover 12 an attachment 17 has been formed which has a fuel filler neck represents for the tank 10. At the longitudinal distance from the filler neck 17, towards the center of the lid 12, is located a vertical projection 18, which represents a fuel outlet nozzle.

On the lid 12 and between the filler neck and the outlet neck 18, a little closer to the latter lying down, a motor stand is attached.

As can be seen from the drawing, the stand is Iy made from a single strip of metal. It has parallel legs 20, which are constructed in such a way that that they are perpendicular to the cover 12 upwards.

the

909843/0339

The legs 20 so arranged are at their upper Jände through a curved, concave strip-shaped 'J-'eil 21 connected to each other. On its lower volume each leg 20 has a right-angled foot 22, with the aid of which the support 19 on the cover 12 is attached. The support 19 forms a motor support, its strip-shaped part 21 being the cylindrical Housing of a motor 23 carries "

Each of the legs 20 has a horizontal slot 24. The elongated holes 24 are in a common, generally parallel to the upper surface of the ■ Lid 12 is arranged lying above. In each of the A hook 25 protruding from a curved strip element 26 engages elongated holes 24. -L> ie strip parts 26 are designed so that they have an opposing curvature, which makes them the motor housing partially encircle the support 19 on both sides. Their upper, neo-adjacent outeri iinden 27, which lie above the motor 23, are bent so that they are at a certain distance protrude parallel to one another and perpendicular to the surface of the cover 12, - ^ ie parts 27 are in the usual way by a single screw 28

909843/0389

connected to each other and hold the engine 23 opposite the support 19 and the fuel tank 10 in a certain location.

The motor 23 is of conventional design. It consists of a tubular stator housing 30 which is attached to the one end is closed by a plate 31 and at its other end by a plate 32. being The rotor (not shown) has a drive shaft 29, the respective ends of which are in the - ^ ndplatten 31 and 32 and jut out through them.

The one protruding, outermost shaft end 29 carries, firmly connected to it, a series of blades that form a closed fan unit 33, namely in a certain distance from the plate end 31 and opposite this. -As other outer-eaters V / elle lies within the apparatus and, mounted on it, carries a disk-like pump rotor 34. The rotor 34 is installed in such a way that its one end face is immediately adjacent to the outer surface the -rindplatte 32 is located.

The rotor 34 is rotatably mounted within an eccentrically arranged ring 35, on the one

909843/0389 dtirnaeite

- ο -

The end face is closed by the end plate 32 and on its outer end face by the plate 36 covered. The thickness of the ring 35 is chosen so that the plate 36 is immediately adjacent to the outer Face of the rotor lies.

From Fig. 4 it can be seen how the rotor in the • "! Ng 35 is arranged »The top part will always lie against the inner surface of the ring. subject the gap between each side of its housing grows Rotor and the inner surface of the ring progressively to the deepest in a known manner Point of rinkes to reach a maximum.

The rotor 34 is a winged rotor, of the same size radially aligned oehlitze 40 at a distance of 90 from each other. Each slot 40 houses a relatively slidable iM'igel 41. How from Ji'ig. 4 it can be seen, the wave will be 2y as soon as the motor 23 current is supplied to drive the rotor 34 and thereby on the displaceable Wings act ^ that they move one after the other from the

Rotor scope

909843/0388

Rotor circumference move outwardly and thereby the gap between the rotor and the inner surface of the fi-inges 35 bridge "The purpose of this construction will become apparent below.

On one side of the motor 23, an L-shaped support 42 is attached to the cover 12. The upper bark of the support 4-2 carries a housing 43 which forms an air chamber 44. The side of the housing 43 'which is completely outside with respect to the ring 35 is open and bridged by an air filter 45 _{or the like}

As can be seen from FIGS. 2 and 4, the ring 35 has a radial opening 46 which receives one end of a tube 47. The outer end of the tube 47 is fastened in such a way that it protrudes into the air chamber 44. As the rotor 29 turns, the rotor equipped with vanes will cause static air to be sucked from the vicinity of the air filter 45 into the housing 43 and through the tube 47 into the compression space 48, which is circumferentially between the rotor and the inner wall of the ring 35 lies. As auö Fig. 4 can be seen, begin

wing 909843/0 3 80

Wings as soon as they are at the top of the ring

35 have moved past to slide out of the rotor surface to the outside, as far as this is possible due to their distance from the inner surface of the ring. ^ü ^ nce each 'begins lügel, to the outside to push, it passes immediately thereafter the air inlet opening 46, flows into the air thereby scarcely 4Ö. This air is taken up by the following wing and pushed in front of it in order to move with it through the compression space 48 after initial expansion and subsequent contraction the narrowing of the gap between the Ko toi · and the inner ring surface back into the rotor 34. As a result, the air is then compressed in front of the receding wing until it has an access point to an outlet opening 49 in the cover plate

36 reached.

With the plate 36, the body 50 is a burner head it 51 is connected in such a way that it forms an axial extension of the i-Iotors 23 and the Hinges 35.

Of the

909843/0389

The body 50 has a cylindrical i ^l orm and has an axially aasgerichteten flow passage 52 whose inlet end is connected to the outlet opening 49 in the cover plate 36th The other of the flow channel 52 is arranged in such a way that it runs out tangentially against a wall 53 formed by a cylindrical recess 54 in the upper part of the body 50. A disk-shaped filter plate 56 lies on the bottom 55 of the recess. The plate 56 is porous and is preferably made of polyurethane. In the recess 54, arranged above the filter plate 56, a second filter 57 rests. The filter 57, which preferably consists of - ^ iIz, has a tubular shape, ^ s has radially protruding, longitudinally extending ribs 58, the protruding ends of which abut the wall 53 of the recess and form vertically aligned air channels 59 with it.

The recess 54 is closed by a plate 60 which has a central opening into a vertical recess which is formed by the inner wall of the filter 57 passes. On the part of the

plate -909843/0389

Plate 60, which has this central opening into the interior of the filter 57, has a cylindrical housing 62 of an overflow valve 63 attached thereto. The housing 62 has a central recess 64 which in its interior narrows in stages up to a conical shoulder 65 around a central opening 66 in its bottom. A ball valve part 67 rests on the shoulder 65. A centrally bored shut-off member 68 is inserted into the valve housing 62, specifically in the upper cable of its recess 64. The inner end of the shut-off member 68 is countersunk in such a way that one end is on a helical spring 69 rests, and the other end rests against the ball valve part 67. In this way the i'eder 69 has a bias that forces the ^v-67 entilteil usually tightly seal the overflow opening 66 in the bottom of the valve housing 62nd

The body 50 houses the burner head 51 with an operating side End face 70 which has a central recess 71. The bottom of the recess 71 has a short conical projection in its center

72

909843/0389

72, the outer end of which is just before the operational side End face 70 ends, -ß-uch has the body 50 a central channel 73 'which is axially aligned. The channel 73 opens on its outer cortex through the center of the protrusion 72, while its interior ends within the body 50 at the intersection with a downwardly directed fuel line 74.

The channel 73 narrows progressively in its cross-sectional dimension from its outer & near the projection 72 to its inner end, which intersects the channel 74 and establishes a connection with it. As a result of this reduction in cross-section, the channel 73 has steps 75 »76 and 77 one after the other and at certain intervals, the latter two being approximately conical and being relatively close to one another and close to the channel 74. The body 50 also has a vertical flow channel 78 which establishes a direct connection between the recess 54 and the channel 73 in front of the shoulders 76 and 77. A thread is connected to the body 50 in the outer one

909843/0389

U5U13

A suction nozzle 79 is connected to the recess 73, the head of which rests against the outermost part of the projection 72. The outlet end of the nozzle 79 is arranged somewhat in front of the end face 70 on the operating side. As can be seen from FIG. 7, the nozzle 79 contains a thin tubular shaft 80 which extends into the interior of the channel 73 and is in communication with the flow channel 74 at its innermost end. In addition, the nozzle shaft part 80 has been reduced in its cross-sectional dimension from a point which is adjacent to the nozzle head and is at a certain distance from it, in order to equip it with an outer shoulder 81. The diameter of the nozzle shaft 80 is in any case substantially smaller than that of the channel 73 through which it extends. The shoulder 81 is located coaxially PARAGRAPH to ^A 76 in the recess 73 and tapers him conically at a certain distance from, -fc ^ in tubular seal ring 82 whose one ^ walls, is mounted on the inner part of the nozzle shaft so that its tapered The end of the paragraph 77 rests. The shoulder 77 is located on the inner ünde of the recess 73 and

right away

909843/0389

immediately next to the fuel channel 74 which opens into it. A flat sealing ring 83 is inside of the nozzle shaft arranged so that its one end face is in contact with the shoulder 81, while its other end face at one end the coil spring 84 is applied. The other - ^ nde of the spring 84, which is roughly concentric around the shaft is arranged, lies on the outer - ^ nde of the sealing ring 82 near paragraph 76. ^ he sealing ring 82 consists of a plastic, deformable material. Taking advantage of this characteristic Property of the sealing washer 82, the preload of the spring 84 is set high enough so that the sealing washer is plastically deformed and caused to stretch, namely transversely to the axis, so that it forms a seal for the channel 73 along the nozzle shaft and thus prevents that air from the recess 73 enters the flow ska na 1 74.

As already mentioned, the fuel channel 74 has the function of a channel that the inner part of the

Nozzle shaft

909843/0389

Düaensohaftes supplied with fuel. The nozzle juice has an inner flow channel that starts from the nozzle head. The head of the nozzle 79 is conventional Formed so that it has turbulence channels, one of which faces the inner one Flow channel opens. The other cortices of the vortex canals open to incisions 85 in the outer part of the nozzle shaft. These swirl channels ensure an influx of air under pressure into the inner flow channel of the nozzle 79, and in such a way that fuel from the sink 10 is sucked in and sucked through the channel 74, and that the fuel in tiny droplets is atomized and entrained to be expelled from the head of the nozzle 79 along with the air. The discharge takes place at a point which is directly in front of the combustion head 51 and immediately next to the one on the operating side End face 70 of the burner head 51 is located.

The flow channel 74 extends from the bottom of the body 50 through a vertical tubular projection 88, in which a tubular union nut

909843/0389

89 is screwed in. The outer inside of the union nut 89 is in the exhaust port end of a combustion

fabric-loop or tube 91 inserted. The administration 91 runs from the burner head 51 through the outlet 18 in the cover 12 and ends in the interior of the trough 11, close to its bottom. In the upper end of the fuel line 91 is in the line of the union nut 89 a cylindrical lower part 92 is used. The upper end of part 92 is in a known manner cut out in radial and axial sighting.

The body 50 also possesses from its surface a continuous channel 93 from the front runs to the back and at a certain angle is inclined, namely towards the middle, so that it is at its front - ^ end towards the recess 71, next to the conical projection 72 opens. Inserted in the body 50, there is one in the channel 93 Ignition device 95 · The ignition device 95 has an insulating part 94 ·, which is the protruding electrode 96 contains. The outer tip of this electrode is next to the front part of the nozzle head. Of the

Body 909843/0389

145H13

The body 94 carries a metallic sleeve 97 on the outside, which is conductively connected to the body 50, the made of metal. At one end there is a leading position Connection to the sleeve 97 and something protruding from it a wire-like grounding element 98 attached. The grounding element runs next to and usually parallel to electrode 96, to a point near the end of the electrode. At this point the protruding portion of the wire 98 is first at an angle against the Electrode bent so that a small gap is formed between the two and is then turned outwards, deflected away from the electrode in a V-shape. This instruction results in a simple ignition device, which provides a relatively short spark gap and allows the use of a fan-shaped cavity. It allows the use of a low ignition voltage (5000 volts) instead of the usual high one Voltages (10,000 volts) and the generation of a large ignition energy in the one described below Way.

From Fig. 5 it can be seen that ale recess 71 is limited by a mostly approximately cylindrical shaped and ^w. From the inner surface of this wall, arcuate fingers 101 protrude. The fingers 101 are curved in the same ^lv ichtung, it that at the periphery of the recess 71 form a series of pockets 99, which are surrounded by arcuate wall portions 100th The wall which forms the recess 71 on the circumference also has slots 102 at a certain distance and at a certain angle around the circumference. The slots 102 are oriented so that they form an air inlet into the pockets 99 from the circumference, and in a tangential direction to the arched wall parts 100 formed by the fingers 101. It can be seen immediately that the slots 102 not only create an air inlet from the circumference to the recess 71 in order to swirl the air in the area of the nozzle outlet end 79, but that they are also arranged so that they are in the operating-side end face 70 of the body 50

It can be seen from FIGS. 3, 1 and 13 that the jar charge provides a combustion chamber arrangement 105. The arrangement 105 comprises concentric casings 107 and 111, the inner one of which is shorter and longitudinally centered with respect to the outer casing 111. At one end of the inner casing 107 is a bowl-shaped plate
106 with a central opening 108 inserted. the
Opening 108 is from a conically widening outward and into the interior of the casing 107
extending plate parts 109 limited. With the
outer part of the metal sheet 106, consisting of one piece, arranged at a certain distance around the circumference and extending radially, there are fingers that are bent so that they form flanges 110. The "flanges 110 are shaped so that they are fixed together on the inner surface of the casing 111a & liegaaa and around the inner surface at a distance from each other"

At the other - ^ walls of the inner XJinman / telung 107 is a cup-shaped Blech112 inserted is coaxial with the opening 108 in the .Blech 106 ,, central opening 113. The plate 112 has radia / 1 outstretched pingers, similar to those in the - ⁰ IECA 106 the outer ends of which are bent over and jointly rest against the inner wall of the covering 111 and are attached to it all around at certain intervals. A baffle 114 is adjacent to the outside of the hole 112, which has a conical neck-shaped surface immediately next to the opening 113 in the oil hole 112. The J3leeh 114 has radially protruding fingers lying in one plane, which rest on the radially protruding fingers of the plate 112 and are attached to them in a known manner. The conical, rounded part of the plate 114 extends in the middle, towards the adjacent - ^ nae of the outer cladding 111, which is covered by a converging, nose-shaped hood 115 -is. The nose-shaped hood 115 has a central opening at 116.,

the end

On the surface of the sheet metal 106, at the greatest distance from the nose-shaped hood 115 », arms are attached which are radially spaced from one another and the protruding parts of which form the cylindrically bent sheet metal 117. If one connects the plates 117 to each other, they form a tubular projection, the public-wes in extending against the adjacent end of the shell 111th On one edge of the arched sheet metal projection; 117 there is a curved extension 128, the protruding edge of which has an incision at 119, the shape of which is adapted to a bolt 103 or 103 'on the burner head 51.

The combustion chamber 105 is assembled so that it is closed on the circumference and that it is axial Extension of the separator unit described above daretellt, in which their oil parts 117 with the bolts 103 and 103 'are locked on the burner head 51

to set the combustion chamber opposite the burner unit. When assembling the arrangement 105 with the burner unit, the one end of the arrangement 105 which is closest to the burner unit is placed on a support 129 designed as a support, which is fastened on top of the cover 12 of the fuel tank 10. The protruding part the assembly 105 extends in the same direction as the lid 12 and is attached to the lid 12 by a bracket 120, as shown in S ¹ Xg. 1 can be seen. The structure 105 and the inner cylindrical jacket 107 together with the - ^ ndbleche 106 and 112 form a combustion chamber 121. The inner surface of its outwardly widened part 109 of the sheet 106 includes the frontal working surface 70 of the burner head 51. In addition, the concentric, cylindrical ones form Jacket 107 and 111 have between them a tubular air passage 118 which can be used in a conventional manner.

In the embodiment described above, is on

to the

909843/0389

the cover 12 has a suitable connection device to the energy source, the energy supply of the motor 25 is used. As soon as the motor 23 starts, the drive shaft 29 sets the fan unit forming wing together with the rotor 34 in motion. The blades 33 generate a stream of compressed air, which flows outside of the burner unit and forward in the direction of the burner unit penetrates to the burner head and through the tubular passage 118 that exists around the combustion chamber 121 is to flow and as heated air through the central opening 116 in the nose-shaped hood 115 to exit * The vane rotor 34 rotates constantly in its housing, which is supported by the ring 35 »of the motor end plate 32 uad. the cover plate 36 is formed. if if the rotor rotates, each slide 41 moves on the upper four, immediately adjacent to the rotor Bottle of the ring 35 over, is located shortly thereafter above the opening 46, moves past it and allows suction or inflow of Ruheader detention, which through the air filter 45 in the Chamber 44 is sucked and through the pipe 47 in the compression space 48 in the path of the following

iaohiebers 909843/0339

Slider 41 flows in, since each slider 41 rotates with the rotor 34, he will push himself out of the rotor as far as the eccentric ring allows. The slider 41 to move the air in front of them in a widening at the beginning ^x eil of the compression space 48 and out through a correspondingly tapering portion of the compression space, is accommodated in the cover plate 36 until this air to the outlet opening 49th

As mentioned above, the opening 49 is with the Flow channel of the burner 52 in connection * whereby it is achieved that the compressed air that the ^ ompression space 48 leaves, tangential to the inner wall 53 of the recess 54 in the burner head 51 flows out. The longitudinal channels 59. » those from the second filter. 5? iü the recess 54 are formed, facilitate., the tangentiaie inflow of compressed air, fli-e swirls around the filter, penetrates and gradually flows into the interior of the filter, removing the air from soot particles is released. When the air is the middle of the Recess 54 within the tubular filter

909843/0383

57 reached, it flows through the floor filter 56 into the air duct 78, which is connected to the recess 73 in the Front face of the burner head 51 is in connection. The air will flow into the recess 73 under pressure, move around the shaft 80 of the nozzle 79, then Uffl into the slots 85 in the outer shaft part penetration. During its passage through the slots 85, the compressed air swirls through the Channels in the nozzle head to get into the interior of the nozzle head flowing through Brenrxstoffströmungskanales. As soon as this pressurized air inside the main flow channel through the nozzle 79 is in a turbulent motion, it will create a negative pressure and out of the tank 10 Suck in fuel that rises through line 91, through filter 92 and into the interior of the Flow channel 74 flows and then through the outflow channel flows in the nozzle shaft. The in the flow duct Turbulent air entering the nozzle not only sucks the fuel through the duct, but also atomizes it, whereupon it takes it and thus causes the fuel with it exits the nozzle in a foggy state.

This 909843/0389

This exit takes place immediately in front of the front-side operating area 70.

It should be noted that the successive filtering of the air that is on its way to mixing takes place with the fuel, retains essentially all of the impurities that would normally occur an unimpeded flow of the entrained fuel through the nozzle 79 and its completion Combustion in chamber 121 would interfere. In addition, the installation of the pre-stressed sealing ring 82 enables a very effective sealing of the channel 74 against the recess 73. These Sealing prevents air from entering the channel 74, which increases the efficiency of the created Decrease air and fuel delivery system would.

How special from 'Pig. 7 as can be seen, the arrangement of the filters 56 and 57 is such that the for Purposes of cleaning and renewal are very accessible. The check valve 63 is for this

provided 909843/0389

provided, a good control of the pressure under which the air is conveyed into the recess 73, to ensure.

As previously mentioned, the fan 33 forces air past the burner head and inside the combustion chamber assembly 105 through the tubular duct 118 to thereby heat and expel it. When the air flows past the burner head, a '^ eil caused by it to swirl through the ^u chlitze 102 to the inside and engage in the recess 71 tangentially to the surfaces ^ inger 100th This increases the turbulence of the air flow. The air entering the recess 71 swirls within the recess and moves around the nozzle 79 to the outside. This has the effect that the fuel mist flowing out of the J-Hise is entrained, creating an additional amount of air for the combustion, furthermore a stronger misting of the fuel-air mixture as soon as it emerges from the J-Hise and an additional increase in the air flow

909843/0289

^U5U13

in seal on the combustion chamber 121. This The flow takes place through the plate 106 and is thereby controlled by the edge of the widening outward Opening 108 out.

The ignition electrode 95 ″ has a number of prepared and fixed points. The gap which is formed by the end of the electrode 96 and the part of the ground connection 98 which strives from it lies immediately in front of the outlet end of the nozzle 79 See at the inner end of the Y formed at the protruding ends of the electrode 96 and the grounding part "98, under the influence of the air moving from the recess 71 there through, between the diverging files of the electrode and the earth to the outside blown. In this way, using only a relatively low voltage, one can create a spark of maximum volume. This ensures a very effective ignition of the very well atomized fuel as it emerges from the nozzle 79 b & a point which is immediately behind the entry into the combustion chamber ^! lies. The characteristics of the improved

ignition

909842/0289

Create ignition together with the effective external use of the air supplied to the burner head 51 substantially complete combustion of the fuel in chamber 121 with almost no detrimental effect Residue. There is very little after-smoking, but optimal heating of the air that comes through the chamber channel 118 flows and exits through the opening 116 in the nose-shaped hood "

It should be noted that the present ignition device, in contrast to the conventional - ^ ineatz two set electrodes contains only one electrode.

The embodiment described above has many Features that improve space heating elements and assemble them into a single, compact one Show unity. As shown in the first example, the device and the way how the air is brought to and through the nozzle 79 is important. The way in this is achieved, makes it possible to dispense with many metal parts, and acts the appearance

909843/0389

against impurities which usually cause an undesirable residue in the burner unit and its structural parts. Furthermore, the fuel control and ignition achieved are of considerable importance to the development of improved space heaters. Another, predominant M _e rkmal is the simple device with which the burner unit and the combustion chamber are mounted on a base structure, which represents an improved -brennstofftank. In addition, both the way in which the nozzle is accommodated in the burner and the design of the burner head itself facilitate maintenance work and enable the burner units to be manufactured extremely economically.
