- the screw element 72 In the area 52 of the opening 48 there are two with an external thread 66 and 68, respectively provided screw elements 70, 72 screwed. Through the screw element 72, the opening 48 is closed to the outside. To this For purposes of use, the screw element 72 can protrude in the axial direction Have contact section 74, the corresponding screwing and tightening the screw member 72 for a fluid tight seal the opening 48 provides in this contact area.
- the screw element 72 also carries an adjustment screw 76 which has a head region 78 of the screw element 72 passes through and with this in threaded engagement stands. By means of a lock nut 80, the adjusting screw 76 can be of the screw element 72 can be set.
- a biasing spring is on the adjusting screw 76 via a support plate 82 84 supported.
- To also provide a fluid-tight seal here
- the support plate 82 provides a support surface 90 for the biasing spring 84 which through Rotation of the adjusting screw 76 is changeable in its axial position.
- the screw element 70 positioned further in the opening 48 forms a Abutment for an adjusting element 92, for example in the form of a ring.
- This adjusting element 92 is in the direction of the axis A between the Screw element 70 and the cylinder element 56 positioned.
- Another Preload spring 94 acts on the cylinder element 56 such that it is in fixed contact with the setting element 52 and thus this is held in fixed contact with the screw element 70.
- the bias spring 84 already mentioned passes through a central one Opening in the screw element 70 and a corresponding central opening in the adjusting element 92 and is supported in the axial direction on one in the Cylinder element 56 slidably received piston 96.
- the piston 96 is towards the opening bottom 60 biased and is in the state shown in Fig. 2 on this Opening base 60 supported.
- One opens into the opening bottom 60 further opening or a line section 97 at which the branch line 34 is connected or which is a part of this branch line 34 forms.
- a blind hole-like opening 98 is provided in association with the line section 97 there is 96 in the piston .
- first mouth area 102 to an outer peripheral surface of the piston 96 open.
- Openings or bores 104 are provided in the cylinder element 56 corresponding circumferential positions. These are radially outward open to the recess area 62 and are radially inward in one second mouth region 106 to an inner peripheral surface of the cylinder element 56 open.
- the mouth areas 102 or / and 106 can also be summarized by ring grooves, so that an exact circumferential alignment of openings 100 and 104 is not required.
- the setting element 92 forms part of the one which is already schematic in FIG. 1 addressed sensor arrangement, the information about the temperature of the medium to be heated feeds into the fuel pressure regulator 36.
- a heat transfer medium can be located over a heat exchanger area to one related to the temperature of the heating medium in the inlet line 18 standing temperature brought and by using a feed pump, not shown or the like.

- the setting element 92 partially or completely include material that occurs in the Temperature range has a defined thermal expansion behavior. It follows that, for example, when the line 108 flowing through Medium has a higher temperature, heat on it Part or all of the adjusting element 92 is transmitted and this itself then extends in the direction of axis A. The consequence of that is that too the cylinder element 56 counter to the biasing action of the biasing spring 94 in the direction of the opening bottom 60 to be moved, since that Screw element 70 is held immovably in the direction of the axis A. If the medium is cooled in line 108, it takes heat from Adjustment element 92 on, with the result that this contract will and will have a shorter axial length.

- the consequence of this thermally conditional change in length of the adjusting element 92 and the associated Displacement of the cylinder member 56 is that in the piston 96 provided openings 100 with their first mouth areas 102 with respect to the openings 104 provided in the cylinder element 56 their second mouth regions 106 shifted in the direction of the axis A. become.
- This relative shift also changes the overlap of the mouth areas 102, 106 and thus also in the area of the mutual connection of these mouth areas 102, 106 formed Throttling effect in the transition area between the line sections or openings 97 and 64 and thus the lines shown in FIG. 1 34 and 38.
- the fuel pump 22 is operated in such a way that it has a plateau area in its production curve achieved, which means that by increasing the speed of a pump drive motor a further increase in output essentially does not occur.
- This drive motor not shown, also drives at the same time a combustion air blower so that in this working state the Fuel feed pump 22 changes the speed of the drive motor cannot induce a change in the combustion air flow rate however, can induce a change in fuel flow. This has As a result, the fuel feed pump basically works in such a way that regardless of the operation of the fuel pressure regulator 36, it is in the pressure line 30 can provide the maximum possible pressure.
- the temperature of the medium to be heated is therefore the one fed in Amount of fuel in the atomizing burner 12 increases, which is an increase in Heating output of the same.
- Fuel feed quantity can also be the speed of the drive motor increased for the fuel feed pump 22 and the combustion air blower in order to be assigned to the increased fuel injection quantity to be able to provide a correspondingly increased amount of combustion air.
- a further sensor arrangement which the temperature of the medium to be heated in the range of Inlet line detected, and corresponding control electronics in assignment an increased delivery rate for the effect of the fuel pressure regulator 36 of the combustion air blower is generated.
- FIG. 4 A modified embodiment of a fuel pressure regulator according to the invention is shown in Figures 4 and 5.
- components which components described above with regard to structure or Function correspond, are added with the same reference numerals of an appendix "a”.
- this is sleeve-like trained cylinder element 56a between the opening bottom 60a and the screw element 70a held axially fixed.
- the piston 96a stands still under the bias of the bias spring 84a, which is at the other end via the support plate 82a and an adjusting element 92a on the adjusting screw 76a in the direction of the axis A.
- the bias spring 84a Depending on those in the pressure line 30 or the branch line 34 prevailing pressure conditions becomes the piston which is acted upon by the line pressure 96a and on the other hand pistons 96a acted upon by the biasing spring 84a adopt an equilibrium position in which there is a certain overlap the mouth areas 102a, 106a will adjust.
- the setting element 92a has one comparatively short axial length, so that the support surface 90a for the biasing spring 84a from the opening bottom 60a comparatively is moved far away and in this respect the biasing spring 84a is only a smaller one Will produce biasing effect. As a result, if there is one Fuel pressure a comparatively large overlap of the mouth areas 102a, 106a can be obtained.
- the setting element 92a changes, as in FIG Transition to Fig. 5 recognizable, its axial length.
- the support surface 90a of the plate 82a axially displaced, namely in the direction towards the opening bottom 60a.
- the spring 84a is compressed more and so far will produce a greater bias.
- the Piston 96a continues to move toward orifice bottom 60a, causing the overlap between the mouth areas 102a and 106a is reduced becomes.
- This reduction in the overlap in turn means that a lower proportion of the fuel fed into the pressure line 30 can drain the fuel pressure regulator 36a, whereby the pressure in the Pressure line 30 will rise and a larger via the atomizing nozzle 14 Amount of fuel is fed into the atomizer burner 12.
- setting element 92a for example, as by Fluid supply configured in its axial length pad element can be, this fluid supply through a provided for this Fluid pump can be done.
- This fluid pump can in turn be dependent the temperature present in the area of the inlet line 18, for example detected by a temperature sensor for the supply of Print medium in the cushion-like or cushion-like setting element 92a are driven, or it can be, for example, by a corresponding Opening a valve assembly pressure medium from the setting element 92a to reduce the axial extent of the same.
- the temperature of the material to be heated can Medium in the area of the inlet line 18 are implemented in a certain axial length of an adjusting element.
- FIG. 6 shows a further embodiment of an inventive one Heater shown.
- Components described above Components correspond in terms of structure and function with the same reference numerals with the addition of an appendix "b" designated.
- the basic structure of the system 10b shown in FIG. 6 corresponds to that previously described with reference to FIG. 1. It is therefore on those that exist primarily in the area of the fuel pressure regulator 36b Differences entered.
- the fuel pressure regulator shown in Fig. 6 36b again comprises the piston 96b as a pressure regulating element, which by the Fuel pressure on the one hand and the biasing spring 84b on the other hand is.
- the Piston 96b moved so far away from the opening bottom 60b that none or only a slight overlap with the opening or openings 104b or the channels formed in these areas is present.
- the one in the area of these openings or channels 104b is then a throttling effect low, so that a large amount of fuel will flow away.
- the biasing force of the spring 84b is sufficient to a larger, for example, complete coverage of the openings To reach 104b with the piston 96b.
- the support plate is 82b supported on a piston element 152b.
- This piston element 152b is in an inner housing member 154b slidably received, which Inner housing element 154b in turn in a housing 36b, for example insert element 156b held by thread engagement.

This can, for example immerse in the liquid to be heated and its temperature detect so that in the control device 168b information about the heating liquid is present. According to this present Information is then triggered by appropriate control of the control device 168b the heating device 162b is more or less strongly excited or be warmed. According to the temperature of the heater 162b the expansion element 160b heated by this becomes its dimension change, due to the outward expansion restriction a volume change essentially towards the Opening floor 60b to or from this will take place.
- the temperature is adjusted of the medium to be heated, the preload of the preload spring 84b changed to achieve a defined outflow, so that an influence to the pressure control characteristic of the fuel pressure regulator 36b can be taken.
- a higher heating capacity i. H. is a high fuel pressure is required by appropriate Energizing the heater 162b an expansion of the expansion element 160b and an associated displacement of the piston element 152b generated. With this shift, the piston also becomes 96b in the direction of the opening base 60b, so that a there is greater coverage of the opening or openings 104b becomes.
- a lower required heating output, for example at higher temperature of the liquid to be heated has a corresponding Actuation of the heater 162b as a result of contraction of the expansion element 160b reduces the pretension of the spring 84b or the support surface 90b for piston 60b this is withdrawn.
