- the first pole piece arrangement with respect to the second pole piece arrangement has a rotational offset and / or axially with respect to this is offset.
- the metering pump device 10 comprises a body 12, in which, for example through an insert 14 one on one axial side - apelogen on an axis A - open and a pump chamber 16 providing recess 18 is formed.
- a valve / pump rotary valve 20 used with a tight fit, so that he ultimately the Recess 18 is essentially fluid-tight and with its axial Face 22 of the pump chamber 16 to the axially open side of the recess 18 limited.
- the Valve / pump rotary valve 20 in the recess 18 both around the axis A rotatable and adjustable in the direction of the axis A.
- the valve / pump rotary valve in the following only Called rotary valve, in adaptation to the shape of the recess 18 have a circular outer peripheral contour.
- an inlet area In the body 12 is an inlet area, generally designated 24 educated. This includes a first opening or bore 26 in the area an inlet opening 28 is open to a fluid supply. A second opening or bore 30, which is essentially in the insert 14 is formed, on the one hand opens into the recess 18 and on the other hand opens into one connecting the two openings or bores 28, 30 Opening area 32 with larger dimensions.
- a valve arrangement 34 is provided, which, for example a valve ball 36 pressed onto a valve seat by spring preload includes. This valve arrangement 34 thus essentially forms a Backflow of fluid from the pump chamber 16 into the inlet area 24, in particular the opening of the bore 26 of the same, preventing check valve.
- An outlet area 38 of the metering pump device 10 comprises in the Body 12 has an opening or bore 40 which is on its outside open end in a closed by a housing 42 or the like Volume area 44 opens.
- an opening or Bore 46 provided which is approximately at the same axial level in the recess 18 flows into.
- a valve assembly generally designated 48 provided, which in turn by spring preload on a valve seat can include preloaded valve ball 50.
- This valve arrangement 48 in turn forms a check valve that reliably prevents Fluid from the outlet area 38, in particular the opening or bore 40 of the same, flows back into the recess 18 or the pump chamber 16,
- An outlet line 52 leads further from the volume region 40 the system to be supplied with the fluid, for example one with Fuel to be supplied to the heater of an auxiliary heater of a vehicle.
- this sits in the area of an anchor 54 carried thereon with a sealing element 56 on the outlet line 52 and thus also ensures there a tight conclusion.
- FIG. 2 it can be seen that the two open into the recess 18 Openings or bores 30, 46 which are approximately the same axial level, are essentially directly opposite each other and thus have an angular offset of 180 °.
- Each of these two Openings 30, 46 are assigned to each in the rotary valve 20 extending essentially in the direction of the axis A, toward the end face 22 open and open radially outward, providing a fluid flow channel groove-like depression 58, 60 provided.
- the length of these channels 58, 60 is such dimensioned that regardless of the position of the rotary valve 20 with appropriate rotational positioning of the rotary valve 20, the openings 30, 46 always open into the assigned channels 58 and 60, respectively can.
- a biasing spring 62 is assigned to the rotary valve 20.
- This is as Screw leg spring trained and ensures by their kind Helical compression spring trained central area 64 for that by Support on the body 12 on the one hand and on the anchor 54 on the other hand Rotary slide 20 axially biased into the position shown in FIG. 1 in which it is at its maximum extent from the recess 18 is moved out and with the sealing element 56 on the outlet line 52 seated.
- the two legs 66, 68 are circumferential with respect to the Axis A is supported on the body 12 on the one hand and on the armature 54 on the other hand and take care of the torsion of the spring 62, that the rotary slide valve 20 is in the rotary position shown in FIGS.
- the actuation arrangement 70 shown schematically in FIGS. 11a and 11b includes the one already mentioned and coupled to the rotary valve 20 Armature 54. Furthermore, one is connected to a coil, not shown standing yoke 72 provided.
- the yoke 72 has two pairs of each other with pole shoes 74, 76 and 78, 80 opposite each other on. 11a that the two pairs of pole shoes can be seen 74, 76 and 78, 80 have an angular offset to one another.
- the arrangement is such that in the second rotational position located rotary valve 20 and in a corresponding rotational position located anchor 54, which rotational position is shown in Fig.
- the armature 54 with its long body axis B orthogonal to the axis A to the pole pieces 74, 76 is rotated in the range of about 45 ° while he to the pole shoes 78, 80 is rotated in the range of about 90 °.
- the level lies like the pole shoes 74, 76 and therefore also due to them of the smaller angular misalignment has a smaller distance than to which are both more angularly offset and axially larger Pole shoes 78, 80 positioned at a distance.
- the characteristic curve kinks c significantly and makes the displacement movement in the direction of the axis A up to Visible at point b.
- the point b means the positioning of the rotary valve 20 in the second shift position and in the first Rotational position.
- the aforementioned angular misalignment between the pole shoe pairs 74, 76 on the one hand and 78, 80 on the other makes a significant contribution to the kinked characteristic curve c since the pole shoe pair 78, 80 can essentially only become effective, if the first rotational position, that is to say in the illustration in FIG. 15, is an angle of rotation of 45 °. Because of the always in the first rotary position still existing angular misalignment between the armature 54 and the Pole shoes 78, 80 could still tend to over anchor to turn this first rotary position out. This can be done, for example the provision of a rotary stop can be counteracted.
- the metering pump device is in FIG. 1 10 in a non-energized state of the actuator assembly as shown has been described above. That is, through pretension the spring 62 of the rotary valve 20 is in its first displacement position and its second rotary position. The entrance area is in this position 24 via the channel 58 in connection with the pump chamber 16, and by the fluid pressure (overpressure) prevailing in the inlet area 24 or the negative pressure prevailing in the pump chamber Check valve 34 is opened and fluid flows into pump chamber 16 or has already flowed in. Then the actuation arrangement excited, it generates, as on the basis of the characteristic curve c in FIG. 15 recognizable, initially essentially the armature 54 and the rotary valve 20 rotating force.
- the dosing pump device 10 is then again in the position which can also be seen in FIG. 1, d. H. the rotary valve 20 is in the first shift position and the second rotary position.
- the armature 54 or the sealing element carried thereon 56 sits on the outlet line 52 and closes it off.
- the present invention provides a metering pump device which due to the fact that it has only one organ, that to provide the valve function and to provide the Pump function must be moved, very simple and very is easy to operate. Furthermore, through the interaction this single organ in particular with the two described Valve arrangements or check valves ensure that in the movements defined in different operating phases, for example Rotational movements or displacement movements occur. This will be particularly when the actuation arrangement is excited by the actuation characteristic the same still supported, so that especially during the transition from the first shift position and the second rotational position to the second Shift position and first rotary position a relief for that Valve arrangement assigned to the inlet area can be provided.
