| 281 | BESCHICHTUNG VON VERDRÄNGERKOMPONENTEN (ZAHNKOMPONENTEN) FÜR EINE CHEMISCHE BESTÄNDIGKEIT UND EINEN TRIBOLOGISCHEN VERSCHLEISSSCHUTZ EINER VERDRÄNGEREINHEIT | EP05810676.6 | 2005-11-02 | EP1807546A1 | 2007-07-18 | VOEGELE, Gerald; WEISENER, Thomas |
| The invention relates to a method for producing a displacer component that is coated with a diamond coating or layer as well as such a structural component (as a tribologically loaded part). In order to convey or dose a chemically aggressive fluid, a basic structural component (2, 3) is accurately produced in a first size (m1) from a chemically not sufficiently resistant but mechanically sufficiently stable first material (A) in a material-removing manner. At least the surface sections of said first accurately sized basic component (2, 3) which are actively involved in the displacement are then coated with an at least 1 µm thick layer (10) of synthetic diamond in a coating process such that a second size (m2) of the structural component is obtained that fits the displacer unit (1). The inventive method makes it possible to produce a chemically resistant, friction-reduced structural component for displacing the chemically aggressive fluid. | ||||||

| The invention relates to a pump body (10) used in a medical gear-pump for suction and irrigation. Said pump body comprises a pot-shaped pump housing (12) with two cylindrical openings (18, 20) that accommodate two meshing gear wheels (30, 42). The driving gear wheel (30) is housed in the opening (18) without using a journal bearing. A cover (16) closes the pot-shaped pump housing (12). The invention is characterised in that a pin (40) protrudes from a base (14) of the pump housing (12) and that the travelling gear wheel (42) is pushed onto said pin. | ||||||

| Apparatus for dispensing beverages formed by mixing carbonated water and a flavoring syrup are described. Dispensing takes place via a pump which is driven by the carbonated water under pressure and which has a pumping chamber adapted to pump syrup from a syrup container to an outlet. The relative sizes of the two pumping chambers determine the mixing ratio between carbonated water and syrup, outlet pipes leading to a common mixer and dispensing aperture. In a preferred embodiment, the internal geometry of one of the pumping chamber may be changed whereby to vary the volumetric ratio between the liquids pumped through the two respective chambers. | ||||||

| The invention relates to a housing construction for accommodating and bearing a microsystem, e.g. a micropump (MP) for conveying a fluid. The aim of the invention is to improve the housing construction in such a way that it is no longer necessary to produce a special housing construction for each different application. To this end, several elements of a layered structure (20; 30; 31; 32; 40; 11; 12) are provided, including at least two which extend vertically in relation to a housing axis (100). One of said layered structure elements is configured as a support plate (30) with an axially oriented recess (30a) for receiving a first and second functional element (A) of the fluidic microsystem. One of the layered structure elements is configured as a connecting block (11) for mounting an inlet and an outlet (60) for carrying fluid (F) to and from the microsystem. An additional plate-shaped layered structure element (31; 20) is located between the connecting block (11) and the support plate (30) and bears an axially oriented channel segment (20a; 31k, 31k'), a peripherally oriented channel segment (41k, 41k') or a radially oriented channel segment (20r), or a combination of at least two of these channel segment types (20a, 20r) for guiding the fluid (F) through from the connections of the connecting block (11) to the microsystem in the recess (30a) in the support plate (30) and back. | ||||||

| The invention concerns a metering gear pump comprising a set of gears (3) supported and guided solely by the inner peripheral surface of the lobe of the chamber (110) wherein they are housed. They do not comprise any shaft to act as support or guide, thereby enabling to reduce significantly useless spaces difficult to rinse when changing the product to be pumped. For the same purpose, the driving shaft (40) is flexibly (41, 300) connected to the driving gear (30). Such arrangement provides the advantage of requiring only one single packing seal (5). Such a pump, connected to a drive motor (41) and an encoder (43) delivering a signal proportional to the number of pump cycles, enables to provide an accurate metering pump for numerous uses. | ||||||

Eine Vorrichtung mit einer Zahnradpumpe (1) ist offenbart, die aus einem Gehäuse (2) und aus zwei ineinandergreifenden Zahnrädern (3, 4) besteht, wobei mindestens eines der Zahnräder (3, 4) auf einer Welle (5, 6) angeordnet ist, die durch das Gehäuse (2) nach aussen geführt ist und die mit einem Direktantrieb (7) wirkverbunden ist, der aus einem Rotor (8) und einem Stator (9) besteht. Erfindungsgemäss weist der Rotor (8) einen Hohlraum (10) zur Aufnahme der nach aussen geführten Welle (5, 6) auf. Hierdurch wird ein vereinfachter und damit kostengünstiger Antriebsstrang erhalten, der erheblich geringeren Platzbedarf benötigt als bei bekannten Anlagen. |

| The invention concerns a micropump (1) for the substantially continuous delivery of a mass flow, the micropump having a sleeve axis (101) and an offset axis of rotation (100). An internal rotor (20) meshes with an external rotor (30) in a sleeve (60) and at least one outlet-side pressure opening (42n) in a first end-face insert part (42), which is inserted into the sleeve (60) of slightly largely diameter, is aligned in the axial direction (100). The invention further concerns a micromotor (2) of similar construction in which the diameter of the delivery hose corresponds approximately to that of the sleeve casing (60, 61). The pump and motor are extremely miniaturized yet still permit a continuous flow with high feed pressure and high output. | ||||||

Die Erfindung betrifft eine Solaranlage mit in einem Solarkreislauf eines Wärmeträgermediums eingebundenen Solarkollektor (13), Wärmetauscher (5) und Zirkulationspumpe. Sie betrifft außerdem eine Zahnradpumpe (9), insbesondere für Solaranlagen zur Zirkulation eines Wärmeträgermediums, mit einem Pumpengehäuse (91), in dem zwei Zahnräder (93, 94) ineinandergreifend drehbar gelagert sind, und einem Pumpengehäusedeckel (92). Erfindungsgemäß erzeugt die Zahnradpumpe einen für eine "Low-Flow-Solaranlage" ausreichenden Betriebsdruck bei dem gewünschten relativ geringen Förderstrom. Die Zahnradpumpe sperrt bei Stillstand den Solarkreislauf, so daß eine unerwünschte Rückzirkulation mit einfachen Mitteln vermieden wird. |

A pump housing (11) is provided with a conduit (32) extending through the housing between a pump inlet (34) and pump outlet (36). A pump device (38) is disposed within the housing and in communication with the conduit to pump fluid therethrough. A fluid flow meter (42) also is disposed within the housing and in communication with the conduit (32) to monitor fluid flow rate through the conduit. The fluid flow meter generates signals related to the fluid flow rate which are fed back to a control device (50) operable to control the flow rate through the pump device. The flow meter may include a pair of meshed modified elliptical gears. The modified elliptical gears are based on a true elliptical shape, with bulged portions added between the major and minor axes of the elliptical shape. The modified elliptical gears have involute teeth that are relatively thick adjacent the minor axis and relatively thin adjacent the major axis. |
