Definitions
- the invention relates to a method of a rotary piston machine, or a manufacturing method thereof, or a rotary piston machine for performing the method, according to the preamble of the main claim (WO 05/024236 Al), claim 10 or claim 3.
- the invention is based on the object in a rotary piston engine of the generic type, in particular by overcoming the bias of the art, a -, or manufacturing process, or to develop a special construction, via which such a rotary engine can be supplied to a wide range of uses.
- the rotors have an interlocking Trochoidenveriereung (cycloid toothing).
- Trochoidenveriereung cycloid toothing
- a rotary engine is known (see type WO 05/024236 Al) with the great advantage that the remaining remaining spaces of the pump, d. H. the noxious spaces are very small, however, with respect to the invention, there is a considerable bias in the art of such trochoidal rotary engines, particularly with respect to methods of use, methods of manufacture or construction.
- An according to claim 3 to be designed rotary piston conveyor with cup-shaped canned to facilitate the replacement of the pump head is an additional thought step, which is unusual because the flowed through from the substrate to be pumped pump head forms by its invention interchangeability no conceptual link to the function of the known gap motor, because for the expert in the known pumps, the can is hermetically separated during operation, the flowing medium, the electrical part of the pump part.
- the connection between the base housing and the pump head as a Quick coupling formed, which acts on corresponding devices of the base housing and pump head.
- End surfaces between the base housing and the pump head are that the housing in the contacting area have an associated outer bead or flange and that the housing over these these beads or flanges cross tangential shortening ring are axially clamped together.
- An embodiment of the invention consists in a manufacturing method in which these plastic parts of the pump head and / or split pot tool are made falling.
- Such a preparation is particularly advantageous applicable to the trochoid toothed rotors in which rounded teeth run on smooth surfaces with linear working space limiting positive engagement between flanks and tooth combs of the opposing teeth, which accommodates a tool falling manufacturing including the housing parts of the pump head and split pot.
- Fig. 2 shows the quick-release connection between the base housing and pump head housing in plan view
- the rotary piston pump As shown in exploded view in Fig. 1, the rotary piston pump according to the invention comprises a base housing 1, with which the pump is anchored correspondingly fixed and in which the electrically controllable coil 2 of an electric motor is arranged.
- a pump head 3 In the right part of the exploded view, a pump head 3 is shown, which can be closed by a pot-shaped can 4. Between a fiashlike portion 9 of the can 4 and a section 9 of the can 4 facing flat end face 8 of the pump head 3, a ring seal 5 is disposed in a Stirnringnut 6 of the pump head 3.
- the pump head 3 has for this purpose an annular bead 7, on which the end face 8 is present and which serves to engage a clamping ring 10, on the other hand engages an annular bead 11 of the base housing 1.
- the clamping ring 10 is open at 12 on one side and by a screw which is tangentially inserted into an opening 13, shortened in its scope.
- the clamping ring 10 also has conically extending webs 14, so that a shortening of the circumference of the clamping ring 10 and by its engagement with the annular beads 7 and 11 of the pump head 3 and the base housing 1 leads to their clamping together.
- the pump head 3 receives a power rotor 15 with a permanent magnet 16 in a pot-shaped portion of the can 4, as well as a through the power rotor 15 with driven counter rotor 17 with the pivot bearing 18th
- Fig. 2 in particular, the clamping ring 10 is shown with its open side 12th
- the invention is not limited only to canned machines, but also detects rotary piston machines, in which the seal between the exchanged pump head and the base housing is effected by other known means. Decisive is the simple and practical interchangeability of the pump head with separation of the flow medium. All in the description, the following claims and the drawings illustrated features may be essential to the invention both individually and in any combination.
