1. A system including a diaphragm and co-acting part, comprising: a co-acting part which comprises a stiff outer wall, a first annular protrusion, and a second annular protrusion, wherein the stiff outer wall comprises a generally radially extending portion of the co-acting part having radial protrusions extending therefrom and including the outermost annular wall; anda diaphragm co-acting therewith which comprises a flexible wall of a predetermined shape and thickness, wherein the flexible wall of the diaphragm is movable along the stiff outer wall of the co-acting part, and wherein the diaphragm comprises at least two separately deformable flexible wall parts, wherein a first deformable flexible wall part is sized and configured to co-act with the first annular protrusion and a second deformable flexible wall part is sized and configured to co-act with the second annular protrusion. 2. The system of claim 1, characterized in that the deformable flexible wall parts of the diaphragm each unroll over the stiff outer wall part of the co-acting part. 3. The system of claim 2, wherein the stiff outer wall part of the co-acting part that co-acts with the deformable wall part of the diaphragm is formed by the radial protrusion. 4. The system of claim 3, characterized in that the deformable wall part of the diaphragm comprises an oblique wall part, wherein the oblique wall part co-acts with the radial protrusion of the co-acting part. 5. The system of claim 4, characterized in that the diaphragm has a substantially conical form. 6. The system of claim 1, further comprising a valve part. 7. The system of claim 6, characterized in that the valve part is accommodated in an opening in the diaphragm and in an opening in the co-acting part, wherein both openings form a flow channel for fluid. 8. The system of claim 7, wherein the valve part comprises a hook which co-acts with a protrusion in the flow channel in the co-acting part. 9. A pump comprising the system of claim 1. 10. A diaphragm for interacting with a co-acting part that has protrusions, the diaphragm comprising a flexible wall of predetermined shape and thickness; at least two separately deformable flexible wall parts, wherein a first deformable flexible wall part is sized and configured to co-act with a first annular protrusion of co-acting part and a second deformable flexible wall part is sized and configured to co-act with a second annular protrusion of the co-acting part;substantially vertical parts which unroll during functioning of the diaphragm; andat least two support edges formed by substantially horizontal parts against which the first and second annular protrusions of the co-acting part will support during operation.
