Definitions

• the invention relates to a medium forwarding unit with a circulating blade for transporting gaseous mediums, which contains a medium forwarding space, a house encasing the internal space accommodating an inlet and outlet communicating with the medium forwarding space, push elements for the forced circulation of the medium between the inlet and the outlet and a forwarding body carrying these push elements, and a regulating body allocated to the forwarding body via a movement coordinating part-unit, where the regulating body has- locking pieces extending into the internal space of the house, and the forwarding body and the regulating body are inserted in the house in a removable way, there are at least two push elements on the same forwarding body, the push elements are identical to each other, and the space part covered by the push elements has the ring shape of a body of rotation, and the push elements have a geometrical shape suiting the cross-sectional size and shape of the medium forwarding space, filling the cross-section of the medium forwarding space.
• the disadvantage of the solution is that due to its operation, during the movement of the pistons - as shown in figure 3 attached to the specification - the two cylindrical ring shaped volumes and the intermediate working space are linked together for a certain period, i.e. a completely free figure eight shaped working space is created.
• the significant disadvantage of the construction is that it is not suitable for the continuous realisation of permanent-volume medium transportation.
• our aim was to eliminate the deficiencies of the known medium forwarding units with a circulating blade and to create a version, which has a simple structural construction and is still suitable for the efficient transportation of gaseous mediums besides a minimal loss during forwarding, so that the manufacturing costs of the equipment remain at a favourable level and the costs incurred during operation also remain acceptable.
• the construction according to the invention is based on the recognition that if the shape of the passage for forwarding the transported medium and the shape and tracing of the path locking pieces suitable for the periodical opening and closing of this passage is constructed in the house in a way other than the ordinary, and the gaseous medium transported by the push elements is allowed to get behind the push element from its position in front of the push element in certain parts of the medium forwarding space, then with the device construction in this way even gaseous mediums can be transported efficiently, with a small loss during forwarding, and so the task can be solved.

• one of the crossing points is situated along the same section of the medium forwarding space between the inlet port and the outlet port, and a passage facilitating flow is cut into the delimiting surface of the medium forwarding space in the environment of the crossing point situated after the inlet port following the moving direction of the push elements.
• the medium forwarding unit with a circulating blade it may be favourable that there are at least two locking pieces arranged on the same regulating body, and that the number of the push elements situated on the same forwarding body is the same as the number of locking pieces arranged on the same regulating body.

• the medium forwarding unit according to the invention has numerous favourable characteristics. The most important one of these is that even in the case of gaseous mediums continuous and efficient medium transportation can be realised with a low loss during forwarding, both at a low and high regulation number. Moreover, due to the specific construction, in the case of a gaseous medium, besides transportation the unit can also be used for compressing the medium on the part of the medium near the outlet port, which, due to the novel construction practically results in an extended field of use.
• the medium forwarding unit according to the invention can also be used in the case of the transportation of a low amount of gaseous medium forwarded at a low revolution number.
• a further advantage is that due to the shape and arrangement of the forwarding body and the push elements, and the regulating body and the locking pieces, the rotating moving elements do not burden the moving axles, which results in significantly less abrasion and wear due to friction, so the lifetime of the medium forwarding unit is longer and there is a lower probability of failure.

• the pressure of the transported medium remaining in the section of the medium forwarding space 23 between the push element 32 and the locking piece, which is still keeping the crossing point 26 closed increases.
• no transported medium is flowing out through the outlet port 22 from the medium forwarding space 23 of the internal space 20 as it has been closed by the push element 32, but the push element 32 gets next to the by-pass gap 27 situated near and before the crossing point 26.
• 6 b shows the position when the push element 32 leaves the outlet port 22 making it possible for the transported gaseous medium locked in between the push element 32 and the push element 31 to flow out through the outlet port 22 from the part of the medium forwarding unit 23 between the push element 32 and the push element 31.
• the push element 32 has left the by-pass gap 27 situated near the outlet port 22 and closed it again, preventing by this the transported medium from flowing back behind the push element 32 from the space part between the crossing point 26 and the crossing point 25.
