The direction of action of the torsion spring 42 is chosen so that the receiving space leg 39 against the step 34 of the absorbent active section 33 is charged.
  • the torsion spring 42 causes an opposite the displacement when the absorbent body swells 13 directed displacement of the loading element 26, with which the second valve leg 38 comes into effect. This also shifts the closure body via its nose 40 18 in a valve closure standby position. When the suction air flow is switched on the closure body 18 abruptly in the closed position relocated, with which no operation of the suction attachment is possible without an inserted absorbent body 13.
  • the receiving space leg closes 39 in the respective active position (Fig. 12 13) an acute setting angle alpha or Beta with the inner wall of the receiving space 10.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a suction device attachment, in which the Liquid collecting body F radially outside with respect to the Suction channel 5 is arranged.
  • a suction device attachment in which a Receiving space 10 for the liquid collecting body F is annular.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a suction device attachment, in which the Liquid collecting body F the receiving space 10 in the circumferential direction only partially filled.
  • suction device attachment in which the receiving space 10 on the upstream side a connection opening 12 to the suction channel 5.
  • Suction channel 5 forms a throughflow section 9, which of the receiving space 10 for the liquid collecting body F is surrounded.
  • suction device attachment in which the Connection opening 12 assigned to an inner surface 15 the suction channel wall is formed.
  • Subject of the invention is also a suction device attachment, in which in the Receiving space 10 for the liquid collecting body F in Longitudinal direction of the receiving space 10 extending transport routes are designed for the liquid.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a suction device attachment, in which the Transport routes essentially as axial, in the inner surface of the outer wall 31 of the receiving space 10 grooves formed for the liquid collecting body F. 32 are formed.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a suction device attachment, in which the Receiving space leg 39 has a bevel 43, to guide the absorbent body 13 between the receiving space leg 39 and an inner wall of the receiving space 10 when the absorbent body 13 is inserted.
  • a suction device attachment in which the Recording space leg 39 in the operative position of the first Valve leg 37 with an inner wall of the receiving space 10 a first acute setting angle (alpha) includes.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a suction device attachment, in which the second loading element 26 rotatable in the end region of the receiving space 10 is stored.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a liquid collecting body in which the absorbent body 13 in the course of absorbing liquid an essentially axially directed expansion takes place.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a liquid collecting body in which the absorbent body 13 in the course of absorbing liquid an essentially radially directed expansion takes place.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a liquid collecting body in which the absorbent body 13 from substantially perpendicular to its direction of expansion, individual Layers 14 exists.
  • Subject of the invention alone or in combination with the previously explained objects of importance is also a liquid collecting body in which the layers 14 are wrinkled together.
