Abstract

A sanitary fitting ( 100 ) including a fitting housing ( 102 ) having a housing interior ( 103 ) into which a cartridge ( 106 ) or a cartridge adapter having a cartridge provided in a cartridge receptacle ( 105 ) is inserted, which cartridge has at least one inlet opening connected to at least one outlet opening of the cartridge ( 106 ) to conduct fluid through the cartridge ( 106 ). The fitting includes—at least one hose line ( 108 ) for supplying the fluid to the cartridge ( 106 ), which hose line has, at least at the end close to the cartridge, a hose connection element ( 109 ). The hose connection element ( 109 ) is securely held in a retaining position on the cartridge ( 106 ) or on the cartridge adapter, to prevent removal, and the free end of this element that encircles a hose opening ( 111 ) lies against the edge region of the cartridge ( 106 ) that encircles the associated inlet opening.

3. The sanitary fitting ( 100 , 101 , 601 ) as claimed in claim 1 , wherein the hose connection element ( 109 ) and an adjacent one of the at least one inflow opening of the cartridge ( 106 ) are sealed off at least one of radially or axially by a ring seal ( 117 ).

4. The sanitary fitting ( 601 ) as claimed in claim 1 , wherein the passage opening ( 110 ) is assigned a hose-connection-element receptacle ( 114 ) which has a receiving bevel ( 619 ) in a form of a spherical cap adapted to receive the hose connection element ( 609 ).

5. The sanitary fitting ( 100 , 101 , 601 ) as claimed in claim 1 , wherein the hose connection element ( 109 , 609 ) and an adjacent one of the at least one inflow opening of the cartridge ( 106 ) are sealed off by a ring seal ( 117 , 617 ).

6. The sanitary fitting ( 101 ) as claimed in claim 5 , wherein the ring seal ( 117 ) passes regionally into a hose-connection-element receptacle ( 114 ) such that the ring seal ( 117 ) is secured in the hose-connection-element receptacle ( 114 ).

7. The sanitary fitting ( 100 , 101 ) as claimed in claim 1 , further comprising:
a passage opening ( 110 ) in the cartridge adapter ( 104 , 604 ) or in the cartridge ( 106 ),
a plug-in slot ( 112 ) opens into the passage opening ( 110 ), said plug-in slot ( 112 ) being formed to open transversely toward a longitudinal axis of the cartridge adapter ( 104 , 604 ) or of the cartridge ( 106 ) at a plug-in opening ( 113 ),
the passage opening ( 110 ) is assigned a hose-connection-element receptacle ( 114 ) which has a receiving shoulder ( 115 ) or a receiving bevel ( 619 ), wherein the receiving shoulder ( 115 ) borders the passage opening ( 110 ), and
the at least one hose line ( 108 ) assigned to the passage opening ( 110 ) is introducible into the passage opening ( 110 ) through the plug-in opening ( 113 ) via the plug-in slot ( 112 ) such that the hose connection element ( 109 ) bears on the receiving shoulder ( 115 ) or on the receiving bevel ( 619 ) in a secured manner via a cross-sectional expansion to prevent the at least one hose line from being pulled off.

8. The sanitary fitting ( 100 , 101 ) as claimed in claim 7 , wherein the cross-sectional expansion is formed on the hose connection element ( 109 ) as an annular shoulder or as an annular flange ( 116 ).

9. The sanitary fitting ( 100 , 101 ) as claimed in claim 8 , wherein the annular shoulder or the annular flange ( 116 ) is dimensionally adapted with an outer contour thereof to a cross section of the hose-connection-element receptacle ( 114 ).
