For a simply constructed pivot and swivel joint securing a sealing of the control element for the connection of a support arm to a control element, it is provided that the pivot and swivel joint ( 3 ) is implemented having a rotary sleeve ( 10 ) including an axially continuous recess ( 41 ) and having a swivel sleeve ( 11 ) connected thereto via a swivel axis (S) including an axially continuous recess ( 42 ), which is swivelable relative to the rotary sleeve ( 10 ) about the swivel axis (S), a rotary axis (D) being configured at the axial end of the rotary sleeve ( 10 ) facing away from the swivel axis (S), and a sealing hose ( 30 ) being disposed between the rotary sleeve ( 10 ) and the swivel sleeve ( 11 ), which by a first axial end sealingly abuts at the recess ( 41 ) of the rotary sleeve ( 10 ) and by the opposite second axial end is sealingly disposed at the axial end of the swivel sleeve ( 11 ).
1. A pivot and swivel joint comprising:
a rotary sleeve comprising a recess, a first end, and a second end opposite the first end;
said rotary sleeve having a center axis that defines a rotary axis (D) of the rotary sleeve;
a swivel sleeve comprising a recess, a first end, and a second end opposite the first end;
said swivel sleeve being movably connected to the rotary sleeve so as to swivel, relative to the rotary sleeve, about a swivel axis (S);
a sealing hose disposed between the rotary sleeve and the swivel sleeve; and
said sealing hose comprising:
a first axial end that sealingly abuts at the recess of the rotary sleeve; and
a second axial end that sealingly engages with the second end of the swivel sleeve,
wherein the first axial end of the sealing hose comprises a sealing flange that axially abuts at a seal shoulder located inside the rotary sleeve.
2. The pivot and swivel joint as recited in claim 1 , further comprising a pressure disk configured to press the sealing flange against the seal shoulder.
3. A pivot and swivel joint comprising:
a rotary sleeve comprising a recess, a first end, and a second end opposite the first end;
said rotary sleeve having a center axis that defines a rotary axis (D) of the rotary sleeve;
a swivel sleeve comprising a recess, a first end, and a second end opposite the first end;
said swivel sleeve being movably connected to the rotary sleeve so as to swivel, relative to the rotary sleeve, about a swivel axis (S);
a sealing hose disposed between the rotary sleeve and the swivel sleeve; and
said sealing hose comprising:
a first axial end that sealingly abuts at the recess of the rotary sleeve; and
a second axial end that sealingly engages with the second end of the swivel sleeve,
wherein the second axial end of the sealing hose comprises a sealing flange that axially abuts an axial end face of the swivel sleeve.
4. The pivot and swivel joint as recited in claim 3 , wherein the sealing flange of the second axial end is disposed inside an axial indentation in the axial end face of the swivel sleeve.
5. The pivot and swivel joint as recited in claim 4 , wherein the sealing flange of the second axial end protrudes from the axial end face of the swivel sleeve.
6. A pivot and swivel joint comprising:
a rotary sleeve comprising a recess, a first end, and a second end opposite the first end;
said rotary sleeve having a center axis that defines a rotary axis (D) of the rotary sleeve;
a swivel sleeve comprising a recess, a first end, and a second end opposite the first end;
said swivel sleeve being movably connected to the rotary sleeve so as to swivel, relative to the rotary sleeve, about a swivel axis (S);
a sealing hose disposed between the rotary sleeve and the swivel sleeve; and
said sealing hose comprising:
a first axial end that sealingly abuts at the recess of the rotary sleeve; and
a second axial end that sealingly engages with the second end of the swivel sleeve; and
further comprising:
a housing ring coupled to the rotary sleeve; and
a support arm ring rotatably disposed between the housing ring and a stop located inside the rotary sleeve.
7. A pivot and swivel joint comprising:
a first sleeve comprising a main opening, a first end, and a second end opposite the first end;
said first sleeve having a center axis that defines a rotary axis (D) of the first sleeve;
a second sleeve comprising a main opening, a first end, and a second end opposite the first end;
said first end of the second sleeve being movably connected to the first end of the first sleeve, whereby the second sleeve can swivel relative to the first sleeve about a swivel axis (S);
a sealing hose comprising:
a portion disposed in an area of the swivel axis (S);
a first axial end that extends inside the first end of the first sleeve and sealingly engages with a surface of the first sleeve; and
a second axial end that extends inside the first end of the second sleeve and sealingly engages with a surface of the second end of the second sleeve,
wherein the first axial end of the sealing hose comprises a sealing flange that axially abuts at a seal shoulder located inside the first sleeve.
8. The pivot and swivel joint as recited in claim 7 , wherein the second axial end of the sealing hose comprises a sealing flange that axially abuts at a surface located inside the second axial end of the second sleeve.
9. A pivot and swivel joint comprising:
a first sleeve comprising a main opening, a first end, and a second end opposite the first end;
said first sleeve having a center axis that defines a rotary axis (D) of the first sleeve;
a second sleeve comprising a main opening, a first end, and a second end opposite the first end;
said first end of the second sleeve being movably connected to the first end of the first sleeve, whereby the second sleeve can swivel relative to the first sleeve about a swivel axis (S);
a sealing hose comprising:
a first axial end that extends inside the first end of the first sleeve and sealingly engages with an annular inner surface of the first sleeve;
a second axial end that extends inside the first end of the second sleeve and sealingly engages with an annular surface of the second end of the second sleeve; and
a portion that intersects the swivel axis (S) and is disposed between the first and second axial ends,
wherein the first axial end of the sealing hose comprises a sealing flange that axially abuts at a seal shoulder located inside the first sleeve.
10. The pivot and swivel joint as recited in claim 9 , wherein the second axial end of the sealing hose comprises a sealing flange that axially abuts at a surface located inside the second axial end of the second sleeve.
