Definitions

  • the invention relates to a multi-way valve, in the housing of which a mixing chamber is formed, in each of which an inlet bore for cold water and for hot water opens and emanate from the outlet connection, of which either one of two coaxially arranged via one externally displaceable by means of an eccentric Double piston is lockable.
  • the invention has for its object to improve multi-way valves of the type mentioned in the function and also in the sealing effect, and to design it so that they are easy to install and their wear parts can be replaced.
  • this object is achieved in that a control housing is inserted in the valve housing, which has a bore for the double piston coaxial with two outlet ports, which bores are sealed off from the outlet ports by means of a lip seal which interacts with one half of the double piston, otherwise is provided with passages to the mixing room.
  • control housing that is to say with the double piston and lip seals installed.
  • the multi-way valve is ready for use.
  • the control housing can be removed from the
  • Valve housing can be removed. Its wear parts - lip seal, O-rings, also the piston and the control housing itself - can be exchanged and the multi-way valve can then be made ready for operation again.
  • the lip seals which are in contact with the inlet surfaces of the outlet nozzle and are held in the control housing, interact with the double piston: When the double piston approaches one of the lip seals, at the end of the start-up movement, the lip seal lies on the end face of the double piston, especially on the Edge of the end face, and thus flexibly seals the outlet connection to be closed.
  • An exemplary embodiment of the invention is shown in the drawing and is described in detail below. Enlarged on a scale of around 1.5: 1:
  • 1 shows a vertical section through a four-way valve along the section line C-D in FIG. 2; 2 shows a horizontal section through the four-way valve along the section line A-B in FIG. 1.
  • the four-way valve selected as an exemplary embodiment has a valve housing 1.
  • a control housing 3 is inserted into the valve housing 1.
  • a double piston 4 is mounted axially displaceably in the control housing 3.
  • a lip seal 2 is provided between the control housing 3 and the valve housing 1 in the area of each end face of the double piston 4.
  • the control housing 3 is held in the valve housing 1 by means of a sealing cover 5.
  • Sealing cover 5 is penetrated by an eccentric 6, by means of which the double piston 4 can be moved.
  • an adapter 7 is placed on the sealing cap 5.
  • a threaded sleeve (not shown) for height adjustment of the four-way valve can be screwed into the adapter 7.
  • the adapter 7 is penetrated by an extension spindle 8, which is connected to the eccentric 6.
  • Adapter 7 and extension spindle 8 allow the one hand
  • the valve housing 1 is designed in the manner of a hollow cylinder. Its bottom 11 is closed. In its wall 12 there is an inlet bore 13 for cold water, diametrically opposite an inlet bore 14 for hot water. Between the inlet bores 13, 14, also diametrically opposite, an outlet connection 15 for connection to a bath outlet and an outlet connection 16 for connection to a shower are screwed. One of the lip seals 2 rests on the input surfaces of the outlet connections 15, 16. The open ceiling of the hollow cylinder is closed by the cover 5. A centering pin 17 is introduced into the base 11, with the aid of which the control housing 3 is inserted into the valve housing 1 in the correct position.
  • a mixing chamber 18 is formed in the valve housing 1 between the base 11, the wall 12 and the sealing cover 5.
  • the inlet bore 13 for cold water and the inlet bore 14 for hot water open into the mixing chamber 18.
  • the outlet connection 15 for the bath outlet and the outlet connection 16 for the shower start from the mixing chamber 18.
  • One of the two outlet connections 15, 16 can optionally be closed by means of the double piston 4.
  • the control housing 3 consists of a circular cover 31 and a block-shaped guide part 32 for the double piston 4 formed on the cover 31.
  • the cover 31 has a central bore 33 for the passage and a profiled opening 30 as a stop for the eccentric 6. Eccentric to the bore 33, two threaded bores 34 are let into the cover 31 for receiving a mounting screw (not shown).
  • An O-ring 93 is inserted into the edge of the cover 31 and seals the cover with respect to the valve housing 1.
  • slots 36 are made in the block-shaped guide part 32 parallel to the outlet connections 15, 16 adjacent walls 35, which establish the connection with the mixing chamber of the valve housing 1.
  • a notch 37 is arranged in the axial direction of the double piston 4 for receiving the centering pin 17.
  • the block-shaped guide part 32 is provided coaxially with the outlet connections 15, 16 with a bore 38 in which the double piston 4 is guided.
  • the bore 38 has a shoulder 39, against which one of the lip seals 2 rests in the relaxed state.
  • the double piston 4 is formed in its central part as a cylinder 41.
  • An annular space 42 for the attack of the eccentric 6 is recessed in the cylinder 41.
  • an annular groove is provided on both sides for receiving one of two O-rings 94, which seal the double piston 4 from the control housing 3.
  • a cylinder 43 of smaller diameter than the cylinder 41 connects to each end face of the cylinder 41.
  • Each of the cylinders 43 merges on the free end face into a flow surface 44 projecting in the central axis.
  • the edge of the flow surface 44 is provided with a flat ring surface 45 for the contact of the lip seal 2 in the compressed state.
  • the control housing 3 and the eccentric 6 are held by the cover 5.
  • the closure cover 5 has an external thread 51 with which it is screwed into the valve housing 1. With the inner surface, the closure cover 5 rests on the cover 31 of the control housing 3. On the outside, the closure cover 5 is continued in a cylindrical collar 52 which is arranged coaxially with a bore 53 contained in the closure cover 5. The collar 52 and the bore 53 are penetrated by the eccentric 6. An inner flange 54 projects into the bore 53 and supports the eccentric 6. Sliding disks 90 are arranged on both sides of the inner flange 54 and between the sealing cover 5 and the cover 31 of the control housing 3.
  • the eccentric 6 is designed as a cylinder 61.
  • An annular groove for receiving an O-ring 96 is provided in the cylinder 61, which serves to seal against the cover 31 of the control housing 3.
  • On the end facing the double piston 4 is on the
  • Cylinder 61 an eccentric pin 62 is formed, which engages in the annular space 42 of the double piston 4.
  • the eccentric 6 has a polygonal head 63, via which a spindle of the corresponding country or company standard for rotating the eccentric 6 can be inserted.
  • Formed between the cylinder 61 and the polygonal head 63 are a collar 64 of larger diameter, which bears against the inner annular surface of the inner flange 54, and a collar 65 of smaller diameter, which bears against the cylinder surface of the inner flange 54.
  • an adapter 7 is screwed to the closure cover 5 and receives an extension spindle 8 placed on the polygonal head 63.
  • Eccentric 6 leads, for example, to a position in the direction of the outlet connection 15 until the ring surface 45 of the associated flow surface 44 bears against the lip seal 2 and the eccentric pin 62 bears against the profiled opening 30 in the cover 31 - shown in the drawing on the right -. This closes the access of the outlet nozzle 15 to the mixing chamber 18.
  • the opposite flow surface 44 of the double piston 4 is arranged at a distance from the associated lip seal 2, which in this case, in the expanded state, on the one hand on the end face of the assigned outlet nozzle 16 and on the other the shoulder 39 of the control housing 3 rests - shown in the drawing on the left -. From the mixing chamber 18 is in the 36 via the slots
  • Control housing 3 free access to the outlet nozzle 16 for the shower.
