  • DE 29516157 U1 discloses a sanitary fitting for detachable securing to a fixed body part.
  • the body part is equipped with two one-way valves, one for hot water and one for cold water.
  • Each one-way valve holds a ball which, due to water pressure, is pressed upwards and blocks the outflow passage.
  • the sanitary fitting is installed the balls are pressed downwards and thus they open for the water flow.
  • the sanitary fitting is inexpedient in many ways.
  • the object of the invention is therefore to provide a releasable faucet or fitting, which is significantly more reliable than hitherto known and which do not cause an unnecessary drop in pressure.
  • a faucet of the above type is characterised by being equipped with at least one release member for activation of the one-way valve.
  • the release member is downwardly pointed and includes preferably a plurality of relatively large openings. As a result, turbulent flows are avoided, which might otherwise cause a drop in pressure.
  • a fixed ceramic washer can be fitted to the cartridge body, said fixed ceramic washer has two oblong circular openings on top as well as a possible additional opening for feeding back mixed water.
  • a pivotal and shiftable ceramic washer can be fitted to the top of the fixed ceramic washer, said pivotal and shiftable ceramic washer performs the function of temperature control and volume control respectively.
  • the pivotal and shiftable ceramic valve may have a keyhole- shaped opening, a shifting of said ceramic valve providing the function of volume con- trol and a pivoting providing the function of temperature control.
  • Fig. 1 shows a faucet to be releasably secured in a fixedly mounted base body part in a tabletop.
  • Fig. 2 shows the body part including a one-way valve, which is activated at the moment the faucet is mounted in said body parts.
  • Fig. 3 shows the faucet after mounting in the base body part.
  • Fig. 4 shows a release member secured to the faucet, said release member releasing the one-valve at the moment the faucet is mounted in the body part.
  • Fig. 5 shows a body part for mounting of a mixing faucet allowing a feeding of both hot and cold water.

  • a one-way valve 7 is built-in in this base body part 6, which substantially is circular and includes circular through-going opening in the middle.
  • the faucet is secured to the base body part by means of a clamping screw placed in the side of the faucet.
  • the release member 4 is downwardly pointed and includes a plurality of relatively large through-going openings 4a serving to ensure the best possible flow without turbulence, since turbulence might otherwise cause an undesirable drop in pressure in the faucet.
  • a particularly advantageous embodiment includes four openings, which extend substantially axially. Each opening has a diameter of approx. five mm. As a result the best possible flow is achieved and at the same time flow is as laminar as possible.
  • a rubber packing ring is placed in the circumferential groove 4b, cf. Fig. 4, in order to avoid an undesired outflow of water during the mounting/demounting of a faucet at the moment the one-way valve is opened or at demounting before the one-way valve is closed, but before the mounting of the faucet is completed or at demounting before the one-way valve is closed.
  • the release member is preferably shaped such that it can be screwed upwards into the body part of the faucet. Then a gripping means allows the through-going openings 4a to be utilized such that they carry out the screwing movement for screwing in the release member 4.
