  • an energy accumulator for example a coil spring
  • At least one displacement device of variable volume is arranged in the metering chamber and is connected to the line.
  • this displacement device should be designed as a dense balloon or be provided with a dense balloon, the interior of which is connected to a branch line of the line.
  • a device for temporarily interrupting the flow in a pipeline should preferably be provided at its entrance, with a closure body arranged between an inlet end and an outlet end, which can be guided by the flow pressure against an energy accumulator, for example a coil spring, and interrupts the flow path depending on the pressure.
  • an energy accumulator for example a coil spring
  • the tubular body together with the displacer forms a structural unit with the upstream device and a branch line from which the water pipe connecting the device with a connecting piece as the input of the device (60) is led to an inlet device for the displacing device .
  • the upstream device of the structural unit has a cylinder connecting the inlet end and outlet end with lateral longitudinal recesses, which are arranged downstream in the flow direction of the closure body designed as a drum-like and hollow piston body, the latter being provided with openings on its circumference and connected to a hollow shaft pointing in the flow direction.
  • the inlet and outlet ends are connected by a cylinder with an internal annular or partial annular groove arranged on the inlet side and lateral longitudinal recesses arranged downstream in the direction of flow, near the annular or partial annular groove, the closure body, which is designed as a drum-like hollow piston body provided with openings on its circumference, as well as an in Direction of flow pointing to the longitudinal recessed hollow shaft is connected. It has proven to be advantageous to provide at least one sealing ring or the like encompassing the hollow shaft on both sides of the longitudinal recesses and the energy accumulator or the like between the inlet-side sealing ring or the like. and to arrange the longitudinal recesses.

  • a tube space can extend from a narrow tube space part which is delimited against the longitudinal recesses by an annular rib and accommodates the energy accumulator, and a further tube space part adjoining the direction of flow with the formation of a stop; this stop should be arranged in the path of movement of an Simmerring on the inlet side, against which the helical spring serving as an energy store is supported.
  • An inlet channel is separated from the tubular space part of larger diameter by that ring or partial ring groove, in which at least one ring-shaped sealing lip or an O-ring is provided near the ring groove; when the piston body moves against the direction of flow, i.e. in too At least partially relaxed position of the energy accumulator, this sealing lip surrounds the piston body, the hollow shaft being at a distance from the longitudinal recesses - at least from their end near the drain.
  • the piston body is bounded against the direction of flow by a closed end face, which is opposed on the other side of the piston body by a counter surface perforated by the hollow shaft.
  • the outer surface of the piston body tapers conically between its openings on the one hand and the counter surface, as a result of which the seat of the sealing lip becomes increasingly tighter when the piston body is displaced against the direction of flow.
  • This conical outer surface preferably ends in the direction of flow at an annular rib of the piston body.
  • the named coil spring stretches between the mating surface or an adjacent sealing ring or the like. and the ring rib of the cylinder.
  • the result is a simple pipe separator with a coil spring that is always outside the water-carrying rooms and reliable separation.
  • a pipe piece with circumferential slots is provided between the cylinder and the piston body, which form the flow path with its openings when the piston body is in a radially opaque position. If the water pressure is so strong that the piston body has guided the piston body between the circumferential slots against the force of the energy accumulator surrounding that hollow shaft, the water can find its way through these and the openings into the hollow shaft, through which it then flows.
  • the hollow shaft extends through the cylinder zone with the longitudinal recesses and seals the flow path against it.
  • the displacement device is designed according to the invention as a dense bellows or provided with a dense bellows, the interior of which is connected to the branch line of the line. It is an extremely robust and easy-to-use design of the displacer.

  • a spout designed as a tube is particularly suitable for this purpose, at the mouth of which a seat is provided for a locking pin; the axial displacement of this locking pin allows the inflow regulation in a simple manner.
  • the mouth of the tube is arranged at the inlet of a metering hose protruding into the line.
  • a device according to the features of claims 7 to 12 has proven to be particularly favorable; The regulation of the discharge from the dosing room is made possible with parts that are easy to manufacture.
  • a device 10 for installation in a shower device which is not shown for reasons of clarity, carries an inlet connection 12 on a mounting plate 11, the connection end of which is located behind the mounting plate 11 and can be connected to a water pipe.
  • This inlet connector 12 is designed as a T-piece, the mouth facing in the direction of view is closed by a nut 13 with a sieve 14.
  • the arm 16 of the inlet connector 12 directed parallel to the plate surface 15 is connected by means of a nut 17 to the inlet end 18 of a pipe separator 20, the outlet end 19 of which merges into a water pipe 21 in the region of a further nut 17.
  • This pipe separator 20 serves to temporarily interrupt the water flow and has a cylinder part 22 in which axially parallel elongated holes 23 can be seen are to which an annular rib 24 connects at the end of the elongated hole.
  • the latter offers an annular shoulder 25 against the flow direction x, which delimits a tube space 26.
  • a tubular space cutout 27 closes a larger diameter d 1 than the diameter d of the tubular space 26, forming a stop shoulder 28 on which a sealing ring 29 is seated.
  • This larger-diameter tube space section 27 is delimited on the inlet side by an annular groove 30, after which the tube space continues as the inlet channel 31.

  • the cylindrical circumferential surface 36 merges in the flow direction x into a tube piece 38 with a conically tapering outside 39. The latter ends at an annular outer rib 40, which on the other hand creates an annular surface 41.
  • a helical spring 44 can be seen on a hollow shaft 43 of the piston body 34. If water now flows with a slightly higher pressure than the spring force in the flow direction x through the inlet channel 31 against the end face 35, the piston body 34 is carried until its openings 37 rest in the annular groove 30. In this case, the piston skirt 43 extends to a sealing ring 45 and thus spans the elongated holes 23 of the cylinder part 22: the flow space between the inlet connector 12 and the water pipe 21 is established.
  • the water pipe 21 ends in a connecting piece 47, the socket on the back 48 of the plate is designated 49.
