Definitions

  • the present invention relates to a shower, especially dishwashing spray, according to the preamble of claim 1.
  • a shower of this type is, for example, from EP-A-0 656 503 known. It has a tubular handle which has a connection nipple at its inlet end for a supply hose and on its outlet side End carries a shower head and a shut-off valve. The The shut-off valve is against the force by means of a hand lever a return spring intended for closing can be actuated.
  • An inner tube extends within the handle from the connection nipple to the shut-off valve. This pipe is from surrounded and shows a rubber-elastic hose spaced openings into the interior of the hose. When closing the Shut-off valve creates a temporary overpressure due to the decelerated water column of the supplied water. To dampen this pressure surge in this serves the supply line with its disadvantageous consequences inner tube with the slipped hose, which is temporarily as a flexible wall in a cavity in the Extends the handle.
  • shut-off valve one Dishwashing spray, even if the Hand lever, delayed closing.
  • a cage is in the closing sense of the shut-off valve and with it operatively connected, spring-loaded valve piston guided, through which one acts as a choke Connection channel runs.
  • the connecting channel connects a cage chamber delimited by the cage and the valve piston with the one arranged inside the handle Cylinder tube limited flow channel for the water.
  • a flow channel Cylinder element arranged in which a gas volume to Damping the pressure surges. Since the cylinder element in its end area facing the shut-off device is open, the corresponding total flow cross section is available Damping the pressure surges is always available. Further this flow cross-section is close to the Shut-off valve, where the pressure surges when closing quickly be generated.
  • the cylinder element is also in the Inside the flow channel, which to prevent the rectilinear spread of the pressure surges and thus also to whose damping contributes.
  • the one shown in the figures, designed as a dishwashing shower shower has a handle 10 with a tubular Handle shell 12 on. Concentric to the grip shell 12 and a connecting sleeve 14 is arranged within the latter, the one with a connection nipple 16 and the other is screwed to a shower head element 18.
  • the connection nipple 16 has a thread on, which forms a connection means 20 for connection a hose is intended for the supply of water.
  • a shower screen 22 is used, which by means of a ring-like Sieve holder 24 is held and which peripheral is encompassed by a rubber-elastic protective ring 26.
  • the shower head element 18 with the shower screen 22, the screen holder 24 and protective ring 26 forms a shower head 28.
  • connection nipple 16 has a not shown in the figures, stop shoulder extending over part of the circumference on, which with this side of the end Handle shell 12 interacts.
  • the grip shell as can be seen in FIGS. 2 and 3, on their Inside one over part of the perimeter itself extending stop shoulder 32, which with a counter shoulder cooperates on the shower head element 18.
  • the grip shell 12 is held in the axial direction and secured against twisting by not having one has shown anti-rotation tongue, with a Interlocking surface on the connecting nipple 16 interacts.
  • a circumferential groove on the shower head element 18 is a O-ring 36 used, on which the handle 12 with its End area bears around the for thermal insulation purposes trained cavity 38 between the handle shell 12 and to seal the connecting sleeve 14.
  • the connecting sleeve 14 delimits a flow channel 40, through which the water from the connection nipple 16 to the shower head 18 is directed.
  • a cylinder element 42 Located in this flow channel 40 concentric to the connecting sleeve 14, a cylinder element 42, whose length measured in the axial direction approximately is half as long as the entire length of the dishwasher.
  • the cylinder element 42 is on the connection means side closed by means of a cylinder base 44, of which formed integrally with the cylinder element 42, a hollow cylindrical retaining flange 46 protrudes, which in a corresponding recess in the connecting nipple 16 engages.
  • the cylinder element 42 For concentric mounting of the cylinder element 42 further serve to protrude inwards from the connecting sleeve 14 Ribs that are about halfway in the axial direction Length of the cylinder element 42 extend.
  • the inside of the Holding flange 46 communicates on the one hand with the inlet opening 48 of the connecting nipple 16 and on the other hand radial passages 50 with the annular flow channel 40 between the connecting sleeve 14 and the cylinder element 42nd
  • a double-acting piston 52 is located in the cylinder element 42 freely movable in the axial direction. This means two sealing sleeves spaced apart in the axial direction 54 pistons sealingly guided on the cylinder element 42 52 delimits together with the cylinder element 42 Volume of gas 56, which is intended to dampen pressure surges is how to describe this below.
  • a cylinder cover sits on the free end of the cylinder element 42 58 - for example by means of a bayonet catch attached to the cylinder element 42 - which one has central passage 60. Through this central Through the passage 60, the piston 52 is on this side with the Pressurized water. On the other hand, it affects the Piston 52 the pressure in gas volume 56.
  • a return spring 62 is supported on the cylinder cover 58 for a shut-off valve 64 acting compression spring, on the other hand on the outside of a slide bottom 66 cup-shaped slide 68 rests.
  • the slider 68 is with its jacket 70 on, essentially hollow cylindrical shower head element 18 in the axial direction slidably guided.
  • a first quad ring 72 Arranged radially on the inside The circumferential groove of the shower head element 18 is a first quad ring 72 used, which with the jacket 70th cooperates to prevent water from flowing out of the flow channel 40 between the shower head element 18 and the To prevent slide 68 through.
  • the sealing element 76 attached to the slide 68 forms one Closure element of the shut-off valve 64, which with a formed at the free end of a valve seat member 82 annular valve seat 84 cooperates. That on the shower head element 18 fastened by means of a screw connection, at least approximately hollow cylindrical valve seat element 82 engages from the side facing away from the slide bottom 66 forth in the slide 68 and has a groove on the circumference in which a second quad ring 72 'is arranged. This lies on the inner wall of the jacket 70 of the slide 68 and prevents water from escaping from the Slider 68, the valve seat member 82 and the sealing element 76 limited space. This space is through radial flow openings 86 through the jacket 70 of the slide 68 connected to the flow channel 40.
  • FIG. 1 shows, this is otherwise rotationally symmetrical and shower head element 18 with a hollow cylindrical design two diametrically opposite through openings 88 provided, each of a fork element 90 one Hand lever 92 are reached.
  • the parallel to each other extending fork elements 90 are in their free end region by means of a bearing pin 94 on the shower head element 18 pivoted.
  • the fork elements reach through 90 - as can be seen in FIG. 1 - outside Driver recesses 96 on the jacket 70 of the slide 68. This creates an operative connection via the slide 68 between the hand lever 92 and that as a closure element serving sealing element 76 of the shutoff valve 64.
  • Shut-off valve 64 is, at least approximately on the outside of the grip shell 12 and can by means of a retaining ring 100 in this Position held against the action of the return spring 62 become.
  • the retaining ring 100 is limited on the connection nipple 16 rotatably mounted and has a radial recess 102 with an undercut 104. In the corresponding The free end area can be in the rotational position of the retaining ring 100 of the lever shaft 98 inserted into the radial recess 102 and by then turning the retaining ring 100 is the hand lever 92 against pivoting in the Undercut 104 held, as can be seen in FIG. 3 is.
  • a balloon or bellows 106 is indicated by dashed lines in FIG. 1, which is in the gas volume 56. It's a balloon or bellows 106 is present, this is preferably with a gas Air, filled and provides a reliable function the pressure shock absorption even when the Seal between piston 52 and cylinder element 42 damaged or should no longer be functional.
  • the mode of operation of the washing machine shown in the figures is as follows. With the shut-off valve closed 64 - as shown in FIGS. 1 and 2 - that stands Water in the flow channel 40 under a pressure that is static Pressure of the water supply corresponds.
  • the piston 52 is, as indicated by dashed lines in FIG. 2, in a position in which the gas in the gas volume 56 is compressed to a pressure which corresponds to the water pressure equivalent.
  • the hand lever 92 is used to interrupt the flow of water released, the shut-off valve 64 closes under the force the return spring 62 very quickly. This will make the water flow abruptly interrupted what as a result of braking the water column to generate a pressure surge leads.
  • This pressure surge is now dampened by the Piston 52 moves in the direction against the cylinder bottom 44.
  • the central passage 60 becomes as large as possible trained and this is close to the shut-off valve 64, an optimal damping effect is achieved. This is further supported by the fact that the piston 52 and Cylinder element 42 limited displacement designed as long as possible is.
  • the piston is used to further optimize the damping effect 52 formed as light as possible, for example by Production from plastic is made possible.
  • the one in the figures shown blind hole-like axial recesses Pistons 52 also contribute to weight reduction. moreover ensure the V-shaped cross-section Sealing sleeves 54 an easy moving the Piston 52 with a reliable seal.
