Definitions

  • the present invention relates to a connection device at an inlet to a valve, particularly a blender valve, from a member connected to a water supply system, said connection device comprising at least one housing.
  • BACKGROUND AND PROBLEM Current blender fittings comprise a valve unit which is normally manufactured in a ceramic material, the task of which is to blend incoming cold and warm water. This valve unit is connected to a connection or other connection means that are, in turn, connectable to pipes in a water supply system.
  • connection devices Upon connection between a valve unit and for example a connection pipe, various types of connection devices are currently used, the function of which is to form a sealed, solder-free and swiveling connection between the connection pipes and the valve unit, said valve unit normally being housed in the upper portion of the blender housing.
  • connection means for example distributors in shower blender fittings
  • similar types of connection devices are used in order to achieve a sealed connection.
  • connection devices shall also ensure that the water passage formed through the same, will not give rise to unnecessary turbulence in the water, but will rather provide a smooth transition between the connection pipes and the valve unit. Turbulence usually arises when water flows through passages with many varying diameters and turbulence may result in noise and pressure shocks that tend to spread to the pipes and result in a disturbing, so called base sound in buildings.
  • connection device for a valve unit in a blender fitting for example a wash basin, according to the above description, is for example known from the document SE-B-460 553.
  • the connection pipes are mounted in a solder-free and swiveling way, since they are provided which a widened end portion which may be joumalled between a connection piece in the device and a seat in the blender housing.
  • the seats are positioned far into the blender housing, in the direct vicinity of the ceramic valve unit which is mounted in the blender housing, which means that the pipes extend up to a spacer portion between two partition walls in the blender housing.
  • a drawback with the use of this connection device is that the blender housing must be provided with several internal partition walls that must be molded in connection with the molding of the blender housing.
  • connection device which has a similar connection of the connection pipes, but wherein the device comprises a passage element with at least one connection piece forming a connection for a pipe, which pipe in turn is connectable to a water supply system.
  • the connection piece is provided with a pipe portion which is arranged coaxially with the pipe and adapted to the extend a distance into the pipe.
  • the function of the pipe portion is to form a gap between the pipe and the portion, said gap being intended to help dampening noise.
  • this device comprises two transverse walls sealingly cooperating with two collar portions within the blender housing.
  • the blender housing is also provided with a further collar portion being arranged to support the connection piece. The partition walls needed in the blender housing, have thus been reduced to only being collar portions.
  • connection devices are thus associated with a number of problems, and the object of the present invention is therefore to eliminate these problems and to provide a connection device, which:
  • connection device comprising a housing, wherein the housing is provided at least one passage, which at least partially houses a sealing member and a support member, wherein the sealing member is supported by the support member, and the sealing member is adapted to cooperate with a hole periphery in the member connection to a water supply system, and wherein the sealing member is provided with an internal chamfer, which is adapted, by means of a pressure generated by the water, to press against the hole periphery and to seal against it.

  • connection device according to the invention will be described with reference to a number of preferred embodiments. In the various examples, it is not the connection device as such which has been altered, but rather its surrounding, i.e. the various types of applications wherein the device may preferably be used. It should, however, be noted that the configuration according to the invention is not limited to the one shown in the examples, but that a number other configurations are of course conceivable.
  • connection device As an introduction, with reference primarily to Fig. la-d, Fig. 2a-c and 6 (but also to the other drawings), the parts included in the connection device will be briefly described. Then, with reference primarily to Fig. 3-5, the connection device according to the first embodiment will be described in conjunction with a so called single-lever blender, which is connected to pipes for warm and cold water, and wherein the member connected to the water supply system is a connection pipe. Furthermore, with reference primarily to Fig. 7-8, the connection device according to a second embodiment will also be described in conjunction with a single-lever blender, but in this case the member connected to the water supply system is a machined hole in a turned blender housing. Finally, with reference primarily to Fig. 9-11, a third embodiment of the invention will be described in conjunction with a shower blender, where the connection member is a machined hole in the shower blender housing.
  • connection device which is here in its entirety denoted 10, includes at least one housing which may be configured in many different way depending on the application at hand. Examples of housings will be described in more detail below, for the various embodiments, and in the drawings the various housings are referred to as 12a, 12b and 12c respectively.
  • the housings 12a-c have, however, one thing in common, namely that they are provided with at least one passage being directly or indirectly connected to the water supply system. In each embodiment, a passage is shown, which is referred to in the drawings as 14a, 14b and 14c respectively.
  • the passage 14a-c preferably has a substantially circular cross-section and is shaped to house at least one sealing member, which is the same in all embodiments and has the reference numeral 16, and a support member, which in the same way has been given the reference numeral 18, it being provided, in its inner peripheral surface, with a rim (which will be described later) against which the support member 18 and the sealing member 16 may abut and be supported by.
  • the sealing member 16 is adapted to be supported by the support member 18 by means of the sealing member 16 and the support member 18 each being provided with a through-hole 20 and 22, respectively, and that the support member 18 is adapted to entirely or partially be inserted into the hole 20 in the sealing member 16.
  • the sealing member 16 and the support member 18 thus form a unit, which is positioned in the water passage, i.e. the passage 14a-c, and the through hole 22 in the support member is oriented substantially axially with the longitudinal axis of the passage 14a-c, in such a way that water will be led to it.
  • the sealing member 16 has the shape of a sleeve, i.e. a cylinder with an axial through-hole 20 and the sleeve is basically substantially circular with an outer diameter being of substantially the same size as that of the passage 14a-c.
  • the support member 18 has a substantially circular cross-section and includes a first end which consists of a first substantially circular sleeve portion 24, i.e. a cylindrical portion through which the axial through-hole 22 extends, and a second end which consists of a second substantially circular sleeve portion 26, which according to the above discussion is also run through by the axial through-hole 22.
  • Both sleeve portions 24, 26 are positioned coaxially relative to each other, and have essentially the same outer diameters. Furthermore, the first sleeve portion 24 is connected to the second sleeve portion 26 by means of axial connection waist 28.
  • the connection waists 28 are preferably one or two in number, and consist of slender beams, whereby the through-hole which forms the water passage in this mid- portion will be to the major part limited by the inner wall of the sealing member, i.e. its hole 20. The idea behind this relates to noise dampening and will be described further on.
  • the outer diameter of the sleeve portions 24, 26 of the support member is equal to, or is slightly less then the inner diameter of the sealing member 16, i.e. of its hole 20,
  • the first sleeve portion 24 is adapted to radially support a first end 30 of the sealing member 16 from the inside, said first end 30 having a substantially circular cross-section.
  • the second sleeve portion 26 is adapted to radially support a second end 32 of the sealing member 16 from the inside, said second end 32 also having a substantially circular cross-section.
  • the task of the support member 18 is thus to ensure that the sealing member 16 maintains its shape and also to contribute to facilitating the insertion of the sealing member 16 in the passage 14a-c.
  • the sealing member 16 is, as mentioned above, a sleeve, and in the first axial end 30 of the sleeve, there is an outer portion where the sleeve has a somewhat lesser outer diameter, i.e. is reduced, and where the material thickness of the sleeve is slightly thicker than in the rest of the sleeve, which means that the inner diameter of the sleeve is thus less than in other parts of the sleeve.
  • the sealing member 16 is provided with an internal chamfer 36.
  • the chamfer 36 has a slightly rounded shape, see Fig.
  • this sealing lip 34 is preferably shaped in such a way that when the support member 18 is inserted into the sealing member 16, the lip 34 will extend a distance outside of the first sleeve portion 34 of the support member 18, see for example Fig. 5.
  • the through-hole 20 in the sealing member 16 is adapted in such a way that the support member 18, when mounted in the sealing member 16, together with the sealing member 16, forms a substantially smooth water passage, i.e. where the "inner peripheral surface" of the water passage is smooth.
  • the inner diameter of the sealing member 16 varies in such a way that the portions where both sleeve portions 24, 26 of the support member 18 is to function as supports, there are corresponding recesses in the inner surface of the sealing member 16, i.e. the wall of the hole 20.
  • the sealing member 16 there are elevated portions 38, corresponding to the inner recesses, said elevated portions 38 forming the outer diameter of the sealing member 16, i.e. the diameter which earlier in this text has been referred to as the outer diameter of the sealing member 16, which is the diameter including the elevated portions 38 and which is equal to, or slightly lesser than the diameter of the passage 14a-c.
  • the outer diameter of the sealing member 16 which is the diameter including the elevated portions 38 and which is equal to, or slightly lesser than the diameter of the passage 14a-c.
  • portions 40 of the outer peripheral surface of the sealing member 16 that have not been provided with elevated portions 38, and that thus have a lesser outer diameter than the elevated portions 38.
  • These portions 40 cannot abut against the inner peripheral surface 14a-c, and thus gaps (not shown) are formed between the inner peripheral surface of the channel and the outer peripheral surface of the sealing member, at these portions 40. The function of these gaps will be described further on.
  • the first end 30 of the sealing member 16 is further provided with at least one radial sealing flange 42 arranged on the outer peripheral surface of the sleeve inside of the sealing lip 34.
  • the sealing flange 42 will, in an assembled state, abut the inside of the passage 14a-c.
  • the number of sealing flanges 42 is two in the exemplary embodiment, but is should be understood that the number may of course be varied and that another number may be suitable in another embodiment.
  • the other sleeve portion 26 of the support member 18 is provided with means for cooperation with an inlet opening 44 in a valve unit 46.
  • These means include a radial flange 48, being arranged in the outer end of the sleeve portion 26, and which is adapted to abut - with a first side 50 - against a surface around the inlet opening 44, as well as against a guide member 52 being arranged to extend a distance into the inlet opening 44.
  • the guide member 52 is really not a continuation of the second sleeve portion 26, but is positioned on the second side of the flange 48, and the through-hole 22 - which extend through the second sleeve portion - extends further through the guide member 52 and forms a continuous hole with the latter.
  • the function of the guide member 52 is to lead in the water into a small kidney-shaped opening (not shown) at the bottom of the inlet opening 44 of the valve unit 46. Since this kidney-shaped opening is smaller than the inlet opening 44, and also has another shape, the hole 22 has s cross-section on a portion 54 at the guide member 52 and the sleeve portion 26, which is continuously reduced and changes shape, i.e. from a circular to a kidney-shape, towards the kidney-shaped opening, see Fig. 6. Since the cross-section is continuously changed, a smooth transition between the various shapes is obtained and turbulence may be maintained at a low level.
  • the shape of the hole in the portion 54 at the second sleeve portion 26 and the guide member 52 is adapted to the opening in the bottom of the inlet 44 of the valve unit 46.
  • the opening of the valve unit 46 has another form than a kidney-form, it is suitable to adjust the shape of the hole in this portion 52 so that the will coincide with each other.
  • both these flanges 48 and 56 that are arranged on top of each other, will abut a rim in the passage 14a-c. This will be shown in conjunction with the embodiments.
  • the support member 18 is preferably manufactured in a relatively stiff polymer material, for example by injection molding.
  • the choice of polymer material may take place due to the desired purpose. If one has a connection device 10 through which water with high temperature will pass, it is suitable to chose a temperature-resistant material.
  • An example of such a material is polyphenylene sulfide (PPS).
  • the sealing member 16 By manufacturing the sealing member 16 in a flexible and noise dampening material, pressure shocks and sound waves may be absorbed and prevented from spreading to the pipes. This is achieved due to the fact that the water passage in the connection device 10 according to the invention, in the mid-portion between the sleeve portions 24, 26 of the support member 18, to the largest extent is limited by the inner way of the sealing member 16, and that this wall to the largest extent does not abut the inner peripheral surface of the passage 14a-c, there being a gap allowing the wall to move somewhat in a radial direction, i.e. inwards towards the center of the hole 20 of the sealing member 16 and outwards towards the inner peripheral surface of the passage 14a-c.
  • the sealing member 16 is preferably manufactured from a flexible and noise dampening material, such as for example rubber, may preferably be injection molded.
  • a flexible and noise dampening material such as for example rubber
  • ethylenepropylene rubber (EPDM) may for example be used.
  • the noise dampening of the connection device 10 is, however, not the most important function of the invention, the most important function instead being the sealing between the device 10 and the member connected to he water supply system, which member in the various embodiments will be denoted 60a, 60a, 60b and 60c respectively.
  • the principle for the sealing is that the sealing member 16 is adapted to cooperate with at least one hole periphery 62a, 62b and 62c respectively, in the member 60a-c connected to the water supply system, and that the internal chamfer 36 in the sealing member 16 is adapted, by means of a pressure generated by the water, to press against the hole periphery 62a-c and to seal against it. Cooperation thus takes place by means of the sealing lip 34 and the internal chamfer 36, which abuts the hole periphery 62a-c of the member 60a-c.
  • the sealing member 16 and the passage 14a-c in the housing 12a-c are thus suitably dimensioned relative to the hold periphery 62a-c of the connecting member 60a-c, in such a way that the inner diameter of the hole periphery 62a-c equals or is slightly less than the outer diameter of the sealing lip 34.
  • the internal chamfer 36 in the lip 34 will - by means of the pressure generated by the water - be pressed substantially radially, i.e. outwards, against the hole periphery 62a-c and effectively seal against it. No water may then find its way in between the hole periphery 62a- c and the outer surface of the sealing member 16.
  • the sealing member 16 may, as previously mentioned, preferably be parallelly connected to a further corresponding sealing member 16 by means of its flange 56, and the support member 18 may in the same way be parallelly connected to a further corresponding support member 18 by means of its flange 48.
  • this connection is made already upon manufacture of the parts, and there is of course no theoretical limitation on how many support members 18 and sealing members 16, respectively, that may be connected in this way.
  • connection device 10 according to a first embodiment will now be described in conjunction with a so called single-lever blender, which is connected to pipes for both water- and cold water.
  • the connection device 10 is thus adapted to lead warm and cold water, respectively, to the valve unit 46 from two member connected to a water supply system, that in the embodiment consist of two connection pipes 60a.
  • the connection pipes 60a that are usually manufactured from copper or stainless steel, are provided with a widened end 62, which will constitute the hole periphery in this embodiment.
  • the single-lever blender is in itself substantially conventional and includes a blender housing 66 with a spout and a maneuvering lever, see Fig. 3.
  • the lever may, according to known prior art, be considered as a two-armed lever, which is joumalled about a vertical axis as well as about a horizontal axis, the shorter lever arm of which being adapted to affect a moveable valve plate which cooperates with a fixed valve plate in a valve unit, said valve unit being provided with two inlet openings 44 for cold and warm water, respectively, and an outlet opening, which communicates with the spout.
  • the valve unit 46 is assembled in the blender housing 66 by means of two screws extending on respective sides of the valve unit 46, said screws being tightened in screw-holes in the blender housing 66.
