ADAPTER FOR LIQUID SUPPLY MEANS

Abstract

The invention relates to auxiliary devices for a liquid supply means. The adapter with a liquid supply single channel consists of the upper component provided with the connection element and the portion of the single channel located in the upper component, and the lower component, which is provided with the ascending and the descending longitudinal pass-through portions of the single channel, the throttling means and the air gap. The portion of the single channel of the upper component is formed by assembling the connection element of the upper component to the lower component. A part of the single channel consists of the ascending longitudinal channel portion and the portion of the single channel located in the upper component and allows for the throughput of liquid to the throttling means at a uniform rate. The ascending longitudinal channel portion and the channel portion of the upper component which are in fluid communication with each other have a preferably identical cross-section. The connection element of the upper component is made in the form of an arc-shaped recess located inside the upper component. The external upper surface of the lower component has a protrusion which follows the shape of the recess, with the groove along the entire length of the protrusion, that follows the shape of the protrusion and limited by two side walls. The portion of the single channel located in the upper component is formed by connecting the upper and the lower components by internal free space of the upper component recess and the groove of the lower component protrusion and is predominantly arc-shaped.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Adapter 1 for liquid supply means consists of the upper component 2 and the lower component 3 (FIGS. 1 and 2).

[0026] The upper component 2 is provided with the arc-shaped recess 4 which is formed during the upper component 2 molding process (FIGS. 1 and 2).

[0027] The lower component 3 is provided with the ascending 7 and the descending 8 longitudinal pass-through portions of the liquid supply single channel. The external upper surface of the lower component 3 has the protrusion 5 which follows the shape of the recess 4 (FIGS. 1 and 2) with the groove 6 (FIGS. 3 and 4) along the entire length of the protrusion 5 that follows the shape of the protrusion 5 (FIG. 4), and limited by two side walls 13 (FIGS. 3 and 4).

[0028] The portion 9 of the single channel of the upper component 2 is formed by connecting the upper component 2 and the lower component 3 (FIGS. 1, 2 and 3). When connecting of two components, the side walls 13 of the protrusion 5 (FIG. 4) engage in the recess 4 of the upper component 2 (FIGS. 1 and 2). As far as the height of the side walls 13 of the protrusion 5 (FIGS. 3 and 4) is less then height of the recess 4, the portion 9 of the single channel of the upper component 2 (FIGS. 1, 2 and 3) is formed by inner free space of the recess 4 and the groove 6, and cross-section of the portion 9 of the single channel has an oval shape (FIG. 3). As the recess 4 of the upper component 2 has an arc-shaped form (FIG. 2), and the protrusion 5 with the groove 6 (FIG. 4) follows the shape of the recess 4, so formed portion of the single channel of the upper component 2 also takes on an arc-shaped form (FIGS. 1 and 2). Formed portion 9 of the single channel of the upper component 2 is in the liquid communication with the ascending longitudinal portion 7 of the single channel of the lower component 3 and the cross-section diameter of the portion 9 of the single channel can be several millimeters more or less than cross-section diameter of the ascending longitudinal portion 7 of the single channel of the lower component 3 (FIGS. 1 and 2).

[0029] Therefore, liquid supply single channel formed in the adapter has a part that consists of the ascending longitudinal portion 7 and the portion 9 of the single channel of the upper component 2 where cross-section of the channel mostly does not change along the whole length of the indicated part. Besides formed portion 9 of the single channel of the upper component 2 has an arc-shaped form, and as opposed to the closest analogue solution, transition from one portion of the channel to the other passes smoothly without abrupt changes of the channel cross-section. This allows to avoid abrupt liquid blow against the walls of the single channel and provide uniform rate of the liquid along the indicated part of the single channel. Indicated above construction of the adapter with formed liquid supply single channel leads to simultaneous decrease of noise and vibration when liquid passes along the single channel and also to decrease of potential turbulent mode.

[0030] The throttling means 10 is located in the lower component 3. The throttling means 10 is made in the form of through passage which communicates with the descending longitudinal portion 8 of liquid supply single channel through the air gap 11 (FIGS. 1 and 2).

[0031] The air gap 11 is made in the form of horizontal recess in the descending longitudinal portion 8 of liquid supply single channel (FIGS. 1 and 2) and communicates with the throttling means 10 from one side and with the descending longitudinal portion 8 of liquid supply single channel from the other side (FIGS. 1 and 2).

[0032] Opposed to the closest analogue solution, where a throttling means is executed as separate part, the throttling means 10 in claimed invention is a part of the lower component 3.

[0033] It should be noted that the recess 4 of the upper component 2, the protrusion 5 with the groove 6 (FIGS. 3 and 4) executed along the whole length of the protrusion 5 and limited by the side walls 13, the throttling means 10, and the air gap 11 of the lower component 3 communicating with the throttling means 10 are formed during the molding process of the upper 2 and the lower 3 components. As a result noise and vibration additionally decrease during liquid supplying through the single channel, also adapter assembling performed faster and easier.

[0034] By means of connection of the recess 4 of the upper component 2 and the protrusion 5 of the lower component 3 is provided the additional fixation of two components before their welding or gluing. The upper 2 and the lower 3 components after assembling are welded or glued with each other using for example, cyanoacrylate cement.

[0035] Components glued to each other can be placed into the housing 12 (FIG. 1). FIG. 1 depicts an embodiment of the adapter 1 for liquid supply means executed as purified liquid tap (not presented in figures), where the ascending 7 and the descending 8 longitudinal pass-through portions stands proud from external lower surface of the lower component 3 for convenience of mounting pipes for liquid where the upper 2 and the lower 3 components of the adapter can be executed predominantly in cylindrical shape.

[0036] FIG. 2 depicts an embodiment of the adapter 1 for liquid supply means executed as faucet with purified liquid supply line (not depicted in the figure), where length of the adapter much more exceeds it's width. As opposed to the adapter's embodiment depicted in the FIG. 1, the upper 2 and the lower 3 components of the adapter are, for example, arc-shaped or S-shaped in cross-section.

[0037] Within the features of invention the adapter described above functions as follows.

[0038] Liquid flows along the ascending longitudinal pass-through portion 7 of the single channel, then passes the portion 9 of the single channel of the upper component 2. The cross-section of the portion 9 is predominantly the same as the cross-section of the ascending longitudinal pass-through portion 7. And then liquid with increased rate passes through the throttling means 10, executed, for example, as the throughway opening. Then liquid passes through the air gap 11 to the descending longitudinal pass-through portion 8 of the liquid supply single channel and comes out of the adapter 1.

[0039] The description of the present invention submits a preferred embodiment of the invention. It can be changed within the claimed set of the claims, so the wide use of the invention is possible.
