Description

Inlet valve

The invention relates to a 2ulaufventil for the needs of ianitärfacnes, especially for installation in mixer taps obtained by the elimination of other existing Verschleiavorc, än _<f e a virtually unlimited service life has is secured against rotation during Schlieävorgang and as jiinbaueleiaent when applying üei mixer taps achieved a substantial reduction in gesture costs.

The invention is based on a known embodiment of a valve body held by spring force in a permanently closed position, the purpose of which is to open the flow by means of a suitable device against the spring force from the seat. äuiu uei play i3t by the DTtAS 1 298 79β proposed this arrangement for a solenoid valve in that the movement of the magnet by means of a tappet causes the valve body to tilt. Furthermore, DT-Ao 2 041 279 proposes lifting the valve body by means of a cam disk in ochwenkauslaufen caused by the movement of the swivel tube, the twisting of which moves a tappet acting on the valve body in a non-positive manner.

The valve of the invention similar to this known one Arrangement of a valve body which is constantly held in the closed position by spring force is thereby ge ~ indicates that the movement of the valve body by the with valve upper parts known rising spindle takes place, which carries a correspondingly long mandrel attachment. Durcn this design results in the following advantages:

409840/0165

1) The spindle wear is reduced to a minimum, since the Spindle does not need to take up any closing forces.

2) The valve has an extremely simple construction and is correspondingly cheaper Production.

3) By appropriately dividing the inlet valve into upper and lower parts can be a significant simplification of the approximately associated battery body achieved by the fact that the two pieces from both sides in one Inserted through-hole provided for this purpose in the battery body and by screwing them together in the battery body be tightly braced.

The figure shows such a design in the middle section with special, inventive training of the ünterstiickes as S-connector, as it is when connecting such surface-mounted batteries is common.

is the lower piece designed as an S-piece. To the heel A plate 3 equipped with water passages is inserted into a recess. On her leans with a shoulder 4, the closing spring 5 centers, which presses the valve body 6 against the seat ring 7 - the seat ring 7 in turn rests on a second shoulder 8 and is sealed by the snap ring 9 by an O-ring held in place.

The sealing body 6, in the cavity 10 of which the spring end is guided, träct on a central "pin approach 11 unbuttoned sealing body 12. The pin 11 forms the pressure point for the plunger 13 of the upper part 14. fca this upper part is the one with 0 ~ ring o'egen vjasserzutritt sealed spindle 15 with the operating handle 16 high and low viewable.

The upper piece is connected to the lower piece by screwing it into the thread 18 of the cylindrical extension piece 17 firmly connected. It is used with the appropriate Seals on the two passages 19 iia extension piece 20 of the battery housing 21 and so clamps the inlet valve with the battery body. The cylindrical extension 17 carries radial bores 22 for at a suitable height the passage of the water to the battery. ? \ from the figure the great simplification is evident:

The battery body has been installed with expensive means at the points where the usual upper parts are otherwise are and separate connection pieces with union nut screw connections must be arranged for screwing to the normal S-pieces, only through holes.

Of course, the inlet valve of the invention can also be used as a normal straight-way valve in a corresponding oil design Equipped with a suitable outlet, e.g. as a standing taps in wash basins and sinks or as a wall tap Find application. As an example, the figure shows a training as a wall tap. Here the lower piece carries 1 instead of the S-bend the central threaded extension 23 is screwed into the wall-side supply line.

The extension 20 of the B'igur 1 in its continuous liourung 19 upper and lower parts sealed by screwing are installed, trusts the outlet in this version

It goes without saying that instead of the rising spindle, a non-rising spindle is used and the mandrel attachment 13 is arranged on the rising taper.
