BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a sanitary water fixtures consisting mainly of a basic body, designed to be concealed or surface mounted, a cartridge mounted on the basic body and a housing, as well as one or more operating handles which are in engagement with the cartridge and in under certain conditions also secure the housing in its position.
The present invention relates, more particularly, to a sanitary water valve, especially a mixing valve, with a connection unit for the connection to the water supply lines and with a cartridge, located in the housing and receiving the control elements, whereby the connection unit is located in the housing and has passages for the hot and cold water. According to the invention the walls of the passages of the connection unit have openings into which noise mufflers can be inserted.
BACKGROUND OF THE INVENTION
When valves of sanitary fixtures are suddenly closed or opened, considerably loud noises can be produced. Since in many countries noise pollution regulations require a low noise level, many attempts have been already made to develop water noise mufflers to be built into sanitary systems. So for instance it is known to insert into a pipe an insert of an elastic material, namely in a support ring.
From WO 89/01585 a mixing valve is known, wherein in one of the cartridge valve plates a flow guiding piece is inserted. Naturally for this purpose the size of the passages in the valve plates have to be suitably selected.
In the fixture according to CH-A-628 967 a damper precedes the valve whereby the water flow is turned on and off. The damper is made in one piece from a permanently elastic material and has passages. It is built into a blind bore in the housing and the supply lines for cold and hot water have to be correspondingly connected with the passages, i.e. the connection geometry has to be specially fitted for these arrangements.
OBJECT OF THE INVENTION
It is the object of the present invention to provide a valve of the type described with sound damping, without having to change the cartridge elements or the connections of the fixture.
SUMMARY OF THE INVENTION
According to the invention, the walling of the passages of the connection unit have openings into which noise mufflers are inserted. In this way neither the cartridge nor connection geometry of the fixture has to be modified. If the noise muffler is mounted in the direct water flow in the case of concealed fixtures, then brass can be saved on the basic body, since no additional bores have to be provided, because the noise mufflers are inserted into the walls, i.e. into the water path to the cartridge.
DESCRIPTION OF THE DRAWING
The above and other objects, features, and advantages will become more readily apparent from the following description, reference being made to the accompanying drawing, the sole FIGURE of which is a cross sectional view of a valve according to the invention.
SPECIFIC DESCRIPTION
The mixing valve has a conventional construction, namely, a valve body 2 with inlets 4 and outlet 5, wherefrom the water is then supplied to a usual dispensing location, for instance to a tub spigot or a shower. For the control of the water flows a cartridge 1 is provided, which can be connected with operating handles by means of which the delivery of cold and hot water can be controlled. The construction of such a cartridge is generally known and does not need to be repeated. One or more noise mufflers 8 held by a connection unit 6 are provided in the water path. Further a muffler support 7 is provided and seals 3 are provided at the connection points between individual components.
In the conventional construction, especially in the case of concealed fixtures, the noise mufflers 8 are located between the concealed basic body and the water supply lines 4. This increases the overall dimensions, which in turn requires larger concealed boxes, and thereby also larger rosettes. This is avoided by the present invention. In the case of concealed fixture the overall dimensio
