Concealed sanitary valve unit
First Claim
1. A concealed valve unit comprising in combination(a) a housing adapted to be inserted into a wall opening for flush mounting therein, said housing having openings therein that are sized to accomodate two water supply lines and two output water lines,(b) a valve body arranged within said housing, said valve body including control elements and passageways that are adapted to control the flow of water through the valve body,(c) operating members operatively associated with said valve body and extending through a mounting window located in said housing,(d) said valve body having two spaced apart outer connecting faces, said connecting faces containing openings that communicate with said passageways in said valve body that are adapted to control the flow of water through said valve body,(e) connecting nuts that are adapted to be threaded onto the ends of said water supply lines and onto the ends of said output water lines, each of said connecting nuts having a planar end face that is adapted to sealingly engage with the portions of said connecting faces of the valve body that contain openings,(f) spaced apart clamping means mounted within said housing for engaging said end connecting nuts so that when said clamping menas are brought together they will clamp the planar end faces of said connecting nuts in sealing engagement with said openings in the connecting faces of the valve body, thereby establishing controlled communication from said water supply lines, through said valve body and out through said output water lines.

Abstract
In a concealed sanitary valve unit the valve body received in a concealed outer housing is made from plastic material. In order not to exert excessive mechanical loads, particularly torsional and tensional loads onto the valve body improved clamping means are provided which will exert onto the valve body only small compressive loads. Connection of the valve body to the feed and work lines extending through the wall is achieved without making use of threadings, since connecting nuts are fixed to the feed viz. work lines having plane end faces adapted to sealingly engage plane connecting faces of the valve body.

13. A concealed valve unit comprising in combination
(a) a housing adapted to be inserted into a wall opening for flush mounting therein, said housing having openings therein that are sized to accomodate at least one water supply line and at least one output water line, (b) a valve body arranged within said housing, said valve body including control elements and passageways that are adapted to control the flow of water through the valve body, (c) operating members operatively associated with said valve body and extending through a mounting window located in said housing, (d) said valve body having two spaced apart outer connecting faces, said connecting faces containing openings that communicate with said passageways in said valve body that are adapted to control the flow of water through said valve body, (e) connecting nuts that are adapted to be threaded onto the ends of each of said water supply lines and onto the ends of each of said output water lines, each of said connecting nuts having a planar end face that is adapted to sealingly engage with the portion of said connecting faces of the valve body that contain openings, (f) spaced apart clammping means mounted within said housing for engaging said planar end faces of said connecting nuts so that when said clamping means are brought together they will clamp the planar end faces of said connecting nuts in sealing engagement with said openings in the connecting faces of the valve body, thereby establishing controlled communication from each water supply line, through said valve body and out through each output water lines.

14. A water flow unit comprising in combination
(a) a housing adapted to be inserted into a wall opening for flush mounting therein, said housing having openings therein that are sized to accomodate two water supply lines and two output water lines, (b) two bridging tubes arranged within said housing, said bridging tubes each interconnecting one water supply line with one output water line, said bridging tubes being located between support tabs located on the interior of the housing, (c) connecting nuts that are adapted to be threaded onto the ends of said water supply lines and onto the ends of said output water lines, each of said connecting nuts having a planar end face that is adapted to sealingly engage with an end portion of a bridging tube, (d) spaced apart clamping means mounted within said housing for engaging said planar end faces of said connecting nuts so that when said clamping means are brought together they will clamp the planar end faces of said connecting nuts in sealing engagement with the openings in said bridging tubes, thereby establishing controlled communication from said water supply lines, through said bridging tubes and out through said output water lines.
