Abstract:
1. A valve device comprising: a receptacle including an upper port for coupling to an upward sprayer device, a lower port for coupling to a downward sprayer devices, a front wall having an upper orifice and a lower opening formed therein, said receptacle including an upper housing attached said front wall thereof and communicating with said receptacle via said orifice of said front wall, for allowing water to flow from said housing into said receptacle via said orifice of said front wall, said receptacle including a vertical partition disposed therein, to separate an interior thereof into a front chamber and a rear chamber, said front chamber of said receptacle being communicating with said housing via said orifice of said front wall, and said rear chamber of said receptacle being communicating with said upper port of said receptacle, said vertical partition of said receptacle including a lower aperture formed therein, and defined by a peripheral valve seat, for allowing said front chamber and said rear chamber of said receptacle to be communicated with each other, said receptacle including a lateral panel attached to bottom of said vertical partition, to separate said front chamber and said rear chamber from said lower port of said receptacle, and to form a space to communicate with said lower port of said receptacle, said receptacle including a lower casing attached to said front wall and having a chamber formed therein and communicating with said lower port of said receptacle via said space that is defined between said lateral panel and said lower port of said receptacle, said front wall including a lower opening formed therein, for communicating said front chamber of said receptacle with said chamber of said casing, said casing including a passage formed therein, and laterally aligned with said opening of said front wall and said lower aperture of said vertical partition, a container attached to said housing, a control valve element received in said container to control the water to flow into said housing, and then to flow into said front chamber of said receptacle via said orifice of said front wall, a tubular member attached to said casing to block said passage of said casing, said tubular member including a ring member engaged in said opening of said front wall, to form as a valve seat for said opening of said front wall, and including a bore formed therein, and including at least one pathway formed therein and communicating with said chamber of said casing, to allow the water to flow from said front chamber of said receptacle into said chamber of said casing, via said at least one pathway of said tubular member, and a stem slidably received in said bore of said tubular member, and including a plug for selectively engaging with said ring member of said tubular member and said valve seat of said vertical partition, said plug being selectively engageable with said ring member of said tubular member to block said opening of said front wall, and to prevent the water from flowing into said casing via said opening of said front wall, and to allow the water to flow from said front chamber into said rear chamber of said receptacle via said lower aperture of said vertical partition of said receptacle, and said plug being selectively engageable with said valve seat of said vertical partition to block said lower aperture of said vertical partition of said receptacle, and to prevent the water from flowing from said front chamber into said rear chamber of said receptacle via said lower aperture of said vertical partition, and to allow the water to flow into said casing via said opening of said front wall of said receptacle.
