A flush toilet includes a base and a bowl assembly defining a bowl. The bowl assembly is mounted to the base and defines a discharge opening at a lower end of the bowl. A waste ball valve assembly is mounted to the flush toilet for selectively opening and closing the discharge opening of the bowl assembly. A common sealing member operates to seal the bowl to the base and to wipe a ball of the waste ball valve assembly as the waste ball valve assembly is selectively opened and closed. The common sealing member has a generally horizontal portion for wiping the ball of the ball valve assembly and a compressible cylindrical portion upwardly extending from the generally horizontal portion. The cylindrical portion is compressed between the base and the bowl to define a seal therebetween.

Sealing member for a flush toilet

A flush toilet includes a bowl assembly defining a bowl. The bowl assembly has a discharge outlet at a lower end and a ledge circumferentially extending about a substantial portion of the bowl. The bowl has a rear surface that is generally flat and vertical. The rear surface transitions to the ledge as the bowl continues clockwise and counter clockwise from the rear surface. A horizontal dimension of the ledge increases as the ledge continues from the rear surface to a front of the bowl. An angle of the ledge increases as the ledge continues from the rear surface to the front. A maximum slope of the ledge is located proximate the front. A nozzle is mounted to the bowl assembly for pressurizing a source of flush water and delivering the source of flush water to the bowl for rinsing and flushing of the bowl. The nozzle is positioned at a rear portion of the bowl and produces a first flow of water in a first circumferential direction about the bowl and a second flow of water in a second circumferential direction about the bowl. The second circumferential direction is opposite to the first circumferential direction. The ledge cascades the first and second flows of flush water down the bowl as the first and second flows of water move in the first and second circumferential directions, respectively.

Flush toilet with improved flow pattern

A pump assembly includes a housing and first and second valves. The housing has a fluid inlet port and a fluid outlet port. The first and second valves are substantially identical valves both including a mounting portion, a valve seat and a valve body. The mounting portion has a first end and a second opposite end. The first and second ends are both selectively mountable to a conduit defining a fluid path. The valve seat is interconnected to the mounting portion. The valve body is interconnected to at least one of the mounting portion and the valve seat for movement relative to the valve seat between a seated position and a closed position. The valve body includes a first side and a second side and is operative to seal against back flow from the first side and open to positive pressures on the second side. The first valve is mounted to the fluid inlet port with the first end such that the first valve normally functions to only permit fluid to flow into the housing. The second valve is mounted to the fluid outlet port with the second end such that the second valve normally functions to only permit fluid to flow out of the housing.

Pump assembly with reversible one-way valves

A toilet system includes a toilet and a pump assembly. The toilet has a bowl and a base. The base has a hopper for receiving waste from the bowl. The pump assembly is operative for pumping a source of flush water to the bowl and for pumping the waste from the hopper. A first flexible conduit interconnects the pump assembly and the bowl. A second flexible conduit interconnects the pump assembly and the hopper. The pump assembly is flexibly interconnected to the toilet for independent positioning relative to the toilet.

Flush toilet

A reduced water consumption flush toilet for a motor vehicle includes a bowl assembly, a waste ball valve assembly and a water valve assembly. The bowl assembly defines a bowl and a discharge opening at a lower end of the bowl. The waste ball valve assembly is mounted to the flush toilet for selectively opening and closing the discharge opening of the bowl assembly. The water valve assembly delivers a source of flush water to the bowl. The water valve assembly includes a water valve operable in a water valve open condition and a water valve closed condition. The flush toilet further includes a common actuator for controlling both the waste ball valve assembly and the water valve assembly. The common actuator is movable from a first position to an intermediate position and from the intermediate position to a second position such that in the first position the waste ball valve assembly closes the discharge opening and the water valve assembly is in the closed condition, in the intermediate position the waste ball valve assembly closes the discharge opening and the water valve assembly is in the open position for adding water to the bowl, and in the second position the waste ball valve assembly opens the discharge opening and the water valve assembly is in the open position for flushing the bowl.
