A dump bucket toilet that enables the construction of a toilet that has a low profile and that avoids splashing of water. A barrier ( ) lies over much of the first side portion of the bucket to prevent the very rapid discharge of water from the bucket into the surrounding tank when the bucket is tipped, but to instead allow water to be discharged through an opening ( ) of moderate size. This avoids splashing and keeps the bucket in it dump position for a few seconds to avoid the bucket scooping up water at the bottom of the tank. A return wall ( ) at the bottom of the middle of the tank retains water at a second side portion of the tipped bucket to urge the bucket to tilt back to the filled position.

Dump bucket toilet with controlled discharge and return

A vacuum assist toilet provides an efficient flushing in a tank of relatively low height. A container assembly (36) includes a largely sealed container (34) that lies within the tank (12) to hold water that is dispensed in a flushing so as to create a vacuum at the top of the tank for application to the toilet bowl outlet. The flush valve (40) lies within the container, and the lower portion of the container is isolated from tank water surrounding the container, so water used during a flushing is obtained primarily by the outflow of water within the container and through a valve seat at the bottom of the container. A baffle (130) largely surrounds the region containing the flush valve, to produce an earlier closing of the flush valve.

Low profile vacuum toilet

A flush valve device is described for use in a toilet that includes a pressured water source, which can drain away water in the event of excess pressure with minimal modification to the toilet and which facilitates initial operation of the flush valve device. The flush valve device includes a valve member (16, FIG. 2 ) which lifts off a valve seat (22) at the beginning of a flushing, the valve member carrying a pressure operated relief valve (50) which dumps water at excess pressure through the opening (52) within the valve seat, to avoid the need for additional fluid-tight couplings in the water source. The valve member includes a sealing portion (60) which normally lies against the valve seat and which is lifted completely away from the valve seat during a flushing. A manually operated flushing mechanism which lifts the valve member off the valve seat, is coupled to the outer end (80) of the sealing portion, with the outer end of the sealing portion being flexible enough that it progressively peels away from the valve seat at the beginning a flushing. The peeling away allows the escape of some water through the valve seat to facilitate the liftoff of the rest of the sealing portion from the valve seat.
