TOILER SYSTEM Russian patent published in 2005 - IPC

FIELD: railway transport.

SUBSTANCE: proposed toiler system contains water tank 1, water closet pan 8 with flushing manifold, meter 14 with service and pressure spaces separated from each other by diaphragm, pressure device, flushing starting device and tank-accumulator 12. Pressure space of meter of meter is connected to pressure device, and service space is connected with water tank through check valve 6 and with manifold of water closet pan through discharge valve 7 contacting with starting devices. Pressure device contains liquid pump 3, pressure pipe and reservoir 4. Pressure pipe communicates pump output with pressure space of meter. Reservoir 4 is hermetically connected to pump input and is made for constant exposure of its contents to atmospheric pressure. Capacity of reservoir exceeds capacity of pressure space of meter. When power is applied to pump 3, discharge valve 7 opens. Pump 3 delivers water from reservoir 4 into pressure space of meter, whose diaphragm feeds water into manifold 9 of water closet pan. With pump 3 switched off, diaphragm returns to initial position, and service space of meter is filled with water from tank through check valve 6.

EFFECT: simplified design, improved reliability.
