System for flushing of a vacuum toilet in an aircraft
First Claim
1. A drain system for a vacuum toilet for an aircraft, the drain system comprising:
- a drain pipe system;
a first closing device; and
a second closing device;
wherein the drain pipe system is provided with at least a first pipe section and a second pipe section that is connected to the first pipe section;
wherein a connection of the first pipe section is connectable to a bowl of a vacuum toilet, and a connection of the second pipe section is connectable to a vacuum system;
wherein the first closing device is provided in the first pipe section;
wherein the second closing device is provided in the second pipe section downstream of the first closing device; and
wherein the first closing device and the second closing device are coupled to each other such that in each instance only one of the first and of the second closing devices can be open.

Abstract
A system for flushing a vacuum toilet, includes a drain that is connected to a drain conduit, which vacuum toilet is connectable to a vacuum system by way of a suction valve. With the use of a combined valve including, for example, a flow-optimised intermediate storage device, inflow nozzle, bypass conduit with silencer and hose odor seal, the flow noises at the urinal bowl drain, urinal bowl overflow and upper end of the bypass conduit can be effectively suppressed. With the combination disc valve or the shut-off valve and suction valve, during the suction process the air stream is only drawn through the bypass conduit with a special odor seal and silencer.
