An apparatus for controlling the waste outlet of a toilet includes, according to an implementation, a motor comprising a Hall effect sensor that detects the rotation of the motor and generates a position signal in response thereto; a mechanical actuator coupled to the motor; a door coupled to the mechanical actuator, wherein the door is disposed at the waste outlet of the toilet; logic circuitry that receives the position signal, generates a control signal to move the door based at least in part on the position signal, and transmits the control signal to the motor. The motor operates according to the control signal to drive the mechanical actuator to move the door.

A controller for a vacuum sewage system includes a housing having multiple chambers. Certain chambers are maintained under atmospheric pressure or vacuum prior to activation of the controller. Ports, valves, orifices and air flow paths located in the housing control the rate of air flow between groups of the chambers during activation of the controller.

A rail vehicle includes a graywater line which is in communication with the surroundings of the rail vehicle directly or by way of a collecting container. The graywater line is equipped with a pressure protection valve, which protects a graywater line section upstream of the pressure protection valve from pressure surges occurring in the surroundings of the rail vehicle. The pressure protection valve is constructed as a pinch valve which is controlled by a control device in order to protect the graywater line section from pressure surges.

Disclosed is a sewer system including a sewage receptacle, sewer piping connected to the sewage receptacle by means of a discharge valve, a mechanism for generating vacuum in the sewer piping, and a control mechanism for controlling the discharge valve. In order to achieve a more rapid closing of the discharge valve after discharge of the sewage from the sewage receptacle, the vacuum sewer system further comprises an aeration device in direct fluid communication with the discharge valve. The control mechanism is arranged to control the aeration device. Also disclosed is a discharge valve (2) for such a vacuum sewer system.
摘要:
A system for flushing a vacuum toilet in an aircraft, with a bowl drain for removing toilet waste water from a bowl, a drain line, a bypass flow line for feeding-in air, a drainage valve and a waste water line. The bowl drain and the bypass flow line are connectable to the drain line, and the drainage valve on the input side is connectable to the drain line, and on the output side is connectable to a waste water line. In an implementation of the vacuum toilet as a vacuum urinal, the system may provide either water flushing or waterless flushing.

Embodiments include tubular diaphragm valves with a preformed mechanical closure point and optionally concave or convex convolution areas located near the flanges. These mechanical closure points and convolution areas give the embodiments an extended operational life, as compared to that of conventional cylindrical diaphragms.
摘要:
Embodiments of the invention described herein thus provide improved flush valves that are designed with improved venting features and improved inlet designs. The described venting features and inlet designs, either alone or in combination, can help prevent ingestion of waste into the interior of the valve.
摘要:
A vacuum toilet unit having a urinal function with reduced noise emission, system design size and system weight, in which vacuum toilet unit a triggering device for triggering the vacuum valve is adapted in such a manner that the triggering unit may not be triggered when a sit-down toilet is in use as intended.
摘要:
The invention relates to an odor seal for a vacuum toilet drain system whose cross section in the state of no throughflow tapers off in such a way in the downstream direction that the interior walls on the downstream end of the odor seal rest against each other so that the odor seal in a downstream direction allows throughflow while in the opposite direction it blocks throughflow, wherein the downstream end of the odor seal is closed in the state of throughflow and no throughflow of the odor seal. Furthermore, the invention relates to a drainage device comprising such an odor seal and a sieve which is arranged upstream of the odor seal. Moreover, the invention relates to a vacuum toilet system for an aircraft, comprising such an odor seal or a drainage device.
