A vacuum toilet system including a toilet bowl, a wastewater tank under vacuum, an ejection valve for ejecting air from the wastewater tank, means for monitoring the frequency of activation of the ejection valve, and a sensor for activating the ejection valve.

The invention relates to a sanitary arrangement, in particular, a mobile sanitary arrangement in a motor vehicle such as a coach, having a wastewater-collection tank which has a floor and a sidewall that enclose a tank interior, and an inlet connection and an outlet device. The outlet device has an outlet opening with a connection coupling for the connection of a suction-extraction arrangement and a suction-extraction channel, which, starting from the outlet opening, extends downward in the direction of gravitational force to an intake opening within the wastewater-collection tank.

A cabin for a vehicle includes a cabin wall having an opening and a door for opening and closing the opening. The door is moved about a rotational point and includes a movable door leaf which has a concentric segment. The cabin wall additionally forms a door stop in the closing direction of the door. The door leaf further has a linear segment with a fixed end and a free end. The linear segment adjoins the concentric segment at the fixed end in the closing direction of the door, and the free end of the linear segment forms a closing edge in the closing direction of the door. The closing edge lies against the door stop when the door is closed. A vehicle including an interior having the cabin is also provided.

The invention relates to a method for the installation of a shower and an installation system for the implementation of the method. The method comprises the following steps: arranging at least one installation frame at a wall, with the wall being arranged at a water supply device; providing at least one side wall, with the side wall having at first side and a second side; arranging the first side of the side wall at the installation frame; arranging a shower fixture at the second side of the side wall, and guiding at least one water line from the water supply device to the shower fixture; as well as arranging a shower base plate showing a drain at a floor, which abuts the wall, and arranging the drain of the shower base plate at a floor drain.

An extraction device for discharging a mixed fluid, in particular containing feces, from a collecting tank of a rail vehicle comprises a housing having a mixed fluid inlet and a mixed fluid outlet, a flow passage which extends in the housing between the inlet and the outlet, a retaining latch mounted to the housing and adapted to cooperate with a corresponding recess on the collecting tank and is pivotably reciprocal between a locked position and an unlocked position, a shut-off member reciprocable between a release position and a blocking position, and a handling means or actuator mounted to the housing for actuation of the shut-off member. The handling means is operatively connected to the retaining latch in such a way that upon the movement of the retaining latch into the unlocked position the shut-off member is put into the blocking position.

A water supply system includes a water storage tank having a storage tank outlet, the water storage tank configured to store a volume of water at a first pressure. A pressure tank is in fluid communication with the water storage tank and is periodically fillable with water from the water storage tank. An air source is fluidly connected to the pressure tank to pressurize the volume of water in the pressure tank to a second pressure greater than the first pressure. A pressure tank output line is fluidly connected to the pressure tank to output water from the pressure tank.

Waste transfer system for a toilet of a public transport vehicle that discharges into an on-board waste aerated storage tank, comprising a waste intermediate tank (1), means for generating negative or positive pressure inside said waste intermediate tank (1), and a discharge valve means (3,5,6,7) to regulate the flow through a first waste passage (8) between a toilet bowl (2) and said waste intermediate tank (1) and through a second waste passage (11) between said waste intermediate tank (1) and said waste storage tank, characterized in that said discharge valve means comprise a multi-port discharge valve (3) connectable to an inlet/outlet port (4) of the waste intermediate tank (1), said multi-port discharge valve (3) being configured to provide, in a first working position, direct communication between said toilet bowl (2) and said waste intermediate tank (1) when negative pressure is supplied inside said waste intermediate tank (1) and to provide, in a second working position, direct communication between the waste intermediate tank (1) and the waste storage tank when positive pressure is supplied in the said waste intermediate tank (1).

A processing device for grey water for a rail vehicle includes a grey water container, a grey water supply in an inlet region, a drain for processed grey water in an outlet region, and a slotted filter between the inlet and outlet regions that has at least one movable sliding member which touches the base of the grey water container in a lowered position and is lifted off the base in a raised position. The base of the grey water container rises from the inlet region to the outlet region. A cleaning outflow is disposed in the inlet region on the base side. A fresh water supply for supplying fresh water is disposed in the outlet region. A rail vehicle having at least one processing device for grey water for a WC module or toilet bowl is also provided.
