A passenger transport vehicle, such as a rail vehicle, has at least one sanitary module and at least one fan for conveying waste air from the sanitary module. A control unit controls the volumetric flow of waste air from the sanitary module. The control unit is formed for at least two volumetric flows of waste air, which differ from one another and differ from zero. The volumetric flows are conveyed by the at least one fan, at least on the basis of a state of the sanitary module.

The application relates to roof segments for constructing a roof of a carriage body for a rail vehicle for passenger transport, in particular for use in short-haul operation, such as underground and suburban trains, the rail vehicles or the train units formed by same must be accelerated and decelerated at short intervals. The roof segments are designed in the form of plates, shells or half-shells and consist of an outer wall and an inner wall at a distance to same. At least two roof segments are configured in such a way that the protruding region of the outer wall or inner wall of one roof segment is interlockingly, force-lockingly and/or integrally connected to the non-protruding region of the outer wall or inner wall of the neighbouring roof segment. The roof segments consist at least partially of a fibre-reinforced plastic composite.

The present invention extends to a double canopy covered wagon. Interior canopy frame supports support an interior canopy over a portion of a wagon flooring surface and under larger exterior canopy frame supports. The exterior canopy frame supports support an exterior canopy over the interior canopy. Including interior and exteriors canopies increases insulation relative to a single canopy. Further, since the exterior canopy frame supports are larger than the interior canopy frame supports, air can flow between the interior and exterior canopies. Air flow between the canopies in combination with increased insulation facilitates more effective climate control inside a wagon.

A cargo space air management system for a vehicle includes a body defining one or more cavities therein and one or more ports configured to enable fluid communication through the one or more ports into at least one of the one or more cavities. The body is configured to attach to be placed in a cargo space of the vehicle, and the body is deployable from a first state to a second state, wherein in the second state the body covers a portion of the cargo space and forms an air filled cavity within the body.

A railcar air conditioning duct according to one aspect which guides air fed from an air conditioner mounted on a railcar. The railcar includes: a duct wall forming an air flow passage which guides air in a car longitudinal direction; and a plurality of through holes lined up in the car longitudinal direction, the through holes being open at the duct wall as air outlet ports through which the air in the air flow passage is blown from the air flow passage toward a passenger room. A ratio of an opening area of one of the through holes to an area of one of a plurality of partial regions formed by dividing, in the car longitudinal direction, an inner surface of a lower wall portion such that in plan view, the regions contain the respective through holes falls within a range of 2.0% or more and 7.5% or less.

A railway car fitted with an induction generator comprising magnets and electrical conductors for generating electricity, comprising a chassis comprising at least one axle with two wheels, wherein the axle is mounted in two bearings located near the two sides of the railway car, wherein the wheels are located on the outer side of the bearings, and wherein the generator comprises a rotor and a substantially cylindrical stator, which stator extends concentrically around the rotor, wherein the rotor is fixedly mounted around and on the axle, wherein the stator is mounted to the inner side of one of the bearings, in axial abutment therewith.

Some embodiments of the present disclosure provide a side wall component of a railway vehicle, and a railway vehicle. The side wall component of a railway vehicle includes: a side wall, including a side wall body; and a plurality of side wall upright columns, connected with the side wall body respectively, the plurality of side wall upright columns being provided along a length direction of the side wall body at an interval, wherein an auxiliary air duct of a railway vehicle is formed between at least two of the plurality of side wall upright columns and the side wall body in the length direction of the side wall body. According to some embodiments of the present disclosure, an auxiliary air duct of a railway vehicle is directly formed on a side wall, so that the railway vehicle is compact in structure.

A fluid flow control valve includes a valve body, a closing member arranged in the valve body and configured so that it can have at least one first position, called the open position, in which it allows the flow of fluid to flow freely in the valve body, and at least one second position, called the closed position, in which it prevents the fluid flow from flowing in the valve body between the fluid inlet and the fluid outlet, an electric actuator of the closing member that is suitable for being able to control the position of the closing member in the valve body, characterized in that the electric actuator is arranged in the valve body so that it can be cooled by the flow of fluid flowing in the valve body.

Some embodiments of the present disclosure provide a side wall component of a railway vehicle, and a railway vehicle. The side wall component of a railway vehicle includes: a side wall, including a side wall body; and a plurality of side wall upright columns, connected with the side wall body respectively, the plurality of side wall upright columns being provided along a length direction of the side wall body at an interval, wherein an auxiliary air duct of the railway vehicle is formed between at least two side wall upright columns and the side wall body in the length direction of the side wall body. The embodiment of the present disclosure enables the railway vehicle to be compact in structure.

The invention relates to a method for supplying air at a controlled temperature to a cabin of a surface vehicle in which at least one air cycle device is used, comprising at least one motorized turbocompressor. The air inlet of the turbine is arranged to receive a compressed airflow from the compressor. At least one exchanger is interposed between the air outlet of the compressor and the air inlet of the turbine. The air inlet of the compressor is arranged to receive air at a pressure greater than or equal to atmospheric pressure. The invention likewise relates to a surface vehicle comprising at least one such air cycle device.
