Embodiment Construction

[0020] In the description, the terms "above", "below", "below", "on" are defined with respect to the customary orientation of a railway vehicle on a track.

[0021] Reference attached figure 1 , describes a railway vehicle 1 comprising a roof 2 mounted on top of passenger cars 6 of the railway vehicle and an upper roof 8 mounted on top of said roof 2 .

[0022] The air conditioning unit 10 is fixed to the roof 2 so as to be suspended from said roof 2 in order to isolate the air conditioning unit 10 from vibrations due to the movement of the railway vehicle 1 . If the air-conditioning unit 10 is fixed rigidly to the roof 2, such vibrations could in fact damage the air-conditioning unit 10 or lead to its premature wear and tear. The isolation of the air conditioning unit 10 also makes it possible to avoid transmitting the vibrations generated by the air conditioning unit to the rest of the railway vehicle. In order to isolate the air-conditioning unit 10, the latter is mounted...

Abstract

A railway vehicle, comprising a roof (2) which is formed with an opening (16) communicating with a passenger compartment (6) of the vehicle; a movable air conditioner (10) mounted over the roof (2). The air conditioner (10) comprises an air outlet (14) arranged oppositely to the opening (16). The vehicle also comprises a joining device (18) placed between the air outlet (14) and the opening (16).The joining device is arranged to allow air hermetically flow to the passenger compartment (6) through the opening (16) from the air outlet (14), and comprises a flexible body arranged to guarantee air to flow when roof (2) and the air outlet (14) of the air conditioner (10) are movable relative to each other.

Description

technical field [0001] The invention relates to a railway vehicle of the type comprising a roof forming an opening into the passenger compartment of the vehicle, an air conditioning unit mounted to be movable over said roof and comprising a an air outlet with an oppositely arranged opening, the vehicle comprising connection means between the air outlet and the opening, the connection being arranged to permit passage of gas from the air outlet through the opening in a sealed manner to the passenger compartment. Background technique [0002] On railway vehicles, the air outlet of the air conditioning unit is generally connected by a system of gaskets (eg, made of foam or bubbles) to the opening for the supply of air to the passenger compartment of the vehicle, so that between said outlet and all Provides a tight seal between the openings. [0003] Such a system is suitable for providing a seal between two stationary parts, that is, when the air conditioning unit is fixed rel...
