Abstract (en)
[origin: EP0253979A1] 1. Motorised pressure valve for cabins of railway carriages or the like, especially for passenger cabins of excursion trains, in which a valve plate (1) having slots (4) parallel to one another is arranged movable in its plane transverse to the longitudinal direction of the slots (4) relative to fixed guide plates (2, 3) likewise having slots (5, 6), characterized in that the valve plate (1) is arranged between two guide plates (2, 3) which support the valve plate (1) on both sides in the region of the webs between the slots, with a small play transverse to the plate plane, and the surfaces of the valve plate (1) and the two guide plates (2, 3) movable relative to one another have a coating of a material of limited elasticity with small coefficient of friction, the webs between the slots of the valve plate (1) being wider than the slots of the guide plates (2, 3) and a motorised drive with a sensor control being provided, which converts pressure differences into switch pulses.
