Flow control devices for convector heaters

A flow control device to be connected to an intake conduit of a convector heater mounted in a first space (A1) of a building allowing the intake conduit to be placed into communication selectively with the first space (A1) or with a second space (A2) above a ceiling (S) that delimits the first space (A1) from the top, the device comprising:

• a casing in the shape of a cylindrical tube having in a first portion thereof, facing in a mounted condition towards the intake conduit, a plurality of first openings and in a second portion thereof, facing in the mounted condition towards to opposite side of the intake conduit, a plurality of second openings, the casing being closed at its end opposite to the one intended to be connected to the intake conduit and being arranged to be mounted onto the ceiling (S) in such a manner that the first and second openings allow placement of the inside of the casing into communication with the first space (A1) and the second space (A2), respectively;
• a closure member in the shape of a cylindrical tube which is mounted within the casing and is axially slidable relative to the casing between a first position, in which the closure member leaves the first openings open and closes the second openings, and a second position, in which the closure member closes the first openings and leaves the second openings open;
• and
• actuation elements for controlling the axial sliding movement of the closure member relative to the casing between the first and the second position.
