Abstract

A ventilating nozzle in which a tubular nozzle member is swivellable universally in a tubular housing. The nozzle member contains an obturating member adjustable to vary the effective flow of air through the nozzle member. A sleeve mounted on the nozzle member for relative rotation therebetween but restrained by the housing from rotational movement about its axis is connected by gearing to the obturating member, whereby rotational movement of the nozzle member within the sleeve will effect opening or closing of the obturating member according to the direction of the rotational movement.

Claims

1. A ventilating nozzle comprising a tubular housing arranged to be connected at its upstream end to a source of ventilating air and a tubular nozzle member mounted in the housing and having an outer surface in the shape of a zone of a sphere, whereby the nozzle member is swivellable universally in the housing, the nozzle member comprising a tubular body, an obturating member positioned within said tubular body and adjustable to vary the effective flow of air through the housing. a sleeve mounted on the body for relative rotation therebetween but restrained by the housing from rotational movement about the axis of the body and gearing connecting the sleeve to the obturating member, wereby rotational movement of the body about its axis within the sleeve will effect movement of the obturating member in accordance with the direction of said rotational movement.

2. A nozzle as claimed in claim 1 in which the obturating member comprises at least one flap valve member mounted for pivoting about an axis extending transversely of the tubular body of the nozzle member, a pivot for said flap valve member, said gearing comprising a gear member carried on said pivot and a toothed rack meshing with said gear member and extending circumferentially of the inner surface of the sleeve.

3. A nozzle as claimed in claim 2 in which the housing includes a rubbing ring extending around an inner surface thereof and engaging the sleeve, thereby to hold the sleeve from turning about the axis of the housing while permitting the nozzle member to be swivelled as a whole universally in the housing.

4. A nozzle as claimed in claimed in claim 3 including a spring strip of non-circular shape located in a gallery extending around the inner wall of the housing, the spring strip engaging said rubbing ring and holding it from rotation in the housing.

5. A nozzle member for use in a ventilating nozzle comprising a tubular body in which an obturating member is adjustable to vary the effective flow of air through the nozzle member, a sleeve mounted on the body for relative rotation therebetween and gearing connecting the sleeve to the obturating member, whereby rotational movement of the body about its axis within the sleeve will effect movement of the obturating member according to the direction of said rotational movement.

6. A nozzle member as claimed in claim 5 in which the obturating member comprises at least one flap valve member mounted for pivoting about an axis extending transversely of the tubular body of the nozzle member, a pivot for said flap valve member said gearing comprising a gear member carried on said pivot and a toothed rack meshing with said gear member and extending circumferentially of the inner surface of the sleeve.
