DESCRIPTION:

BRIEF SUMMARY
DESCRIPTION

1. Technical Field
The invention relates to a ventilator which is adapted for the supply of untreated exterior air to a room, and comprises a valve seat with a valve body setable thereto, means for connecting the ventilator to an exterior air duct, means for resetting the valve body and locking means for retaining the valve body in a set position.
2. Background Art
A large number of different ventilators are known for the supply of untreated exterior air to a room, e.g. flap valves and disc valves in an outside wall, and slit valves in, or under the window structure. All have the following disadvantages to a greater or less degree. They are optionally adjustable in different opening positions and can therefore, inter alia by unsuitable setting, give rise to draughts or the opposite, i.e., insufficient ventilation. If they are permanently open, or opened too much in relation to the ventilation need, they result in considerable energy losses for heating the supplied exterior air during the cold season.


DISCLOSURE OF INVENTION

The object of the invention is to provide, for the purpose of saving energy and improving environment, a ventilator of the kind disclosed in the introduction, and which is well-suited for equipping with an air filter and sound insulation, and which is easily settable between distinct minimum and maximum positions, said positions not being disturbed on resetting or cleaning, and which furthermore is well-suited for operation automatically with low power consumption.
The intended result is obtained by the ventilator being given the characterizing features apparent from the following patent claim 1.


BRIEF DESCRIPTION OF DRAWINGS

An embodiment of the invention will now be described while referring to the appended drawings.
FIG. 1 is a section through the valve body and valve seat of the ventilator in the room and through its members closest to it in an exterior air duct.
FIG. 2 is a section through a mechanical coupling according to II--II in FIG. 1.
FIG. 3 is a partial section to a larger scale of an end portion of the mechanical coupling in FIG. 1.
FIG. 4 illustrates to the same enlarged scale a coupling member in the mechanical coupling according to FIG. 3, seen from one side.
FIG. 5 is an end view to the enlarged scale of the coupling member according to FIG. 4.
FIG. 6 is a side view in the enlarged scale of an axially displaceable mounting means for the coupling member in the mechanical coupling according to FIGS. 1-5.
FIG. 7 is a side view to the enlarged scale of the mounting member according to FIG. 6.
FIG. 8 is a cross section to the enlarged scale according to VIII--VIII in FIG. 1.
FIG. 9 is a development along IX--IX in FIG. 8, illustrating to the larger scale a crenelated profile on a coupling engagement detail co-acting with the coupling member.
FIG. 10 is a section to the larger scale according to X--X in FIG. 1, through a device for adjusting the maximum opening of the valve body.
FIG. 11 is a side view to the enlarged scale of a device for releasing the valve body for cleaning.
FIG. 12 is an end view of the device according to FIG. 11, and to the same scale as FIG. 11.


MODE FOR CARRYING OUT THE INVENTION

The ventilator is adapted for supply of untreated exterior air to a room. The ventilator has a valve seat 1 and a valve body 2 in the form of a disc settable in relation to the valve seat. Means are arranged in the connection with the valve seat for connecting the ventilator to an exterior air duct 4 through the outer wall 5, and is illustrated in FIG. 1 solely by a pipe stub 3, which shall be assumed to be provided with conventional attaching means for installing in the outer wall 5.
In the shown embodiment, the valve has alternative operating means 6 and 7 for resetting the valve body 2 in relation to the valve seat 1.
By a coupling 9 the valve body 2 is carried by stationary support means 8, in the form of two flat carrying arms which are oriented with their greatest cross-sectional dimension in the flow direction of the air.
The coupling 9 is of the
