Definitions
- the invention relates to a damper comprising at least one lath journalled in a frame.
- the damper generally comprises a plurality of laths.
- Dampers are used widely for regulating and/or closing the flow of air and various gases.
- the ends of the laths are fixed and inflexible, and a sealing material is fastened either to the end of the lath or to the frame.
- the soft sealing material generally felt or silicone rubber, rubs against the steel of the frame during the regulating movement.
- the soft material has a high friction resistance when sliding along the steel, whereby the seal wears out rapidly and may be torn completely.
- a severe risk is caused by the frosting of the seal in the wintertime, which may locally freeze up the seal to the frame.
- the motor of the damper opens the damper, the seal may be locally torn completely.
- the damaged seal causes un- desired leakage. As a result, the energy and/or main ⁇ tenance cost is increased considerably.
- the object is to provide a novel damper which avoids the above-mentioned drawbacks.
- the damper according to the invention is mainly characterized in that a flexible seal member closely following the frame is attached to at least one end of the lath.
- the seal member may, of course, also be attached to the frame, in which case it follows closely the end of the lath.
- the ends of the laths are not fixed nor inflexible; instead, they are able to follow possible deformations in the frame.
- the lath ends are "floating" and always in close con- tact with the frame.
- the seal members of the frame function in a similar way, if the ends of the damper are fixed and the seal members are attached to the frame.
- Figure 1 is a schematic front view of a damper.
- Figures 2 to 6 are sectional views through alternative embodiments along the line A-A shown in Figure 1.
- the damper is generally designated with the reference numeral 1, the frame with the reference numeral 2, and a lath with the reference numeral 3.
- the laths 3 are preferably insulated.
- the laths 3 are turned by means of a lever mechanism, for instance.
- the lever mechanism may be known per se and is there ⁇ fore drawn merely in outline in Figure 1, the refer ⁇ ence numeral 4.
- the lath end is flexible, that is, floating in such a way that it follows closely and lightly the frame 2 irrespective of minor deformations of the frame.
- Figures 2 to 6 show alternative constructions for a flexible lath end.
- a platelike, flexible seal 6 is attached to the end of an insulated lath 3, and a "floating" cover piece 7 to be placed in contact with the frame 2 is positioned on the seal 6.
- the cover piece 7 is preferably made of metal or of wear-resistant, lubric plastic, whereby the friction remains_ low and a long service life is obtained while the sealing effect remains unimpaired.
- a flexible tongue 9 bearing against the end of an insulated lath is attached to a floating cover piece 8, and the branches 8a of the cover piece 8 are in close sliding contact, the reference numeral 10, with the side surfaces of the lath 3.
- a flexible tubular seal 11 of rubber or plastic, for instance, is attached to a cover piece 12.
- a spiral spring 15 is provided be- tween a cover piece 16 and the end of an insulated lath 3, seals 14 being fitted between the branches 16a of the cover piece and the side surfaces of the lath 3.
- the spiral spring 15 is not absolutely necessary; the seals 14 between the branches 16a of the cover piece and the side surfaces of the lath may alone provide the required flexibility.
- Figure 5 shows an embodiment in which no separ ⁇ ate floating cover piece is provided.
- a tubular seal 13 is provided between the end of an insulated lath 3 and the frame 2.
- a surface 13a to be placed in contact with the frame 2 is wear-re ⁇ sistant and lubric.
- the seal 13, or at least its portion to be pressed against the frame 2 is made of a material of high mechanical strength to prevent damage to the seal at subzero temperatures.
- the reference numeral 5 designates a journal on which the lath 3 is mounted to the frame 2.
- the frame 2 is preferably provided with an elevation 17 extending in parallel with the lath when the lath is in the closed position.
- the flexible seal member is in each case attached to the end of the lath 3, whereby the frame 2, preferably only the elevation 17 of the frame, acts as a counter surface for the seal member.
- the flexible seal member can be fastened to the frame 2, in which case the lath end acts as a counter surface.
