- a thermostatic throttle is pivoted rotationally, and above it, below the ribs a pressure throttle is suspended rotationally.
- the partition has an opening, through which a cylindrical spigot of the thermostatic throttle passes into the chamber of the thermostat.
- In the surface of the spigot there is a hole, in which a curved end of the profiled spring is arranged and the second end of the spring is mounted rotationally in a hole in the side closure.
- the spring has a bulge which abuts a temperature sensor.
- the sleeve of the flow channel and the air-intake pocket connected to the channel and the air-outlet pocket enclose the window frame from the outer side forming a kind of overlay.
- the intake ventilator known from the Polish patent application No. P. 407593 has a flow channel, an air-intake box and an air-outlet pocket mounted above a window frame, and the air-intake box, which is located on one side of the channel has a stub-pipe and a partition with an opening, and the partition has a flange and side closures provided with guides and guide channels and it has outer walls of the guides.

- the lower edge of the air-intake box is included in the top surface of the outer cavity of the window, while the bottom edge of the air-outlet box is included in the top surface of the inner cavity of the window.
- a disadvantage of known and described intake ventilators is a high degree of complexity of their design and the necessity for additional insulation of an air-flow channel if the ventilator is used in a building having concrete construction of lintels of window openings, or under cold climate, which results in a significant increase in size and weight of the ventilator.
- the new intake ventilator should have a significantly simplified design, smaller dimensions and better thermal insulation from the side of the lintel of the window opening. It should be a modular construction that allows for easy replacement of components, which creates opportunities for further development.
- the new design of the intake ventilator should be distinguished by a special technical and functional suitability, which provides proper ventilation and, at the same time, reduces the consumption of thermal energy required for heating the ventilation air during the heating season.
- the intake ventilator according to the invention has a thick-walled shell made of a resilient material having good heat insulation.
- a concavity composed of an air- intake cavity, an air-outlet cavity and a flow channel recess, which is provided with a rib.
- the upper part of the thick-walled shell forms a plate provided with openings in which profiled ribs are disposed.
- the thick-walled shell has also two side walls, a closure of the air intake and a closure of the air outlet, and those elements surround the concavity on four sides.
- the flow channel recess is closed from below with the horizontal partition having a slanting fault, and said horizontal partition through seals adheres to an upper surface of a window rail.
- a pressure throttle is located, while inside the air-intake cavity a thermal air-flow controller is positioned.
- the thermal air-flow controller consists of two profiled guides connected by means of yokes, each of the guides has a longitudinal groove and two 3 longitudinal slots. In the grooves two movable lamellar throttles are located. The throttles have openings and binders. In the slots of the guides two pairs of bars are placed.
- the yokes have arms with openings and they are assembled by means of screws to the brackets equipped with mounting sleeves.
- the air-intake cavity is covered from the bottom with a flap provided with two guides, in which the side closures of the flap are located and said closures are provided with ribs having axles of rotation.
- the air-outlet cavity is covered from the bottom with a masking frame provided with two guides, in which there are catches of the side closures of said mask frame and said closures have ribs with transverse openings in which the axles of rotation of the throttle are mounted.
- the closure of the air intake from the side of the air-intake cavity has a transverse step, while the closure of the air outlet in its cross-sectional shape is similar to right triangle, and on its hypotenuse wall from the side of the air-outlet cavity there is a transverse nest wherein a throttle is located.
- the slanting fault of the horizontal partition is deflected from the plane of the partition by an angle a within the range from 20° to 30°.
- the recess of the flow channel which is closed with the horizontal partition having the slanting fault, creates a passage which connects the air-inlet cavity with the air-outlet cavity.
- the pressure throttle has the shape of a flat spread rectangle provided with protrusions disposed along opposite longer sides of the rectangle.
- One part of the protrusions is attached to the horizontal partition having the edge which is the rotation axle of the throttle. Between the edge, the longer side of the rectangle, and the edges of said protrusions rectangular openings are formed. During the rotation of the throttle the edges of the protrusions abut against the profiled ribs.
- the throttle is preferably made of a flexible material.
- the bars of each pair at one end are constrained in the yokes and their free ends are connected by connectors equipped with compensator of elongations to the lamellar throttles.
- Both lamellar throttles have relative movement Hmiters.
- the bars are made of a material having a high coefficient of thermal expansion.
- the lamellar throttles have an identical spacing of the openings, furthermore, the binders are wider than the openings.
- the thermal air-flow controller abuts with the flat surface of its profiled guide on the window rail and the edges of the guides of the flow abut respectively on the horizontal partition and on the horizontal surface of the transverse step.
- the embodiment of the flap is provided with a silencer and the flap is pivotally suspended.
- the axles of rotation are mounted in the openings on the arms of the yokes.
- brackets for a filter Inside the guides of the flap there are brackets for a filter.
- the flap has a magnetic lock consisting of magnets.
- the brackets having the mounting sleeves are secured directly to the window rail with screws.
- a silencer Inside the guide of the masking frame there is a silencer which abuts on the slanting fault and on the vertical surface of the window rail.
- the closures of the masking frame are bolted directly to the window rail with screws.
- the intake ventilation according to the invention has surprisingly specific technical advantages, because it enables easy and simple installation of the ventilator just above the window, and in the same time it does not interfere in the structure of the window and thus does not require slits in the window frame profile and does not reduce the technical parameters of the window.
- the intake ventilator according to the invention has very good thermal insulation from a lintel of the window opening, and thanks to the elastic thick-walled shell it has a small height above the window frame.
- the invention can be applied to windows of different designs and of different widths of structural profiles.
- the intake ventilator according to the invention has high mechanical strength and high rigidity. Therefore the intake ventilator according to the invention can be installed in the gap between the hole in the wall and the window frame.
- Another advantage of the invention is its ease of installation on the window frame, a good air-tight of the connection of the window frame and a lintel, and immunity to thermal expansion of the window frame.
- An additional advantage of the invention is to allow for use of a system of automatic control of two parameters, ambient air temperature and pressure difference, which provides higher comfort and higher energy efficiency.
- the use of flexible pressure throttle eliminated, first of all, internal noises of the working intake ventilator.
- the system adding the deformations of bars of the thermostatic sensors significantly increases the sensitivity of the thermal air-flow controller.
- the solution according to the invention has a modular construction that creates opportunities for f rther development and allows for easy replacement of elements determining such technical parameters as the efficiency and acoustic insulation, as well as creates the possibility of using another automatic control, including electric.
