A DEVICE FOR SEALING A WING OF A WINDOW, A DOOR OR THE LIKE IN RELATION TO A FRAME ASSOCIATED THEREWITH Abstract of the Disclosure Doors and windows may be sealed in a particular- ly efficient manner by arranging on their periphery a flexible sealing tube which is adapted to be expanded by means of a pump which serves to pressurize a liquid with which the tube is filled. The invention is directed to a novel pump which is adapted, independently of the existing temperature, to adjust the desired liquid pressure in the sealing tube. The pump of the invention, while being of compact design, is also adapted for use with windows or doors covering very large openings. This is made possible by the use of an independent supply reservoir for the pres- surized liquid, the reservoir being connected to said pump and being also connected to said sealing tube by means of a first valve which is adapted to be operated by a closing device. Between the pump and the sealing tube there is pro- vided a second valve which is adapted to be opened towards the sealing tube. -1-
