摘要： PCT No. PCT/DK86/00016 Sec. 371 Date Oct. 15, 1986 Sec. 102(e) Date Oct. 15, 1986 PCT Filed Feb. 21, 1986 PCT Pub. No. WO86/04971 PCT Pub. Date Aug. 28, 1986.The valve comprises a valve socket to be mounted in the wall of an inflatable body, e.g. by a snap fastener device, and a valve cap having an internal thread for threaded connection with an external thread on the valve socket. The valve socket includes an air duct with a short duct section which is connected with the outer surface of the valve socket only through a number of narrow ducts discharging at the bottom of an annular groove from whose internal edge a number of radial ducts are connected with a central bore provided in the cap. At the internal edge of the annular groove a pressure sensitive annular sealing member is provided which by the pressure from the outside will be pressed out on a larger diameter in the annular groove. By eliminating the pressure action the sealing member reoccupies its initial position in airtight abutment between the bottom plate of the annular groove and an internal annular surface in the cap.
