A version with two independently filled balloons and an opening/passage allowing for the control of the pressure or drainage of the medium (or, as the case may be, other functions like de-aeration, gas drainage, filling with inert gas and the like) from the area as between the two balloons. Working part – for properties and description following the sheet 2.2 –3. Loading part – a flexible loading tube with a sealing plug, an opening/passage in the working part of the rear balloon and the loading tube ended with a self-closing quick acting coupling system, two integrated pressure gauges with a two hose extensions diameter 10 mm, identification plate. This type of the closing balloon in this versions is made of materials that must not be exposed to any organic solvents, oil products, fats, acids, caustics and their vapours. The version made be modified based on customer requirements (following the sheet 2.2-1).
