摘要： The invention relates to the external sealing and joining of piping. More particularly, the invention provides an improved seal profile which is suitable for use inside pipe couplings. The invention provides a twin-lip seal profile particularly useful in combination with a pipe coupling, the seal comprising: a substantially flat base element, having a first (inner) face and a second (outer) face and two outer edges. Two spaced-apart support blocks projecting upwardly from the first face of the base element, each support block having an outer and an inner face. Two lip members projecting from the outer edges of the base element, the lip members overlapping and resting on the closest support block and leaving a hollow space between the base element, the lip member and the outer face of the support block. The seal profile being characterized in that the plane or line of contact between the lip member and the support block, when extended towards the center of the profile, slopes to more closely approach the substantially flat base element, thus forming a wedge-like effect when pressure is applied to the lip members, the wedge-like effect preventing undesired outward movement of the lip members.
摘要翻译：本发明涉及管道的外部密封和接合。更具体地，本发明提供了一种适于在管接头内使用的改进的密封轮廓。本发明提供了一种特别适用于管接头的双唇密封型材，该密封件包括：具有第一（内）面和第二（外）面和两个外边缘的基本平坦的基体元件。两个间隔开的支撑块从基部元件的第一面向上突出，每个支撑块具有外表面和内表面。两个唇形构件从基部元件的外边缘突出，唇形构件重叠并搁置在最靠近的支撑块上并且在基座元件，唇形构件和支撑块的外表面之间留下中空空间。密封轮廓的特征在于，当朝向轮廓的中心延伸时，唇形构件和支撑块之间的平面或接触线倾斜以更接近基本平坦的基部元件，从而形成楔形效应，当对唇部构件施加压力，楔形效应防止唇部构件的不期望的向外移动。

摘要： A roller air supply structure has a stationary compressed air supply having a stationary pressure chamber that can be loaded with pressure, and a rotatable roller that has at least one opening in a surface thereof operable to be loaded with compressed air from the stationary compressed air supply. The roller is surrounded in the axial area of the opening to be loaded with compressed air in the circumferential direction at least in sections by the stationary pressure chamber. The compressed air supply has a sealing element that can be moved by loading the pressure chamber with compressed air from a position of rest into a sealing position and by relieving the pressure of the pressure chamber to ambient pressure from the sealing position into the position of rest. The sealing element and the pressure chamber are constructed such that when the sealing element is in the position of rest there is no connection between the roller and walls of the pressure chamber, and when the sealing element is in the sealing position there is a pressure-tight connection between the walls of the pressure chamber and the roller.

摘要： Production of concrete bell and spigot pipes having a recess (13, 53) in the socket which is relative shallow and is produced using a core (40; 60). The seal (20) made of a relative compact elastomer (16) body may be inserted with its seating portion into the recess (13, 53) at any time after the pipe has been produced. The sealing portion (32) which functions as a combined compression and lip seal has a circular recess of triangular cross section before being pressed together when a pipe system is assembled.
