DETACHABLE CONNECTING OR SEALING DEVICE FOR TRANSMITTING AXIAL TENSILE FORCES OR HYDRAULIC PRESSURE FORCES

摘要

Pipe connections required in compressed air or high-pressure fluid pipe systems must remain firm and tight for long periods without maintenance, even when subjected to high test and operational pressures and sharp fluctuations and shocks. According to the invention, during assembly of the connecting or sealing element, which is made of an elastic but pressure-resistant material, a radial prestress is applied to the inner machine part (7) which nevertheless allows the machine parts (7, 8) to be inserted into one another. Sliding friction prevails between the (minimum of two) conical sliding contact faces (5) which are in mutual contact, thus ensuring the axial mobility of the connecting or sealing device even after assembly and during operation. Thus, by applying a principle of elastic wedging, a connecting and/or sealing device is created which is light, compact, low-wear, easy to manufacture, sound-absorbing and very strong and causes little wear to the machine parts to be connected.
