Abstract
A sealing strip is provided for sealing a space between two parts of a machine, for example, a rotary engine. The two parts form a groove for receiving the sealing strip. The sealing strip includes a filler piece, at least one spring element, at least one sealing body and a separating element. The filler piece is divided into two filler piece parts along the longitudinal direction. The filler piece parts are capable of independent longitudinal displacement with respect to one another. A spring element is arranged between the filler piece parts for preloading the filler piece into the groove. Each sealing body is formed in a frame-like shape for surrounding an end of the filler piece. The separating element is arranged between the filler piece parts for separating the filler piece parts and extends longitudinally from an end of the divided filler piece to at least a point where a sealing body surrounds the divided filler piece. The present invention minimizes leakage rate and does not require excessive spring forces.
