Abstract
A door operator includes a base plate with a receiving profile, a shaft housing inserted into the receiving profile, a first cylinder housing inserted into the receiving profile, a driven shaft rotatably bearing-mounted in the shaft housing, and a piston which is linearly movably guided in the first cylinder housing. The piston and the driven shaft cooperate for mutual conversion between a linear movement of the piston and a rotational movement of the driven shaft, and an energy accumulator is arranged in the first cylinder housing and cooperates with the piston.
