摘要： A door closer has a housing for connection to a door and a drive spindle (10) coupled to the door. As the door moves the spindle (10) and housing (11) rotate relative to one another. The relative movement is translated by a piston and cam mechanism (21, 22) into a force that is used to separate a pair of magnets (28). The magnetic attraction of the magnet pairs (28) serves as a force to resist opening of the door and biases the door from an open to a closed position. At least one first magnet is coupled to the drive member and at least one second magnet (32) coupled to the housing. The magnets are arranged in the housing with their opposite poles facing one another such that there is a magnetic force of attraction between them. At least one further biasing spring (36) may be provided to provide a biasing force after the magnetic force has diminished by separation of the magnets.
