    摘要： This invention relates to an overhead door closer with slide arm assembly (1) having a toothed pinion (6) that is eccentrically supported and presents a circular rolling curve, which pinion meshes with a toothed rack (5) arranged at a piston (4). The invention concentrates on a particular embodiment of the rolling curve and of the teeth (9) of the toothed rack (5) in adaptation to a toothing of the pinion (6). Furthermore, the invention concentrates on an improved embodiment of the delayed closing operation in order to achieve an optimized movement pattern of the piston (4) within the housing (2) of the overhead door closer with slide arm assembly (1).

    摘要： A door closer of the kind having a piston slidably mounted in a bore containing hydraulic fluid and dividing that bore into damping and reservoir chambers. Drive means is connected to the piston to respond to sliding movement of the piston and translate that into rotary motion for driving door connected linkage. The piston is spring influenced in a direction towards the damping chamber, and fluid pressurized by the piston tending to move in that direction bleeds from the damping chamber through an escape port which is controlled by a biased and movable closure member. Normally the closure member is biased into a rest position in which it blocks passage of fluid through the escape port, but it responds to fluid pressure in the damping chamber to move into an open position at which fluid can bleed through the escape port. The time taken for the closure member to travel from the rest to the open position is a delay time during which the piston is freed from external influence so as to be movable in a door closing direction, but is temporarily restrained against such movement by the closure member. That delay time can be varied by adjusting the rest position of the closure member and/or by adjusting the rate of fluid flow from the escape port to the reservoir chamber.
