摘要： A door closer pivoted on a door at least includes a case and a piston. When the door is open, the door closer blocks a communicating hole of the case by an oil sealing ring of the piston to allow an oil filled in the door closer cannot flow through the communicating hole. As a result, the open door can be held in a predetermined position.

摘要： An automated door closure system regulate the release and closure of a door in a door assembly that includes a primary door, a secondary door, and a door frame. The system includes a door closer, a control unit, and an automatic input sensor. The door closer, which is connected between the secondary door and the door frame and includes a cylinder and an operating rod, biases the secondary door toward a closed position. The control unit includes a motive device and a rod catch element. The rod catch element, which may be moved by the motor, is positioned in proximity to the operating rod to adjustably prevent the secondary door from being closed. The automatic input sensor detects a door assembly use condition. The control unit controls the motive device based on the detected condition to move the rod catch element, allowing the door closer to close the secondary door.

摘要： An automatic door closer constructed for releasably holding a door in a predetermined partly open position mainly comprises a piston arranged in a cylinder bore of a housing and operatively connected to a closer shaft mounted in the housing turnable about an axis substantially normal to that of the cylindrical bore so that the piston will be reciprocated in the bore during turning of a door connected to the closer shaft. The piston divides the bore in the housing in two compartments filled with fluid and a coil compression spring in one of the compartments biases the piston to an end position corresponding to the closed position of the door. The piston is provided with two passages therethrough, in one of which a one-way valve is arranged permitting flow of fluid only from the one compartment into the other during movement of the piston in door opening direction. The other passage is closed when the door reaches a predetermined partly open position preventing thereby fluid flow from the other compartment into the one compartment so that the door is held in this partly open position. The elements for closing the other passage comprise a valve member of a holding valve biased by a spring to a closed position so that the door may be moved in closing direction from the partly open position in which it is held only by application of an outer force applied thereto overcoming the biasing force of the spring acting on the valve member.
