    Abstract: A door closer with integral check action comprising a rigid rod movable inwardly and outwardly of a tubular housing which is adapted to be mounted on a door. The rigid rod is pivotally connected to a rigid link plate itself pivotally connected to a fixing plate for mounting on the door frame. A spring within the housing urges the rod inwardly to close the door. On one side of a transverse wall, through which the rod extends, is a fluid filled chamber in which moves a piston, carried by the rigid rod. Valve means on the piston act to resist only inward movement of the piston as the door is closed by the force of said spring and the rate of closure of the door is thereby controlled without substantially restricting outward movement of the piston in response to opening of the door.

    Abstract translation: 具有整体检查动作的门关闭器,包括可向内并向外移动的刚性杆,其适于安装在门上。 刚性杆枢转地连接到刚性连接板本身,该刚性连接板本身枢转地连接到用于安装在门框上的固定板。 外壳内的弹簧向内推动杆关闭门。 杆延伸的横壁的一侧是一个充满流体的腔室,活塞由刚性杆承载。 当门被所述弹簧的力闭合时,活塞上的阀装置仅抵抗活塞的向内运动,因此可以控制门的关闭速度,而不会基本上限制活塞响应于开口的活动而向外运动 门。
