Abstract: A door closer comprises a housing having a door-closing spring and a fluid-filled door checking or retarding chamber in which a vane rotates in response to opening and closing of the door. The vane permits fluid to leak past its edges on movement in the door opening direction but forces fluid ahead of it and through a novel bypass passage on movement in the closing direction. The adjustable bypass passage comprises an adjustably positioned flexible seal which bears on the vane-supporting shaft, the degree of pressure therebetween regulating the rate of fluid flow through the passage defined by said seal and shaft.
Abstract translation: 门关闭器包括具有门关闭弹簧和流体填充的门检查或延迟室的壳体,其中叶片响应于门的打开和关闭而旋转。 叶片允许流体在门打开方向上移动时渗透其边缘,但是在关闭方向上移动时迫使流体在其前方并通过新颖的旁路通道。 可调节旁路通道包括一个可调节定位的柔性密封件,其承载在叶片支撑轴上,其压力程度调节通过由所述密封件和轴限定的通道的流体流速。
