Abstract: A control device for a door closer is arranged to control flow of pressure medium within a body part of the door closer and comprises an adjustment member supported by threads on the body part of the door closer, and in cooperation therewith, a separate substantially hollow control member, which is arranged to restrict the flow of the pressure medium when necessary. Turning of the adjustment member with respect to the body part of the door closer brings about movement of the control member in the axial direction of the control device for providing the desired control. The control member is arranged to be attached to the adjustment member in the radial direction so that movement of the control member with respect to the adjustment member in the axial direction is prevented.

Abstract: A locking device for selectively securing two movable objects in desired positions relative to each other includes a cylinder and a piston movable within the cylinder and defining first and second working chambers of variable volumes. A fluid exchange connection provided on the piston includes a flow chamber having openings that communicate with the working chambers. A valve body slidably received on the piston in sealed relation is biased by a spring into a position closing the opening from the flow chamber to first working chamber. When the fluid pressure in the second working chamber exceeds a predetermined amount and acts on the valve body, the valve body is moved against the spring bias and opens to allow fluid to flow through the fluid exchange connection. In the open position, a larger area of the valve body is exposed to the pressure in the second chamber. A restriction in the flow path between the flow chamber and the first chamber produces a pressure drop between the flow chamber and the first chamber and allows the fluid exchange connection to remain open with a reduced pressure in the second chamber. The device thus provides for a large holding force when the valve body closes the opening and a small resistance to movement after the valve body is moved from closed. By providing two spring-biassed valve bodies acting in opposed directions, control of movements of objects in opposite directions is obtained.
Abstract translation: 用于将两个可移动物体相对于彼此选择性地固定在期望位置的锁定装置包括可在气缸内移动并限定可变体积的第一和第二工作室的气缸和活塞。 设置在活塞上的流体交换连接件包括具有与工作室连通的开口的流动室。 以密封的关系可滑动地容纳在活塞上的阀体被弹簧偏压到从流动室将开口关闭到第一工作室的位置。 当第二工作室中的流体压力超过预定量并作用于阀体时，阀体抵抗弹簧偏压运动并打开以允许流体流过流体交换连接。 在打开位置，阀体的较大面积暴露于第二室中的压力。 在流动室和第一室之间的流动路径中的限制在流动室和第一室之间产生压降，并允许流体交换连接在第二室中以减小的压力保持打开。 因此，当阀体关闭开口时，该装置提供大的夹持力，并且在阀体从关闭状态移动之后具有较小的阻力。 通过提供两个在相反方向上作用的弹簧偏压阀体，可以获得相反方向上物体运动的控制。

Abstract: A door closer (20) is attachable to a door (24) and includes a cylinder (36) which forms a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door. After the door (24) has been opened to a position, for example, of ninety-five to one hundred degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82). This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door. A passageway (150) is formed in cylinder (36) to allow fluid to flow relatively freely from chamber (44) to reservoir (82) until an inward end (56) of piston element (50) has travelled a prescribed distance "x." This prescribed distance of travel represents the opening of door (24) to ninety-five to one hundred degrees from the door's normally closed position.

Abstract: A door closer wherein a housing defines a fluid-containing space and rotatably supports a shaft which is articulately connected with a pivotable door panel. A piston in the housing divides the space into a chamber and a compartment and has a toothed rack which mates with a pinion on the shaft so that the piston moves in the housing in response to rotation of the shaft as a result of pivoting of the door panel and vice versa. One or more springs in the chamber bias the piston in a direction to pivot the door panel toward closed position. A channel in the housing establishes communication between the chamber and the compartment during an initial stage of movement of the door panel from closed position at which time the piston moves in a direction to reduce the volume of the chamber. A bypass in the piston provides a path for the flow of fluid from the chamber into the compartment during a following stage of pivoting of the door panel toward open position, and the cross-sectional area of such path increases gradually in a direction from the chamber toward the compartment. The bypass can be provided in the peripheral surface of the piston or in the peripheral surface of the body of a check valve which is installed in the piston and serves to permit the fluid to flow from the compartment into the chamber during pivoting of the door panel toward closed position.
