    • A device is presented which automatically controls the interaction of a medium (2) with an external environment (21), the temperature of which varies or remains constant. In addition to the medium, the device includes a mechanism for providing constant effectiveness of the medium in the external environment, and an automatic drive mechanism (3) which drives the mechanism for providing constant effectiveness of the medium in the external environment. Advantageously, the device includes a receptacle (18) for the medium, and the receptacle includes a housing (1) incorporating the mechanism for providing constant effectiveness of the medium in the external environment, which is beneficially a movable vent or an expandable vent. The automatic drive mechanism is advantageously a temperature-responsive member or a temperature-responsive fluid movement device. The temperature-responsive member, which manifests variations in the surface area thereof as the temperature thereof is raised, is beneficially one of the following: a linear spring, a spiral metallic spring, a multi-metallic spring, a polymeric spring, or a pop spring. A preferred embodiment of the device includes at least one static vent (6) positioned within the housing in alignment with at least one movable vent positioned therein, and the at least one movable vent is driven by the automatic drive mechanism (3) to move in relation to the at least one static vent, thereby providing constant effectiveness of the medium in the external environment by affording varying exposure thereof as the temperature of the external environment (21) varies.

    • A regulator for maintaining a constant partial vacuum in a region includes a path, through which fluid passes from the region to a vacuum source, and a piston (2) movably mounted at a constriction point (30). The piston has a frontal face (15), exposed to fluid in the path upstream of the constriction point (30). A piston distal face (16), exposed to a reference pressure, such as the pressure of region and piston weight tends to widen the path at the constriction point (30). A force is exerted on the piston by a spring (21) under compression, in a direction that tends to narrow the path at the constriction point. A buffering gas, introduced to the area between the piston's skirt (29) and the piston mounting structure (65), may be used to keep fumes from backing up into the region and/or to provide a bearing.
    • 用于在区域中保持恒定部分真空的调节器包括流体从该区域传递到真空源的路径以及可移动地安装在收缩点(30)处的活塞(2)。 所述活塞具有在所述收缩点(30)上游的路径中暴露于流体的正面(15)。 暴露于参考压力(例如区域和活塞重量)的活塞远端面(16)倾向于使收缩点(30)处的路径变宽。 在压缩下,弹簧(21)的力在趋向于缩窄收缩点处的路径的方向上施加在活塞上。 引入到活塞裙部(29)和活塞安装结构(65)之间的区域的缓冲气体可用于保持烟气不被备用到该区域中和/或提供轴承。

    • A regulator controls the flow of gas from an environment, through a region and to an evacuation means. The regulator's fluid path is bounded on opposite sides by two hingedly mounted parallel plates (51, 55). Each of the plates have a conduit side (52, 56), facing the fluid path (10), and a reference side (53, 57) facing a reference pressure. The first plate's reference-pressure side may be exposed to the region's pressure, and the second plate's reference-pressure side may be exposed to the environment's pressure. The regulator also includes an impeder (96, 97) which includes a fixed grate (97) and a movable grate (96) hingedly attached to the plates at points (86, 87) distal from the pivot points (84, 85). As the movable grate moves with respect to the fixed grate the impedance on the flow varies.
