    摘要： A check valve responsive to low cracking pressures includes first and second body portions defining a valve chamber. An inlet and outlet passage communicate with the valve chamber while a valve element received therein moves between open and closed positions responsive to pressure differentials. A stop member welded to the valve body is adapted to limit the opening movement of the valve element. An axially raised central portion of the stop member abuttingly engages the valve element to limit its opening movement yet permit fluid flow around the valve element to plural openings defined in a peripheral region of the stop member. A guide member is interposed between the stop member and valve element to urge a seal member disposed on one face of the valve element toward a seated, closed position.

    摘要： A low inertia, rapid response, low volume check valve utilizes two body members positioned in end-to-end alignment. The valve bodies have end faces which are clamped into sealing engagement with each other. A shallow cylindrical chamber is formed in one of the end faces and carries a very thin, disc like valve closure member which floats between a closed position against the face of the inlet body and an open position against the face of the outlet body. The closure member is relieved to permit fluid flow therearound and into depressions in the face of the outlet body. Preferably the outlet passage is formed by stainless steel tubing such as hypodermic tubing carried in the outlet body to provide an inexpensive outlet passage with a minimum of contained volume.

    摘要翻译： 低惯量，快速响应，体积小的止回阀利用位于端对端对准中的两个主体构件。 阀体具有彼此密封接合的端面。 在一个端面中形成浅圆柱形室，并且承载非常薄的盘状阀闭合构件，其在相对于入口主体的表面的关闭位置和相对于出口主体的表面的打开位置之间漂浮。 封闭构件被释放以允许流体在其周围流动并且在出口体的表面处形成凹陷。 优选地，出口通道由不锈钢管形成，例如承载在出口本体中的皮下注射管，以提供具有最小容纳体积的便宜的出口通道。

    摘要： Spring means for urging a valve plate against a valve seat in an annular check valve, one disclosed each comprising at least two sprint plates adapted to engage one another in a valve, each plate having a plane portion out of which are bent arcuate spring portions of each of which the axial direction of bending, the peripheral direction, and the inner and outer radii are interrelated to substantially avoid the risk of spring portions of adjacent plates becoming entangled with one another in a valve.
