摘要： A filter element assembly (10) includes an outer filter member (24) and an inner filter member (26). The filter assembly (10) is also provided with a support cap (44) having an outer ring (46), which is connected to the outer filter member (24), and an inner ring (48), which is connected to the inner filter member (26). The support cap (44) also includes a plurality of connecting members (50) connecting the outer ring (46) to the inner ring (48), which is positioned substantially within the outer ring (46). Each of the connecting members (50) is sized and shaped so as to allow the outer ring (46) and the inner ring (48) to move relative to each other.

摘要： A swing check valve (10), which is adapted for automatically inhibiting back flow of fluid from an outlet thereof to an inlet thereof, includes a clapper member (18) and a housing (12). The housing (12) has a first body portion (20), which includes its own valve seat (32) and its own mounting mechanism (56) adapted to removably mount the clapper member (18) therefrom when the first body portion (20) is positioned adjacent to the inlet of the valve (10). The housing (12) also has a second body portion (22), which includes its own valve seat (34) and its own mounting mechanism (64) adapted to removably mount the clapper member (18) therefrom when the second body portion (22) is positioned adjacent to the inlet of the valve (10). The first and second body portions (20, 22) are removably connected to each other in an end-to-end fashion and are interchangeable with each other, whereby each body portion may be utilized as a replacement for the other body portion.

摘要： An actuator for actuating a valve (16) from a first position to a second position includes a housing (14) and a rotatable stem (70) mounted within the housing and restricted from moving axially. The actuator also includes a non-rotatable plunger (94) engaging the stem such that the plunger moves axially in response to rotation of the stem, whereby the valve is actuated from the first position to the second position. The actuator is also provided with a non-rotatable indicator member (38), which is mounted within the housing and through which the stem extends. The indicator member engages the stem such that the indicator member moves axially in response to rotation of the stem. A viewing window (60, 64) is formed in a wall of the housing such that the indicator member can be seen through the window for indicating the first position and the second position of the valve.
摘要翻译：用于致动阀（16）从第一位置到第二位置的致动器包括壳体（14）和可旋转的杆（70），该杆可安装在壳体内并被轴向移动。致动器还包括接合杆的不可旋转的柱塞（94），使得柱塞响应于杆的旋转而轴向移动，由此阀从第一位置致动到第二位置。致动器还设置有不可旋转的指示器构件（38），其被安装在壳体内并且杆延伸穿过该构件。指示器构件接合杆，使得指示器构件响应于杆的旋转而轴向移动。观察窗（60,64）形成在壳体的壁中，使得可以通过窗口看到指示器构件以指示阀的第一位置和第二位置。
