ABSTRACT:
An apparatus for coupling a fluid-responsive device with a valve which includes an actuator. The valve responds to actuation of the actuator by opening a fluid path within the valve in response to the actuator being in a first position and by closing the fluid path in response to the actuator being in a second position. The apparatus comprises a coupler having a first engagement structure for fixedly engaging the fluid-responsive device at a first end, a second engagement structure for fixedly engaging the valve at a second end, and a passage between the first end and the second end. The apparatus further comprises a damper fixedly situated substantially blocking the passage. The damper is generally capillarized to establish a network of capillary vias through the damper. Still further, the apparatus comprises an extension formed integrally with the damper and proportioned to move the actuator when the valve is fixedly engaged at the second end.
