Abstract:
A gravity fed drain assembly adapted for disposition in fluid communication with a point of fluid accumulation. The drain assembly includes a substantially rigid body of hollow construction including an inlet adapted for connection to a hose, tubing, or the like and an outlet downstream from the inlet. An insert plug is disposed within the drain body. The insert plug defines a tortured fluid flow path for transport of the liquid through the drain assembly. The circuitous flow path permits the continuous flow of liquid while damping sound transmission in the reverse direction.
Abstract:
Embodiments of a noise reduction system for use in heating, ventilating, air conditioning, and refrigeration (HVACR) systems are provided. The noise reduction system may include a barrier to be placed over an air inlet of an HVACR base unit. The barrier, consisting of two rows of equally spaced structures, may permit the passage of air therethrough while preventing the escape of noise from the base unit. The noise reduction system may also include one or more resonance chambers placed atop the base unit and a structure placed adjacent the base unit. Noise coming from the base unit may be redirected by the structure toward the resonance chambers, which are configured to attenuate the noise.
Abstract:
An isolating clip (10) for holding tubes, fluid lines and the like is provided with a rigid outer shell (12) and a flexible insert (14). The insert (14) includes an outer body (60) and a tube seat suspended from the outer body (60) by flexible connectors (82). Bumpers (92) can be provided in the space between the outer body (60) and tube seat (66) to limit deflection of the tube seat (66).
Abstract:
Certain embodiments of the present invention provide a vibration-dampening clip assembly (10) configured to dampen vibrations between a tube member and a structure. The clip assembly (10) may include a base (12) configured to secure to a surface of the structure, at least one first spring member (36), and at least one second spring member (42). A tube retention area (50) is defined between the at least one first spring member (36) and the at least one second spring member (42). The tube retention area (50) is suspended away from the base (12). The at least one first spring member (36) and the at least one second spring member (42) are configured to absorb vibratory energy generated by or within the tube member.
