Abstract
A noise-suppressor for fluid-borne noises in a hydraulic system comprises a cylindrical shaped housing consisting of a pair of cup-shaped end caps and a tubular center section connected therebetween such that the joint between the section and end caps is spaced from the end of the housing. The housing includes fins on the outer surface for radiating heat therefrom. An inertance tube is disposed within the housing coaxially thereof and communicating directly with the outlet thereof which in turn is coaxial with an inlet thereto.
Claims5
A segmented noise-suppressor for fluid-borne noises in hydraulic systems, comprising:
- a pair of first segments including cup-shaped unitary end caps, each having a flat end and a tubular wall extending therefrom;
- at least one second segment including one tubular center section joining said end caps at joints spaced from the flat ends thereof by said tubular walls thereof for defining an enlarged chamber with said caps at the ends thereof and aligned coaxially with one another;
- one of said caps having means defining an inlet coaxial thereof;
- the other of said caps having an outlet coaxial thereof and
- an internal inertence tube coaxial with said inlet and said outlet and communicating with said outlet.
