Abstract
The gas flow direction and the noise generation direction are in opposite directions in the suction muffler. The flow path in the muffler has a number of changes in direction and the flow path cross section decreases at each change of direction in the direction of flow.
Claims15
A muffler and a suction pipe with an inlet and a cross sectional area, said muffler coacting with said suction pipe to define a flow path having an inlet and a plurality of changes in flow direction and terminating at said inlet of said suction pipe with said flow path having a cross sectional area which serialy reduces at each change in flow direction in the direction of flow.
A chiller including a cooler and a compressor with a suction pipe having an inlet and extending into said cooler, a muffler in said cooler and coacting with said suction pipe to define a fluid path extending from the interior of said cooler to said inlet of said suction pipe, and having a plurality of changes of direction, said suction pipe having a cross sectional area and said fluid path having an increased cross sectional area at each change of direction when starting at said inlet of said suction pipe and going towards the interior of said cooler.
A muffler and a suction pipe with an inlet and a cross sectional area, said muffler being spaced from and coacting with said suction pipe to define a flow path through the space between said suction pipe and said muffler with said flow path having an inlet and a plurality of changes in flow direction and terminating at said inlet of said suction pipe with said flow path having a cross sectional area which reduces at each change in flow direction.
