It is further used as the improvement of technical solution of the present invention, when the inner wall of access road is convex equipped with more than two throttlings
When rising, the throttling protrusion is arranged on the varying cross-section of access road.
It is further used as the improvement of technical solution of the present invention, the throttling protrusion is directly rushed on inlet tube by forming punching head
It presses.
It is further used as the improvement of technical solution of the present invention, the throttling protrusion is using screw threads for fastening, welding, riveting or glues
It is connected on the inner wall of access road.
It is further used as the improvement of technical solution of the present invention, the height of each throttling protrusion is h, the internal diameter of inlet tube
For D, h≤0.25D.
A kind of refrigeration compressor, including refrigeration compressor ontology and above-mentioned muffler, the muffler are set
In the exhaust ports of refrigeration compressor ontology.
Beneficial effects of the present invention：The present invention provides a kind of lower resistance throttling schemes, in muffler inlet channel
Wall is equipped with the throttling boss of throttling action, plays the role of part throttle, influences very little to the circulation area of entire exhaust channel,
It can be ignored.Compressor low-pressure starting ability is good, and high cooling efficiency is simple in structure, increases part without additional.It is come rising
While preferable throttling action, the pressure change and pulsating quantity of entire exhaust channel can be reduced, performance boost and noise are dropped
It is low to have remarkable effect.
