Noise reducing silencer with a spirally shaped tube for a compressor

Abstract

A silencer for a compressor, the silencer including a housing, a spirally shaped silencer tube provided in the housing and having an inlet and an outlet, a connecting element connected to the silencer core to connect the outlet of the silencer core to an inlet of a compressor. The silencer tube is provided to reduce noise during operation of the compressor.

What is claimed is: 
     
         1 . A silencer for a compressor, said silencer comprising:
 a housing;   a spirally shaped silencer tube provided in the housing and having an inlet and an outlet; and   a connecting element configured to connect the outlet of the spirally shaped silencer tube to an air inlet of the compressor.   
     
     
         2 . The silencer according to  claim 1 , wherein the spirally shaped tube is configured to reduce noise generated from air entering the compressor during operation. 
     
     
         3 . The silencer according to  claim 1 , wherein the connecting element is provided along an inner side of windings of the spirally shaped silencer tube. 
     
     
         4 . The silencer according to  claim 1 , further comprising a filter element and a filter screen configured in a way to support the filter element, wherein said filter element and filter screen are provided circumferentially around an outer side of the spirally shaped silencer tube. 
     
     
         5 . The silencer according to  claim 1 , wherein the spirally shaped silencer tube comprises composite material. 
     
     
         6 . The silencer according to  claim 1 , wherein the housing comprises a base and a cover for enclosing the housing, and wherein said housing comprises at least one opening for an inlet airflow. 
     
     
         7 . The silencer according to  claim 2 , wherein the spirally shaped silencer tube comprises at least two windings. 
     
     
         8 . The silencer according to  claim 1 , wherein the spirally shaped silence tube is coated with a sound absorbing material. 
     
     
         9 . A compressor installation comprising:
 a motor;   a compressor element;   and a silencer connected to an air inlet of the compressor element, said silencer comprising a housing, a spirally shaped silencer tube provided in the housing, said silencer tube having an inlet and an outlet, and a connecting element that connects the outlet of the silencer tube to the air inlet of the compressor element,   wherein the silencer tube is configured in a way to reduce noise generated from a gas or gasses entering into the compressor during operation.   
     
     
         10 . The compressor installation according to  claim 9 , wherein the compressor is a reciprocating compressor, and the gas is air.
