Abstract

A compressor includes: a cylinder; a piston arranged within the cylinder; an outer rotor type motor causing the piston to reciprocate within the cylinder; and a fan fixed to a rotor of an outer rotor type motor and facing at least a part of the cylinder.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A compressor comprising:
 a cylinder;   a piston arranged within the cylinder;   an outer rotor type motor causing the piston to reciprocate within the cylinder; and   a fan fixed to a rotor of the outer rotor type motor and facing at least a part of the cylinder.   
     
     
         2 . The compressor of  claim 1 , wherein the fan faces a chamber within the cylinder, and a capacity of the chamber increases and decreases in response to reciprocation of the piston. 
     
     
         3 . The compressor of  claim 1 , wherein a damping rate of vibration of the fan is greater than that of vibration of the rotor. 
     
     
         4 . The compressor of  claim 1 , wherein the fan is made of resin and the rotor is made of metal. 
     
     
         5 . The compressor of  claim 1 , wherein the fan is arranged in a radial direction of the rotor. 
     
     
         6 . A vacuum machine comprising:
 a cylinder;   a piston arranged within the cylinder;   an outer rotor type motor causing the piston to reciprocate within the cylinder; and   a fan fixed to a rotor of the outer rotor type motor and facing at least a part of the cylinder.   
     
     
         7 . The vacuum machine of  claim 6 , wherein the fan faces a chamber within the cylinder, and a capacity of the chamber increases and decreases in response to reciprocation of the piston. 
     
     
         8 . The vacuum machine of  claim 6 , wherein a damping rate of vibration of the fan is greater than that of vibration of the rotor. 
     
     
         9 . The vacuum machine of  claim 6 , wherein the fan is made of resin and the rotor is made of metal. 
     
     
         10 . The vacuum machine of  claim 6 , wherein the fan is arranged in a radial direction of the rotor.
