Air compressor

Abstract

An air compressor including: a motor; a compression mechanism that is configured to be driven by the motor; a tank unit that includes an air tank configured to store therein compressed air generated by the compression mechanism and to which the motor is fixed; an elastic member via which the compression mechanism is coupled to the tank unit; and a rotation transfer member that is configured to transfer a rotational force of the motor to the compression mechanism even when a shaft center of a rotary shaft of the motor and a shaft center of a rotary shaft of the compression mechanism deviate from each other.

1 . An air compressor comprising:
 a motor;   a compression mechanism that is configured to be driven by the motor;   a tank unit that includes an air tank configured to store therein compressed air generated by the compression mechanism and to which the motor is fixed;   an elastic member via which the compression mechanism is coupled to the tank unit; and   a rotation transfer member that is configured to transfer a rotational force of the motor to the compression mechanism even when a shaft center of a rotary shaft of the motor and a shaft center of a rotary shaft of the compression mechanism deviate from each other.   
     
     
         2 . The air compressor according to  claim 1 ,
 wherein the rotation transfer member is a flexible coupling or an universal joint.   
     
     
         3 . The air compressor according to  claim 1 , further comprising a piping unit configured to deliver the compressed air generated by the compression mechanism to the air tank,
 wherein the piping unit has elasticity.   
     
     
         4 . The air compressor according to  claim 3 ,
 wherein the piping unit is a flexible tube.   
     
     
         5 . The air compressor according to  claim 1 ,
 wherein the motor is not directly coupled to the compression mechanism except for transferring of a driving force.   
     
     
         6 . The air compressor according to  claim 1 ,
 wherein the motor is fixed to the tank unit without via an elastic member.   
     
     
         7 . The air compressor according to  claim 1 ,
 wherein the tank unit includes a frame that supports the air tank, and the compression mechanism is coupled to the frame.   
     
     
         8 . The air compressor according to  claim 1 ,
 wherein the compression mechanism is a reciprocating compression mechanism.
