Piston compressor for medical use

Abstract

A volumetric compressor with one or more cylinders, comprising: at least one cylinder ( 2 ), provided with a suction opening ( 21 ) and a discharge opening ( 22 ) controlled by respective valves; a suction duct ( 3 ), connected to the suction opening ( 21 ); a discharge duct ( 4 ), connected to the discharge opening; a motor ( 5 ), provided with the possibility of varying its rotation speed; an adjustment valve ( 6 ), arranged along the suction duct ( 3 ), which is predisposed to vary the flow rate of the air directed to the suction opening.

1 . A volumetric compressor with one or more cylinders, comprising:
 at least one cylinder ( 2 ), provided with a suction opening ( 21 ) and a discharge opening ( 22 ) controlled by respective valves;   a suction duct ( 3 ), connected to the suction opening ( 21 );   a discharge duct ( 4 ), connected to the discharge opening;   a motor ( 5 ), provided with the possibility of varying its rotation speed;   characterised in that it comprises at least one adjustment valve ( 6 ), arranged along the suction duct ( 3 ), which is predisposed to vary the flow rate of the air directed to the suction opening.   
     
     
         2 . The compressor according to  claim 1 , comprising a control module ( 7 ), connected to the motor ( 5 ) and to the adjustment valve ( 6 ), which is predisposed to operate the adjustment valve ( 6 ) as a function of the rotation speed of the motor ( 5 ). 
     
     
         3 . The compressor according to  claim 2 , comprising a tank ( 8 ) connected to the suction opening ( 4 ) and provided with a pressure gauge ( 81 ) that is connected to the control module ( 7 ), wherein the control module ( 7 ) is predisposed to adjust the rotation speed of the motor ( 5 ) as a function of the pressure detected by the pressure gauge ( 81 ) inside the tank ( 8 ). 
     
     
         4 . The compressor according to  claim 2 , wherein the motor ( 5 ) is an electric motor provided with an inverter ( 51 ) connected to the control module ( 7 ). 
     
     
         5 . The compressor according to  claim 3 , wherein the motor ( 5 ) is an electric motor provided with an inverter ( 51 ) connected to the control module ( 7 ).
