Compressor device

Abstract

Provided is a compressor device, including: a casing in which a motor (armature and movable element) is housed; an output shaft, which projects from the casing, and is configured to be reciprocated by drive of the motor; a piston provided to a projecting end of the output shaft; a cylinder in which the piston is slidably provided to form a compression chamber; and a cylinder head connected to the cylinder. A tubular shield corresponding to a shielding portion configured to cover the cylinder in such a manner as to be separate from the cylinder in a radial direction of the cylinder is provided on an outer periphery side of the cylinder. The cylinder, the cylinder head, and the tubular shield are coupled to be integrated.

1 . A compressor device, comprising:
 a casing in which a motor is housed;   an output shaft, which projects from the casing, and is configured to be reciprocated by drive of the motor;   a piston provided to a projecting end of the output shaft;   a cylinder in which the piston is slidably provided to form a compression chamber; and   a cylinder head connected to the cylinder,   wherein a shielding portion configured to cover the cylinder in such a manner as to be separate from the cylinder in a radial direction of the cylinder is provided on an outer periphery side of the cylinder,   wherein the cylinder, the cylinder head, and the shielding portion are coupled to be integrated, and   wherein the cylinder and the shielding portion are connected to each other with a plurality of ribs.   
     
     
         2 . (canceled) 
     
     
         3 . The compressor device according to  claim 1 , further comprising:
 an air dryer, which is connected to the cylinder head, and is loaded with a desiccant; and   solenoid valves configured to control supply and exhaust of a compressed air to and from the air dryer,   wherein the solenoid valves are located on a radially outer side of the cylinder, and are fixed in a sandwiched state between the casing and the cylinder head, and   wherein the shielding portion is provided on an outer side of the solenoid valves.   
     
     
         4 . The compressor device according to  claim 1 , wherein a surface area of the shielding portion is larger than a surface area of the cylinder. 
     
     
         5 . The compressor device according to  claim 1 , wherein a surface area of the cylinder head is larger than a surface area of the cylinder. 
     
     
         6 . The compressor device according to  claim 3 , wherein the shielding portion has opening portions formed so that the solenoid valves are exposed to an atmosphere. 
     
     
         7 . The compressor device according to  claim 3 , wherein a surface area of the shielding portion is larger than a surface area of the cylinder. 
     
     
         8 . The compressor device according to  claim 3 , wherein a surface area of the cylinder head is larger than a surface area of the cylinder. 
     
     
         9 . The compressor device according to  claim 3 , wherein a valve housing space is defined by the cylinder, the shielding portion and the ribs, and
 wherein a solenoid valve is disposed in the valve housing space.
