 the cylinder block includes a body portion, a cylindrical portion extending laterally from a circumference of the body portion to define the compression chamber therein, and a flange portion provided at a distal end of the cylindrical portion opposite the body portion,    the supporting of the cylinder block is accomplished as a surface of the flange portion facing the cylindrical portion is supported on a supporting surface of the assembling jig, and    the block guide holes are provided at the flange portion.    
   
   
       3 . The method according to  claim 2 , wherein: 
 the cylinder head includes a refrigerant suction chamber and a refrigerant discharge chamber, the refrigerant section chamber being separated from the refrigerant discharge chamber, and    the valve device includes, 
 a valve plate having a suction hole configured to enable communication between the compression chamber and the refrigerant suction chamber, a discharge hole enabling the compression chamber and the refrigerant discharge chamber, and a discharge valve to open or close the discharge hole,  
 a suction valve interposed between the valve plate and the flange portion to open or close the suction hole,  
 a first gasket interposed between the suction valve and the flange portion, and  
 a second gasket interposed between the valve plate and the cylinder head, and  
 the valve guide holes are provided in the valve device to correspond to the block guide holes.  
   
   
   
       4 . A cylinder assembly for a compressor, comprising: 
 a cylinder block having a compression chamber defined therein;    a cylinder head coupled to the cylinder block and configured to seal the compression chamber;    and a valve device interposed between the cylinder block and the cylinder head and configured to control the inflow and outflow of refrigerant into and out of the compression chamber,    wherein the valve device and the cylinder head are positioned to be aligned with the cylinder block when the cylinder block is supported on an assembling jig,    wherein a plurality of block guide holes and a plurality of valve guide holes are perforated through a portion of the cylinder block and the valve device, respectively, to allow guide pins to be fastened therethrough, and    wherein a plurality of head guide recesses are formed at a surface of the cylinder head to be coupled to the valve device.    
   
   
       5 . The assembly according to  claim 4 , wherein: 
 the cylinder block includes a body portion, a cylindrical portion extending laterally from a circumference of the body portion to define a compression chamber therein, and a flange portion provided at a distal end of the cylindrical portion opposite to the body portion, and    the plurality of block guide holes are provided at the flange portion.    
   
   
       6 . A method for assembling a cylinder assembly, the method comprising: 
 fastening at least one guide pin through at least one guide hole provided at a cylinder block;    aligning at least one of a valve device and a cylinder head with the cylinder block by fastening at least one guide pin through at least one guide portion provided at each of the valve device and the cylinder head;    securing the cylinder block to at least one of the valve device and the cylinder head; and    removing the at least one guide pin.    
   
   
       7 . The method according to  claim 6 , wherein the at least one guide pin includes a plurality of guide pins.  
   
   
       8 . The method according to  claim 7 , wherein the at least one guide pin is provided at an assembling jig.  
   
   
       9 . The method according to  claim 6 , wherein the at least one guide pin is provided at an assembling jig.  
   
   
       10 . The method according to  claim 6 , wherein the at least one guide portion includes at least one of a valve guide hole and a head guide recess.  
   
   
       11 . An apparatus for assembling a cylinder assembly, the apparatus comprising: 
 means for fastening at least one guide pin through at least one guide hole provided at a cylinder block;    means for aligning at least one of a valve device and a cylinder head with the cylinder block by fastening at least one guide pin through at least one guide portion provided at each of the valve device and the cylinder head;    means for securing the cylinder block to at least one of the valve device and the cylinder head; and    means for removing the at least one guide pin.
