<p><P>PROBLEM TO BE SOLVED: To enlarge the opening area of a suction hole as much as possible to improve compression efficiency. <P>SOLUTION: This compressor is provided with a cylinder block 2 having a cylinder bore 3, a piston 27 stored in the cylinder bore so as to reciprocate forward and backward, a rear housing 6 joined with a rear end face of the cylinder block to form a suction chamber 7 and a discharge chamber 8, a valve plate 9 provided between the rear housing and the cylinder block, a suction hole 28 provided in the valve plate to communicate the cylinder bore and the suction chamber mutually, and a discharge hole 30 provided in the valve plate to communicate the cylinder bore and the discharge chamber mutually. Refrigerant gas sucked into the cylinder bore through the suction hole is compressed by the piston and is discharged into the discharge chamber through the discharge hole. The suction hole is formed to have a long hole shape. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
