Abstract
A compressor includes a cylinder block including cylinder bores and pistons within the cylinder bores. A front housing opposes a first cylinder block end face to form a crank chamber accommodating a piston driving mechanism. A valve plate opposes a second cylinder block end face and includes suction and discharge holes. A rear housing includes suction and discharge chambers and opposes the second cylinder block end face with the valve plate there between. Strap-shaped suction valves on the valve plate end face oppose the cylinder block, thereby opening and closing the suction holes at tip portions. Discharge valves on the valve plate end face oppose the rear housing to open and close the discharge holes. Through-bolts join the front housing, the crank chamber, the cylinder block, the valve plate, and the rear housing. The valve plate includes grooves extending from holes accommodating the through-bolts to portions abutting the suction valves.
