<p>PURPOSE:To reduce vibration in a piping system and abnormal noise in a car by reducing discharging and suctioning pulsative motion in a reciprocative compressor. CONSTITUTION:In a compressor, a discharge chamber 3b or a suction chamber 3a are formed in a cylinder head 3 connected to an outer end of a cylinder block 1 through a valve plate 4. A sub-discharge chamber 16 or a sub-suction chamber is formed in an inner peripheral area compared to a bore 1a of the cylinder block 1. The sub-discharge chamber 16 or the sub-suction chamber is communicated with the discharge chamber 3b or the suction chamber through at least one through-hole 17 formed on the valve plate 4. In another phase, an outlet through-hole or an inlet through-hole formed on the sub-discharge chamber or the sub-suction chamber is communicated with a discharge passage or a suction passage.</p> |
