Japanese Patent JP4292676
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce noise generated when a large quantity of refrigerant flows through a passage hole. SOLUTION: Since the first passage 43a of a two-phase refrigerant passage 43 on the low pressure side is provided with a member 60 projecting toward a second passage 43b, significant pressure variation of refrigerant immediately after passing through a throttle passage hole 48 is damped when the refrigerant flows through the projecting member 60. Noise can be reduced by passing refrigerant through a block joint after pressure variation thereof is damped thereby suppressing vibration of the block joint.
