Abstract:
A compressor comprising:a housing having a compression chamber and a suction chamber defined adjacent to each other in said housing; a movable member associated with said compression chamber so that a coolant gas is sucked from the suction chamber into the compression chamber, compressed in the compression chamber and discharged from the compression chamber; and a suction muffler structure, said suction muffler structure comprising: a muffler chamber provided between the suction chamber and an external coolant circuit; a suction passage connecting the muffler chamber to the suction chamber, said suction passage having an inlet from said muffler chamber; and said muffler chamber having a liquid-storage space formed in a region in the muffler chamber lower than said inlet; wherein a through-hole formed in said muffler chamber receives a flow of coolant from said external coolant circuit; wherein said through-hole is positioned at the same level or higher in the muffler chamber than said inlet; wherein said compressor is positioned at a lower position in an engine room than said external coolant circuit, such that when the compressor is stopped, any liquid coolant in said external coolant circuit flows into said liquid storage space of said compressor due to the height difference thereby reducing any vibration and noise that may accompany liquid compression.
