<p><P>PROBLEM TO BE SOLVED: To provide a scroll compressor having reduced pulsation for improving the following capability of intermediate pressure, and having a reduced dead volume. <P>SOLUTION: A back pressure chamber 63 is formed on the opposite side to the side of an end plate 26a of a movable scroll 26 where a lap 26b is formed. On the side of an end plate 24a of a fixed scroll 24 where the lap 26b is formed, at least one intermediate pressure groove 61 is formed which can be communicated with a compression chamber 40. Through the end plate 26a of the movable scroll 26 in the thickness direction, at least one through-hole 62 is formed which can be intermittently communicated with a space between the intermediate pressure groove 61 and the back pressure chamber 63. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
