Title: Scroll compressor
Inventor: SUEFUJI KAZUTAKA
IPC: F04C28/00
Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor capable of preventing a leakage of gas even when a gas having a higher pressure than an atmospheric pressure is compressed. SOLUTION: A suction pressure adjustment valve 15 is connected to a suction port 11 of a stationary scroll 2 through flowing-in piping. A contact seal 25 positioned between an outer periphery and a ring receiver 2D of the stationary scroll 2 is provided on the outer periphery side of a mirror plate 6A of the rotary scroll 5 and a lip part of this contact seal 25 is contacted in the state that it is urged to the stationary scroll 2 by a spring member. Since the suction pressure adjustment valve 15 is only opened when a suction chamber 12 becomes a predetermined pressure of an atmospheric pressure degree, the suction port 11 can be retained to an approximately atmospheric pressure even when a gas having a higher pressure than an atmospheric pressure is fed. Thereby, a sealability by the contact seal 25 is enhanced and a gas can be retained in the suction chamber 12.
