摘要:
A scroll compressor is provided with a two groups of commmunication ports formed in and extending through an end plate of a stationary scroll member. Each group includes two or more communication ports. A lead valve is associated with each of the two groups of communication ports and is operable by a pressure differential in between an associated compression chamber and the discharge chamber to communicate the communication ports of the group to the discharge chamber to prevent the occurrence of over-compression in the compression chamber.
