ABSTRACT:
A scroll-type compressor which is particularly suited for use as a refrigerant compressor has a biasing chamber for pressure biasing the non-orbiting scroll to augment tip sealing. The biasing chamber communicates with the fluid pockets of the compressor through a biasing passage extending through the end plate of the non-orbiting scroll. The biasing passage is in fluid communication with the innermost fluid pocket during only a portion of each of the cycles of orbiting motion and in fluid communication with an intermediate fluid pocket during another portion of the cycles orbiting motion.
