Abstract
So as to decrease fluctuations in gas pressures acting on the external surface of an end plate by decreasing the area ratio of a high pressure chamber disposed on the outside of the end plate of a fixed scroll to a back pressure chamber, a scroll type compressor has one opening of the discharge port to the high pressure chamber provided in the end plate so as to coincide with the center of the spiral-shaped wrap.
