In a scroll-type fluid displacement compression apparatus, the structure, named as a two-way gas suction and an oil-gas mixed lubrication plate thrust bearing and a one-sided Oldhams ring, makes the mixture of oil and gas, which is entered into the apparatus, flowing in two directions such that most of the working gas media is changed the flowing direction and sucked into the suction chamber of the scroll members directly while most of lubrication oil-fog flows on the sliding plate thrust bearing through certain passages and lubricates it well. The supporting area of the sliding plate thrust bearing can be enlarged due to the structure of the one-sided Oldhams ring. As a result, the displacement scroll-type fluid compression apparatus can be used in a wide variable range of speed and variable angle positions.
