ABSTRACT:
A low pressure container type rolling piston compressor which includes a compression element, a motor element, a rotary shaft with an eccentric portion driven by the motor element, a cylinder for receiving therein the eccentric portion of the rotary shaft, a rolling piston having an inner circumference to which the eccentric portion is fitted and an outer circumference which rolls along the inner wall surface of the cylinder, a vane having an end which is in contact with the outer circumference of the rolling piston to divide the inner space of the cylinder into a high pressure chamber and a low pressure chamber, a pair of bearing plates for closing both open ends of the cylinder, a sealing container housing the above-mentioned structural elements and storing at its lower part a lubricating oil wherein a pressure in the sealing container is the same as that in the low pressure chamber and wherein an oil supplying passage is formed in either one of the pair of bearing plates for closing both open ends of the cylinder so as to communicate the low pressure chamber with the inner space of the rolling piston rolling in the cylinder.
