摘要： PROBLEM TO BE SOLVED: To reduce the quantity of the oil flowed into a refrigerating cycle by forming a path by way of the oil in an oil reservoir portion, in a path from a compressing operational portion to a discharge port as an outlet to the outside of a compressor. SOLUTION: When a motor 19 is rotated and a revolving scroll member 3 is revolved through a shaft 12, the gas in a suction chamber 60 formed on an outer peripheral part of an area where both scroll laps 2b, 3b are engaged, is confined in a compression chamber 6 formed between both scroll members 2, 3 to be compressed, and then discharged into a fixed back chamber 61. The oil 69 stored at a lower part of a motor chamber 62 and the fixed back chamber 61 is pressed downward by the increase of the pressure of the compressed gas, to be flowed into an oil storing chamber 80 through a lower passage port 18a, and the oil face at the oil storing chamber 80 side is risen. The gas risen to the surface of the stored oil 69 in the oil, storing chamber 80 is passed through an oil-drops removing portion formed by a porous body, and then discharged to the outside of the compressor from a discharge port formed by a discharge pipe 55.

摘要： PURPOSE:To perform stable feedback control by detecting both the position of a shaft and an electric current which flows across an electromagnet and making calculation by the use of a digital circuit. CONSTITUTION:ON-OFF operation of each of switches SW1 and SW2 is performed via solenoid driving circuits 14 and 15 in response to an output signal of a micro-processor 13. The position of a shaft 1 is detected by a displacement gauge 16 and then input to the mircro-processor 13 via an A/D converter 17. Values of electric currents across coils 4 and 6 are also input to the micro- processor 13 via the A/D converter 17. The current across the coils of the electromagnet is detected and the value of the current across the coils are restricted in accordance with a load which is applied to the shaft, whereby enabling stable feedback control.

摘要： PURPOSE: To improve the resonance characteristic of vibration system by providing members for regulating the volume of cylinder spaces in a pair of gas spring elements to be coupled to the opposite sides of vibration motor thereby setting the gas spring constant to proper level.
CONSTITUTION: In a vibration compressor, a pair of gas spring elements are coupled to the opposite sides of vibration motor comprised of a stator 1 and a vibration chip 2 while a pair of compression elements are coupled to the outside of each element. The gas spring element is comprised of a piston 4 arranged through rods 3 (3a, 3b) to the opposite sides of vibration chip 2 and a cylinder 5 surrounding said piston 4 while the compression element is comprised of a piston 8 to be fixed to the rod 3 and a surrounding cylinder 9. Here, the chambers 6a, 6b and 7a, 7b where compression and expansion will occur synchronously with the cylinder 5 are communicated respectively through paths 20a, 20b. While regulation seats 21a, 21b concerning with the volume regulation member are provided in respective chamber 6a, 7b.
