Ring disk reciprocating power conversion device

A ring disk reciprocating power conversion device, comprising:

• a planetary gear set provided with a solar wheel and a plurality of planet wheels engaged in the periphery of the solar wheel;
• and
• at least one eccentric control panel set, comprising:
• a rotary disk pivoted on a center axle of the solar wheel and arranged opposite to the planetary gear set, being able to receive guiding from rotation of the planet wheel, forcing the rotary disk to do a reciprocating movement in limited amplitude;
• an annular chamber, formed in a periphery of the rotary disk, the annular chamber accommodating a pressure forming medium, wherein the medium is oil;
• a plurality of separation parts, separating the annular chamber to form a plurality of variable volume chambers;
• and
• a plurality of spacers having equal quantities as that of the plurality of variable volume chambers, movably arranged in the periphery of the rotary disk, and being able to enter the plurality of variable volume chambers to press or draw the medium to regulate and stop the rotation of the planet wheel, and being able to leave the plurality of variable volume chambers to release the planet wheel to rotate.
