Positive displacement machine, compressor, cooling apparatus, and electronic equipment

A positive displacement machine comprising:

• a housing including a tubular guide part in which a pressure chamber is provided;
• a slide member including a piston disposed in the guide part, the slide member sliding in a first direction;
• a coupling member coupled to the slide member and extending in a second direction intersecting the first direction;
• a first rotating member coupled to one end portion of the coupling member and configured to rotate centering on a first rotation axis extending in the second direction;
• a second rotating member coupled to another end of the coupling member and configured to rotate, centering on a second rotation axis extending along the second direction, in an opposite direction of a rotating direction of the first rotating member;
• a first motor including a first rotor coupled to the first rotating member and configured to rotate centering on the first rotation axis, and a first stator disposed on an outer side of the first rotor when viewed along the first rotation axis;
• and
• a second motor including a second rotor coupled to the second rotating member and configured to rotate centering on the second rotation axis, and a second stator disposed on an outer side of the second rotor when viewed along the second rotation axis, wherein
• the first motor includes a first adjusting mechanism configured to adjust an angle of the first stator with respect to the first rotor, the angle being centered on the first rotation axis.
