Rotary piston cylinder device with radially extending cylinder chambers intersecting at a rotary axis

A rotary cylinder apparatus comprising:

• a rotary cylinder member having a cylinder chamber formed thereto so as to pass through a rotary shaft center and rotating around said rotary shaft center, said rotary cylinder member is rotatably supported by a bearing plate, said bearing plate is configured to be adjustable by an adjusting pushing screw and an adjusting drawing screw;
• a piston demonstrating reciprocating linear motion in surface contact with inside of said cylinder chambers;
• and
• a piston holding member holding said piston and rotating around a rotation center eccentric from said rotary shaft center of said rotary cylinder member;
• and
• a casing rotatably supporting and accommodating said rotary cylinder member and said piston holding member and having at least one inlet for a fluid and at least one outlet for the fluid, wherein said piston is rotatably held at a position away from said rotation center of said piston holding member by a fixed distance.
