Rotary piston machine having engaging cycloidal gears

A rotary piston machine, which functions as a pump, compressor or engine, having a housing which includes an inlet and an outlet which include control conduits (9),

• a conical gear (3, 23, 42, 54) supported both axially and radially and connected to a driving or driven apparatus (11, 18, 43), said conical gear including gear teeth (5) on opposite sides thereof,
• first and second gears having a radial sealing diameter, each of said first and second gears including gear teeth (4) on at least one side,
• means for a radial sealing and guidance of the first and second gears in said housing (7, 17, 38),
• an inclination of an axis of rotation (IV) of each of the first and second gears relative to an axis of rotation (v) of said conical gear in which the inclination of the axis of each of said first and second gears relative to the axis of said conical gear is (.alpha.),
• work chambers (8, 26, 58) are located between the gear teeth (4) on each of said first and second gears and the gear teeth (5) on opposite sides of said conical gear (3),
• a volume of the work chambers (8, 26, 58) alternatingly increases and decreases during rotation of said first and second gears and said conical gear up to a predetermined value, and
• a plurality of flanks (14) of said teeth (4) on said first and second gears have a positive engagement, with a plurality of tooth cogs (13, 35) of the teeth (5) on said conical gear to define said work chambers,
• the teeth of the first and second gears intermesh with the teeth on the conical gear and are embodied as a cycloidal surface with a cycloidal development of an intermeshing surface (14, 36, 57),
• that the teeth (5) of the conical gear meshingly cooperate with the cycloidal surface of each of said first and second gears and have a difference of one tooth in the number of teeth relative to the cycloidal surfaces and said conical gear (3) serves as a control part (3, 23, 46, 54, 59),
• that said conical gear (3, 23, 4, 54, 59) controls said control conduits (9) present in the housing (7, 17, 38), and
• that a plurality of tooth cogs (13, 35) of said conical gear (3, 23, 46, 54, 59) rotate relative to the cycloidal surface, and revolve along the plurality of flanks (14, 36, 44) of the teeth (4) of the cycloidal surface.
