Orbiting motor gear drive

A fluid pressure apparatus comprising:

• fixed body means;
• a first orbiting member disposed about said fixed body means, defining a plurality of outwardly-projecting teeth;
• a second orbiting member disposed about said fixed body means, defining a plurality of outwardly-projecting teeth equal in number to the teeth defined by the first member;
• means movably mounting the first and second orbiting members relative to the fixed body means for determining orbiting movement of the first and second orbiting members relative to the fixed body means;
• a first plurality of piston and cylinder means operatively interconnecting the fixed body means and first orbiting member;
• a second plurality of piston and cylinder means operatively interconnecting the fixed body means and second orbiting member;
• rotary body means defining a first plurality of inwardly-projecting teeth of a number greater than the number of teeth defined by the first orbiting member, the teeth of the orbiting member being adaptable for engagement with the first plurality of teeth of the rotary body means, and defining a second plurality of inwardly-projecting teeth of a number equal to the number of the first plurality of inwardly-projecting teeth defined by the rotary body means, the teeth of the second orbiting member being adaptable for engagement with the second plurality of teeth of the rotary body means, wherein the means movably mounting the first and second orbiting members relative to the fixed body means comprise a first plurality of crankshafts, each defining a main body portion rotatably mounted to the fixed body means, and an extending portion spaced from the axis of rotation of the main body portion, and to which the first orbiting member is rotatably mounted, and a second plurality of crankshafts, each defining a main body portion rotatably mounted to the fixed body means, and an extending portion spaced from the axis of rotation of the main body portion and to which the second orbiting member is rotatably mounted.
