A hydraulic torque converter comprises a housing (G), in which two vane cell stator/rotor sets (SR1, SR2) are arranged one behind the other. The two sets are in hydraulically communicating connection with one another. The rotors (6, 6′) are connected to a driveshaft (P) or an output shaft (M). The stators (7, 7′) are at a spacing from the associated rotors (6, 6′), and the spacing can be varied in at least one radial direction on the basis of pressure and/or centrifugal force, wherein means (75, 76, 77) are present in order to regulate the spacing from the associated rotor (6, 6′). This enables an inexpensive production of a continuously variable transmission which is, in addition, easy to regulate and has an optimized transmission of force.

The present invention discloses a hydraulic style motor having a first power input housing containing a first plurality of rotary or centrifugally driven pumps and associated valves, such that the pumps are driven in a determined stacked fashion by a powered input (or drive) shaft. A second power output housing contains at least one second rotary driven pump and associated valve, the second pumps rotatably engaging a second output (driven) shaft. A pressure resistant fluid line interconnects a manifold associated with the first housing with another manifold associated with the second housing so that the pressurized fluid generated by rotation of the input pumps in the input housing is communicated to the output housing to drive the output pumps to rotate the output (driven) shaft. A return line communicates with the output housing manifold, via each of the individual pump and valve subassemblies, for redirecting flow back to an input feed to the input housing.

A flexible binary pump system for a motor vehicle transmission includes a shaft, a first vane pump mounted on the shaft and having a first rotor with a first diameter and a first width and a second vane pump mounted on the shaft and having a second rotor with a second diameter and a second width. The first vane pump provides hydraulic fluid to the transmission at a first pressure, and the second vane pump provides hydraulic fluid to the transmission at a second pressure. The first diameter, first width, second diameter, and second width are selected to optimize power consumption of the binary pump system and hydraulic fluid budget for the transmission.
