Latest Patents

Parthuisot's latest patents include a hydrodynamic torque converter with bridging means. This innovative converter is designed for automatic transmissions and provides multiple gear ratios. It features a mechanism that bridges the input and output shafts, allowing for efficient operation. The hydraulic fluid is supplied through a hollow transmission shaft, which penetrates into the converter's inner space via a gaged orifice. The control chamber's outlet is closed by a solenoid valve, ensuring that the pressure in the converter's inner space matches that of the control chamber. Additionally, spring means are included to urge the control piston to its release position during torque converter operation.

Another significant patent is the device controlling the bridging of a hydrodynamic torque converter. This control device utilizes a moving slide acted upon by a return spring, which uncovers an orifice to allow hydraulic fluid to feed into a release chamber. This action moves the control piston, effectively removing the bridging between the input impeller and the output turbine of the converter. The bridging is actuated by an electrohydraulic transducer, which is controlled by an electronic device that responds to input and output speeds detected by sensors.
