Hydrostatic torque converter

TL;DR: In this article, a hydrostatic torque converter with a joint housing, an axial piston-pump and a motor part with variable feeding and absorption-volume, respectively, is described.

Abstract: A hydrostatic torque converter which comprises a joint housing, an axial piston-pump to constitute a pump part and an axial piston-motor to constitute a motor part with variable feedingand absorption-volume, respectively, within the joint housing, in particular for the use as a drive controlled in accordance with the output requirement for the drive of a generator operating with a comparatively high number of revolutions variable at a ratio of about 1:5 by means of an internal combustion engine with an essentially lower number of revolutions variable in turn at a ratio of about 1:6. The volume ratio of the pump part and the motor part of the converter amounts to about more than 1:1. The pump part and the motor part have swinging bodies rotatably mounted in the housing. A servo setting cylinder, a piston reciprocating therein, and a rod mechanism are coupled together. The swinging bodies are controlled by the servo cylinder with the piston by means of said mechanism such, that the output speed of the converter corresponds with the desired generator driving output which is maintained by variation of the feeding quantity of the axial piston-pump and for the absorption quantity of the axial piston-motor independent from the input speed of the converter.
