Patent DE-2344629-A1 (DE)
Title: Variable drive unit with twin output - has hydraulic pump-motor combination to regulate output distribution
Inventor: SLOTOSCH JOACHIM
IPC: F16H43/00
Filed: 1973-09-05
Abstract: The annulus of an epicyclic gear is connected to a motor output shaft. The sun wheel is located on the drive shaft of a hydraulic pump and the shaft of the planet wheel arm is linked up with the shaft of a hydraulic motor. When starting the drive, the annulus drives the sun wheel with the planet wheel arm stationary. The output shaft is thus driven through the hydraulic pump and motor. As the speed of the hydraulic motor and thus the planet wheel arm increases, the power output which reaches the pump decreases. Hence a condition is reached where the principal share of the output is transmitted through the mechanical elements. By selecting hydraulic elements with a high efficiency at low revolutions and that of mechanical elements at high revolutions an improved overall efficiency is obtained.

Title: Load insensitive flow regulator with compensating spool - sliding spool reacts to pressure difference and spring bias force
Inventor: SANDAU HARTMUT
IPC: G05D7/01
Filed: 1974-05-15
Abstract: A flow regulating valve has a built-in compensating stage to provide insensitivity to output loading conditions. An input port (13) transmits flow to an orifice (18) formed by a needle (16) and a hole (17) in a preset disc (16). The disc is initially set by moving a bush (15) with a screw thread adjuster (19). The needle is part of a sliding spool (23) that is spring biased (27) against a fixed disc (28). A bleed passage (33) transmits supply pressure to the opposite end (32) of the spool. In this way the pressure difference created by the orifice is used to balance the spring force. If the output (12) load increases the pressure difference decreases and the orifice area increases.
