HYDROSTATIC STEERING MECHANISM Russian patent published in 2002 - IPC

FIELD: transport engineering; steering mechanisms of wheeled tractors and other self-propelled vehicles. SUBSTANCE: pressure space of housing in proposed steering mechanism is arranged from side opposite to orbital displacer and is placed in communication with inner space of spool. Drain space of housing arranged close to pressure space is connected with inner space of spool through bypass channels of spool and sleeves located in drain space zone. Distributing channels of sleeve and pressure channels of spool are located directly from side of orbital displacer. EFFECT: improved sealing, reduced pressure losses. 2 cl, 16 dwg
