Patent DE-19913276-A1 (DE)
Inventor: HABERMANN HEINZ
IPC: F15B13/042
Filed: 1999-03-24
Abstract: The invention relates to a hydraulic pilot control comprising two control outputs (96, 97) which can be impinged upon by a control pressure and a hydraulic pilot control device which has a lever (81) that can be moved from a neutral position in a first and second direction. The hydraulic pilot control also comprises a pressure valve (69) which can be adjusted by displacing the lever from the neutral position.
