Abstract
Es wird ein Handsteuergeber (1) für eine hydraulische Steuerung, wobei wenigstens zwei, über ein gemeinsames mechanisches Bedienelement betätigbare Hydraulikventile (34, 35) mit Ventilkolben (24, 25) vorgesehen sind, an deren Ausgangsseite wenigstens zwei Verbrauchereinheiten über den Handsteuergeber manipulierbar angeschlossen sind. Um die Integration hydraulischer Zusatzfunktionen erleichtern zu können, sind die Ventilkolben (24, 25) mit dem Bedienelement (4) mechanisch derart gekoppelt sind, dass die Ventilkolben (24, 25) durch das Bedienelement (4) in wenigstens zwei Richtungen mit Kraft beaufschlagbar. There is a manual control transmitter (1) for a hydraulic control, wherein at least two, via a common mechanical control actuated hydraulic valves (34, 35) are provided with valve piston (24, 25), at the output side at least two consumer units are manipulably connected via the manual control , In order to facilitate the integration of additional hydraulic functions, the valve pistons (24, 25) are mechanically coupled to the operating element (4) such that the valve pistons (24, 25) can be acted upon by the operating element (4) in at least two directions.
