ELECTROHYDRAULIC PILOT CONTROL WITH TWO PRESSURE CONTROL VALVES

摘要

Electrohydraulic pilot control 1 for a hydraulic unit which can be a proportional directional valve, a variable displacement pump or a servomotor, which electrohydraulic pilot control 1 contains two proportionally acting pressure control valves 3 and is provided with a control block 2 which receives the hydraulic valve parts 4 in bores and to which the associated proportional magnets are flange-connected, wherein the proportional magnets have a common electrical plug-in connection 5, and wherein the two proportional magnets 3 are joined together by injection-moulding encapsulation with plastic to form an assembly which is fastened to the control block 2 and in the process is oriented precisely relative to the valve components 4 which are received in the control block, by means of positioning aids which act perpendicularly with respect to the movement direction of the armatures.
