Elektro-hydraulisches Steuerventil

摘要

This invention concerns an electrohydraulic control device which contains at least one 3/2-way valve (2) which is switched by an electromagnet (3) connected to an intrinsically safe power supply. The components of the 3/2-way valve (2) are arranged in a valve cartridge (18) which is inserted along the same axis into the valve housing (1) and whose clearance from the electromagnet (3) can be adjusted. The switch ram (12) of the electromagnet (3) transmits the switching action via a shock absorber (4) under spring tension to the closing element (24, 30) of the 3/2-way valve (2).
