Embodiment Construction

[0017] Now refer to figure 1 Be explained.

[0018] A circuit arrangement 10, also called a valve control device 10, controls a movable contact 11 of a high-voltage power switch 12 by means of a piston-cylinder device 13 in which a piston 15 is movably arranged in a cylinder 14 in which The side of the piston defining a chamber 16 below the piston 15 is connected to a piston rod 17 which is coupled with a movable contact 11 of a switch 12 . On the opposite side of the piston 15, there is a chamber 18 above the piston 15, wherein the piston surface defining the chamber 18 is larger than the piston surface defining the chamber 16, because the piston surface at the chamber 16 is according to the transverse direction of the piston rod 17. cross section is reduced. When hydraulic fluid is now pumped into the chambers 16 and 18 above and below the piston 15 , the piston 15 moves in the direction P1 and the piston rod 17 moves in the direction of the moving contact piece 11 . When...

Abstract

Exemplary embodiments relate to a valve arrangement for actuating a piston cylinder arrangement, that includes a pilot control valve arrangement and a main control valve arrangement, wherein both the pilot control and main control valve arrangement include a 3 / 2-way valve as a pilot control valve and as a main control valve. Each valve has a control-pressure, high-pressure, and low-pressure connection. Said connections are connected to each other such that the main control valve is controlled via the control-pressure connection of the pilot control valve and the pressures on the control-pressure connection of the pilot control valve and the pressures on the control-pressure connection and on the high-pressure connection of both valves, are statically inverted relative to each other. The 3 / 2-way valves are designed as seat valves and are only hydraulically connected to each other.

Description

technical field [0001] The invention relates to a valve control device with a preset valve device and a main control valve device according to the general concept of claim 1 for controlling a piston-cylinder device, in particular for actuating a movable contact part of a high-pressure switch. Background technique [0002] Patent DE 102009014421.8 proposes a valve control device in which a 3 / 2-way valve is configured as a preset valve and two 2 / 2-way valves are configured as main control valves. [0003] The patent US 5476030A discloses a valve control device with a plurality of valves of different configurations, these valves include a plurality of 2 / 2 reversing valves and a 3 / 2 reversing valve, so that the structure of the valve control device is quite complicated . [0004] Document DE 19932139 B4 discloses a valve control device of the type mentioned at the outset, in which two slide valves are provided, which are connected to each other in the manner mentioned at the ou...
