Problems solved by technology

However, the slit of the pressure pipe leads to a reduction in the stability of the pressure pipe and the fixing of the housing cover can cause deformation of the groove
[0006] A further disadvantage is that the embodiment of the pressure tube with grooves and external threads for fastening the end caps results in high manufacturing costs and has the consequence of complex installation

Embodiment Construction

[0025] 1 shows a simplified longitudinal sectional view of a solenoid adjusting device 1, wherein a pressure tube 2 has an end-side central thread 3, by means of which the pressure tube 2 is fastened to a not shown valve housing or the like middle. A bushing 4 with an electromagnetic coil 5 , a travel measuring system 6 and an electronic part 33 are sleeved and fastened on the pressure tube 2 .

[0026] The pressure tube 2 itself is designed in a known manner to be pressure-tight and consists of an armature tube 7 and a sensor tube 8 arranged sealingly and firmly in the armature tube 7 . The armature tube 7 has a pole piece 9 on which and in the vicinity of the central thread 3 there are first wrench faces 10 to which the non-magnetically conductive first pipe part and the magnetically conductive second part are connected. tube part.

[0027] At its free, open end, the armature tube 7 has a collar 13 for clamping the components which are fitted over the pressure tube 2 , nam...

Abstract

The invention relates to an electromagnetic regulating device (1) for a hydraulic control valve, comprising a housing (14, 15, 32) which comprises an electromagnet rotor arranged in a pressure pipe (2). Additionally, a distance measuring system (6) which detects the lift of the rotor is provided. Said pressure pipe (2) comprises a central thread (3) on one end thereof for securing onto the control valve and is made of a rotor conduit (7) and a sensor pipe which is connect thereto in a tight and secure manner. Said rotor conduit (7) lifts the rotor and supports a magnetic coil (5). Said sensor pipe (8) comprises a sensor coil (21) for detecting the way. Securing means are also provided for components which are semi-mounted on the pressure pipe (2). In the area at the end of the rotor conduit (7) orientated towards the sensor pipes (7), a collar (13) for holding the components arranged on the rotor conduit is provided and is firmly secured to said rotor conduit (7), rising above said conduit.

Description

technical field [0001] The invention relates to an electromagnetic regulating device for a hydraulic regulating valve, which has a housing with an electromagnet armature in a pressure tube; a stroke measuring system for measuring the stroke of the armature, wherein one end of the pressure tube has a Fixed to the central thread on the regulating valve, the pressure tube consists of an armature tube and a sensor tube that is sealed and fixedly connected to the armature tube, wherein the armature tube houses the armature and supports the electromagnetic coil, and the sensor tube has a sensor coil for detecting stroke ; and has a fixing device for fixing the parts on the pressure pipe. Background technique [0002] EP 0 278 227 B1 discloses a proportional solenoid with a travel measuring system, in which a pressure tube forming an armature tube and a sensor tube is accommodated in a housing. In this proportional solenoid, a solenoid coil and a sensor coil are inserted into the ...
