Abstract
Official abstract text for this publication.
A solenoid valve for controlling a fluid has a first housing part ( 2 ) and an axial guide ( 3 ) facing inwards for an armature ( 4 ) that can be displaced in the axial guide ( 3 ) under the effect of a solenoid ( 5 ) that at least partially surrounds the exterior of the first housing part ( 2 ). A return spring ( 6 ) and a closing element ( 27 ) impact a valve closing element ( 7 ). A second housing part ( 9 ) is arranged coaxially to the first housing part ( 2 ). The first housing part ( 2 ) has a reduced wall portion ( 17 ) that faces inwards towards the armature ( 4 ) and the second housing part ( 9 ) and that effects a magnetic separation of the two housing parts ( 2, 9 ) to at least some extent.
First claim
Opening claim text (preview).
What is claimed is: 1. A solenoid valve for controlling a fluid flow, comprising: a first housing part having a thin-walled sleeve being a pole tube forming an axial guide oriented toward an interior thereof; a solenoid at least partially surrounding said first housing part to an outside thereof; an armature movably mounted in said axial guide under action of said solenoid; a valve closing member being in said first housing part and being acted upon by a reset spring and a c…
