Abstract
The invention relates to a screw-in valve comprising a screw-in component, a sleeve with at least two connection openings to which a pressure load can be alternately applied, and a valve piston held for axial displacement in the sleeve for opening and closing a flow connection between the connection openings. In order to further develop the screw-in valve so as to reduce the risk of impairing movement of the valve piston on account of misalignment of the screw-in component, it is proposed, in accordance with the invention, that the sleeve be mounted so as to be axially immovable but displaceable and/or pivotable perpendicularly to the screw-in direction of the screw-in component relative to the screw-in component.

Screw-in valve comprising:
- a screw-in component,
- a sleeve with at least two connection openings to which a pressure load can be alternately applied,
- a valve piston held for axial displacement in said sleeve for opening and closing a flow connection between said connection openings, said sleeve being mounted so as to be axially immovable, and
- means to allow said sleeve to be displaceable and/or pivotable perpendicularly to a screw-in direction of the screw-in component relative to the screw-in component.
