Abstract: A filter screen for an integrated valve is disclosed, which is inserted into an integral bore of a housing. The filter screen has a retention protrusion, which upon insertion can be put from an assembly position into a retention position.

Abstract: A setting screw connection for a mechanically or electromagnetically actuable hydraulic valve has a setting region, a setting screw with an external thread, and a setting nut with an internal thread for mutual engagement. At least one of the internal thread and external thread has a cross section which differs from a circular shape. Further, at least one of the internal thread and external thread is configured to be predominantly elastically deformed via the engagement with the respectively other thread such that at least one of the setting screw is secured against rotation at least in the setting region, and an axial play of the setting screw is prevented at least in the setting region. A hydraulic valve includes the setting screw connection, and has a valve piston which is positioned axially displaceably and is coupled axially to the setting screw connection.

Abstract: An actuating magnet is provided for a magnetic valve for a nonmagnetic pressure pipe, that is connected to at least one pole body, in which an armature is developed, and onto which at least two annular sleeves, having a ring lying between them, are slipped, in whose area a gap is situated that is developed between the armature and the pole body. Thereby, the actuating magnet may be developed in a simple manner by slipping annular sleeves and separating rings onto the pressure pipe.

Abstract: A check valve is mounted in a valve arrangement having a valve member with an annular channel and at least one bore opening into the annular channel. The check valve has a closing element configured to close the at least one bore in the annular channel. The closing element is formed of a strip shaped as a ring. The strip of the check valve is arranged in the annular channel of the valve member.

Abstract: A valve has a valve housing having a flow path for a medium with at least one bore. At least one screen is arranged in the flow path of the medium in the valve housing. The screen is a perforated plate having screen openings and is made of a strap. The valve housing has at least one annular channel and the screen is arranged on a support surface provided in the annular channel.

Abstract: A solenoid for a hydraulic valve has an armature chamber having chamber walls. A pole core forms one of the chamber walls and has an axial central bore. An armature is slidably arranged in the armature chamber. The armature has a central receptacle. An armature piston is arranged in the central receptacle of the armature and extends through the axial central bore of the pole core. The armature piston consists of a nonmagnetic material. The armature piston acts on a valve member when moved by the armature piston. The armature piston is a tubular member formed of a piece of planar sheet metal and has a radially outwardly projecting anti-stick disc that defines a minimal axial spacing between the armature and the pole core. The radially outwardly projecting anti-stick disc is formed as a monolithic part of the tubular member by parts of the sheet metal being bent radially outwardly relative to the tubular member.

Abstract: A one-piece axial seal is provided for sealing a passage at the interface between a first component and a second component, in particular a fluid conduit or a screw hole. The seal has a fastening section, comprising a projection adapted to be pressed into a bore provided in the first component, and a sealing section. So that the axial seal can take up an exactly defined position on the first component, the sealing section is prestressed in a direction towards which the projection extends.
