A fluid pressure reversing valve includes a housing, a coil carrier, a coil wound on the coil carrier, a bearing, an armature axially displaceable in the bearing, a core, a flux guiding device, a first connection bore, a control chamber, a first valve seat. A connection sleeve comprises a second connection bore, a first valve seat for a valve element of the armature, and a second valve seat for the valve element of the armature. The connection sleeve communicates with a fluid to be controlled. A third connection bore is connected with the control chamber. A valve element abuts against the first valve seat in a first position so as to form a connection between the first connection bore and the third connection bore, and against the second valve seat in a second position so as to form a connection between the third connection bore and the second connection bore.

Fluid pressure reversing valve

A solenoid valve includes a housing within which is arranged a coil wound onto a coil former, an armature, a core, and a multiple-part return path arrangement, which together form an electromagnetic circuit. The armature is configured to be movable and to act at least indirectly on a valve closure element mounted in the coil former via a bearing. The multiple-part return-path arrangement comprises at least one return-path cover section, a return-path side section and a return-path inner section. The return-path inner section is arranged in the coil former.

Solenoid valve

A solenoid valve with an electromagnetic circuit includes a return plate, a yoke, a coil wound onto a coil carrier. The coil carrier includes an internal thread and comprises a dimensionally and temperature-stable material. A core includes an outer thread. The core is disposed in the coil carrier via a direct interlocking connection. The outer thread of the core is disposed within the internal thread of the coil carrier and is configured to provide adjustment for the core. An armature is configured to be movable and to act at least indirectly on a valve-closing element. The armature is supported in the coil carrier by a supporting device.

A pressure-control valve includes a housing, a coil carrier, a coil wound on the coil carrier, a first bearing, an armature comprising a valve member. The armature is configured to be axially displaced in the first bearing. A core. A flux guiding device. A connection sleeve comprises a valve seat for the valve member. A first connection bore is configured to be connected with a tank and with the connection sleeve. A second connection bore is configured to be connected with a consumer. An end of the connection sleeve distant from the core comprises a control bore with a control member supported therein. The armature and the control member are configured to be in a force-transmitting operative connection at least in an opening direction of the pressure-control valve.

Infinitely variable pressure-control valve

An electropneumatic converter for connection with an exhaust recirculation valve in a motor vehicle. The electropneumatic converter includes a vacuum port and an atmospheric pressure port configured to connect with a valve chamber using a valve device, wherein a mixed pressure is formed in the valve chamber and supplied to a mixed pressure port. An armature is affixed to a valve body of the valve device movable in an axial direction, the valve body being connected to a suspension device, wherein the armature is displaceable in the axial direction using a solenoid. The electropneumatic converter also includes a damping element configured to dampen the axial movement of the armature and the valve device affixed thereto. The damping element includes at least one of an elastomer or a foamed material.

Vibration- and pulsation-attenuated electropneumatic converter

A holder for electro-pneumatic components for vehicles provides for a base plate with fastening elements for fastening the holder in the vehicle. Holding elements for releasable holding the electro-pneumatic components are connected to the base plate. The fixing elements each have two holding arms designed as click-in elements. Further, a fixing element in the form of a small elastic plate, such as a rubber disc, is provided. The fixing element presses the electro-pneumatic component against an abutment for a vibration-resistant fixation.
