Abstract
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.
