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.

1. A fluid pressure reversing valve for a consumer comprising a fluid to be controlled, a first consumer control chamber, a second consumer control chamber, and a consumer outlet, the fluid pressure valve comprising: a coil carrier;a coil wound on the coil carrier;a bearing;an armature comprising a valve element, the armature being configured to be axially displaceable in the bearing;a core;a flux guiding device;a first connection bore;a connection sleeve comprising a second connection bore, a first valve seat for the valve element of the armature, and a second valve seat for the valve element of the armature, the second connection bore being connected with the consumer outlet and with the second consumer control chamber and being configured to communicate with the fluid to be controlled;a third connection bore connected with the first consumer control chamber; anda housing comprising a lower housing part and an upper housing part, the lower housing part comprising the connection sleeve, the first connection bore, the second connection bore, and the third connection bore, and the lower housing part being arranged in an interlocking manner or in a force-fitting manner in the upper housing part,wherein, the valve element is configured to abut 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 to abut 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,the bearing bush for the armature is provided in a part of the connection sleeve facing the core, andthe first valve seat and the second valve seat are each arranged in an opposite part of the connection sleeve facing away from the core. 2. The fluid pressure reversing valve as recited in claim 1, wherein the first valve seat is provided as a first bush element and the second valve seat is provided as a second bush element, and the first bush element and the second bush element each comprise chamfered abutment surfaces directed towards the valve element. 3. The fluid pressure reversing valve as recited in claim 1, wherein at least one of the first bush element and the second bush element is offset backward with respect to the third connection bore. 4. The fluid pressure reversing valve as recited in claim 1, further comprising a tube element and a valve interior, wherein the armature is hollow and is connected with the valve element via the tube element so that the valve interior has a pressure prevailing at the second connection bore. 5. The fluid pressure reversing valve as recited in claim 4, wherein, the armature, the tube element and the valve element are provided as multiple parts, andthe tube element is pressed into the armature. 6. The fluid pressure reversing valve as recited in claim 1, wherein, the valve element has an effective surface and the armature has an effective surface, andthe effective surface of the valve element being smaller or larger than the effective surface of the armature.
