Beschreibung
Zusammenfassung:	A fluid pressure proportional valve includes a valve body, a first core shaft, a second core shaft, and a driving motor. The valve body has a first orifice, a second orifice, a third orifice, and a receiving space having a valve port. The first and second core shafts are located in the receiving space. The first core shaft has a sealing portion, an abutting portion, and a flow channel. Under normal status, the sealing portion seals the valve port, and the second orifice communicates with the third orifice via the flow channel When the driving motor drives the second core shaft to move along an axial direction, the second core shaft could seal the flow channel to block the communication between the second orifice and the third orifice and push the abutting portion of the first core shaft to depart from the valve port and the sealing portion, thereby communicating the first and the second orifices.
