Beschreibung
Zusammenfassung:	The invention discloses a proportional flow electromagnetic valve. The proportional flow electromagnetic valve comprises a proportional electromagnet, a pressure control valve core, a flow control valve core, a valve sleeve, a flow control spring and a plug. The electromagnetic force of the electromagnetic valve does not directly control the flow, but is used for controlling the hydraulic pressureof one pressure containing cavity in the electromagnetic valve. The size of a throttling hole is adjusted by controlling the positions of the valve cores through the balance between the hydraulic pressure in the containing cavity and the spring force so as to control the size of the flow. 本发明公开了种比例流量电磁阀，包括比例电磁铁、控压阀芯、控流阀芯、阀套、控流弹簧和堵头。该电磁阀的电磁力不直接控制流量，而是用来控制电磁阀内部的个压力容腔的液压，通过该容腔内液压力与弹簧力的平衡控制阀芯的位置从而调节节流孔的大小来控制流量的大小。
