Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0030] Such as figure 1 As shown, the electro-hydraulic proportional solenoid valve of the present invention includes a valve core 1 , an oil outlet valve sleeve 2 , a guide sleeve 3 , a magnetic isolation ring 4 , a pole piece 5 , and a coil 7 . The magnetic isolation ring 4 is made of non-magnetic material, and the two ends of the magnetic isolation ring 4 are respectively welded with the guide sleeve 3 and the pole shoe 5 to form a sleeve. The oil outlet valve sleeve 2 is provided with at least one oil outlet hole 2b, and one end of the oil outlet valve sleeve 2 and the guide sleeve 3 adopt an interference fit. At least one oil inlet wedge-shaped groove 1a is provided on the end outer peripheral surface of one end of the valve core 1, a straight groove 1c communicatin...
