德國Rexroth力士樂換向閥技術(shù)原理

Technical rationale：
Rexroth electro-hydraulic valve works as follows: When the electromagnetic coil power, due to the rigidity of the core after the pilot relief valve spring (5) is far greater than the stiffness of the front springs 2, so in the spring force, the pilot spool 1 closed. In this case, imported high pressure oil P1, on the one hand through the main valve to the outlet port P2, on the other hand flows through the main valve orifice d6 left chamber, so as to ensure a basic balance between the hydraulic pressure spool around two main chambers, the main valve core under the action of the spring force and the hydraulic pressure is reliably closed. When the solenoid coil is energized, the pilot spool 1 left in electromagnetic force, the main valve on the oil chamber 3 through the hole in communication with the outlet d4, d6 since the throttle hole diameter is much smaller than the main spool the diameter of holes d4, thus the same fluid pressure around the main valve chamber. Since the main valve using differential structure, so the liquid pressure to the left, in order to achieve the commutation function.
