Latest Patents

Kurita holds a patent for an electromagnetic proportional pressure reducing valve. This invention relates to a pressure reducing valve wherein a spool is driven axially by a first plunger that moves according to the magnetization state of a first solenoid. A control port is connected to a supply port and a tank port based on the axial position of this spool. The pressure of the control port acts on the spool in the opposite direction to that of the plunger via a feedback passage. The pressure increases or decreases according to the current flowing through the first solenoid. Additionally, a second plunger is arranged in series with the first plunger, and a spring tends to push the second plunger toward the first plunger. A second magnetized solenoid keeps the second plunger held back against the restoring force of the spring, releasing it to push the first plunger when the current fails. This design ensures that even if the current supplied to the first and second solenoids is cut off, the control port maintains the predetermined pressure, thus realizing a fail-safe mechanism through a simple construction.
