Title: Solenoid proportional pressure control valve
Inventor: ICHIHASHI KOJI
IPC: F16K31/06
Filed: 1988-11-21
Abstract: PURPOSE:To make differential pressure in both pressures accurately controllable without being affected by any fluctuation in the primary pressure by moving each spool in the opposite direction to each other by receiving each port pressure at both primary and secondary sides, and setting each effective active area of both pressure receiving surfaces equally. CONSTITUTION:When current-energization is started to an exciting coil 10, an armature 12 gets a right thrust with generated magnetic force out of this coil 10, and thereby a spool 4 is pressed to the right. Then, a primary side port 21 and a secondary side port 22 are interconnected with each other, and pressure in the port 22 increases. Next, if an impressed current for the coil 10 is increased, the spool 4 is further moved to the right and an interconnecting passage area between these ports 21 and 22 is enlarged, thus pressure in the port 22 increases as well. Here a position of the spool 4 is determined so as to satisfy an equation I, through which the pressure in the port 22 is controlled to that proportioned to an input current value of a solenoid actuator part A. In this case, when the equation I is rewritten to an equation II, fluctuations in primary pressure P1 are 1:1 as shown in the equation II, affecting secondary pressure P2, therefore differential pressure (P1-P2) is accurately controlled according to an input value.
