Proportional solenoid control valve
First Claim
1. A proportional solenoid control valve comprising:
- a solenoid;
a magnetic movable member which is applied a magnetic attraction force by the solenoid; and
a flat spring for engaging its outer periphery section with non-magnetic cylindrical member for guiding the magnetic movable member, and for engaging its inner periphery section with the magnetic movable member so as to balance in power with the magnetic movable member due to the magnetic attraction force.

Abstract
A proportional solenoid control valve comprises a flat square spring which is wide in maintaining width with respect to displacement of a spring having a greater spring constant, so that accurate control of fluid is realized. The flat square spring has four tubs and is supported with respect to a step face with outer peripheral section thereof. The valve further comprises a sealing mechanism loaded with rubber resilience compensates instability of armature construction and resilient sealing section. The spring constant of the flat square spring is improved by strengthening the magnetic force, thus hysteresis can be made to be smaller.
