Electromagnetically actuated directional flow valve - has valve port control element displaced by linkage with spring-biased element to couple with actuator stage

摘要

The electromagnetically actuated directional flow valve has a main bore in which a pair of screw adjusters (32, 34) are located. Each adjuster has a bore which receives pins (20, 42) which contact a ball valve element (8) sitting on valve seats to control the flow path (24). Displacement of the pins is provided by an `L' shaped linkage (68), hinged at the bottom end (58). The top end of the linkage is in contact with a ball (70) within a cup shaped sleeve (80) having a stack of spring discs (122). The discs maintain contact with the actuator pin (72) of a solenoid. ADVANTAGE - Simplified assembly, vibration free.
