ABSTRACT:
A novel improved pinch valve for controlling the flow of fluids in an unrestricted manner in, at least, two flexible tubes, including a housing for holding a solenoid coil between its outer wall and inner cylindrical core member. The solenoid armature is a truncated cone shape which coacts with a similarly shaped opening at the end of the inner cylindrical core member to optimize the flux path of the solenoid and thus its efficiency. A tube retention member includes openings for holding the flexible tubes. A further opening in the tube retention member holds a plunger member which is captured by a retaining pin. The plunger member is secured to the solenoid armature prior to assembly of the tube retention member to the solenoid housing. The plunger member moves with the armature as the solenoid is energized and deenergized. When the solenoid is unenergized, one of the flexible tubes is compressed between a knife like edge on the plunger member and a body portion of other tube retention member. When the solenoid is energized, the tube is now compressed between the retaining pin and the body portion of the plunger member, while the previously restricted tube becomes unrestricted. Because of the design, the alternate restriction of the tubes occurs on the axis of the valve enabling improved performance for power consumed.
