ELECTRO PNEUMATIC AND ELECTROMECHANICAL ACTUATED DIAPHRAGM TYPE FLUSH VALVE FOR AIRCRAFT TOILET
A flush valve includes a housing (304) having a first end (306) and a second end (308), a piston stem (310) extending between the first end and the second end, a piston stem fore end (312) coupled to the piston stem, a first O-ring (314) and a second O-ring (316) defining a control chamber (318) therebetween, and a solenoid valve (334) in fluid communication with the control chamber. The piston stem fore end is positioned toward the second end when in a closed position. In an energized state, the solenoid valve charges a pressurized gas into the control chamber, pushing the piston stem toward the first end and into an open position.
