20100186689 | INTERSTAGE VALVE IN DOUBLE PISTON CYCLE ENGINE - An interstage valve for fluidly coupling two chambers of a double-piston engine is disclosed. The interstage valve may include a main valve body, a seal, and an electric coil. When closed, the seal is coupled to the main valve body as a result of electromagnetic forces generated by the electrical coil. The interstage valve is opened when the pressure differential between the engine chambers exceeds the electromagnetic forces. As the interstage valve opens, the electromagnetic forces diminish. The electromagnetic valve moves from the open state to the closed state when the pressure differential reverses. As the seal moves toward the main valve body, the electromagnetic forces increase, coupling the seal to the main valve body. | 07-29-2010 |
