This paper analyzes direct current flow (DC flow) due to double-inlet, and introduces a second orifice version pulse tube refrigerator experiment to diminish DC flow. Analysis based on some assumptions shows that DC flow through the double-inlet valve in the pulse tube refrigerator is not generally
