Zusammenfassung:	Pressure cycle operated apparatus and methods. A method of actuating a 5 firing head includes the steps of: reciprocably displacing an actuator piston of the tiring head, the displacing step including the piston being alternately pressure balanced and unbalanced; and igniting a combustible material in response to the piston displacing step. A method of generating electricity includes: reciprocably displacing a piston, the displacing step including the piston being alternately pressure 10 balanced and unbalanced; and generating electricity in response to the piston displacing step. A tiring head includes an actuator piston separating at least two chambers; a check valve which permits one-way flow between the chambers; a flow restrictor which restricts flow between the chambers; a biasing device which biases the piston toward one of the chambers; and a firing pin releasing device which 15 releases a tiring pin in response to displacement of the piston. 06/07/15,dh-22857 - abstract - cdm.docx,2
