(1) When the trigger is pulled, the compressed air expands and drives the piston forward.

(2) The force of the resulting explosion pushes the piston down the cylinder for the exhaust stroke.

(3) Each explosion would release enough force to push the piston .

(4) The cylinders have to be right and their fit with the piston rings perfect.

(5) A hydraulic hammer is basically a hydraulically powered reciprocating piston inside of a body.

(6) The stroke is the distance that the piston moves up and down.

(7) Jet engines are crucial: They're faster than piston engines and far safer.

(8) The resulting explosion pushes a piston , which is attached to a connecting rod.

(9) The piston in its cylinder rocked, trembled, didn't move.

(10) Modified piston valves were also fitted to counteract the high coal consumption as the originals became worn.

(11) The bore is often pitted and the gas piston is usually corroded.

(12) The central control circuit then sends a control signal to the driver's circuit for the accumulator piston .

(13) Adkins' solution was to affix his gas piston to the standard recoil spring plug.

(14) Then the piston moves back up to compress this fuel/air mixture.

(15) The valves and pistons on a trumpet are very delicate - and essential.

(16) Besides leaving salt deposits, rusting internal parts and causing valve damage, water in an engine also makes short work of pistons and cylinders.

(17) Another system uses hydraulic pistons that mount to a wood platform.

(18) The aluminum block has ductile iron cylinder liners and is filled with JE pistons .

(19) The five mobile panels (one flap, four sliding) are activated by hydraulic pistons .

(20) The engine's camshaft drives the pump pistons through a roll rocker arm.
