Answer to Question 1
Reciprocating uses pistons in a cylinder. Gas is compressed by squeezing it between the piston and a valve plate at the top of the cylinder.
Rotary uses a roller that rotates in an orbital motion within a cylinder. Gas is compressed by squeezing it between the roller and a spring-loaded vane.
Screw uses two rotating screws shaped like augers. Gas is compressed by squeezing it between the two screws
Centrifugal - has a very high-speed centrifugal impeller that spins within a housing. The gas enters the impeller in the center and is thrown outwards by centrifugal force, compressing the gas.
Scroll - has a stationary scroll and an orbiting scroll that moves within the stationary scroll. Gas is compressed by squeezing it between the two scrolls.
